can you guys tell me what's wrong ?.. the second error sounds familiar to me though

[trq]

The first error indicates that you are attempting to access an array index (called password) that does not exist. You should always check indexes exist before accessing them.

 

The second error is the most common of all errors. See the 'header errors' sticky at the top of this board.

fixed...I wrapped this block in a foreach loop

      if($result['password'] == $this->_password)
      {
        return TRUE;
      }

      if($query->num_rows() == 0)
      {
        $this->form_validation->set_message('password_check','There was an error!');
        return FALSE;
      }
    }

 

to

 

      foreach($result as $row){
      if($row['password'] == $this->_password)
      {
        return TRUE;
      }

      if($query->num_rows() == 0)
      {
        $this->form_validation->set_message('password_check','There was an error!');
        return FALSE;
      }
      }
