Relationship between fields and tables

  • I’m doing a book database. Obviously books have authors. These authors have not just written a book than I have on file.
    How can I do to have in the form a drop down box with the author to select for the book by insert on database?
    I thought to relate the archive books with that of the authors.
    What is better to use taxonomies, relationship field types or repeater fields?
    Thanks and sorry
    I’m a bit new in ACF

  • Hi @boxcarlo

    I’m afraid I don’t understand your question, so forgive me if I’m wrong.

    If you want to add the authors of the books, I believe the best thing to do is to use a custom post type for the authors and then you can use a post object field type to set the author. By using a custom post type, you can specify more fields and custom query in the future.

    Also, if a book has more than one authors, you can set the “Select multiple values?” option on the post object field or use a repeater fields for the authors.

    I hope this helps 🙂

  • Hi James and thanks

    I apologize if I messed up
    I would like to store books by choosing the author via a selection box.
    This means, for example, that the same writer who wrote more than one book may appear on more than one record books.
    Example:
    Joseph Conrad wrote Lord Jim and The Shadow Line. If I put on file the book Lord Jim, as a writer I have to put Joseph Conrad.
    The same thing must I do to store The Shadow Line.
    But I think it is not necessary to enter another time Joseph Conrad into the book data. In fact, if I have the authors archive, Conrad is already registered and you only need to choose him from a selection box, but will have to be dynamically linked to the archive authors.
    This is what I would do and would like to know how to do it using ACF.

    I hope I have clarified my request.

  • Hi @boxcarlo

    Thanks for the explanation.

    Like I said before, I think the best way to achieve this is to create a custom post type to store the authors. That way, it will be more flexible and easy to manage. You can use a plugin like Custom Post Type UI to create the custom post type. After that, just link the books to the authors by using the post object field type.

    I hope this makes sense 🙂
