How pass multiple values by link in php?

Pretty simple but another said you dont pass session variables through the url bar 1.You dont need to because a session is passed throughout the whole website from header when you put in header file 2.security risks
Here is first page code

$url = "//localhost/main.php?email=" . urlencode[$email_address] . "&eventid=" . urlencode[$event_id];

2nd page when getting the variables from the url bar is:

if[isset[$_GET['email']] && !empty[$_GET['email']] AND isset[$_GET['eventid']] && !empty[$_GET['eventid']]]{ ////do whatever here }

Now if you want to do it the proper way of using the session you created then ignore my above code and call the session variables on the second page for instance create a session on the first page lets say for example:

 $_SESSION['WEB_SES'] = $email_address . "^" . $event_id;

obvious that you would have already assigned values to the session variables in the code above, you can call the session name whatever you want to i just used the example web_ses , the second page all you need to do is start a session and see if the session is there and check the variables and do whatever with them, example:

 session_start[];
 if [isset[$_SESSION['WEB_SES']]]{
 $Array = explode["^", $_SESSION['WEB_SES']];
 $email = $Array[0];
 $event_id = $Array[1]
 echo "$email";
 echo "$event_id";
 }

Like I said before the good thing about sessions are they can be carried throughout the entire website if this type of code in put in the header file that gets called upon on all pages that load, you can simple use the variable wherever and whenever. Hope this helps :]

I passed two parameters in the URL. Now I need to retrieve the parameters log_id and dogID onto the next page to process a form.
But I can retrieve the first parameter but i cannot retrieve the second parameter.

Im using

    $log_id= $_SESSION["userid"]; 
    $dogID = $_SESSION["dogID"]; 

Is there another way to get this?

Hi,

can you show the previous step, i.e. the code used to set the session variables?

If you append parameters to the landing page:

dogReview.php?u=USER&dogID=123

Then you can access those values by using $_GET:

$user  = $_GET['u'];
$dogID = $_GET['dogID'];

$_SESSION, instead, is reserved to values set in the session handler.
