2 This method does not work because you put a not sub variable in URL, so I think you need to change to this :

URL syntaxin this example we have this url www.htmlexample.org/phpexample.php Before passing a variable using the url first add a '?' to the end of the normal url www.htmlexample.org/phpexample.php? after the ? add the name of the variable www.htmlexample.org/phpexample.php?varName put an "=" then add the value assigned to the variable name www.htmlexample.org/phpexample.php?varName=value to pass more then one variable repeat above but only have '?' before the first one and a '&' in between each new variable www.htmlexample.org/phpexample.php?varName=value&othervarName=othervalue Getting the variablesTo get the variable values from the url use the $_GET method for example to get the value of the variable varName use $_GET["varName"] use $_GET the same as any other method Examplethis is an example of passing a string variable tom and int variable 22 to the php script then using the 2 variables in the webpage www.htmlexample.org/phpexample.php?name=tom&age=22 echo " Name " . $_GET["name"] . "";echo" Age " . $_GET["age"] . "";How can I pass POST parameters in a URL?You could use a button instead of an anchor and just style the button to look like a link. That way you could have your values in hidden fields inside the same form to be sent via POST. In addition to what Ben said, you can also let the link be a dummy and have it execute a javascript that submits a hidden form.
