--Is there a controller hierarchy ? - El Forum - 10-15-2007

Hi I am a newbie to CI. I created a controller which extends the Controller:
class BaseSessionController extends Controller {
// some logic here
}
Then I tried to create another controller class which extends the BaseSessionController:
class SubController extends BaseSessionController {
// some logic here
}
These two controllers are in two different php files -- both in the controllers folder. It seems that BaseSessionController could not be recognized by SubController . I am wondering if I have to manually include the BaseSessionController script file in my SubController script, using require() or require_once().

yep, you have to manually include it unfortunately

If it's not being used as a 'real' controller (i.e. you're only sub-classing it), you could stick it in the /libraries folder - that way you can autoload it and won't have to require/include it.

I tried the library approach, but it can only be accessed through composition but not inheritance.
Specifically, I first created a script:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Someclass {
function some_function()
{
}
}
?>
Then put it into the library folder, and modified the autoload.php to auto-load it.
After that I can access it in other controllers through composition like:
$this->someclass->some_function();
But still I cannot sub-class it like:
class SubClass extends Someclass {
// some logic here
}

Yeah, I had wanted to do the same at one point and was only able to pull it off when I hardcoded the include.
