CodeIgniter PHP Framework - Need to get query string

Question

I\'m creating an e-commerce site using CodeIgniter.

How should I get the query string?

I am using a Saferpay payment gateway. The gateway response will be li

You can create a pre_system hook. In the hook class you create, you can grab the desired query params and add them to the $_POST for normal CI processing. I did this for a jQuery Ajax helper.

For instance:

(Name this file autocomplete.php or whatever you put as the file name in the hook)

 'Autocomplete',
                'function' => 'override_get',
                                'filename' => 'autocomplete.php',
                                'filepath' => 'hooks',
                                'params'   => array()
                                );

*                               
* 
*/

class Autocomplete {
    function override_get() {
        if (strlen($_SERVER['QUERY_STRING']) > 0) {
            $temp = @array();
            parse_str($_SERVER['QUERY_STRING'], $temp);
            if (array_key_exists('q', $temp) && array_key_exists('limit', $temp) && array_key_exists('timestamp', $temp)) {
                $_POST['q'] = $temp['q'];
                $_POST['limit'] = $temp['limit'];
                $_POST['timestamp'] = $temp['timestamp'];
                $_SERVER['QUERY_STRING'] = "";
                $_SERVER['REDIRECT_QUERY_STRING'] = "";
                $_GET = @array();
                $url = strpos($_SERVER['REQUEST_URI'], '?');
                if ($url > -1) {
                    $_SERVER['REQUEST_URI'] = substr($_SERVER['REQUEST_URI'], 0, $url);
                }
            }
        }
    }
}
