ComboValidation

ComboValidation is a class meant to validate HTML forms via PHP and JavaScript in the simplest possible way. All you need to do is to create an array of form fields' information with the required parameters and then call a few methods. It is customizable (validation and view), cross-browser (IE6+, Firefox2+, Opera7+, Safari3+, and all Mozilla based browsers), very well tested, easily integrated, lightweight, extensible, PHP 4 and 5 compatible, multi-lingual, and XHML valid, and has AJAX support.
