The wpse244577_list_terms() function below uses wp_list_categories() to do the heavy lifting, then modifies the results so that the terms are in reverse order of the hierarchy. Place this code in a plugin or your theme’s functions.php file: /** * Lists term links for a taxonomy in reverse order of hierarchy * * Based on https://developer.wordpress.org/reference/functions/wp_list_categories/#comment-1169 … Read more
First of all, in WordPress here the best option to solve my problem is using Custom Post Types and Custom Taxonomies. To do that, I’ve created a file named “my_custom_posts.php” and put it inside the theme’s root folder. Then I’ve included this file in my “functions.php” using require(‘my_custom_posts.php’); You can also put your custom post … Read more
I made it ! This is the final code that returns a hierarchical array based on taxonomy. public function return_all_tax_objects() { $obj_term_posts = array(); // GET FLAT LIST OF TERMS BELONGING TO THE POST foreach ( $this->return_object_terms() as $obj_term ) { // IF TERM HAS A PARENT if ( $obj_term->parent ) { unset ( $keys … Read more
Since wp_set_post_terms() does not accept hierarchy for it, you will first have to check if terms exist already, create them using wp_insert_term() if not and only then assign to post. Note that there had been (don’t know current state) some cache related bugs with doing such things on the fly, see Inserting terms in an … Read more
I believe you want get_queried_object. If you have set your static front page and blog page from wp-admin->Settings->Reading then get_queried_object will give you information about the page you chose rather than about the posts in the Loop. Be aware that get_queried_object will return very different types of information depending on the kind of page you … Read more
You can use the post_parent__not_in parameter: $args = array( ‘post_type’ => ‘cpt’, ‘post_parent__not_in’ => array( 0 ) ); $query = new WP_Query( $args ); to retrieve child posts of type cpt. The generated SQL will then include this part: wp_posts.post_parent NOT IN (0)
Just clarifying, what was pointed out by Parst with a working example of a custom taxonomy registration code: $labels = array( ‘name’ => _x( ‘Issue numbers’, ‘taxonomy general name’, ‘sascha_setup_post_type’ ), ‘singular_name’ => _x( ‘Issue number’, ‘taxonomy singular name’, ‘sascha_setup_post_type’ ), ‘search_items’ => __( ‘Search issues’, ‘sascha_setup_post_type’ ), ‘all_items’ => __( ‘All issue numbers’, ‘sascha_setup_post_type’ … Read more
There is no such thing as “Sub Posts” in WordPress already built in. But it could be possible that you create a plugin that is introducing “Sub Posts” in the style you describe them. Technically you’re not talking about subposts but about the URL-Layout. So in WordPress you add an endpoint (“changelog”) that you can … Read more
I was able to resolve this with the following code which generates rewrite_rules for each subcategory, which is preferred during matching since it’s more specific: function wpse_291143_generate_taxonomy_rewrite_rules( $wp_rewrite ) { global $wp_rewrite; $base = “shop”; $rules = array(); $terms = get_terms( array( ‘taxonomy’ => ‘product_cat’, ‘hide_empty’ => false )); foreach($terms as $term) { $term_children = … Read more
Finally, I solved it myself. Here is the solution: In functions.php: function show_all_children($parent_id, $post_id, $current_level) { $top_parents = array(); $top_parents = get_post_ancestors($post_id); $top_parents[] = $post_id; $children = get_posts( array( ‘post_type’ => ‘page’ , ‘posts_per_page’ => -1 , ‘post_parent’ => $parent_id , ‘order_by’ => ‘title’ , ‘order’ => ‘ASC’ )); if (empty($children)) return; echo ‘<ul class=”children … Read more
