Passing vars from MY_Controller to child controllers and views

[eluser]suntrop[/eluser]
Hi there.

I want to have some variables from a config table in my DB. Since I need them everywhere I'm loading them in MY_Controller. But somewhere between the controller and the view they get lost. print_r writes blank array to my screen.

MY_Controller.php [EDIT: code is in constructor]

Code:

$this->load->model('global_model');
$config_db = $this->global_model->get_config_db();

global_model.php

Code:

function get_config_db()
    {
        $query = $this->db->get('config');
        return $query->result_array();
    }

Welcome Controller (welcome controller extends public controller which extends MY_controller)

Code:

$data['app_config'] = $this->config_db;  // this should come from MY_controller
$data['content'] = 'welcome';
$this->load->view('includes/template_public', $data);

... and in my view:
<pre>&lt;?php print_r($app_config); ?&gt;</pre>

But all I see is
Array
(
)

How do I access the vars from the MY_Controller in a subset controller?

Hope someone can please help.

Code:

class MY_Controller extends Controller
{
public $config_db;

function __construct()
{
   parent::__construct();
   $this->load->model('global_model');
   $config_db = $this->global_model->get_config_db();
}

Thanks, but there is no effect at all.

If I don't declare a variable, it is the same as public, isn't it? I am just starting to write OOP.

Code:

class MY_Controller extends Controller {

    function __construct() {
        parent::__construct();
        $this->load->model('global_model');
        $this->config_db = $this->global_model->get_config_db();
    }

}

In PHP, yes... If you don't declare class members as otherwise they are public.

:-)

That's it …
$this->config_db = $this->global_model->get_config_db();

Thanks a lot!
