Load controller from another controller

#1
Hello,
I was wondering if it's possible to load a controller through another controller. As i've searched the internet i found some articles that people mentioned that this is "not a working practice for MVC pattern".

The reason i want to achieve such a thing is for situations like:
e.g.: Let's say i want to get something from the db and place in header or footer (analytics scripts, footer copyrights text etc..) and in order to have cleaner "view" files i want to create some controllers (sth like "common/header", "common/footer" etc.) and be able to load them in the other controllers.

Any ideas / suggestions on that? 

Thanks

Did you think of using a library for that? Or create a MY_Controller.php in the application/core folder. Write a method to generate a common set of views or even different sets of views.
Let all your controllers (which are classes) extend the MY_Controller's class. Like that, you can use "common" methods in all your controllers.

If you use the HMVC it allows controllers to load other controllers.

I've tried this method and yeas it works! But i see a lot of people suggest not to do such thing like extending controllers in core folder. That's why i thought to ask for an alternative (in case there is one)!

I've seen it and i'll use it as it looks like, but i was wondering if there was any other alternatives! Thanks though for pointing the right direction!

These people are probably trying to keep you away from modifying the system/core files. But the application/core folder isn't forbidden ground if you want to use a MY_Controller or MY_Model etc.

WiredDesigns needs to be patched to work with current codeigniter installs. This is the skeleton I created for myself that I use:

https://github.com/mladoux/ci-skeleton

It has HVMC and a custom autoloader mod so you can name your controller extensions whatever you want ( not just MY_Controller ).

You can do that (but I think library and real MY_controller are better):
I Have a directory 'application/font_controller' with a file called Font
Front.php

PHP Code:
<?php
//$object is the oject of my controller
class Front {

 
   public function __construct() {
 
       //Do what you want
 
   }
 
   
    public 
function footer($object) {
 
       $object->load->view('template/footer',$object->data);
 
   }
 
   
    public 
function header($object) {
 
       $object->data['header'] = 'My header';
 
       $object->load->view('template/header',$object->data);
 
   }
 
   
    public 
function page($object) {
        
//Example: you can load everything with $object
        
$object->load->helper('url_helper');
 
       $this->header($object);
 
       $this->footer($object);
 
   }

My controller

PHP Code:
include_once (__DIR__.'/../Front_controller/Front.php');

class 
Com extends CI_Controller {
 
   public $data;
 
   
    public 
function __construct() {
 
       parent::__construct();
 
   }
 
   
    public 
function index() {
 
       $this->data['footer'] = 'My footer';
 
       $front = new Front();
 
       $front->page($this);
 
   }

The correct way to do this is to have a global Model being loaded by autoload, and there you create a function that will perform the insertion of your header and footer, you can also send a parameter and use as embedding views.

public function loadLayout($view = null, $data) {
//Load your data here

$this->load->view('header', $data);
$this->load->view($view, $data);
$this->load->view('footer', $data);
}

Use a library or a model.
