Question

So I’m trying to extend the input library (CI 2.1.1), and when I call my custom save query function, its saying the function doesn’t exist.

File: MY_Input.php, in the applications/libraries folder:_

class MY_Input extends CI_Input {
 var $CI;

function __construct() {
    parent::__construct();
    $this->CI =& get_instance();
}

function save_query($query_array) {
    $this->CI->db->insert('ci_query', array('query_string' => http_build_query($query_array)));
 }
}

And in the controller I’m calling the function like this

$query_id = $this->input->save_query($query_array);

So what on earth am I doing wrong that it’s giving me this error:_

Fatal error: Call to undefined method CI_Input::save_query() in ....

Can’t see why it’s not working, I even checked the user guide and according to it I guess I’m doing it right. :/

The CI_Input class is a core library (new thing in CI2.0.0). You will have to put your MY_Input.php file under application/core/ to make the framework pick it up.

When in doubt, look for the original class under system/core or system/libraries and mirror it under application/.
