filling an dynamic form with pdftk

Hello everyone!

I would like to get some ideas, eventually a workaround on how to solve this issue of this project of mine.

I would like to save some dynamic form data to a mysql database and then to offer to possibility to download back the filled in form with data from the database...and here is the issue, the form should be still dynamic.

Untill now i was doing this with pdftk and static forms but from what i understand pdftk cannot fill dynamic forms. So does anyone have an ideea how to achieve this some other way?
