I created a custom field using advance custom field plugin, and I selected in field type “user”, which actually is a dropdown containing all of the users. I then added this field to a custom post.
All users have a unique 4 digit number in their profiles.
My client wants that, instead of having the users displayed in this dropdown when creating a new post, he wants to have the name AND this 4 digit number that each user has in its profile.
Is there a way to modify the “user” field type to have it show additional information?
