There are probably some better ways to do this but you can always do a three simple foreach loops. I wrote an example function that does the job well and should serve you as a good starting point: function print_taxonomic_ranks( $terms=”” ){ // check input if ( empty( $terms ) || is_wp_error( $terms ) || … Read more
If you want to keep ‘authors’ as the base slug in the permalinks, i.e. example.com/authors/stephen-king/ for the ‘authors’ CPT, example.com/authors/stephen-king/the-shining/ for the ‘books’ CPT and example.com/authors/stephen-king/the-shining/chapter-3/ for the ‘chapters’ CPT, WordPress will think pretty much everything is an ‘authors’ post or a hierarchical child of an ‘authors’ post and, since that is not the case, … Read more
When Working with pages you can select a parent page and that value is saved as the parent page id number in the child page’s post_parent field in the database. In your case, you are using a custom post type so you would need to create your own metabox for the parent page; something like: … Read more
No core hacking needed — thanks to: HOOKS. Hooks allow to fix the issue with a nice combination of a filter replacing “–” by “, ” before output and an “if” block to make sure the output is not also filtered for the admin interface 🙂 and finally, saving all your tags with comma in … Read more
Thanks to Ivaylo for this code, which was based on Bainternet’s answer. The first function below, get_term_top_most_parent, accepts a term and taxonomy and returns the the term’s top-level parent (or the term itself, if it’s parentless); the second function (get_top_parents) works in the loop, and, given a taxonomy, returns an HTML list of the top-level … Read more
Finally I’ve found a working solution. The cartoon-series can be registered as you did but episodes custom post types can not be hirarchical (I think WordPress expects parent content be the same type as child content if the relationship is set using post_parent in wp_posts database table). When registering episodes, the rewrite rule must be … Read more
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
The simple answer is that terms in hierarchical taxonomies can have child terms. But what else? ‘hierarchical’=>false When you specify a ‘hierarchical’=>false you get the following type of metabox which is the metabox format WordPress also uses for Post Tags: ‘hierarchical’=>true However when you specify ‘hierarchical’=>true you get the following type of metabox which is … Read more
Use wp_list_categories with the ‘taxonomy’ => ‘taxonomy’ argument, it’s built for creating hierarchical category lists but will also support using a custom taxonomy.. Codex Example: Display terms in a custom taxonomy If the list comes back looking flat, it’s possible you just need a little CSS to add padding to the lists, so you can … Read more
After combining a bunch of pieces of other answers I got it working! So here’s the solution for those of you who are struggling with this too: This post and this one helped me out some, so thanks to those guys. Note, all this code, plus your initial custom post type and taxonomy registration code … Read more
