How to create two parent controllers in Codeigniter?

Question

I want to create two parent controllers: one for admin and one for user site. They have to extend a regular Controller class but each of them has to do different things.

Answer 1

You can make a MY_AdminController and a MY_UserController in system/application/libaries and use those to extend the rest of your controllers.

E.g.:

class Register extends MY_UserController
{
    // Implementation
}

And:

class ManageUsers extends MY_AdminController
{
    // Implementation
}

Answer 2

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.
