I'm not 100% sure but I think what you need to do is create 2 forms,
one for 'back' and the other for 'next. The 2nd one is this page's
form, as normal. The 'back' one, though, consists only of hidden
inputs with the values submitted from the previous step. Meaning,
you'll need to set() some view vars of the latest submitted data for
each next view. It might be easier in this case to not use FormHelper
for the 'back' form and instead use regualr HTML. Just ensure that you
name the elements correctly, ie name="data['model']['field']" value="<?
= $some_var ?>"
Obviously, you'll need to also ensure you're not saving data twice.
So, instead of only doing if(empty($this->data)) you might do
something like:
if (empty($this->data) && !isset($this->data['ModelName']['id']))
{
/// save the data and redirect to next step
}
// show the form
Or something like that. I know there was a Wizard component or helper
or somesuch at the Bakery a long time ago. You might want to have a
look at that for ideas.
