I wrote up an article showing how you do this.

You need to create an __autoload() function in your config.php or directly include the base controller above the class definition.


This is pretty easy. Do the following:

  1. Go to the following directory: your_ci_app/application/core/ and create a php file called MY_Controller.php (this file will be where your top parent classes will reside)
  2. Open MY_Controller.php and add your multiple classes, like so:

    class Admin_Parent extends CI_Controller {
        public function __construct() {
            parent::__construct();
        }
    
        public function test() {
            var_dump("from Admin_Parent");
        }
    }
    
    class User_Parent extends CI_Controller {
    
        public function __construct() {
            parent::__construct();
        }
    
        public function test(){
            var_dump("from User_Parent");
        }
    
    }
    
  3. Create your children controllers under this directory your_ci_app/application/controllers/ . I will call it adminchild.php

  4. Open adminchild.php and create your controller code, make sure to extend the name of the parent class, like so:

    class Adminchild extends Admin_Parent {
    
        function __construct() {
            parent::__construct();
        }
    
        function test() {
            parent::test();
        }
    
    }
