订单列表WooCommerce基于定制状态的元数据的订单

我正在尝试创建名为“Priority Order”的自定义状态，当产品状态更改为“Priority Order”时，将自动添加post meta调用_priority_list 数字基于多少订单设置为优先级订单，我的问题是如何使用meta创建默认订单列表_priority_list? 这是我当前的代码：

function filter_priority_orders() {
    global $pagenow;
    $qv = &$query->query_vars;

    if ( $pagenow == \'edit.php\' && isset($qv[\'post_status\']) && $qv[\'post_status\'] == \'wc-priority-order\' ) {            
        $query->set(\'meta_key\', \'_priority_list\');
        $query->set(\'order_by\', \'_priority_list\');
    }

    return $query;
}
add_filter( \'pre_get_posts\', \'filter_priority_orders\' );

提前感谢！

function filter_priority_orders($query) { global $pagenow; $qv = $query->query_vars; if ( $pagenow == \'edit.php\' && isset($qv[\'post_status\']) && $qv[\'post_status\'] == \'wc-priority-order\' && isset($qv[\'post_type\']) && $qv[\'post_type\'] == \'shop_order\' ) { $query->set(\'meta_key\', \'_priority_list\'); $query->set(\'orderby\', \'meta_value_num\'); $query->set(\'order\', \'ASC\' ); } return $query; } add_filter( \'pre_get_posts\', \'filter_priority_orders\' );
