FDF - how to check a checkbox?

Question

I\'m using FDF to populate a PDF template. On my PDF template, I have a checkbox and radio field called c1 and r1 respectively. What\'s the syntax I should use in my FDF f

Answer 1

For all those for which above answers didn't work out I've been searching for a solution for a long time with PDF version 1.6. I then exported the form data directly with Adobe Acrobat Pro DC and found another way which in the end worked out for me:

<> // this is non-checked
<> // this is checked

As for the checked value (/Yes) this depends on the export value of the field. By standard the checkboxes in PDF forms have the value "yes" in the language your program is in.

Hope this helps others as well.
