1, Magic methods là gì.
-Magic methods là các phương thức đặc biệt được tạo ra nhằm giải quyết các vấn đề về sự kiện trong chương trình [cụ thể là với class], và đối với PHP cũng thế.
-Từ đầu series đến giờ thực ra các bạn cũng đã được giới thiệu qua về magic methods rồi, phương thức khởi tạo và phương thức hủy trong bài số 6 chính là magic methods.
2, Ưu nhược điểm của magic methods.
-Bất kì một cái gì đó đều có ưu và nhược điểm cả [không có gì là hoàn hảo].
Ưu điểm
-Từ khái niệm trên thì các bạn chắc cũng có thể nhận ra các ưu điểm của nó rồi chứ? nó gồm có các ưu điểm như sau:
- Giúp cho chúng ta tùy biến được các hành vi.
- Nó giúp cho chúng ta có thể khởi tạo một đối tượng theo cách mình muốn.
Nhược điểm
- Một magic methods có tốc độ chậm hơn các phương thức bình thường.
3, Các magic method trong PHP.
-Trong PHP có hỗ trợ chúng ta 15 magic method với từng chức năng khác nhau:
+ __construct[]: gọi khi khởi tạo đối tượng.
+ __destruct[]: goij khi hủy đối tượng.
+ __set[]: gọi khi ta truyền dữ liệu cho một thuộc tính không được phép truy cập.
+ __get[]: khi đọc dữ liệu từ một thuộc tính không được phép truy cập.
+ __isset[]: được gọi khi gọi hàm isset[] hoặc empty[] trên một thuộc tính không được phép truy cập.
+ __unset[]: được gọi khi hàm unset[] được sử dụng trong một thuộc tính không được phép truy cập.
+ __call[]:được gọi khi ta gọi một phương thức không được phép truy cập trong phạm vi của một đối tượng.
+ __destruct[]0: được kích hoạt khi ta gọi một phương thức không được phép truy cập trong phạm vi của một phương thức tĩnh.
+ __destruct[]1: phương thức này giúp class chỉ định xem sẽ in ra cái gì khi nó được dùng.
+ __destruct[]2:phương thức này được gọi khi một lệnh cố gắng gọi một đối tượng như một hàm.
+ __destruct[]3: được gọi khi __destruct[]4 một đối tượng.
+ __destruct[]5: được gọi khi __destruct[]6 đối tượng.
+ __destruct[]7:
+ __destruct[]8: được sử dụng khi chúng ta clone một object.
+ __destruct[]9: được gọi khi chúng ta sử dụng hàm __set[]0.
- Hiện tại thì trên blog của mình đã có đầy đủ các bài hướng dẫn về từng magic methods, các bạn có thể tham khảo thêm ở đây.
3, Lời kết.
-Qua bài này mình đã nêu ra được khai niệm của magic methods và danh sách các magic methods trong PHP rồi, nhưng hiện tại thì mình chưa có bài viết nào hướng dẫn cụ thể về cách sử dụng của từng hàm[ sẽ viết sau] nên các bạn chịu khó đọc tài liệu tiếng anh nhé.
Laravel provides several different approaches to validate your application's incoming data. It is most common to use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Laravel includes a wide variety of convenient validation rules that you may apply to data, even providing the ability to validate if values are unique in a given database table. We'll cover each of these validation rules in detail so that you are familiar with all of Laravel's validation features.
Validation Quickstart
To learn about Laravel's powerful validation features, let's look at a complete example of validating a form and displaying the error messages back to the user. By reading this high-level overview, you'll be able to gain a good general understanding of how to validate incoming request data using Laravel:
Defining The Routes
First, let's assume we have the following routes defined in our
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
use App\Http\Controllers\PostController;
Route::get['/post/create', [PostController::class, 'create']];
Route::post['/post', [PostController::class, 'store']];
The
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Creating The Controller
Next, let's take a look at a simple controller that handles incoming requests to these routes. We'll leave the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Writing The Validation Logic
Now we are ready to fill in our
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
If validation fails during a traditional HTTP request, a redirect response to the previous URL will be generated. If the incoming request is an XHR request, a JSON response containing the validation error messages will be returned.
