Ok, I have MY_Controller but now I want to create Front_End_Controller - El Forum - 09-01-2009

I've created MY_Controller inside of Application/Libraries and now I want to create a front end controller that extends off MY_Controller. This will be used by any controller that outputs HTML. I did some searching but didn't find any info on where to place that front end controller file and how CI will handle my extending off that controller.

I guess I have a related question, do you see this is as needed. I have a lot of code in my MY_Controller that has to do with prepping views and outputting HTML however not all my controllers would output HTML. Take a look:

Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/**
* MY_Controller
*
* Consider this the application controller.
*
* @package Firestarter
* @subpackage Core Extension

/*

    NOTE: Using this controller will change how you are using views.
    You will need to load a view in to a variable called $this->views['content']

    class MY_Controller extends Controller
    {

        protected $assests;
        protected $views;

            /* ---- Stylesheets ----
            
                In order to include a stylesheet on to the page, you must define it in the $this->assests['css'] variable.
                
                By default, you will set just a single string. You can set an array if you need to set options like media type.

                    $this->assests['css'][] = array('print', media="print");

heheh not willing to look through all the code to evaluate it, but you should be able to make "MY_FEC.php" and put it in application/libraries/

and for code do the same as before:

Code:
&lt;?php

class MY_FEC extends MY_Controller {

    function MY_FEC(){
        parent::MY_Controller();
    }

    function something(){
        echo "i *should* be accessible";
    }
}

and in the controllers that use the front end controller you will have:

Code:
&lt;?php
class thatonepage extends MY_FEC{
    function thatonepage(){
        parent::MY_FEC();
    }

    function index(){
        parent::something();
        $this->something();
        echo "I should work";
    }
}

note that MY_FEC was arbitrary...

That did not work. My front controller couldn't be found, which means I could include it manually but is that the only way to do it? Is there a way to do this natively within CI?

Interesting... I thought this would work, I'm surprised that once the base Controller is extended it wouldn't allow further extending...

anyways, sit back and relax, someone else will have the correct answer.

I had this problem before you only have one of the following options:
1. put all classes that you extend from Controller in MY_controller.php
2. put them in their own file and do include inside MY_controller.php

These are the only solutions at this point.

worst come to worse look up HMVC and matchbox
