New to Codeigniter Error issue with Login and Register code

Hi

Very new to Codeigniter 

when using the Login and Register Video part 6 I keep coming up with this error, when xss_clean is taken out of the code as advised.

A PHP Error was encountered

Line: 292
Function: require_once


Fatal error: Call to a member function where() on a non-object in C:\wamp\www\ci_user\application\models\model_users.php on line 7

Yes I did extend the CI 
The problem seems to be in the file below with the callback function :

Maiin.php

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');


class Main extends CI_Controller {


public function index(){
$this->login();
}

public function login(){ 
$this->load->view('login');
}

public function members(){
$this->load->view('members');

}

public function login_validation(){

$this->load->library('form_validation');

$this->form_validation->set_rules('email', 'Email','required|trim|callback_validate_credentials'); 
$this->form_validation->set_rules('password', 'Password','required|trim');  



if ($this->form_validation->run()){
redirect('main/members');
}else{
$this->load->view('login');
}
}

public function validate_credentials (){
$this->load->model('model_users');

if ($this->model_users->can_log_in()){
return true;


}else{

$this->form_validation->set_message('validate_credentials','incorrect username/password.');

return false;
}


}

}

It sounds like your database driver is not being loaded ... $this->load->library('database'); or autoload it.
Further, your class name may work on WIndows, but you will have issues with the non-UCfirst name if you deploy to a Linux server; the class name should be Model_users.

Thanks for your help the problem was in $autoload['libraries'] = array('database', 'email', 'session');
the array was not loaded with information.
Now working fine  thanks

I bet us newbies keep you busy with crazy questions??