To get a better understanding of the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
As you can see, the validation rules are passed into the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Alternatively, validation rules may be specified as arrays of rules instead of a single
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
In addition, you may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Stopping On First Validation Failure
Sometimes you may wish to stop running validation rules on an attribute after the first validation failure. To do so, assign the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
'title' => 'bail|required|unique:posts|max:255',
In this example, if the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
A Note On Nested Attributes
If the incoming HTTP request contains "nested" field data, you may specify these fields in your validation rules using "dot" syntax:
'title' => 'required|unique:posts|max:255',
'author.name' => 'required',
'author.description' => 'required',
On the other hand, if your field name contains a literal period, you can explicitly prevent this from being interpreted as "dot" syntax by escaping the period with a backslash:
'title' => 'required|unique:posts|max:255',
Displaying The Validation Errors
So, what if the incoming request fields do not pass the given validation rules? As mentioned previously, Laravel will automatically redirect the user back to their previous location. In addition, all of the validation errors and request input will automatically be flashed to the session.
An
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
So, in our example, the user will be redirected to our controller's
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
@foreach [$errors->all[] as $error]
Customizing The Error Messages
Laravel's built-in validation rules each have an error message that is located in your application's
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
In addition, you may copy this file to another translation language directory to translate the messages for your application's language. To learn more about Laravel localization, check out the complete localization documentation.
XHR Requests & Validation
In this example, we used a traditional form to send data to the application. However, many applications receive XHR requests from a JavaScript powered frontend. When using the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
The namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
48 Directive
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
You may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
If you are using named error bags, you may pass the name of the error bag as the second argument to the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Repopulating Forms
When Laravel generates a redirect response due to a validation error, the framework will automatically flash all of the request's input to the session. This is done so that you may conveniently access the input during the next request and repopulate the form that the user attempted to submit.
To retrieve flashed input from the previous request, invoke the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Laravel also provides a global
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...

* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Below, you can review an example of the JSON response format for validation errors. Note that nested error keys are flattened into "dot" notation format:
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Form Request Validation
Creating Form Requests
For more complex validation scenarios, you may wish to create a "form request". Form requests are custom request classes that encapsulate their own validation and authorization logic. To create a form request class, you may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
The generated form request class will be placed in the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
As you might have guessed, the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Note
You may type-hint any dependencies you require within the74 method's signature. They will automatically be resolved via the Laravel service container.namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
So, how are the validation rules evaluated? All you need to do is type-hint the request on your controller method. The incoming form request is validated before the controller method is called, meaning you do not need to clutter your controller with any validation logic:
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
If validation fails, a redirect response will be generated to send the user back to their previous location. The errors will also be flashed to the session so they are available for display. If the request was an XHR request, an HTTP response with a 422 status code will be returned to the user including a JSON representation of the validation errors.
Adding After Hooks To Form Requests
If you would like to add an "after" validation hook to a form request, you may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Stopping On First Validation Failure Attribute
By adding a
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Customizing The Redirect Location
As previously discussed, a redirect response will be generated to send the user back to their previous location when form request validation fails. However, you are free to customize this behavior. To do so, define a
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Or, if you would like to redirect users to a named route, you may define a
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Authorizing Form Requests
The form request class also contains an
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Since all form requests extend the base Laravel request class, we may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Therefore, if your application is taking advantage of route model binding, your code may be made even more succinct by accessing the resolved model as a property of the request:
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
If the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
If you plan to handle authorization logic for the request in another part of your application, you may simply return
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Note
You may type-hint any dependencies you need within the73 method's signature. They will automatically be resolved via the Laravel service container.namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Customizing The Error Messages
You may customize the error messages used by the form request by overriding the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Customizing The Validation Attributes
Many of Laravel's built-in validation rule error messages contain an
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Preparing Input For Validation
If you need to prepare or sanitize any data from the request before you apply your validation rules, you may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Manually Creating Validators
If you do not want to use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
The first argument passed to the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
After determining whether the request validation failed, you may use the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Stopping On First Validation Failure
The
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Automatic Redirection
If you would like to create a validator instance manually but still take advantage of the automatic redirection offered by the HTTP request's
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
You may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Named Error Bags
If you have multiple forms on a single page, you may wish to name the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
You may then access the named
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Customizing The Error Messages
If needed, you may provide custom error messages that a validator instance should use instead of the default error messages provided by Laravel. There are several ways to specify custom messages. First, you may pass the custom messages as the third argument to the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
In this example, the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Specifying A Custom Message For A Given Attribute
Sometimes you may wish to specify a custom error message only for a specific attribute. You may do so using "dot" notation. Specify the attribute's name first, followed by the rule:
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Specifying Custom Attribute Values
Many of Laravel's built-in error messages include an
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
After Validation Hook
You may also attach callbacks to be run after validation is completed. This allows you to easily perform further validation and even add more error messages to the message collection. To get started, call the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Working With Validated Input
After validating incoming request data using a form request or a manually created validator instance, you may wish to retrieve the incoming request data that actually underwent validation. This can be accomplished in several ways. First, you may call the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Alternatively, you may call the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]

Specifying Custom Messages In Language Files
Laravel's built-in validation rules each have an error message that is located in your application's
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
In addition, you may copy this file to another translation language directory to translate the messages for your application's language. To learn more about Laravel localization, check out the complete localization documentation.
