When to use parent::Controller(); ?

[eluser]Cro_Crx[/eluser]
You need to call the parent controllers constructor within your own controllers constructor, eg:

Code:

<?php

class Example extends Controller
{
    function Example()
    {
        parent::Controller();
    }

}

What this does is calls the CI_Controllers constructor before running any of the code in your constructor. This gives you the functionality of the Controller that you need, like the ability to load objects.

Without parent:Controller(); you wouldn't be able to run $this->load->xxxx; or anything else a Controller needs to do

You only need to call that line once. You don't need it in any of the functions except for the contructor.
