How do i insert into ci_session table, when user checks the checkbox ?

Right now i am using the following method to check if the user if logged in after the window is closed

Code:

if($query) // if the user's credentials validated...
   {
    $data = array(
     'username' => $this->input->post('username'),
     'is_logged_in' => true,
     'password' => $this->input->post(md5('password'))
    );
    $this->session->set_userdata($data);
    redirect('dashboard/members_area');
   }
