core/Lang.php

I'm trying to extend CI native Lang class to use MySQL Database. My problem is, i cant connect to DB or do $this->load->database or load anything.

I'v tried adding these classes manually like this:

Code:

# Extensions
require_once SYSDIR . '/core/Loader.php';
require_once SYSDIR . '/libraries/Session.php';

Still nothing. I also have Stackoverflows question running but it seems to have downgraded rating, like why? I'v been stuck on this for almost half a week and i cant figure it out.

Very short way to see my problem:

Code:

class JK_Lang extends CI_Lang {
       function __construct() {
        # Loading parent language class functions
        parent::__construct();
        
        # Loading database
        $this->load->database(); // Undefined property: JK_Lang::$load
        
        # Register as loaded
        log_message('debug', 'JK_Lang Class initialized');
    }
}

Fatal error: Call to a member function database() on a non-object in application/core/JK_Lang.php on line 31

PS: I'm very new to CI or any kind of MVC Framework.
