RE: [PHP4BETA] hidden variables !<form>

Use a serialized hash to store the old values, and pass that one hash from
page to page.

Each page adds new values to the hash and then re-serialises the hash to put
it in the hidden field.

I usually move within different portions of the same page, so if a
submission was incomplete I can easily show the section that still needs
completing.
