Sweet! That seems to work... What is the "^\d+$" doing exactly? I've
done a few searches and didn't come up with anything... where would its
use be documented?
It is a regular expression where
^
means the start of the string,
\d
means a decimal digit
\d+
means one or more digits and
$
means the end of the string.
The exact syntax of regular expressions differs from programming
language to programming language but most tutorials on regular
expressions should cover that.
