Login System, help?

[eluser]Declan[/eluser]
I changed the validate_login() function to look like this:

Code:

function validate_login()
    {
        die('here');
        $this->load->model('membership_model');
        $query = $this->membership_model->validate();    
        
        if ($query)
        {
            $data['username']         = $this->input->post('username');
            $data['is_logged_in']     = true;            
            $this->session->set_userdata($data);
            
            redirect('navigate/online');
        }
        else
        {
            $this->index();
        }
        
        
    }

But still get a 404, I'm boggled.
