Library creation problem!

Thank you again.


I tried that way but it doesn't work. But I tried another method as you mentioned and that works fine. Now the library is like this:

Code:

class User_authentication
{

    function User_authentication()
    {
        $this->obj =& get_instance();
    }

    function display()
    {

        // Not logged in, then redirect to the Home Page.
        if(!$this->obj->session->userdata('logged_in'))
            redirect('', 'refresh');        
    }

}
