Weel, since this is a PHP list I will assume you are checking once the
page is posted/submitted...
off the top of my head, the functions strlen() and isset() come to mind.

I have a form with various fields on it that I want to make sure
aren't empty or the user didn't just hit the space bar or return (in a

on a textarea if the user simply hits a space or return and submits
the form.
