Here is one of the possible solutions. There are some other recursive solutions for multi child levels. According to your question which is a one child level. The quick test proved to work which is conducted with default themes and default taxonomy Category. // first get the parent only $terms // because of unknown sorting … Read more
I was under the impression you can’t have categories and tags on custom post types? You can have categories and tags on custom post types! But I can’t see how Taxonomies and Terms are the same? But they are the same, Categories are a taxonomy, as are post tags, they’re stored in the database the … Read more
So if you’re sure you want to delete the actual term as well as the relationship that assigns the term to the post, this will do it (tested and works for me): delete term from wpterm_taxonomy term, wpterm_relationships rel where term.term_taxonomy_id = rel.term_taxonomy_id and rel.object_id IN (1) ; And obviously replace the ‘1’ there with … Read more
Credit for this answer goes entirely to CodeMascot: Create and move terms for taxonomies After troubleshooting, I believe the issue is because I initially created the custom taxonomy with the name Purpose, but then changed it to purpose at another time. Calling $object->taxonomy returns Purpose on the affected term, while all the others listed in … Read more
I suggest that that @SallyCJ’s approach makes much more sense if you can do it this way: simply break down wherever these ID’s get written to store the tax names at that point. However it seems like figuring out which Taxonomy each Term ID is in and then using that to generate the tax_query part … Read more
I ended up using wp_query instead because I couldn’t make wp_get_recent_posts work no matter what I tried. For anyone who needs this functionality in the future, here’s the code I used: // Get the ID of the current posts’s term $terms = get_the_terms( $post->ID, ‘comic-series’ ); // Only get the parent term and ignore child … Read more
how to check if each term is attached to the current post You can do that using has_term() which defaults to checking on the current post in the main loop, hence you can omit the third parameter (the post ID). So for example in your case: $class = has_term( $term->term_id, $term->taxonomy ) ? ‘active’ : … Read more
It’s actually pretty simple: You’ll want to use an OR relation, and use the NOT EXISTS operator for selecting posts that are not assigned to any terms in the specified taxonomy. $tax_query[] = array( ‘relation’ => ‘OR’, array( ‘taxonomy’ => ‘location’, ‘field’ => ‘name’, ‘terms’ => $location, ), array( ‘taxonomy’ => ‘location’, ‘operator’ => ‘NOT … Read more
I solved this issue after Rup in one of the comments pointed out that the parent categories dropdown was most likely the culprit. Sure enough, that was the issue. It appears WordPress was attempting to populate the dropdown with 15,000 items which were causing an excessive query to be made to retrieve those items. The … Read more
count how many posts are tagged but only include those posts that belong to a specific category You can’t do that via get_terms(), but you can make a WP_Query query and use the $found_posts property to get the total posts. So for example, in your foreach, you can use the tag and cat parameters like … Read more
