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.
