Forms have been an integral part of any interactive site since the dawn of time — they promote interactivity and are usually the most common way users interact with a site. It's commonplace that when a form is submitted (input), the website will take 'action' and do something with the data (processing) and then provide a user with the result (output). Symphony provides this logic layer via events.

This tutorial assumes you have a basic understanding of how events work in Symphony (if not, this may be a good introduction) and are semi-comfortable writing some PHP code. I'll be showing you some of the lesser-known features of Symphony events, including event priority, event chaining, and a brief demonstration of how to write a custom event. The difficulty level progresses as we go through, but with any luck you'll be able to learn a thing or two :)
