Using Custom Post Types (CPTs) in WordPress we can create our own custom content types besides the built-in Posts and Pages. Similarly custom taxonomies can be created similar to the built-in categories and tags. And then there are custom fields which can be attached to a CPT to set that content-type specific features/attributes.
In this article I go over registering a Books CPT, registering a Genre taxonomy to categorize the books, adding a custom field group consisting of Price, Author, Published Year and Purchase Link. I then share the templates, archive-books.php and single-books.php which determine how the Archive (list of books) page and individual book pages are displayed.
Note that he code can be used with any CPT, taxonomy and custom fields in Genesis if you understand how the entire solution is put together and operates. I have added comments in the code to make it easier for beginners.
