Custom taxonomy terms not showing as list Gutenberg Editor
Changing the slug of taxonomy works for me. Don’t know the reason behind it but it works.

get_terms – only top level
Your code is correct, well almost correct. On first view, I must confess, I missed it too. You have two syntax errors in your code. If you look closely, ‘parent ‘ and ‘parent’ is not the same. You should not leave blank spaces between single quotes (‘) and arguments. Also, you don’t need to add … Read more
Inserting terms in an Hierarchical Taxonomy
The hierarchy is cached and it’s not invalidated properly. This is a bug, still unresolved as of WP 3.1. A workaround would be to call delete_option(“{$taxonomy}_children”); directly. See the _get_term_hierarchy() function.
get_the_term_list without links in 3.1
wp_get_object_terms() returns the terms associated with an object (eg a post or a page or custom post) as text (normally in an array). From the Codex page for wp_get_object_terms() $productcategories = wp_get_object_terms($post->ID, ‘productcategories’);
Get the the top-level parent of a custom taxonomy term
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
Change order of Custom Taxonomy List
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!
Retrieve posts by term id custom query
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
How to modify a taxonomy that’s already registered
register_taxonomy() is the tool for the job. From the Codex: This function adds or overwrites a taxonomy. One option would be to copy the register_taxonomy() $args and modify them. However, that would mean that any future changes to the original register_taxonomy() code would be overwritten. Therefore, at least in this case, it’s preferable to get … Read more
How can I get only parent terms?
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
get_posts assigned to a specific custom taxonomy term, and not the term’s children
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
