I want to have a “like” field for every post, this field supposes to hold the number of likes for every post. But the problem is i don’t want it to be visible when editing post and no one except my code can change it. How can i do this with acf ?
Create a field group for just that field. In the Location panel under Rules, set Show this field group if to Current User Role is equal to Administrator - that way, your users won't see the field group but you still will (good for debugging).
