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
get_terms function will return an array of object. Each of them has term_id field which contains id of a term. Just use it instead of slug and you will have what you need: <?php $terms = get_terms(“ratios”); if ( $count($terms) > 0 ){ foreach ( $terms as $term ) { echo “<option value=”” . $term->term_id … Read more

It is possible if you shape your meta query to look for the serialized string like this, assuming your array value is always an integer: $params = array( ‘meta_query’ => array( array( ‘key’ => ‘mediSHOP_product_extras’, ‘value’ => ‘s:11:”is_featured”;i:1;’, ‘compare’ => ‘LIKE’ ) ) ); $query = new \WP_Query( $params ); If the array value is … Read more
You must read custom field themeOps first, update index option3 in array and then save/update whole array. $kisiArray = get_post_meta( $post_id, ‘themeOps’ ); $kisiArray[‘option3’] = ‘peach’; update_post_meta( $post_id, ‘themeOps’, $kisiArray ); Update (sort by custom field) $args = array( ‘post_type’ => ‘post’, ‘meta_key’ => ‘themeOps_option3’, ‘orderby’ => ‘meta_value_num’, ‘order’ => ‘ASC’, ); $query = new … Read more
