Multi-Step Form Data

A common approach I have seen to accomplish this is just to pass data between pages in hidden inputs. A surprisingly large number of high profile sites use this technique.

It eliminates alot of the issues with storing form data in the database, mapping that data to a user, and knowing when to expire that data from the table. (If a user does 2 out of 3 steps and stops).

I have used both techniques, and prefer to just use hidden inputs.
