PHP form generation and validation standalone class

Question

Hi all,

I am looking for a form class that:

1. Is standalone/doesnt need a framework to run
2. Has easily configurable validation
3. Has validation and generation for all form fields including checkboxes(one solution I found was great except it didnt have any check box functionality)

I have had a look on google and stackoverflow but most everything I found was a year old, I am hoping in the last year something has been developed or improved.

My reason for asking is that I have a couple of very large forms to make that without a form class are going to take ages to build. Unfortunatly I dont have time to develop my own class but I do have time to learn and use a recommended one as undoubtedly it will be far faster than writing hardcoded html forms with a PHP validation script.

I hope someone can help Regards Luke

UPDATE:

Phorms has been fantastic, very simple to use syntax and very easy to bring into a project, the ability to set data for the form is great and also very simple to use, so great for a cms needing to edit articles etc.

Answer 1

Phorms comes to mind, and it's lightweight.

The author of PHPClasses.org also has a very complete, altough somewhat blowated library.
