Hi I want to check query result. If it's null I want to send data to DB. In my code even if result is null I can't update database.

    $this->db->where('login',$data_db['login']);      $query = $this->db->get('users');     if(is_null($query)) // If Login doesn't exist in DB     {       $this->db->insert('users', $data_db); // Insert into DB     } } 

I was trying to do that in other way but If user doesn't exist I got “Trying to get non object etc”

Other way:

$this->db->where('login',$data_db['login']); $query = $this->db->get('users'); $row = $query->row(); if($row->login)  {     $this->load->view('content/error');  } else {     $this->db->insert('users', $data_db); }
