i am working on a php application which opens a pdf form (created with acrobat 9 standard), fills it with user data, saves it as a form and sends this form to the user by email, so he cann fill the rest of the form.
This works fine for pdf forms, which have not the extended rights enabled.
As soon i enable it, the user will get the message that the form has been modified, and he is not able to fill out the other fields any more.
Now my question:
1. Is there any php library which can activate the extended rights of a pdf form after i filled some of the fields?
