In looking at the WP_Tax_Query class in /wp-includes/taxonomy.php, I found that there is a ‘include_children’ option which defaults to true. I modified my original get_posts() call with the following, and it works great: $pages = get_posts(array( ‘post_type’ => ‘page’, ‘numberposts’ => -1, ‘tax_query’ => array( array( ‘taxonomy’ => ‘taxonomy-name’, ‘field’ => ‘term_id’, ‘terms’ => 1, … Read more
You would want to use the NOT EXISTS operator along with passing the taxonomy slug, which tells the query not to include any of a chosen category from your custom taxonomy inside the loop. To exclude all posts that are in the taxonomy “fruit” (regardless of fruit kind), here is the snippet: $args = array( … Read more
The tax_query parameter is an array of arrays, not just an array. This: ‘tax_query’ => array( ‘taxonomy’ => ‘video_type’, ‘terms’ => ‘episode’, ‘field’ => ‘slug’, ‘include_children’ => true, ‘operator’ => ‘IN’ ), Should instead be this: ‘tax_query’ => array( array( ‘taxonomy’ => ‘video_type’, ‘terms’ => ‘episode’, ‘field’ => ‘slug’, ‘include_children’ => true, ‘operator’ => ‘IN’ … Read more

You can always override the template that will be called with the template_include or a related filter, but this might hide deeper problems with custom archives. As I understand it, you want to use the following structure: /glossary/ should be an archive page for all sumo-glossary-term posts /glossary/[letter]/ should be an archive page for posts … Read more
Try this $custom_terms = get_terms(‘custom_taxonomy’); foreach($custom_terms as $custom_term) { wp_reset_query(); $args = array(‘post_type’ => ‘custom_post_type’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘custom_taxonomy’, ‘field’ => ‘slug’, ‘terms’ => $custom_term->slug, ), ), ); $loop = new WP_Query($args); if($loop->have_posts()) { echo ‘<h2>’.$custom_term->name.'</h2>’; while($loop->have_posts()) : $loop->the_post(); echo ‘<a href=”‘.get_permalink().'”>’.get_the_title().'</a><br>’; endwhile; } } We get all the terms of a … Read more
