</html>it exactly no error, but when i load the page(the submit button is not even click) the password error has been displayed. other field error work just fine.
Your password block is outside of the POST block and that is why the
$passwordErris always set even before the form is submitted.Put it inside the block
if ($_SERVER["REQUEST_METHOD"] == "POST") {Also in your code
$nameErr = "Special characters are not allowed";is wrong. You must assign the error to $passwordErr like I have done in the code above.
