Zebra_Form
A jQuery augmented PHP library for creating and validating HTML forms
...Has an integrated cross-site scripting prevention mechanism that automatically strips out potentially malicious code from the submitted data. It also prevents automated SPAM posts, out of the box and without relying on CAPTCHA by using honey pots.
Output can be generated either automatically or manually through templates (basic PHP files). When generated automatically, the generated output validates as HTML 4.01 Strict/XHTML 1.0 Strict/HTML5 and has the same look & feel across all major browsers like Firefox, Chrome, Opera, Safari, Internet Explorer 6+.
