Best way to do this

[tdnxxx444]

I have a form in which I have queried some data based on a primary ID key and also have the user fill in my form fields. I then submit this form to another page.

My question is should I pass the queried data in hidden form fields to the next page, or just pass the primary ID key via one hidden field and query the data again on the next page?

it is up to you of course. but given that anything can be submitted in the hidden fields if i hack the form and do it manually, i would use the id to re-query the data instead of caching them in the form. another way to cache though is to use session variables.
