I have created many Yii applications successfully but recently I have started having problems with login in Yii applications.
The issue appears casually once people try to log in with Mozilla Firefox browser, the log in succeeds with no error messages and user id is stored to: Yii::app()->user-id, but after redirection, everything is gone. In many cases cleaning the browser data solves the problem but I think there should be a better solution. This "bug" does not only appear with Yii applications but my partners keep telling about the problem in few other platforms too.
I have tried to debug the problem but I haven’t got any good ideas yet. It just seams that cache memory get confused or messed up. Have anyone else faced this problem?
My login form and useridentity code:
//THIS IS THE LOGIN FUNCTION THAT IS CALLED IN CONTROLLER.
public function login()
{
if($this->_identity===null)
{
$this->_identity=new UserIdentity($this->username,$this->password);
$this->_identity->authenticate();
}
if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
{
Yii::app()->user->login($this->_identity);
echo Yii::app()->user->id; //debug row, returns an integer
die(); //debug row
return true;
}
else
return false;
}
...........
class UserIdentity extends CUserIdentity
{
private $_id;
//THIS IS CALLED BY LOGIN FORM
public function authenticate()
{
$record=User::model()->findByAttributes(array('username'=>$this->username));
//var_dump(md5($this->password));
if($record===null)
$this->errorCode=self::ERROR_USERNAME_INVALID;
else if($record->password!==md5($this->password."SALT"))
$this->errorCode=self::ERROR_PASSWORD_INVALID;
else
{
$this->_id=$record->id_user;
$this->errorCode=self::ERROR_NONE;
}
return !$this->errorCode;
}
public function getId()
{
return $this->_id;
}
}
So, once I have debug rows uncommented, the result is a real integer(an user id), it tries to say login worked I guess. Once debug rows are removed and redirecting is done, the user id is gone too. No session is stored.
And the problem appears casually, I haven’t been able to track all the factors which causes the problem but it really happens casually in many different computers, in different operating systems and at least in Firefox browser.
Thanks in advance if someone could give me any hint…
