I have a hidden form field in a PDF file, that contains a default value (a site ID), so when the form is submitted via email the default value is passed. What I need to do is write a little program that will change the default value of the hidden field to a different site ID (of which I have a couple of hundred) and save the PDF file with a new name (so it can be emailed to all the users at that site). CAM::PDF is the only module that I have been succesful with in accessing form values, but the hidden form field is giving me trouble as it won't let me override the default value.
I read the file in successfully, grab the form field object, set the value, and save the PDF file. When I open the newly saved PDF file it is the old default value, not the new value. I can use the same process and set visible form fields and they work OK. Does anyone have any suggestions that might help me get over the hump with this issue?
