I have done a "lets call it" registration form with several data fields an 2 signature fields.
The form is working fine. Also tracker is doing his job. My problem is that my 2 signature fields are blank in the export file. It doesnt matter if I export to csv or to xml.
My goal to export "some" of the given attributes from digital signature as name & email & the timestamp (the signature was done).
How can I do this?
All other data is no problem.

btw. I´m working on windows XP an with acrobat 9 standard. The form base was originally designed in excel.

Is there anyone who can help me with this?

thank you PJ

A digital signature is not a data field. Signing a PDF causes Acrobat to make a checksum of the entire PDP and then store it in the PDF. This checksum is then checked to validate that changes have not been made to the PDF.

There is all kinds of info in the signature, but none of it is actual field data. You can however use a script to extract info from the signature and then include this info in hidden form fields that will appear in the exported data. See the JS reference for details
