无法在admin-ajax.php中使用WC_Order

Question

我试图在admin-ajax.php请求中检索订单信息，但它返回的是没有数据的受保护对象。有没有办法访问它？

我用这个：

$data = new WC_Order($order_id);
var_dump($data);

这在以下内容中运行时起作用：

add_action('woocommerce_order_status_completed', 'send_documents_to_customer');

但我还需要将此作为管理员ajax请求运行：

add_action('wp_ajax_send_documents_to_customer', 'send_documents_to_customer');

但它返回protected：

object(WC_Order)#15861 (14) { ["status_transition":protected]=> bool(false) ["data":protected]=> array(28) { ["parent_id"]=> int(0) ["status"]=> string(0) "" ["currency"]=> string(0) "" ["version"]=>

Answer 1

您可以使用WC Order

中提供的功能获取所有订单数据

Answer 2

原来，$ order_id实际上没有将值传递给admin-ajax.php：

.item { position: absolute; transition: top 1s; }

所以我在下面写了：

function send_documents_to_customer($order_id) {

这可确保始终设置有效值。
