multiple entry forms !!

hi looking for some advice I have a site in progress. user to it have to enter a LOT of information (it will contain a club directory) in order to try and make it a less unpleasant experience for the user, I want to give them 7 smaller input forms, each one following the other what would be the correct way to do this, one very large, complex coded php conditional form that does everything, or several smaller ones ? if I use one form, it will conatin rather a lot of code, but execution would all be handled by the form itself but if I use multiple smaller forms, each form would need to process the previous forms input, and then display it's inputs for entry I am also using sessions, which adds a little to complexity any general good coding practice tips/links would be helpful thanks _scott
