I came up with a solution for your first question. i.e the tax metabox that only suggests terms from existing terms list but does not allow you to add new terms. The solution is jQuery based and modifies the default behavior of the tags (i.e non heirarchical taxonomies) meta box. Limitation: Currently it only allows … Read more
You can block addition of new terms with a filter on pre_insert_term. The source is helpful in working out what you can do. add_action( ‘pre_insert_term’, function ( $term, $taxonomy ) { return ( ‘yourtax’ === $taxonomy ) ? new WP_Error( ‘term_addition_blocked’, __( ‘You cannot add terms to this taxonomy’ ) ) : $term; }, 0, … Read more
get_terms supports a meta_query which calls a new WP_Meta_Query parameter as you can see here. To query your terms with your desired meta, you could change your function call to something like this: $args = array( ‘taxonomy’ => ‘categoria-de-productos’, ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘ASC’, ‘hide_empty’ => false, ‘hierarchical’ => false, ‘parent’ => 0, ‘meta_query’ … Read more
There is a plugin by Scribu called Category Checklist Tree that disables this “feature”.
This answer is essentially the same as Ünsal’s, but I’d like to elaborate a bit because despite being right his answer didn’t help me (I was just trying to remember what I’d done in the past, I should have read his more carefully and I would have figured it out, but I think for others … Read more
Add the following to your theme’s functions.php: /** * Tests if any of a post’s assigned categories are descendants of target categories * * @param int|array $cats The target categories.

Here are some thoughts on the issue, but please note that this is by no means a conclusive answer as there may be some things I have overlooked however this should give you an insight to the potential gotchas. Yes, technically there could be consequences. Where calling wp_defer_term_counting(true) becomes truly beneficial is when for instance … Read more
This should work for you: $taxonomyName = “age”; //This gets top layer terms only. This is done by setting parent to 0. $parent_terms = get_terms( $taxonomyName, array( ‘parent’ => 0, ‘orderby’ => ‘slug’, ‘hide_empty’ => false ) ); echo ‘<ul>’; foreach ( $parent_terms as $pterm ) { //Get the Child terms $terms = get_terms( $taxonomyName, … Read more
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; ?>
