Extending CodeIgniter core classes
to allow any new class . means which class are note defined in system/core solution could be as follow.
Try putting below function at the bottom of config file
/application/config/config.phpfunction __autoload($class) { if(strpos($class, 'CI_') !== 0) { @include_once( APPPATH . 'core/'. $class . '.php' ); } }
Here is a good explanation as to why you can't do it the way you have described. Essentially CodeIgniter looks for ['subclass_prefix'] . $Classname, e.g. 'MY_' . 'Controller'. And here is the same question for CI2
Solution:
Put both MY_Controller and MY_AdminController in MY_Controller.php
MY_Controller.php
class MY_Controller extends CI_Controller { public function __construct() { parent::__construct(); } ...}class MY_AdminController extends CI_Controller { public function __construct() { parent::__construct(); } ...}
