This is a well-known problem, with 2 well-known solutions: 1/ store
the state in hidden fields or 2/ use sessions.

The form-wizard contrib app mentionned by DrBloodmoney uses the first
approach, which makes it "more general" since you can use it without
having to resort to sessions. OTHO, I didn't find it quite as easy to
use and flexible as I would have liked, specially when I had to fork
it to give users the possibility to navigate backward. You should
nonetheless give it a try first and see if it works for you. If it
doesn't, you may want to roll your own session-based solution.
