I have designed an Acrobat form and accompanying PHP script to process the form's submitted data. Is there a way to send a message back to Acrobat that can be displayed in the form after submission (e.g. as message to the user stating "The form has be successfully submitted")? Presently, any response produced by my PHP script appears as text in a newly created PDF.
I have tried echoing back FDF data (I exported an FDF file from that same form and am echoing that) with no luck and can't find any references online that show how to do this. This Adobe page (http://kb2.adobe.com/cps/325/325874.html) suggests that it is possible to dynamically update form fields from a remote server, but doesn't elaborate. Any information would be appreciated.
You can return an FDF that causes a pop-up window to be displayed, or you can return data that gets displayed in a form field. For a Perl script fragment that demonstrates how to return an FDF response that displays a message in a pop-up, see: https://acrobat.com/#d=COn7HhOSHIuGo4R*ByS3uw
