A HTML_QuickForm SubForm element type

I've created a "subForm" element type for HTML_QuickForm which takes any HTML_QuickForm and makes it an element in another form. http://fb.reversefold.com/SubForm.phps A few caveats: this element *must* be either created by a call to addElement on your main form (with the construction parameters, not an element object) or you must call setParentForm on the element. If you don't, the rules on the subform won't work. Here's the two usages (assuming $form is the main form and $subForm is the sub-form): require_once('HTML/QuickForm/SubForm.php'); $form->addElement('subForm', 'subFormElementName', 'Sub Form Label', $subForm); //NOTE: with this version $subForm is now a copy in the element so changing // $subForm now will not change the form within the element OR require_once('HTML/QuickForm/SubForm.php'); $el =& HTML_QuickForm::createElement('subFormElementName', 'Sub Form Label', $subForm); $el->setParentForm($form); $form->addElement($el); This also uses a few hacks which access HTML_QuickForm internals which is a no-no, but it's the only way I could get unfreeze and setPersistentFreeze to work as HTML_QuickForm doesn't implement these functions (perhaps these should be added?). This *should* work with any renderer, but I haven't tested it and I modeled it on the default renderer, so it could quite easily not work with other renderers. However, it should work with customizations of the default renderer. This *should* also work for subforms within subforms. ;-) In fact, it does. http://fb.reversefold.com/SubFormTest.php If anyone uses this or has any ideas, please let me know. -- Justin Patrin
