Use the pre_delete_term hook, which fires before the actual deleting occurs, so the relationships will still be present. function wpse_296972_pre_delete_term( $term_id, $taxonomy_name ) { if ( $taxonomy_name === ‘organization’ ) { $objects = get_objects_in_term( $term_id, $taxonomy ); // Do something with $objects. } } add_action( ‘pre_delete_term’, ‘wpse_296972_pre_delete_term’ );
get_terms returns array of terms and not only one term, so you can’t do $terms->slug, because it makes no sense at all… If you want to display all terms, you’ll have to loop through them: $terms = get_terms( array( ‘taxonomy’ => ‘brand’, ‘hide_empty’ => 0 ) ); if ( ! is_wp_error($terms) ) { // it … Read more
The problem is ambiguity, you can’t just put in ‘relation’ => ‘OR’ in the main parameter list, because how would WP_Query know if it’s for the tax_query and not the meta_query? For how it’s supposed to work, and where the relation parameter goes we need to refer to the official docs for WP_Query which gives … Read more
Unfortunately, it looks like the code that runs your widget will not let you add your image: The code here shows that a loop is creating the unordered list and there are no filters where you can inject your own image. You can add your own code to the plugin, but it’s not recommended as … Read more
You can try getting all the posts IDs from the first taxonomy $objects = get_posts( array( ‘category’ => ‘history’, ‘numberposts’ => -1, ) ); foreach ($objects as $object) { $objects_ids[] = $object->ID; } Then get the terms from the second taxonomy associated with them: $collections = wp_get_object_terms( $object_ids, ‘collections’ );
What about: $taxName = “tvr_amenity”; $terms = get_terms($taxName,array(‘parent’ => 0)); foreach($terms as $term) { echo ‘<a href=”‘.get_term_link($term->slug,$taxName).'”>’.$term->name.'</a>’; $term_children = get_term_children($term->term_id,$taxName); echo ‘<ul>’; foreach($term_children as $term_child_id) { $term_child = get_term_by(‘id’,$term_child_id,$taxName); echo ‘<li><a href=”‘ . get_term_link( $term_child->name, $taxName ) . ‘”>’ . $term_child->name . ‘</a></li>’; } echo ‘</ul>’; }
To fully understand the difference between get_categories(), get_category() and get_term_by(), you need to have a look at how these functions are constructed. get_categories($args) as its name suggest, get a list of all categories created on the site. This function can be found in “wp-includes/category.php” lines 39 to 66 39 function get_categories( $args = ” ) { 40 $defaults = array( ‘taxonomy’ => ‘category’ ); … Read more
Ok, I revisited this and revised my answer.. But like I said before: the hook you are (trying) to use won’t/can’t work for the purpose you are aiming for, simply because its only occurrence is in class-wp-posts-list-table.php, which nomen est omen is used to show the post list, the right place should be class-wp-terms-list-table.php. 1. … Read more
I found an answer to this at https://wordpress.stackexchange.com/a/105079/40536 I modified my code to the following: <form action=”<?php bloginfo(‘url’); ?>/” method=”get”> <?php $term_id = 279; $taxonomy_name=”categories”; $termchildren = get_term_children( $term_id, $taxonomy_name ); $children = array(); foreach ($termchildren as $child) { $term = get_term_by( ‘id’, $child, $taxonomy_name ); $children[$term->name] = $term; } ksort($children); echo ‘<select name=”‘ . … Read more
As already hinted by @Milo, check if you have terms before appending your tax_query You can try the following: (Requires PHP 5.4+ due to short array syntax, revert to old syntax if necessary) $args = [ ‘post_type’ => ‘product’, ‘posts_per_page’ => 15, ‘paged’ => $paged, ‘post__not_in’ => $exclude, ‘s’ => $filter, ]; // Append our … Read more
