Codeigniter - extending controller does not work

Question

I am trying to extend a controller with my own class which extends the default CI_Controller class. Except it doesn't work.

It says it can't find my sub-class. My subclass is located in application/core and is named My_Control_Panel.

My class that extends on my sub-class:

if (!defined('BASEPATH')) exit('No direct script access allowed');

class Developers extends My_Control_Panel
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper('form');
        $this->load->helper('url');
        $this->load->database();

        $this->checkIfLoggedIn();
        $this->checkIfAllowedToViewPage();
}

My sub-class:

if (!defined('BASEPATH')) exit('No direct script access allowed');

class My_Control_Panel extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
    }
}

It keeps saying it can't find my sub-class, while it should work.

you should name your file like this My_Controller.php inside your core folder and then you type your code like

if (!defined('BASEPATH')) exit('No direct script access allowed');

class My_Control_Panel extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
    }
}

and this is the right way to do it in CodeIgniter, not as mentioned in the first answer with the include one ..

can I rename the My_Controller.php file into something like My_Form.php?

no you cants, since this is related to your Controllers, but if you want to extend CI_Form, then yes you can Call it My_Form

If you want CI to pick up your extended class you will have to name it MY_Controller. The MY_ part is configurable, but the other parts are not.

The MY_ part comes form the config/config.php:

$config['subclass_prefix'] = 'MY_';

Yeah, I tried changing it and stuff, but it couldn't find my sub-class anyhow

complex857 Over a year ago

This usually ends up beeing a lower/uppercase problem, your example has My with lowercase y. Maybe that's the reason. (or could be your config has My_)

Sorry about that, was a copy mistake. :) In my code it is MY_

You'll need to include the parent class (My_Control_Panel) in the subclass (Developers), like so:

if (!defined('BASEPATH')) exit('No direct script access allowed');

include_once '../path/to/mycontrolpanel.php';

class Developers extends My_Control_Panel
{
    // whatever
}

But that wasn't mentioned in de userguide of CodeIgniter. Are you sure this is the correct way?
