I have a custom post type 'books' which I store different custom fields of information about books.
I want to use posts and link the posts I write (in categories such as news, or offers) to the books.
For example, when the user is viewing the book information page, I want to be able to display all the posts in news category related to that book.
I was able to do this using a custom field and assigning the book id to the news. But what if I have a news that's related to a lot of books?
Is there any way to file all the Custom Post titles to a taxonomy? What's the best way to do this?
