Autoload problem - El Forum - 05-11-2008

EDIT: Solved, see post #4 for info.

I put core session class to autoload, it works in a pre-controller hook, but calling it in the controller results in "Message: Undefined property: User::$session" and "Fatal error: Call to a member function userdata() on a non-object in /usr/local/www/casting/system/application/controllers/user.php on line 21".
Any ideas what might be causing it?
(and yes I'm a CI newb)
Below the code:
config.php
Code:
$autoload['libraries'] = array('database', 'session');hooks.php
Code:
$hook['pre_controller'][] = array(
'class' => 'Auth',
'function' => 'index',
'filename' => 'auth.php',
'filepath' => 'hooks',
);hooks/auth.php
Code:
class Auth extends Controller
{
function Auth()
{
parent::Controller();
}
function index()
{
$uri = $this->uri->uri_string();
//check versus recurrency
if($uri != '/user/login')
{
//id should be known
if(!$this->session->userdata('id'))
{
//save current uri to redirect back to it after login
$this->session->set_userdata('redirect' , $uri);
redirect('/user/login');
}
}
}
}controllers/user (constructor is blank apart from parent::Controller call)
Code:
function login()
{
$email = $this->input->post('email');
$password = $this->input->post('password');
if($email && $password)
{
$this->load->model('user_model', 'user');
if($auth = $this->user->auth(array('email' => $email, 'password' => $password)))
{
foreach($auth as $key => $value)
{
$this->session->set_userdata($key, $value);
}
if($redirect = $this->session->userdata('redirect'))
{
redirect($redirect);
}
else
{
redirect('');
}
}
}
$this->load->view('user/login');

Autoload occurs in the Controller constructor, and because you are using the pre-controller hook, autoload has not yet run.
get_instance() will also fail if the Controller is not instaniated yet.

Well, hook DOES work WITH preloaded stuff (uri, session classes and url helper) without problem, it's the controller that fails.

Basically, for some reason my User class, which extends Controller class appears to not have $this->session although the log says session has been initialized (and when I try to add another init it says that I am attempting to init it twice and the second instance is ignored).

Problem solved - CodeIgniter doesn't support extending Controller twice per request (or so does it seem) - I extended Controller with Auth and then tried to do the same with User - I ended up making the auth hook a function which worked post-controller and all conflicts were resolved.

[/quote]Hey Weedy,
Can you explain how you hooked a function to work post-controller? I am reading about hooks in the user-guide but it is a little confusing.
Thanks a bunch in advance

Yeah, what I did was made the hook a function (It could've been a class but since I can't have 2 controllers, it would be useless anyway):
Code:
<?
/**
* Auth
*
* Check if the user has been logged in. Uses Session class with DB sessions.
*
*
* @access public
*
*/
function auth()
{
$CI =& get_instance();
$CI->load->library('session');
$uri = $CI->uri->uri_string();
//check versus recurrency
if($uri != '/user/login')
{
//id should be known
if(!$CI->session->userdata('id'))
{
//save current uri to redirect back to it after login
$CI->session->set_userdata('redirect' , $uri);
redirect('/user/login');
}
else
{
$CI->load->model('user_model', 'user');
$CI->user->log(array('id' => $CI->session->userdata('id')));
}
}
}
?>This is loaded post controller:
Code:
$hook['post_controller'][] = array(
'class' => '',
'function' => 'auth',
'filename' => 'auth.php',
'filepath' => 'hooks',
);Uses user_model:
Code:
<?
class User_model extends Model {
function User_model()
{
// Call the Model constructor
parent::Model();
}
function auth($user)
{
$this->
db->
select('id, name, surname, email, company')->
from('_users')->
where('username = "' . $this->db->escape_str($user['username']) . '" AND password = MD5("' . $this->db->escape_str($user['password']) . '")');
$query = $this->db->get();
$result = $query->row();
if (!empty($result->id))
{
$this->log(array('id' => $result->id));
}
return $query->row();
}
function log($user)
{
if(!empty($user['id']))
{
//rework to use AR!
return $this->db->query('UPDATE _users SET `last` = "' . time() . '" WHERE `id` = ' . (int)$user['id']);
}
return false;
}
function insert($user)
{
return $this->db->insert('_users', $user);
}
function update($user)
{
return $this->db->update('_users', $user, array('id' => $user['id']));
}
}
?>And supplemented by User class:
Code:
<?php
class User extends Controller {
function User()
{
parent::Controller();
}
function index()
{
$this->login();
}
function login()
{
$user = $this->input->post('user');
$password = $this->input->post('password');
if($user && $password)
{
$this->load->model('user_model', 'user');
if($auth = $this->user->auth(array('username' => $user, 'password' => $password)))
{
foreach($auth as $key => $value)
{
$this->session->set_userdata($key, $value);
}
if($redirect = $this->session->userdata('redirect'))
{
if ($redirect == '/user/logout' || $redirect == '/user/')
{
$redirect = '/plan';
}
//move back to original request url
redirect($redirect);
}
//if no original request url, move to index
redirect('/plan');
}
}
$vars = array('title' => false);
$this->load->view('common/header',$vars);
$this->load->view('user/login');
$this->load->view('common/footer');
}
function logout()
{
$this->session->destroy();
redirect('');
}
}
?>Hope that helps.
