WWYD if you needed to build a giant form that would send results via Email

Im talking hundreds of fields. Wuforms is awesome, but out of the question. PHP based. Any thoughts?

u expect people to fill out these "hundreds" of fields in one session?

Id build a giant form and get it to send me the result via email.

It’s actually an order form, they wouldn’t be filling out every field, just adding numbers next to the parts they need and submitting.
