CSS-Tricks #50: Building a Customized and Dynamic Ordering Form
Real-life clients have real-life needs for their websites. They don’t care about your fancy RSS feeds and AJAX, they just want their website to do what they tell you they want it to do. In this screencast I walk through an example feature I am building for a real-life client who needed some very specific functionality built into a page. It is an ordering process that needs to check for a valid zip code, and then do a bunch of custom calculations based on quantities, shipping costs, etc. Both jQuery and PHP are used to do the heavy lifting.
