I would do this with SQL query. Doing it in PHP will be a little bit slow, I guess. This function should do the job: function get_categories_from_year($year) { $sql = “select term.* from {$wpdb->terms} term inner join {$wpdb->term_taxonomy} tax on (term.term_id = tax.term_id) inner join {$wpdb->term_relationships} relation on (tax.term_taxonomy_id = relation.term_taxonomy_id) inner join {$wpdb->posts} post … Read more
If all you’re trying to do is to display all post types on the taxonomy archive, then you can easily accomplish that by filtering the query at pre_get_posts. Assuming a taxonomy foobar: function wpse111033_filter_pre_get_posts( $query ) { if ( $query->is_main_query() && $query->is_tax( ‘foobar’ ) ) { $query->set( ‘post_type’, ‘any’ ); } } add_action( ‘pre_get_posts’, ‘wpse111033_filter_pre_get_posts’ … Read more
Yes, you don’t need a custom taxonomy, but a custom post type for courses, and probably a custom taxonomy for courses categories. In WordPress post types are containers for a certain type of information: every information type is a post type. E.g. Posts are a type and Pages are another type. Every post type (container) … Read more
Each term has a term_id, and each has a parent. Child terms of ParentTerm A will have a parent value equal to ParentTerm A‘s term_id, so given the parent term’s ID, you can test each term to see if the parent field matches- $parent_term_id = 42; foreach ( $terms as $term ) { if( $term->parent … Read more
If I understood you right the following is what you need: $term_link = get_term_link( $term, ‘genre1’ ); // if there is no error print the link if( !is_wp_error( $term_link ) ) echo ‘<li><a href=”‘ . $term_link . ‘”>’ . get_the_title() . ‘</a></li>’;
If your post have always children and parent category you can just skip the query for parent using continue: foreach( $terms as $term ) : echo ‘<h3>’. $term->name. ‘</h3>’; if ( $term->parent == 0 ) continue; // rest of your code here Problem whith this is only that if a post has a parent term, … Read more
tax_query is used to get the posts associated with certain taxonomy. {tax} (string) – use taxonomy slug. Deprecated as of Version 3.1 in favor of ‘tax_query’. tax_query (array) – use taxonomy parameters (available with Version 3.1). taxonomy (string) – Taxonomy. field (string) – Select taxonomy term by (‘id’ or ‘slug’) terms (int/string/array) – Taxonomy term(s). … Read more
After about 100 different tries, I got it to work. Not sure if there is a better way, but it works. $term_slug = get_query_var( ‘term’ ); $taxonomyName = get_query_var( ‘taxonomy’ ); $current_term = get_term_by( ‘slug’, $term_slug, $taxonomyName ); $args = array( ‘post_type’ => ‘clients’, ‘posts_per_page’ => -1, ‘orderby’ => ‘title’, ‘order’ => ‘ASC’, ‘tax_query’=>array( array( … Read more
What you need is set the show_option_none to a string easily recognizable and then add the result of wp_list_categories to the content only if it it does not contain that string.. So your foreach loop shoul look somethinlg like foreach( $taxonomies as $taxonomy ) { $args = array( ‘orderby’ => ‘name’, ‘echo’ => false, ‘taxonomy’ … Read more
That is a very broken Loop. The results of a new WP_Query is not a simple array that you can foreach over. It is far more complicated than that. Try var_dump($work_galleries);. Fortunately, WP_Query provides methods to make looping easy. $work_galleries = new WP_Query($args); if ($work_galleries->have_posts()) { while ($work_galleries->have_posts()) { // this replaces foreach $work_galleries->the_post(); // … Read more
