For remote validation, please show a code of check-email.php. I did not find any example. My code:
$email=$_POST['email']; $existing_mails=array('ma...@example.com','ma...@example.com'); if (in_array($email, $existing_mails)) { echo false; } else { echo true; } does not work. Can you please show just small example of php code you wrote for the demo mentioned here http://docs.jquery.com/Plugins/Validation/Methods/remote#options
