Looking a PHP library for creating and validating forms

I work with my own homemade framework and I want a library (classes) PHP 5 for generating form with validation and if possible with support ajax support HTML5.

I already did a search and found PFBC (PHP Form Builder Class) and HTML_QuickForm but it is obsolete.

Do you know of others?

I await your opinion.

Thank you

 

Some frameworks have this built in. You might try to borrow some of that code from Yii, for example.
