Jquery ajax success function returns null?

Maybe you need this:

Code:

// Define Ajax Request - Place in application/config/constants.php
define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');

// then check using this:
if ( ! IS_AJAX)
{
    // do this, it is not an AJAX call!
}
else
{
    // it is an AJAX call!
}
