custom core controller not found

Question

I created a core controller named Role_Admin and set the config prefix

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

Here is the code for the Role_Admin.php in the core folder

class Role_Admin extends CI_Controller {
    function __construct() {

    }
}

In the controller folder when I write

class admin extends Role_Admin { ... }

I get

Fatal error: Class 'Role_Admin' not found

Is something wrong in what I am doing.

edit: (i created a quick fix that is much better, any new core file that you create just extend the MY_Controller. Then in your controller directory you can extend any Core controller that you created

class MY_Controller extends CI_Controller {

        function __construct() {
            parent::__construct();

            //include custom core classes
            $core_path = DOCUMENT_ROOT . '/application/core';
            $this->load->helper('file');

            foreach(get_filenames($core_path) as $file) {
                if ($file != 'MY_Controller.php') {
                    if(file_exists($file)) {
                        include_once($file);
                    }
                }
            }
        }

}

where have you put this controller and which version are you using? — Muhammad Raheel

You have saved Role_Admin.php in application/core/ and not in system/core/, right ? — air4x

The setting you have for $config['subclass_prefix'] is fine, but your file name is incorrect. CI is looking for the file Role_Controller.php, not Role_Admin.php.

There's an easier way to do this, and although it might appear to be a hack it is totally legit. Go back to the MY_ prefix, create MY_Controller.php, and in that file, just define the controller classes you want to use. You actually don't even need a MY_Controller class. Example:

// application/core/MY_Controller.php
class Role_Admin extends CI_Controller {}
class AnotherClass extends Role_Admin {}
class SomeOtherClass extends AnotherClass {}

All these classes will be available for your controllers to extend.

have all these classes in that one file?

Yes, you can. It's what I do, but my base controllers are pretty lean.

Does my answer satisfy your question or is there still a problem? The issue with "custom core controller not found" was that you needed Role_Controller.php, not Role_Admin.php., if that was not the case then do let me know. The design of your classes is a separate concern.
