Did you load the Session Class in autoload.php or your controller?

Also next time please use code tags to wrap your code!

@InsiteFX


i did autoload the Session Class


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

[eluser]InsiteFX[/eluser]
And where are you setting the session variable?

InsiteFX

[eluser]oukarai[/eluser]
in my login.php's validate_credentials action

Code:

function validate_credentials()
    {        
        $this->load->model('membership_model');
        
        $query = $this->membership_model->validate();

        if($query) { // if the user's credentials validated...
        
            $data = array(
                'username' => $this->input->post('username'),
                'is_logged_in' => true
            );
            
            $this->session->set_userdata($data);
            
            redirect('site/members_area');
            
        } else { // incorrect username or password
            
            $this->index();
            
        }
    }

Did you download the newest HMVC from the CodeIgniter WIKI?

That Example is for the older CodeIgniter v1.7.3

CodeIgniter 2.0.+ uses PHP 5+ so you need the new HMVC for it to work.

InsiteFX

[eluser]oukarai[/eluser]
yes i did

That Example is for the older CodeIgniter v1.7.3
but i didnt find the codeigniter-modular-extensions-hmvc 5.2

so i go to Modular Extensions - HMVC

the site above and got the most newest hmvc file

by the way , i use ci 2.0.1 now and php 5.3
