Your problem isn’t line 780 of ../wp-includes/class-wp-query.php So it’s a little bit hard to help because you’re not showing the actual code that’s at fault. But you’re probably trying to reference a post category by its data object instead of using the integer id. For example you might have something like this: $mycategory=get_category_by_slug(‘a-category-slug’); $args = … Read more
The get_callback part is generated within the WP_REST_Controller::add_additional_fields_to_object() method with: $object[ $field_name ] = call_user_func( $field_options[‘get_callback’], $object, $field_name, $request, $this->get_object_type() ); That means the callback has four input arguments: ‘get_callback’ => function ( $object, $field_name, $request, $object_type ) { // … } and for the requested category object, we can get the term id with: … Read more
You can use get_the_term_list() to output a comma-separated list of links to product categories: <?php while ( $loop->have_posts() ) : $loop->the_post(); ?> <li class=”product-list__item”> <a href=”https://wordpress.stackexchange.com/questions/274473/<?php the_permalink() ?>”> <?php the_title(); ?> </a> <?php echo get_the_term_list( get_the_ID(), ‘product_cat’, ”, ‘, ‘ ); ?> </li> <?php endwhile; ?> Note that when you’re inside ‘the loop’ (i.e. between … Read more
You can do this by getting the child categories of that category first, then passing them as an array to your query. $categories=get_categories( array( ‘parent’ => $cat->cat_ID ) ); $cat_list = []; foreach ($categories as $c) { $cat_list[] = $c->term_id; } ref: Get the children of the parent category This won’t/might not work, but it’s … Read more
Looks as though we had mistakenly added a posts per page onto the pre_get_posts filter that was limiting not just the front end, but the backend too. We simply wrapped that code with !is_admin() and we were good to go!
The properties prefixed with category_ or cat_ are there for backwards compatibility. Taxonomies and terms were introduced in WordPress 2.3 (11 years ago) and categories were converted into a taxonomy at that time. Prior to this categories had their own properties (the ones with the aforementioned prefixes). For backwards compatibility, the _make_cat_compat() function is used … Read more
The tag template page began displaying posts for specific tags once I replaced the argument statement with the following, which is great!!: $tags = get_the_tags(); $tag = $tags[0]->name; $args = array( ‘post_type’ => ‘post’, ‘post_status’=>’publish’, ‘category_name’ => ‘NEWS’, ‘tag_slug__and’ => $tag, ‘posts_per_page’ => 2, ‘paged’ => $paged ); However, when I click on a pagination … Read more
10 is the default page length which is taken from the WordPress settings. It’s a little bit hidden but there in the docs for WP Query there’s a parameter posts_per_page which can be set to -1 to get all posts, so you just need to add that to the arguments to pass to WP_Query. (If … Read more
Here’s an updated version of your code that will get posts that have the Post Format Video and that have the same Categories as the current post in the loop. You’ll call wpse_get_video_posts_with_matching_categories() to execute the function. function wpse_get_video_posts_with_matching_categories() { $categories = get_the_category( get_the_ID() ); if ( empty ( $categories ) ) { return; } … Read more
