A little homework
The other day I got asked to do a little smart form for product pricing for a print shop. Three dropdowns, plus a label showing the price based on the selection.
First I thought I would do it in PHP with HTTP Post. Then I thought I would do it with PHP and AJAX. Then I thought I could just do it all in DHTML/AJAX. Then I thought I could just to it in Flex. (In the middle there I did consider doing it with Flex and PHP.)
Anyway, doing it with Flex was quick and ... nice.
