Nothing stops you from presenting the form and process it with the same
script.

You may want to take a look at this forms generation and validation
class that shows you how to do that. Additionally it generates your
forms with Javascript to validate the form also on the client site,
avoiding unnecessary server round trips just to tell the user the form
has invalid fields.
