I’m having the same problem. I’m using the documented code (which, I mean, it’s documented, shouldn’t it just work?). Returning the same error as aaron. All I want to do is return all checked checkbox values in an array, and comma separate them. Is that not what the documented code is supposed to do? Some help with this would be great.
The documented code that doesn’t work.
<?php echo implode(', ', get_field('field_name')); ?>
