Ordering process advice needed, ?_POST vs. DB

[eluser]jabbett[/eluser]
You should store each selection in the user's session. You get cleaner code, and if you initialize the session appropriately, your user can automatically return to the ordering process at the step he last completed (e.g. if he browses away).

See the section of the User Guide that deals with the Session class for more information.
