I find a bug into your class.login.php. if you use a development server and enabled the php errors and warnings you will get a undefined token error. Because in the constructor you define the token : $this->_token = $_POST['token']; So if your creating a new file and initialise the login class you will get the post error because it's not existing var... so what I did to fix this little bug is change the token definition to :

$this->_token = isset($_POST['token']);

@domentarion Thank you for the comment. I think you might have misunderstood what the POST variable token does. The POST token variable is a randomly generated value used to validate if a form submission is unique during the current session. Your code suggestion only checks if any token value has been submitted. You actually need to generate a unique value during the current session and then validate that it came from the same session.

[phpclass]

@domentarion $this->_token = isset($_POST['token']); actually gives you a TRUE or FALSE value. This is flawed because I can easily submit data from a form on another domain and your code will accept it. The code that I put for download didn't have any bugs when I tested it. So it should be fine. Let me know if you still have trouble. Thanks.

[phpclass]

@domentarion Try using this line of code

$this->_token = isset($_POST['token'])? $_POST['token'] : 0;
