FillPDF for Drupal 7 now has entity support
Drupal 7 has long been lacking full support for filling data from anything other than nodes and webforms. Users have had to install patches to meet other needs.
That ends today. WIth the release of 7.x-1.15-rc1, entity data can now be filled into PDFs.
See the updated documentation (Installation and Usage) to learn how!
If you still have questions, keep an eye out on Twitter; additional support options via Patreon are coming soon!
