Form and SQL generator, CSS compatible: This class will do a couple of things for you.

This class will do a couple of things for you. It'll give you an easy way to generate forms, and when the form is submitted, it'll also generate the SQL to store the values the user entered in the form. It'll also generate CSS identifiers for each form element, so you can use CSS to position the stuff.
There's also a formextra.inc class, which'll allow you to add my custom made multiple selectboxes
