Following on from this post:
List all posts in custom post type by taxonomy
How would I go about doing the same as above with a Custom Post Type called Area, but looping through the child-categories to get something like:
-
Primary Area
- Post
- Post
- Secondary/Child Area
- Post
- Post
- Post

Reset to default 0This only takes care of two levels. You could make a recursive function, if you have 'unlimited' levels.
$custom_terms = get_terms('custom_taxonomy');
/**
* Loop through all taxonomies
*/
foreach($custom_terms as $custom_term):
// Reset query (for good measures sake)
wp_reset_query();
// Set the args (getting ready to get posts that are in the given taxonomy)
$outer_args = array(
'post_type' => 'custom_post_type',
'tax_query' => array(
array(
'taxonomy' => 'custom_taxonomy',
'field' => 'slug',
'terms' => $custom_term->slug,
'post_parent' => 0 // This means that it's only top-level taxonomies included
)
)
);
// Get the information for the outer loop.
$outer_loop = new WP_Query( $outer_args );
if($outer_loop->have_posts()):
echo '<h2>'.$custom_term->name.'</h2>';
// Loop through outer loop
while( $outer_loop->have_posts() ):
$outer_loop->the_post();
$outer_loop_ID = get_the_ID();
