Username field -- again

[BrentonEccles]

Umm, how do I prevent a user from having a number as the start of their username when registering?

Eg: stopping someone from registering with "1okayyeah" as their username? And getting an error message which tells them they need to have a letter at the start of their username.

Thanks for your help.

Try something like this:

$username = "1okayyeah";
if (preg_match("/^[0-9]/",$username))
	echo "Invalid username";
