Here is the structure I have:
Authors
- Author1
- Author2
- Author3
Books
- Book1
- Book2
- Book3
I have a list of quotes. Each assigned to specific Author and Book. (For example: I have a quote from Author1, Book2 and quote from Author1, Book3)
How do I get a list of Books of an Author based on the Quotes I have in database?
I tried to follow the idea of how to get tags specific to category http://wordpress.org/support/topic/get-tags-specific-to-category?replies=38 but didn't figured out how to interpret it for my example. I lack in php knowledge.
please help!
