Re: Stumped by regex

Does it _need_ to be one regex? You might be better of checking the length first? Something like this...?

UPDATE: See replies....

if (length($name) <= 20 and $name =~ m/^\w+\s(\w+\s)?\w+$/i) {
    print "okay\n";
}

By the way, your character restriction doesn't work because you can match up to three characters in one go within the parentheses, so your upper limit here is actually 60.

yup, dumb mistake by me. Also though, I assumed there was a first name here too. So the above regex allows an additional space that it shouldn't. You're probably okay with just the following... `$name =~ m/^[a-z]+\s?[a-z]+$/i` [download] ...although this does force a minimum length of 2. Having said this, if I'd seen JediWizard's reply, I wouldn't have posted mine. I think he nailed it first time (++). --- my name's not Keith, and I'm not reasonable.	[reply] [d/l]

You might even prefer `[[:alpha:]]+` instead of hard coding a-z in case you ever need to work in non-ASCII-betic locales.</pedant>	[reply] [d/l]
