I'm developing a Joomla site.
There are 3 features needed:
- file management, to grant access to an user to certain PDF files
- PDF edit to insert the user's name
- PDF edit to protect the pdf with the user's password
For example, an user logs in and the site redirects to the download page and allow access to several PDF files.
If he downloads a PDF file, that PDF must have his name at the bottom (or as a watermark) and must be protected for opening with the same password the user uses in Joomla.
There are Joomla extensions to provide PDF file management, but there aren't any extensions with the functionality to insert the user's name and protect it with a password.
How can I achieve this?
