I tried to get the values of the selected checkbox fields to post them in a customized e-mail notification by using this code in functions.php:
The form looks like this:
The form-ID of the checkbox is 3, respectively the three value-IDs should be "3.1", "3.2" and "3.3".
If I use this code, I don't get anything back.
What is wrong with this? Unfortunately I'm new to PHP programming...
Any help is greatly appreciated!
P.S.: I'm using the current version of GF
