Re: [fw-general] Zend_Form multipage examples?
Hi Justin
On top of what you have here for persisting data from form submission,
the helper proposal allows you to specify the order in which forms are
processed. So you can prevent someone from jumping straight to the
'personal' action if the 'siteinformation' form has not yet been
validated.
That, and it also interacts with the redirector to allow you to
specify a destination action using the key names of form submit
elements (_next, _back, _submit, etc..) if you're operating a 'wizard'-
style or even tabbed-style interface.
Cheers
You'll probably want to store the data from validating the subform in
your session so you can retrieve it later; otherwise, your data will
be
lost. There's a variety of ways to do that -- using $_SESSION
directly,
or using Zend_Session -- so I won't go into details.
I just found the persistData(), thought it doesn't appear to be used
anywhere. I did some more hacking and added Zend_Session_Namespace
into the mix. I'll check out the Helper proposal to see if I'm
missing anything.

ya go:
_getForm()->getSubForm('site_information');
if ($this->getRequest()->isPost() && $subform->isValid($this-
>getRequest()->getPost())) {
$subform->persistData();

I'm aware of that; I haven't had a chance to work up more advanced use
cases and examples for this bit of functionality yet.
