Cakephp auth is not working on production - cakephp

Question

Guys I uploaded my site on servers and I'm facing this problem.
Usercontroller.php
<?php
class UsersController extends AppController {
var $name = 'Users';
var $components = array('Auth', 'Acl');
function beforeFilter(){
//parent::beforeFilter();
$this->Auth->loginError = "asdad!";
$this->Auth->authError = "sdsd !.";
App::uses('CakeEmail', 'Network/Email');
$this->Auth->userModel = 'User';
$this->Auth->allow('login','register','login','step2','TakeId','kontakt');
}
function login(){
if(!empty($this->data)){
$this->request->data['User']['password'] = AuthComponent::password($this->request->data['User']['password']);
$sprawdz = $this->User->find('first',array('conditions'=>array('User.username'=>$this->request->data['User']['username'],'User.password'=>$this->request->data['User']['password'])));
echo debug($sprawdz);
if(!empty($sprawdz)){
if($this->Auth->login($this->request->data)){
$this->redirect('/');
echo debug('you are log in!') ;
}
}
else {
$this->User->invalidate('username', 'mistake!');
}
}
}
function logout(){
$this->Auth->logout();
$this->redirect('/');
}
}
User/login.ctp
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->Form->create('User'); ?>
<fieldset>
<?php echo $this->Form->input('username');
echo $this->Form->input('password'); ?>
</fieldset>
<?php echo $this->Form->end(__('Log in')); ?>
It is like Auth does not work at all. In localhost was fine. Additionaly, users/index is empty page :)
Any ideas would be great. Thanks.

Answer 1

Keep it simple, and follow the tutorial which shows how to use the auth component.
For example, try this:
function login(){
if ($this->request->is('post')) {
if ($this->Auth->login()) {
$this->Session->setFlash('You have successfully logged in the system');
return $this->redirect('/');
}
$this->Session->setFlash(__('Invalid username or password, try again [warning]'));
}
}
Also please make sure Security.Salt which is responsible to hash a password with the application's salt value
You did not defined any index function in usersController, that is why it is throwing error. Try to enable debug mode on so that you can track the errors

add $this->request->data on 2nd line of your login aciton-
function login(){
if(!empty($this->request->data)){
$this->request->data['User']['password'] = AuthComponent::password($this->request->data['User']['password']);
$sprawdz = $this->User->find('first',array('conditions'=>array('User.username'=>$this->request->data['User']['username'],'User.password'=>$this->request->data['User']['password'])));
echo debug($sprawdz);
if(!empty($sprawdz)){
if($this->Auth->login()){
$this->redirect('/');
echo debug('you are log in!') ;
}
}
else {
$this->Session->setFlash('Invalid username or password');
}
}
}
