Hi Simon --
Super handy ... if I could only make it work ;-)
What value does this function take for $field_group? Individual fields have "Field Label" and "Field Name", which I set in ACF's UI. But there's nothing similar for the Field Group.
In ACF, I have a group "My Group". Should I pass "My Group"? "my-group"? Some id value that I need to find in the DB?
