Thanks for answer @hube2
Then I will adapt my question: in your opinion is it better name the fields like prefix_author
, prefix_genre
, prefix_book_year
(where prefix is a unique prefix, that could be my name or the name of my client’s company) or book_author
, book_genre
, book_year
(where book identifies the post type)?
In the first case I can fall in conflicts if I will need to add another fields group to the same target.
