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.
In case anyone wanted to see my current, semi-working example, here
ya go:
<?php
require_once 'ApplicationController.php';
require_once 'Zend/Form.php';
require_once 'Zend/Session/Namespace.php';
class IndexController extends ApplicationController
{
public function siteInformationAction()
{
$subform = $this->_getForm()->getSubForm('site_information');
if ($this->getRequest()->isPost() && $subform->isValid($this-
>getRequest()->getPost())) {
$subform->persistData();
return $this->getHelper('redirector')->gotoRoute(
array(
'action' => 'personalInformation'
)
);
}
$this->view->form = $subform;
$this->render('form');
}
public function personalInformationAction()
{
$subform = $this->_getForm()-
>getSubForm('personal_information');
if ($this->getRequest()->isPost() && $subform->isValid($this-
>getRequest()->getPost())) {
$subform->persistData();
$this->_getForm()->process();
exit;
}
$this->view->form = $subform;
$this->render('form');
