Help me to validate my RegEx code. - GoFuckYourself.com

Cyber Fucker · 01-21-2010, 10:55 AM

I want it to match all alphanumeric characters (digits and letters, uppercase and lowercase), spaces " ", underscores "_", dashes "-", and dots "." and it should be at least 3 characters long and not more than 32 characters long.

Would it be..

^[A-Z0-9.-_]{3,32}+$

^[A-Z0-9.-_]{3,32}$

^[A-Za-z0-9.-_]{3,32}+$

^[A-Za-z0-9\.\-_]{3,32}+$

Which one would be correct if any (I need it for vbulletin forms) ?
Thank you in advance for the help.

I think #4 is the closest. I don't think the minus sign is a metacharacter, so you don't need to escape it. I also don't think you need the plus sign before the dollar sign. Thus I end up with:

^[A-Za-z0-9\.-_]{3,32}$

Good luck

I don't know what you are talking about.

If the minus sign isn't a metacharacter, then what is it doing in eg A-Z and a-z and 0-9???

Of course it needs escaping

^[A-Za-z0-9\.\-_ ]{3,32}$

or shorter still
^[\w\.\-]{3,32}$
note with this though, \w as it's recognising word characters, will allow tabs and line breaks, not just white space.... if you don't want them, negate them:
^[\w\.\-^\t^\n]{3,32}$
