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.

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/
You need to pass an additional argument to get_terms(). The default is to hide “empty” terms– terms which are assigned to no posts. $terms = get_terms([ ‘taxonomy’ => $taxonomy, ‘hide_empty’ => false, ]); EDIT: Incase you want to display the name or the slug of the enlisted custom taxonomies being held by the $terms variable … 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
