So you want to watermark the pdf with some data from the user.

You would have some options to do that.

The easier would be if you don't do it on a uploaded file, instead you generate html content and convert html to pdf on the fly.

But if you need to do it on a uploaded file, maybe this could help you: Writing/Drawing over a PDF template document in PHP
