PDF/FDF Support

I'm trying to write a PDF form that people can fill in. I want to then take the data, store it in my database, and then recall the data, and display a filled in form with that data. I see two options. The first is to have acrobat post the entire PDF file and store the entire file. This option seems to be to be a little bit of a waste as much of the data is the same (the form). The second option is to have it post FDF data and then later turn that around and put it back into a form for people to view. Does anyone know of any good documentation on how to do this with PDF files, PHP, and a DB backend? ---------------- Thanks Jefferson Cowart Jeff@cowart.net Support Open Instant Messaging Protocols http://www.petitiononline.com/openIM/petition.html
