If we peek into the global $wp_taxonomies variable we see the associated object types. There might be better ways to do this or even core functions, but you could try the following: function wpse_172645_get_post_types_by_taxonomy( $tax = ‘category’ ) { global $wp_taxonomies; return ( isset( $wp_taxonomies[$tax] ) ) ? $wp_taxonomies[$tax]->object_type : array(); } then for the … Read more
This is the answer to the question 🙂 <?php $args = array( ‘post_type’=> ‘services’, ‘areas’ => ‘painting’, ‘order’ => ‘ASC’ ); $the_query = new WP_Query( $args ); if($the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); // content goes here endwhile; wp_reset_postdata(); else: endif; ?>
The idea of term groups was to have a term with multiple aliases. This feature doesn’t seem to be fully backed and is therefore practically never used.
Your code is correct, well almost correct. On first view, I must confess, I missed it too. You have two syntax errors in your code. If you look closely, ‘parent ‘ and ‘parent’ is not the same. You should not leave blank spaces between single quotes (‘) and arguments. Also, you don’t need to add … Read more
The hierarchy is cached and it’s not invalidated properly. This is a bug, still unresolved as of WP 3.1. A workaround would be to call delete_option(“{$taxonomy}_children”); directly. See the _get_term_hierarchy() function.
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’);
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
