I have a pdf that currently people fill in, print out, hand to a receptionist who scans the paper form into a pdf, enters the form fields into a web form, attaches the scan to the web form and submits that. This is dumb.
What I want is a PDF form that once filled out the user can press a submit button. That submit button sends a post request to a web server with the form fields and the completed form. So far I can do half of that, submit the fields to a web site where they show up in POST, and the server's response gets returned to the user as a PDF, at least in Acrobat pro it does. Reader throws an error, but I am hoping that if the server returns a PDF reader will open it.
What I need is the submit button to send the fields to the server, along with a copy of the completed form. I can catch it with PHP and do everything I need from there. Preferably I would like both in the same transaction, but if not I can work around it.
