I am able to successfully send my XML data to my PHP/MySQL server via a PHP script and a 'Http submit' button in the PDF. (I get time out errors if I try submitting XML data via Adobe Acrobat Pro 8 and Pro 9, but it works successfully without errors in Adobe Reader 8 and 9 - wierd)
Once the XML data is received, the PHP/MySQL server script processes the XML data and needs to send back the resulting data/answer right back into the PDF.
How do I accomplish this? Where should I start looking?
Example: User submits Date and Time they would like to book a meeting room.
Server replies back if the meeting is is availble, and if not available it gives alternate dates and times.
When you submit information to your server via an HTTP you can only send back a PDF for Acrobat/Reader to respond. You ar not talking to a browser so sending back HTML is not an option. It is not a communictaions vehicle between the two. If you want that I would suggest a web service approach.
