dfowler Posted January 31, 2008 Share Posted January 31, 2008 Hey guys, I have recently created my first members section for a web site. How do I set it up so that a user's username can't contain any space, or special characters, and be a minimum of 5 letters? I'm sure this is something not too difficult, but I've never had to do it and I'm not sure how to do this. Thanks for any help!

dfowler Posted January 31, 2008 Author Share Posted January 31, 2008 I ended up using !ctype_alnum($user1) to get rid of the special characters. Thanks for the help.
