I'm writing a web form to accept user applications. Like most programs,
I'd like to keep the garbage characters out to limit hacking attempts.
I want to verify the firstname and last name fall within some guidelines.
I realize there is a wealth of exceptions, but this program is designed to
be used largely by my family. That isn't to say that others on the net
will try and hack it. I was wondering if anyone could help me come up
with a good regular expression to allow only letters, spaces, and
apostrophes (e.g. O'Donnell, Van Linden would be valid). I'm not quite
clear on how to do exceptions.
Ex: if ($st contains anything other than [a-zA-Z\s\']) {
&Error("Stick with letters, spaces, and apostrophes please.");
return 0;
}
Thanks.
