BrainCMS - preg_match register username

[AlexstyleRetro]

Hi Devbest,

in my register.php it is not possible to register username with .,- or special characters. Only letters are allowed.

Which file should I change?

Thanks a lot to those who will help me

It'll be in the config somewhere for the BrainCMS engine, I could help you a lot more if it was RevCMS, I've never used Brain

In "/system/app/classes/class.user.php" replace the function validName with this one.

public static function validName($username)
{
    return preg_match('~^[a-z0-9.,-]{3,12}$~i', $username);
}

Username must be between 3 and 12 characters long and you should be allowed to use letters, numbers and these special chars: . , -
Didn't test it but should work.

Thanks for reply

Code now is

        public static function validName($username)
        {
            if(strlen($username) <= 12 && strlen($username) >= 3 && ctype_alnum($username))
            {
                return true;
            }
            return false;
        }

How should it become?
