Unifying Server-Side and Client-Side Input Validation + coding contest!

My new article in the May 2007 php|architect magazine is loads of fun!

Readers will learn how to create a central validation library to simultaneously handle both front and back-end input validation providing both security and instant user feedback. Along the way there will be plenty of exuberantly-joyous moments with regex, Json and PHP-powered JavaScript.

To add to the excitement, there is a coding contest at the end with a superb grand prize!

You cannot afford to miss this spectacular article!
