Index page of posts tagged with two separate taxonomies

Question

I have a custom post type Book which has three custom taxonomies:

• Genre
  • Fiction
  • Non-fiction
• Media Type
  • Book
  • eBook
  • Audiobook
• Audience
  • Kid
  • Teen
  • Adult

My goal is to create index (aka archive) pages of many of the different combinations of two or all three taxonomies. For example, I want a "Kids Fiction" page and an "Adult eBook" page. If at all possible, I want to do this without any PHP because custom PHP tends to have lots of hardcoded properties that make the template hard to maintain.

How do I create index pages with different combinations of multiple taxonomies?

Answer 1

This is very similar to this question.

Try something like this in your template and change the AND condition to AND/OR as appropriate depending on what combination you want.

$args = array(
'post_type' => 'Book',
'tax_query' => array(
    'relation' => 'AND',
    array(
        'taxonomy' => 'Genre',
        'field' => 'slug',
        'terms' => array( 'Fiction' )
    ),
    array(
        'taxonomy' => 'Media Type',
        'field' => 'slug',
        'terms' => array( 'eBook' )
    )
)
);
$query = new WP_Query( $args );
