I've written a PHP server script that downloads a FDF file to the user when he clicks on a button. This FDF was generated with dummy values for form fields with Acrobat Pro from the original interactive PDF template. I replace the dummy arguments in the PHP code and download the result to the user.
My problem is that Acrobat starts up but cannot find the corresponding PDF. I've inserted the complete URL of the template PDF in the /F and/UF fields of the FDF, but it doesn't seem to work. The template URL has the same path as the FDF (except for the actual filename extension). What might I be doing wrong?
