post__in for get_posts with a dynamic array
Here’s one way by using wpdb::get_col() and fetch the id column: $pids = $wpdb->get_col( “SELECT id FROM my_table” ); We could then clean it by integer convert each id with: $pids = wp_parse_id_list( $pids ); Just note the different max value for intval(), depending on 32 or 64 bits systems.
