Zend_Form is a library that comes with Zend Framework, so if you have any questions or contribution (new ideas) on how to best implement this library feel free to post your comments

I have a few questions. Does it allow for sticky forms? By sticky, I mean that when you fill out a form and the information you entered doesn't pass all the validation checks, do you have to retype your info or does it remember it? Does it allow you to define custom error messages for validation checks? Where do the error messages appear- above the entire form or above each respective input element? Does it have AJAX capability or hooks for JavaScript validation?

I like its functionality, but found it too reliant on other pieces of ZF. The decorators are also very poorly documented.

For other projects, I still use my own form classes because of this.
