Is there a way of detecting POST data in URL requests before routing them?

BTW, $_POST is a superglogal and is always defined so using isset($_POST) wont work. Better to check if its an ajax request. If you use CI2, you can use what kirkaracha told you or simply put this:

Code:

define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');

..to application/config/constants.php

With that constant its easy to know if its an ajax request or not.
