[nycphp-talk] HTML_QuickForm_Controller question

Hello all,
I have been quiet for the last month (or two) because I have busy with
various things.
I have a question now, and I hope someone on the list will be able to help.
I have been using (the PEAR library) QuickForm (
http://pear.php.net/package-search.php?pkg_name=quickform&bool=AND&submit=Search
) in conjunction with the HTML_QuickForm_Controller
(http://pear.php.net/manual/en/package.html.html-quickform-controller.php
) add-on package.
I am using the QuickForm Controller package to build a multi-page form,
otherwise known as a "wizard". There will be 3 - 5 pages. If all the
info on the first page validates, the user is taken to the second page.
If not, then the errors are highlighted. Since the whole form has a lot
(100+) fields, the multi-page format is necessary.
Within this multi-page format, I wanted to do something like the following:
1) On the first page, the user is asked "How many books do you have?"
2) If the user chose 5 books on the first page, then 5 sets of fields
will be shown on the second page, each with fields such as title,
author, isbn, etc.
3) For this example, we will assume that the person cannot have more
than 10 books
The QuickForm Controller package uses session variables to hold data
from each page of the wizard. The thing is, I cannot how to access a
piece of information (session variable) from another page. I.e.,on page
2, I want to be able to say "if 2 books were specified on page 1, then
use a loop to add xyz form fields for each book."
If I were using session variables directly myself, I would know how to
do it immediately. But while the QuickForm and the QuickForm add-on
package are both very powerful, they are also very complex.
The reason I am using them is that creating a complex multi-page form
(with so many form fields and umpteen validation rules) would quickly
turn into spaghetti code without such libraries.
So, anyone have experience with this or a useful link?
Thanks in advance!

PS: David Sklar's PHP Tools book has information on the main QuickForm
library, but not on the Controller add-on. It seems that online
information for the controller is quite scant.
