Hidden fields in PDF format are displayed when using DynaPDF 3.0 to merge PDF files

Question

Recently, I discovered that one of the php-based systems I need to code for plugins for updating is the version of DynaPDF lib from 2.0 to 3.0. The only thing I do is merge two PDF files into one.

The first pdf is a simple pdf, without form fields, only text and images. The second pdf contains a feedback form that can post its content to a specific URL. I have two text fields and three hidden fields.

Now everything works fine, except that the hidden form fields are clearly visible (i.e. nonHidden;)) in the finally merged PDF file.

Does anyone also stumble on this issue with DynaPDF?

thanks,

K

Answer 1

Have you tried to do the opposite? Add pdf2 first and then pdf1. How about using pdfAddFieldToHideAction to add hidden fields specifically?
