You’re using category query for your custom taxonomy. So it won’t work, because there are no categories with such IDs. You should use tax_query instead. // post types query while ( have_posts() ) { the_post(); // getting the categories $categoryIDs = array(); // it’s much nicer than concatenated string $getcategory = get_the_terms($post->ID, ‘custompostnamehere-categories’); foreach($getcategory as … Read more
This is the code that was needed in order to make it show only the posts (that were of a specific custom post type) that matched the same child category (therefore matching all the other categories): <!– other posts –> <?php //this gets the lowest hierarchical child term for current post $categories = get_the_category($post->ID); foreach($categories … Read more
wp_reset_query(); resets the query to the original main query of the page. Therefore, storing the query in another variable is redundant and unnecessary. Updated code: $args = array( ‘cat’ => 15, ‘paged’ => $paged ); $custom_query = new WP_Query( $args ); while ($custom_query -> have_posts()) : $custom_query -> the_post(); endwhile; my_pagination(); //call function wp_reset_query(); //#3. … Read more
Page link functions depend on the value in the $paged global variable. So, we need to update that variable as well as the parameter in the custom query. If we are on a “static” front page, the ‘paged’ query variable should be undefined and the ‘page’ query variable may be defined. If neither query variable … Read more
Two notes beforehand: There is no (unless you created a CPT) post type random_posts. Don’t use query_posts. That being said, the following will do what you want: Just the randomness $args = array( ‘posts_per_page’ => ’10’, ‘orderby’ => ‘rand’ ); $random_posts = get_posts( $args ); foreach( $random_posts as $random_post ) { // do something echo … Read more
You have to query post that has no post format attached: $args = array( ‘post_type’ => ‘post’, ‘tax_query’ => array( array( ‘taxonomy’ => ‘post_format’, ‘field’ => ‘slug’, ‘operator’ => ‘NOT IN’, ‘terms’ => get_terms(‘post_format’) ) ) ); To improve performance you can hardcoding the post format instead of using get_terms to retrieve them: $args = … Read more
Almost all integers in WordPress are treated as strings. If you try to var_dump($post->ID); inside a loop you notice also post id is a string. Normally this is not a problem because of PHP auto type casting feature. This can be a problem, when you do strict comparison, like 1 === $post->ID or in_array(1, $ids, … Read more
Try this: global $wpdb; $num_cat = 6; $query = “SELECT tt.term_taxonomy_id, t.name, COUNT( t.name ), GROUP_CONCAT( p.ID ) , GROUP_CONCAT(m.meta_value) FROM {$wpdb->prefix}term_taxonomy tt NATURAL JOIN {$wpdb->prefix}terms t NATURAL JOIN {$wpdb->prefix}term_relationships tr JOIN {$wpdb->prefix}posts p ON ( tr.object_id = ID ) JOIN {$wpdb->prefix}postmeta m ON ( post_id = ID ) WHERE taxonomy = ‘category’ AND post_type=”post” … Read more
It’s just serialized, in WordPress, you can run maybe_unserialize and get back the variable/array. $crosssells = $wpdb->get_results( “SELECT * FROM $wpdb->postmeta WHERE _crosssell_ids <> ” ” ); $array = maybe_unserialize($crosssells); However, there are built in functions to retrieve posts based on meta information. You can use get_posts to retrieve the posts and get_post_meta to retrieve … Read more
It is all for adding posts into the cache. The usefulness of this is so that get_post( $post_id ) doesn’t result in another hit to the database. This is likely as many of the template functions inside the loop call get_post(). I don’t fully understand the logic for expression for $split_the_query. The limit makes sense … Read more
