In this example, we will show how we can use the jQuery UI with AJAX to call a CI AJAX controller method to collect the user feedback, and submit it without refreshing/rendering a page.

auth.php: No change here
ajax_handler.php: This is the new AJAX handler controller
users_model.php: This is the extended user ...
