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
This isn’t possible “out of the box”… The default ‘orderby’ options are (ascending or descending) ID name Default slug count term_group These are all detailed in the codex. — That said there are some clever ladies & gents here. If anyone can solve it, one of these guys can i’m sure!
Here is another way to do something similar, with one SQL query: static public function get_terms_by_post_type( $taxonomies, $post_types ) { global $wpdb; $query = $wpdb->prepare( “SELECT t.*, COUNT(*) from $wpdb->terms AS t INNER JOIN $wpdb->term_taxonomy AS tt ON t.term_id = tt.term_id INNER JOIN $wpdb->term_relationships AS r ON r.term_taxonomy_id = tt.term_taxonomy_id INNER JOIN $wpdb->posts AS p … Read more
Have you tried using the WP_Query class? You might find it’s easier to use the built-in tools for this instead of a custom query from scratch. Something similar to the following should work for you: <?php $args = array( ‘post_type’ => ‘recipe_cpt’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘recipe_tx’, ‘field’ => ‘term_id’, ‘terms’ => 37 … Read more
This will add a field called ‘TERM META TEXT’ to your categories. I did take out the nonce but I really think it should go back in. Also, it’s just better to have some sanitization vs. none. This example includes javascript and CSS hooks which you may or may not need but you can quickly … Read more
I’m afraid this isn’t possible natively (yet?). See this trac: http://core.trac.wordpress.org/ticket/18106 Similarly on the taxonomy admin page the post count reflects all post types. (I’m pretty sure there is a trac ticket for that too) http://core.trac.wordpress.org/ticket/14084 See also, this related post. New solution Having written the one below, I’ve released a much better way (alteast … Read more
Yes, just pass in the parent parameter to get_terms when you call it, as Michael pointed out. Since WP 4.5 this is the recommend usage: $myterms = get_terms( array( ‘taxonomy’ => ‘taxonomy_name’, ‘parent’ => 0 ) ); Prior to WP 4.5 this was the default usage: $myterms = get_terms( ‘taxonomy_name_here’, array( ‘parent’ => 0 ) … 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
Object cache everywhere WordPress tries to reduce the number of database queries as much as possible. For example, anytime you get a meta field or a taxonomy field, before querying the database, WordPress looks if that that was already queried and stored in cache, and returns it from there instead of querying the database. The … Read more
The function you are looking for is get_term_by. You would use it as such: <?php $term = get_term_by(‘slug’, ‘my-term-slug’, ‘category’); $name = $term->name; ?> This results in $term being an object containing the following: term_id name slug term_group term_taxonomy_id taxonomy description parent count The codex does a great job explaining this function: https://developer.wordpress.org/reference/functions/get_term_by/
