Controller within Controller Issue

Hey,

In CodeIgniter 2.2.0 I was able to create a Controller object inside a Controller. In CodeIgniter 3.0.0-develop I am no longer able to do this because I get the error message: "Unable to locate the specified class: Session.php". Am I missing something? Here is my setup.

1) autoloader.php:

PHP Code:

$autoload['drivers'] = array(
    'session'
); 


2) config.php:

PHP Code:

$config['sess_driver']            = 'native';
$config['sess_valid_drivers']    = array();
$config['sess_cookie_name']        = 'bbp_user_sessions'; // Custom class.
$config['sess_expiration']        = 21600;               // 6 hours
$config['sess_expire_on_close']    = FALSE;
$config['sess_encrypt_cookie']    = TRUE;                // Use security
$config['sess_use_database']    = TRUE;                // Use database
$config['sess_table_name']        = 'bbp_user_sessions';
$config['sess_match_ip']        = FALSE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']    = 300; 


3) bbp_user_sessions table

Code:

CREATE TABLE `bbp_user_sessions` (
 `session_id` varchar(40) NOT NULL DEFAULT '0',
 `ip_address` varchar(45) NOT NULL DEFAULT '0',
 `user_agent` varchar(120) NOT NULL,
 `last_activity` int(10) unsigned NOT NULL DEFAULT '0',
 `user_data` text NOT NULL,
 PRIMARY KEY (`session_id`),
 KEY `last_activity_idx` (`last_activity`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Can you post your controller example too.

Can you post your controller example too.

My example is too complex, so I replicated the very same problem using the CodeIgniter-Develop base.

Step 1) Download 'CodeIgniter-Develop'

Step 2) Update  autoloader.php & config.php & bbp_user_sessions table so it looks like my initial post.

Step 3) Don't forget to set the encryption key in config.php too. I used:

PHP Code:

$config['encryption_key'] = 'Gargantia on the Verdurous Planet'; 


Step 4) Modify the 'Welcome.php' file that comes already with the framework to look like this:

PHP Code:

class Welcome extends CI_Controller {

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Home extends CI_Controller {

    /**

     * map to /index.php/welcome/<method_name>
     * @see http://codeigniter.com/user_guide/general/urls.html
     */
    public function index()
    {
        echo "Testing: Home Page";
        
        $this->load->view('welcome_message');
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/Welcome.php */ 


Step 6) Load up webapp through your Nginx/Apache/Lighttpd/etc and you'll see the same error message.

I see .. the problem is, that the session is loaded twice .. for the main controller and also from the included controller.
Right now i have no idea how to solve this.

I logged a ticket for this issue: https://github.com/bcit-ci/CodeIgniter/issues/3480

you can't call a controller inside another controller. this is not hmvc (or whatever the name is...)

In CodeIgniter 2.2.0 I was able to create a Controller object inside a Controller.

Yeah, don't do that. It's a really bad anti-pattern for a framework like CodeIgniter.

Instead, you may want to move the relevant code in the "recipient controller" into a model instead. There is a one-to-one relationship between an HTTP request and a controller, but a one-to-many between controllers and models.

This may change in future versions, but for 2.2 and 3.0-develop as currently implemented, that's how it is.

Hi I am working with Hideauze on this project. I understand where you are coming from, it's just that it worked in 2.2 and we really want to take advantage of what 3.0 has to offer.

It looks like we've overcome most of these issues - the last thing we are having a problem with is wide Ajax calls.

We could leave our project in 2.2, but from a security and overall standpoint I'd really like to see this in 3.0.

I realize that HMVC isn't supported, but we've gotten it so close, that I'm wondering if any insights can be provided.

If anyone wants to take a stab at this, I'm glad to share some code.

You can always post in the "General Help" forum, just be more specific about it.

Check this replacement for the Session driver and tell me if it works for you:
