Publishing a Post Only in Its Sub-Category?

  • I have a category titled “news” then a test sub category called “news-sub”. By default, if you publish a post under news-sub it’s displayed under both the news category and the news-sub category. That’s alright. But sometimes, I would like the post to be published under only the sub category and not the parent sub category. I thought it would be as easy as just checking the category “news-sub” and not “news”. But the post still gets published under both the sub category and parent category when you publish it just under the sub category. ??

    So, is there a way to publish a post so it is displayed only in its sub category and not both the parent category and sub category? Any help would be tremendously appreciated! ??

    Try it with this in your theme’s functions.

    add_action( 'pre_get_posts', 'my_post_queries' );
function my_post_queries( $query ) {
  // not an admin page and is the main query
  if (!is_admin() && $query->is_main_query()){
    if(is_category()){
      add_action('posts_where', 'current_category_only');
    }
  }
}

function current_category_only($where) {
  $current_cat = get_query_var('cat');
  if($current_cat){
    global $wpdb;
    return " AND ( $wpdb->term_relationships.term_taxonomy_id IN ($current_cat) ) AND $wpdb->posts.post_type = 'post' AND ($wpdb->posts.post_status = 'publish' OR $wpdb->posts.post_status = 'private')";
  }
  return $where;
}

    I added that to my functions page and when I submit a post only under “news-sub” it still gets displayed under “news” as well. I even tried refreshing my permalinks. Perhaps I have to delete something from my current functions.php file to in order for your code to work??
