Cookie/Session value gets destroyed after redirect. Help please :(

[eluser]debasishdebs[/eluser]
Cookie aint available till next server request? Means till i redirect to "dashboard" controller i cant access it right? But it doesnt redirect.

&
$this->access->login() is function from access.php application->library. Inside it i have set 'group_id' inside session varible so it should return something and not null.
M giving up code for login()

Code:

function login($username, $password)
{
  $result = $this->users_model->get_login_info($username);

  if ($result) // Result Found
  {  
   if (empty($result->active))
   {
    return 'BANNED';
   }
  
   if (!empty($result->verifystring))
   {
    return 'NOT_ACTIVATED';
   }
  

   $password = md5( $password); // Hash input password

   if ($password === $result->password) // Passwords match?
   {
    $this->CI->session->set_userdata(array('id'=> $result->user_id, 'group_id'=> $result->FK_group_id));

    return TRUE;
   }

  }
  
  return FALSE;
}
