Question

I have created a MY_Controller class to check for sessions.

My LoginController is checking the user information and if that is ok, I redirect the user to the PainelController. I use redirect so my url will be refresh with /localhost/painel instead of /localhost/session/login

The problem is that when I use redirect, I cannot access my session, only using load->view.

Is there a workaround?

Thanks in advance for any help.

PS: I use a .htaccess, the one found on CI Wiki

EDIT

class MY_Controller extends CI_Controller {

    public function __construct() {
        parent::__construct();
        if(!$this->session->userdata('usuario')) {
            redirect('login');
        }
    }

}

Piece of Login: extends CI_Controller

if( $rs )
            {

                $this->session->set_userdata('usuario', $usuario);//usuario is a object
                //$this->load->view('painel');//it works
                redirect('painel', 'location');//it doesn't
            }
            else
            {
                $this->load->view('login', $data = array('mensagem'=>'Usuário ou senha inválidos.'));
            }

My Painel View

echo $this->session->userdata('usuario')->usuario_nome; //it works
only if I load->view('painel')

Even if I try to access this session value on my PainelController (extends MY_Controller) it won’t work, will say:

Message: main() [function.main]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Usuario" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition

I tried redirecting a couple of times on my CI sandbox but I didn’t lose my session.
What libraries/helpers are you using in PainelController?
It seems you don’t have @session_start(); in that particular controller.

Usually, you can use existing Auth libraries that will handle this for you, and then include this in the constructor of every controller that or even in MY_Controller.
Here’s an example:

class Events extends CI_Controller {
// Constructor function
public function __construct()
{
    //load initial models and libraries that are needed for the controller
    parent::__construct();
    $this->load->library('auth');
            ...
    }
    ...
}

And then my auth library would have a constructor like this.

class Auth {
  var $CI       = NULL;

  function Auth($props = array())
  {
    $this->CI =& get_instance();

    // Load additional libraries, helpers, etc.
    $this->CI->load->library('session');
    $this->CI->load->database();
    $this->CI->load->helper('url');
    @session_start();
  }
  ...
}

EDIT:

You can also include this in your autoload usually located at config/autoload.php.
http://codeigniter.com/user_guide/general/autoloader.html

Here’s an example.

/*
| -------------------------------------------------------------------
|  Auto-load Libraries
| -------------------------------------------------------------------
| These are the classes located in the system/libraries folder
| or in your application/libraries folder.
|
| Prototype:
|
|   $autoload['libraries'] = array('database', 'session', 'xmlrpc');
*/

$autoload['libraries'] = array('database','session', 'encrypt');
