We allow our customers to create their own template / docx files containing pre-defined "tags" that get replaced with data from our database. All of that has been working great for years.
Today for the first time someone tried to attach a file to their template / docx file before uploading it to us. Apparently, this is some kind of insurance certificate that contains signatures, so they have to include that as is with the document. The file is a PDF stored on their computer and it seems like they can "attach" it to a normal Word document.
Can phpdocx preserve that kind of attached file as we replace variables in the docx template, and then convert that to a PDF ?
