如何为codeigniter中的所有子控制器组织主控制器

Question

I want to make something like this:

Main_Controller -> {


   child1_controller

   child2_controller

   child3_controller


}

the purpose is to execute the constructor of the Main class everytime the child classes have been executed, it looks like some kind of multi extending, for example if i want to check in the main constructor wheter is admin or not, but the problem is when i do that

child1_controller extends Main_Controller

i get an error Class 'Main_Controller' not found

Answer 1

Use the built in core class extending mechanism, if you name your base controller class appropriately (with the default prefix MY_) and put it under application/core CI should pick it up.

Once you got your MY_Controller set up, you can make your child controllers under application/controllers/ extend that, and call for parent::__construct() in their __construct.
