FormProcessor code updated

I’ve uploaded a newer version of the “FormProcessor”:http://peter.mapledesign.co.uk/quests/formprocessor.

h3. Changes

* Added support for radio buttons, checkboxes and selects.
* Maybe a few other things I’ve forgotten
h3. Current todo list:

# Write a rule extractor to work from an XML file
# Make it work with select fields with the @multiple@ attribute. This is rather important for me, as one of my projects uses a few of these fields. So what are the current problems? Well
## The code always expects a string rather than an array of fields
## Because the @select@ has to have the name @whatever[]@ when the XML parser goes through the XHTML form looking for fields named @whatever@ that match the contents of the array @$_POST['whatever']@ it doesn’t find any. So the selection does not get remembered, and the field cannot be validated.
# Convert the code to use HTML_SAX - a more liberal parser
# Allow the class to work with forms embedded in a XHTML page, and select which form to work on when more than one form is present in the page.

h3. Features I’d like to add:

* If you have a group of radio buttons inside a @fieldset@, I’d like to be able to add the .invalid class to the fieldset tag rather than the radio buttons.

And a couple of links from “Sitepoint Forums”:http://www.sitepointforums.com on form validation

* “Form Validation (cont.) “:http://www.sitepointforums.com/showthread.php?threadid=121129
* “Form Validation”:http://www.sitepointforums.com/showthread.php?threadid=77563 - with code from Vincent Oostind, but I think his approach is overkill
* “Advanced Form Validation”:http://www.sitepointforums.com/showthread.php?threadid=114185 - A thread by Simon Willison on his FormProcessor class, discussing the best way to handle validation.

On a related note, I stumbled across “dbForm”:http://dbform.sourceforge.net/ today, which is similar to PHPLens (but I think more basic) and of course free. I think it’ll find its way into my latest project…
