You should hook into save_post and set the categories using wp_set_object_terms(): // Add an action to run on post save add_action( ‘save_post’, ‘set_genre_on_save’ ); function set_genre_on_save( $post_id ){ // Check the post type if (is_single(‘tvseries’)) { // Get the custom field data $custom_field_data = get_post_custom( $post_id ); // Check if there is any genres entered … Read more

So, the way to reliably check for the existence of … Read more
Use added_post_meta and update_post_meta with the $post_id. For extended properties see this post and this for more image functions. add_action(‘added_post_meta’, ‘wpse_20151218_after_post_meta’, 10, 4); function wpse_20151218_after_post_meta($meta_id, $post_id, $meta_key, $meta_value) { // _wp_attachment_metadata added if($meta_key === ‘_wp_attachment_metadata’) { // Add Custom Field update_post_meta($post_id, ‘_example_meta_key’, ‘ex087659bh’); // _wp_attached_file // _wp_attachment_metadata (serialized) // _wp_attachment_image_alt // _example_meta_key $attachment_meta = get_post_meta($post_id); … Read more

I wonder if you mean this kind of loop: $total_views = 0; $post_ids = [2, 3, 7, 53, 75]; foreach( $post_ids as $post_id ) { $total_views += (int) get_post_meta( $post_id, ‘post_views’, true ); } to calculate the total sum.
