I have a PHP script that is supposed to check for "valid" human names, but recently cracked against a name with a space, so we added spaces to our validator.
Rather than doing this, is there a way to add a blacklist to CakePHP's validator to block all "invalid" characters, rather than allowing "valid" ones?

NOT: I (genellikle) PHP bunu nasıl biliyorum ama CakePHP'nin onaylayıcısı sözdizimi kullanarak farklı.
