I don’t see anything particularly wrong with it, although I’d probably write the loop like this: $featuredImage=””; foreach ( $familyTree as $family_postid ) { if ( has_post_thumbnail( $family_postid ) ) { $featuredImage = get_the_post_thumbnail( $family_postid, ‘full’ ); break; } } A bit simpler to understand and eliminates the use of the counter and boolean found … Read more
There is indeed a much simpler way to do this. First, to get the child category, just check the value of each category’s parent. If it’s a top-level category, the parent will be 0. So the child category will pass the test if( 0 != $category->parent ): $categories = get_the_category(); foreach( $categories as $category ){ … Read more
Actually <option> field doesn’t work with any CSS. So WordPress Developers/Designers did a simple yet nice trick for the nesting layout for <option> fields. Actually in your inspection you missed something there: <select name=”page_id” id=”page_id”> <option value=”1″ class=”level-0″>Level 0</option> <option value=”2″ class=”level-1″> Level 1</option> <option value=”3″ class=”level-1″> Level 1</option> <option value=”4″ class=”level-2″> Level 2</option> <option value=”5″ class=”level-3″> Level 3</option> … Read more
Try something like this: <?php $parent_terms = get_terms( ‘name_of_your_taxonomy’, array( ‘parent’ => 0, ) ); foreach ( $parent_terms as $parent_term ) { $child_terms = get_terms( ‘name_of_your_taxonomy’ array( ‘child_of’ => $parent_term->term_id, ) ); foreach ( $child_terms as $child_term ) { $args = array( ‘post_type’ => ‘product’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘name_of_your_taxonomy’, ‘field’ => ‘slug’, … Read more
EDIT According to the OP, this question/answers solved the issue ORIGINAL ANSWER the_post_navigation(), right down to its very core, uses get_adjacent_post() to return and display the next and previous post to the currently viewed post. By default, these adjacent posts are returned by post date. We can alter that by filtering the relevant ORDERBY clause … Read more
Use get_the_terms to fetch the post’s term, then use get_ancestors to get an array of that term’s parent IDs. $tax = ‘category’; $terms = get_the_terms( get_the_ID(), $tax ); if( $terms && ! is_wp_error( $terms ) ){ // check for and output any ancestors $ancestors = array_reverse(get_ancestors( $terms[0]->term_id, $tax )); if( $ancestors ){ foreach( $ancestors as … Read more
You could create a customised ‘landing page’ using a template file? Creating category-internal.php with custom layout would display content at the /category/internal/ url. Here is some more info: https://codex.wordpress.org/Category_Templates http://www.wpbeginner.com/wp-themes/how-to-create-category-templates-in-wordpress/
I love a good challenge! The function here: function get_post_categories_sorted ( $post_id ){ $terms = wp_get_post_terms( $post_id, ‘category’ ); $sorted_terms = []; foreach( $terms as $term ){ $depth = count( get_ancestors( $term->term_id, ‘category’ ) ); if( ! array_key_exists( $depth, $sorted_terms ) ){ $sorted_terms[$depth] = []; } $sorted_terms[$depth][] = $term; } return $sorted_terms; } will give … Read more
Figured a simple pre_get_posts would do the trick, It will, you just need to query posts that have a parent of 0. Assuming your taxonomy slug/name is literally just region: function wpse_286405_parents_only( $query ) { if ( ! is_admin() && $query->is_tax( ‘region’ ) ) { $query->set( ‘post_parent’, 0 ); } } add_action( ‘pre_get_posts’, ‘wpse_286405_parents_only’ );
No, it will not. It changes just the interface in the post editor: you get the page attributes box to select a parent. All existing post have already a value for the parent: 0. You can find it in the post_parent property of each post. The only thing that changes now is the ability to … Read more
