PDF-Forms is a service provided by PDFzone.com | http://www.pdfzone.com/ __________________________________________________________________
First, I have a form that works and can submit. What I want to do is have the web server receive the fdf information and save it back to a pdf file.
What I need is for users to be able to fill out the pdf and submit it, and then have workers on the server side be able to download pdf documents that have been fillled out (hopefully named according to the name filled out on the form).
If your form isn't a large file, and you can stand a some extra transfer time, you could submit as PDF instead of FDF and by-pass the merge altogether.
A simple cgi script can receive and write the PDF.
I use a technique where the PDF gets submitted as post data to the cgi, and bury the file name in a get data string in the submit URL like:
http://your.server.com/cgi-bin/perlscript.cgi?filename=nameFromFieldInPDF
Second, I want to be able to check the form when it is submitted. I would like to be able to determine that all the required fields are filled in.
This includes some conditional fields that only should be filled in if a certain box (or at least one or several specific boxes) is checked.
Writing a check for field conditions into a submit button in Javascript isn't difficult, but you will need some understanding of Javascript to write this yourself.
If you aren't familiar with Javascript, or a server side scripting language, you might find yourself spending a good deal of time learning or a bit of money to someone else to get this project done.
Good Luck,
Cliff
