Use get_term_children() $term_id = 2; // use get_queried_object()->term_id; to get the current term id $taxonomy_name=”mypages”; // use use get_queried_object()->taxonomy; to get the current taxonomy name $countchildren = count (get_term_children( $term_id, $taxonomy_name )); echo $countchildren;
The dynamic filter “term_{$field}” is probably what you’re looking for, where the field is “name.” One approach is to have an array of names and their pseudonyms, then do a check-and-return on them so they’ll display the replacement. add_filter( ‘term_name’, function( $value ) { $terms = [ ‘old’ => ‘new’, ]; // basic example check, … Read more
Before you start theme development, I suggest you familiarize yourself with general WordPress Usage & Terminologies. Taxonomy: In general taxonomy means classification. In WordPress, posts, pages, custom post types etc. can be further classified by using different taxonomies. For example, you may have hundreds of blog posts. Now how do you classify them for better … Read more
The solution below will return posts associated with the queried term name or posts that use the term name in the post title, excerpt, or content. Note that we are using the human readable term name for the search, not the term slug, which isn’t ideal for searches since it could be hyphenated. First, add … Read more
To create a taxonomy, you should use register_taxonomy(). This function accepts three arguments: <?php register_taxonomy( $taxonomy, $object_type, $args ); ?> The documents on the codex are plenty self explanatory. Now, to insert a term into a taxonomy, you can use wp_insert_term(). Again this function accepts 3 arguments: <?php wp_insert_term( $term, $taxonomy, $args = array() ); … Read more
I have partly solved my own question so-to-speak. I’ve been trying to get post type relationships working for ages and the plugin relation post types as mentioned in my comment to Christopher’s answer. It is far from perfect, but I worked out how to get this plugin: http://wordpress.org/extend/plugins/relation-post-types/ – working (albeit not that pretty). The … Read more
You can get the parent category pretty simple: It’s assigned to the object. $cat = get_category( $q_cat ); // Get the ID echo $cat->category_parent;
I think you mean you want to create terms in your taxonomy? Have a look at this answer for detecting when a theme is activated. Then use wp_insert_term to insert the terms into your taxonomy.
You shouldn’t need to use a custom SQL query – stick to the built-in method wp_delete_post(). This will also clear out all term relationships too.
Not sure why I didn’t think of this earlier. I suppose I was hoping for a way to ‘hijack’ the default page to display something else… Anyway following my original method: If you want a custom admin page for a taxonomy, you can set ‘show_ui’ => false when you register it to suppress the default … Read more
