it seems to be a big problem for me doing this all night,

first im not able to get the first_name from my database

in my members_model:

Code:
function validate()

 {

  $this->db->select('first_name');

  $this->db->where('email', $this->input->post('email'));

  $this->db->where('password', md5($this->input->post('password')));

  $query = $this->db->get('registration');

  if($query->num_rows == 1)

  {

   return TRUE;

  }

 }

i can't find a way to make this right

please guide me tnx
Thanks for reply
