PHP-Form Framwork help

I am working on a form framework that uses AJAX, and PHP OOP which are two things i am fairly new too.

Instead of making it myself, and crossing my fingers I was wondering if ya'll could give any comments at all about it so far? I would like to know if i'm going in the right direction.

The basic idea is to make writing forms easier, and to have 'standard' forms pre-made.
I'm sure their is something like this already, but I wanted to see if I could code this myself.

You can find everything here:

Their is a page that shows, the code and the functions.
You can also test what I have.

As of now it just displays a form, and allows users to input data.
The submit button does not work yet.

Thanks so much for the help!
