He should do like a live stream on one of these. That way if someone notices and error, we can tell him right away haha! Awesome tutorial as always though! :D

I would do the form validation on client side with javascript and validate it on server side as well, since you can give the errors on runtime with javascript. Server side validation is mandatory if the user removes the javascript validation.

[TheRoxasth]

Check your form. The cause of the problem maybe come from the typo of the name element in the form tag.

You forgot ")" after $_POST['username'] at 7.16

[KalenKubik]

To check for spaces, remove the "=== true" from the if statement.
"if (preg_match("/\\s/", $_POST['username']))"

[TheRoxasth]

As i know, "/\\s/" match only if the string has '\' and 's' character in a row. It doesn't not match the whitespace. How it is return true then? Anyone can explain it to me?

[MoRamzan]

why use if(empty($errors) === true) rather than if(empty($errors)) ???

[mikeeskenasy]

getting an error on print_r($errors);   Anyone have any idea why?