Custom Messages For Specific Attributes
You may customize the error messages used for specified attribute and rule combinations within your application's validation language files. To do so, add your message customizations to the

different:field
The field under validation must have a different value than field.
digits:value
The integer under validation must have an exact length of value.
digits_between:min,max
The integer validation must have a length between the given min and max.
dimensions
The file under validation must be an image meeting the dimension constraints as specified by the rule's parameters:
'title' => 'required|unique:posts|max:255',
'author.name' => 'required',
'author.description' => 'required',
Available constraints are: min_width, max_width, min_height, max_height, width, height, ratio.
A ratio constraint should be represented as width divided by height. This can be specified either by a fraction like
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validate[[

exists:table,column
The field under validation must exist in a given database table.
Basic Usage Of Exists Rule
If the
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
Specifying A Custom Column Name
You may explicitly specify the database column name that should be used by the validation rule by placing it after the database table name:
'title' => 'required|unique:posts|max:255',
'author.name' => 'required',
'author.description' => 'required',
Occasionally, you may need to specify a specific database connection to be used for the
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
'title' => 'required|unique:posts|max:255',
'author.name' => 'required',
'author.description' => 'required',
Instead of specifying the table name directly, you may specify the Eloquent model which should be used to determine the table name:
'title' => 'required|unique:posts|max:255',
'author.name' => 'required',
'author.description' => 'required',
If you would like to customize the query executed by the validation rule, you may use the

mimes:foo,bar,...
The file under validation must have a MIME type corresponding to one of the listed extensions.
Basic Usage Of MIME Rule
'title' => 'required|unique:posts|max:255',

'title' => ['required', 'unique:posts', 'max:255'],
'title' => 'required|unique:posts|max:255',
starts_with:foo,bar,...
The field under validation must start with one of the given values.
string
The field under validation must be a string. If you would like to allow the field to also be
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
timezone
The field under validation must be a valid timezone identifier according to the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
unique:table,column
The field under validation must not exist within the given database table.
Specifying A Custom Table / Column Name:
Instead of specifying the table name directly, you may specify the Eloquent model which should be used to determine the table name:
0
@foreach [$errors->all[] as $error]
The
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
1
@foreach [$errors->all[] as $error]
Specifying A Custom Database Connection
Occasionally, you may need to set a custom connection for database queries made by the Validator. To accomplish this, you may prepend the connection name to the table name:
2
@foreach [$errors->all[] as $error]
Forcing A Unique Rule To Ignore A Given ID:
Sometimes, you may wish to ignore a given ID during unique validation. For example, consider an "update profile" screen that includes the user's name, email address, and location. You will probably want to verify that the email address is unique. However, if the user only changes the name field and not the email field, you do not want a validation error to be thrown because the user is already the owner of the email address in question.
To instruct the validator to ignore the user's ID, we'll use the
$validatedData = $request->validate[[
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
3
@foreach [$errors->all[] as $error]
Warning
You should never pass any user controlled request input into the13 method. Instead, you should only pass a system generated unique ID such as an auto-incrementing ID or UUID from an Eloquent model instance. Otherwise, your application will be vulnerable to an SQL injection attack.$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Instead of passing the model key's value to the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
4
@foreach [$errors->all[] as $error]
If your table uses a primary key column name other than
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
5
@foreach [$errors->all[] as $error]
By default, the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
6
@foreach [$errors->all[] as $error]
Adding Additional Where Clauses:
You may specify additional query conditions by customizing the query using the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
7
@foreach [$errors->all[] as $error]
uppercase:field
The field under validation must be uppercase.
url
The field under validation must be a valid URL.
uuid
The field under validation must be a valid RFC 4122 [version 1, 3, 4, or 5] universally unique identifier [UUID].
