Which php module handles the events after Submit is clicked?

I would like to add a process at the point Submit goes to the notification phase or least past any possibility the Submit may have failed for input error reasons.

I've done a few on the formcontroller.cls.php

Thanks, that certainly looks like a good place to do it.

Have you ever had to deal with form field values being available in this module?

My plan is to update a column in an existing database to indicate the user has had his new license generated, so then he won't be able to use the form to regenerate more licenses. I just need one of my values available to do the lookup and insert.

I would use the $_SESSION variables. Their already available.