Conditionally Adding Rules
Skipping Validation When Fields Have Certain Values
You may occasionally wish to not validate a given field if another field has a given value. You may accomplish this using the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
8
@foreach [$errors->all[] as $error]
Alternatively, you may use the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
9
@foreach [$errors->all[] as $error]
Validating When Present
In some situations, you may wish to run validation checks against a field only if that field is present in the data being validated. To quickly accomplish this, add the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
In the example above, the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Note
If you are attempting to validate a field that should always be present but may be empty, check out this note on optional fields.
Complex Conditional Validation
Sometimes you may wish to add validation rules based on more complex conditional logic. For example, you may wish to require a given field only if another field has a greater value than 100. Or, you may need two fields to have a given value only when another field is present. Adding these validation rules doesn't have to be a pain. First, create a
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Let's assume our web application is for game collectors. If a game collector registers with our application and they own more than 100 games, we want them to explain why they own so many games. For example, perhaps they run a game resale shop, or maybe they just enjoy collecting games. To conditionally add this requirement, we can use the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
The first argument passed to the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Note
The36 parameter passed to your closure will be an instance of$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
37 and may be used to access your input and files under validation.$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Complex Conditional Array Validation
Sometimes you may want to validate a field based on another field in the same nested array whose index you do not know. In these situations, you may allow your closure to receive a second argument which will be the current individual item in the array being validated:
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Like the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Validating Arrays
As discussed in the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
In general, you should always specify the array keys that are allowed to be present within your array. Otherwise, the validator's
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Validating Nested Array Input
Validating nested array based form input fields doesn't have to be a pain. You may use "dot notation" to validate attributes within an array. For example, if the incoming HTTP request contains a
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
You may also validate each element of an array. For example, to validate that each email in a given array input field is unique, you may do the following:
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Likewise, you may use the
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
$validated = $request->validate[[
'title' => 'required|unique:posts|max:255',
// The blog post is valid...
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Accessing Nested Array Data
Sometimes you may need to access the value for a given nested array element when assigning validation rules to the attribute. You may accomplish this using the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
Post Title
class="@error['title'] is-invalid @enderror">
{{ $message }}
Error Message Indexes & Positions
When validating arrays, you may want to reference the index or position of a particular item that failed validation within the error message displayed by your application. To accomplish this, you may include the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Given the example above, validation will fail and the user will be presented with the following error of "Please describe photo #2."
Validating Files
Laravel provides a variety of validation rules that may be used to validate uploaded files, such as
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
If your application accepts images uploaded by your users, you may use the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Note
More information regarding validating image dimensions may be found in the dimension rule documentation.
File Types
Even though you only need to specify the extensions when invoking the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
//svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
Validating Passwords
To ensure that passwords have an adequate level of complexity, you may use Laravel's
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
The
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
In addition, you may ensure that a password has not been compromised in a public password data breach leak using the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Internally, the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
By default, if a password appears at least once in a data leak, it will be considered compromised. You can customize this threshold using the first argument of the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Of course, you may chain all the methods in the examples above:
Defining Default Password Rules
You may find it convenient to specify the default validation rules for passwords in a single location of your application. You can easily accomplish this using the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Then, when you would like to apply the default rules to a particular password undergoing validation, you may invoke the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Occasionally, you may want to attach additional validation rules to your default password validation rules. You may use the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Custom Validation Rules
Using Rule Objects
Laravel provides a variety of helpful validation rules; however, you may wish to specify some of your own. One method of registering custom validation rules is using rule objects. To generate a new rule object, you may use the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Once the rule has been created, we are ready to define its behavior. A rule object contains a single method:
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Once the rule has been defined, you may attach it to a validator by passing an instance of the rule object with your other validation rules:
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Translating Validation Messages
Instead of providing a literal error message to the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
If necessary, you may provide placeholder replacements and the preferred language as the first and second arguments to the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Accessing Additional Data
If your custom validation rule class needs to access all of the other data undergoing validation, your rule class may implement the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Or, if your validation rule requires access to the validator instance performing the validation, you may implement the
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Using Closures
If you only need the functionality of a custom rule once throughout your application, you may use a closure instead of a rule object. The closure receives the attribute's name, the attribute's value, and a
$validatedData = $request->validateWithBag['post', [
'title' => ['required', 'unique:posts', 'max:255'],
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
Implicit Rules
By default, when an attribute being validated is not present or contains an empty string, normal validation rules, including custom rules, are not run. For example, the
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
* @return \Illuminate\View\View
return view['post.create'];
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
public function store[Request $request]
// Validate and store the blog post...
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class PostController extends Controller
* Show the form to create a new blog post.
