3.0版以上的WOOCOMMERCE订单
自Woocommerce大型主要更新3.0+以来，事情已经发生了很多变化：
- 对于
WC_Order
对象，无法像以前一样直接访问属性，并且会引发一些错误。 - 现在，对象实例需要使用new
WC_Order
以及WC_Abstract_Order
getter和setter方法WC_Order
。 - 此外，还有一些用于订购商品的新类：
WC_Order_Item
类，WC_Order_Item_Product
class- _
WC_Order_Item_Tax
class - _
WC_Order_Item_Shipping
class - _
WC_Order_Item_Coupon
class - _
WC_Order_Item_Fee
class
因此，无法像以前那样在 foreach
循环中访问Orderitems属性，而必须使用这些特定的getter和setter方法]。
使用一些 WC_Order
和 WC_Abstract_Order
方法（示例）：
// Get an instance of the WC_Order object (same as before)$order = wc_get_order( $order_id );$order_id = $order->get_id(); // Get the order ID$parent_id = $order->get_parent_id(); // Get the parent order ID (for subscriptions…)$user_id = $order->get_user_id(); // Get the costumer ID$user = $order->get_user(); // Get the WP_User object$order_status = $order->get_status(); // Get the order status $currency = $order->get_currency(); // Get the currency used $payment_method = $order->get_payment_method(); // Get the payment method ID$payment_title = $order->get_payment_method_title(); // Get the payment method title$date_created = $order->get_date_created(); // Get date created (WC_DateTime object)$date_modified = $order->get_date_modified(); // Get date modified (WC_DateTime object)$billing_country = $order->get_billing_country(); // Customer billing country// ... and so on ...
获取并访问订单数据属性（在值数组中）：
// Get an instance of the WC_Order object$order = wc_get_order( $order_id );$order_data = $order->get_data(); // The Order data$order_id = $order_data['id'];$order_parent_id = $order_data['parent_id'];$order_status = $order_data['status'];$order_currency = $order_data['currency'];$order_version = $order_data['version'];$order_payment_method = $order_data['payment_method'];$order_payment_method_title = $order_data['payment_method_title'];$order_payment_method = $order_data['payment_method'];$order_payment_method = $order_data['payment_method'];## Creation and modified WC_DateTime Object date string ##// Using a formated date ( with php date() function as method)$order_date_created = $order_data['date_created']->date('Y-m-d H:i:s');$order_date_modified = $order_data['date_modified']->date('Y-m-d H:i:s');// Using a timestamp ( with php getTimestamp() function as method)$order_timestamp_created = $order_data['date_created']->getTimestamp();$order_timestamp_modified = $order_data['date_modified']->getTimestamp();$order_discount_total = $order_data['discount_total'];$order_discount_tax = $order_data['discount_tax'];$order_shipping_total = $order_data['shipping_total'];$order_shipping_tax = $order_data['shipping_tax'];$order_total = $order_data['cart_tax'];$order_total_tax = $order_data['total_tax'];$order_customer_id = $order_data['customer_id']; // ... and so on## BILLING INFORMATION:$order_billing_first_name = $order_data['billing']['first_name'];$order_billing_last_name = $order_data['billing']['last_name'];$order_billing_company = $order_data['billing']['company'];$order_billing_address_1 = $order_data['billing']['address_1'];$order_billing_address_2 = $order_data['billing']['address_2'];$order_billing_city = $order_data['billing']['city'];$order_billing_state = $order_data['billing']['state'];$order_billing_postpre = $order_data['billing']['postpre'];$order_billing_country = $order_data['billing']['country'];$order_billing_email = $order_data['billing']['email'];$order_billing_phone = $order_data['billing']['phone'];## SHIPPING INFORMATION:$order_shipping_first_name = $order_data['shipping']['first_name'];$order_shipping_last_name = $order_data['shipping']['last_name'];$order_shipping_company = $order_data['shipping']['company'];$order_shipping_address_1 = $order_data['shipping']['address_1'];$order_shipping_address_2 = $order_data['shipping']['address_2'];$order_shipping_city = $order_data['shipping']['city'];$order_shipping_state = $order_data['shipping']['state'];$order_shipping_postpre = $order_data['shipping']['postpre'];$order_shipping_country = $order_data['shipping']['country'];获取订单项并使用 WC_Order_Item_Product
和 WC_Order_Item
方法访问数据：
// Get an instance of the WC_Order object$order = wc_get_order($order_id);// Iterating through each WC_Order_Item_Product objectsforeach ($order->get_items() as $item_key => $item ): ## Using WC_Order_Item methods ## // Item ID is directly accessible from the $item_key in the foreach loop or $item_id = $item->get_id(); ## Using WC_Order_Item_Product methods ## $product = $item->get_product(); // Get the WC_Product object $product_id = $item->get_product_id(); // the Product id $variation_id = $item->get_variation_id(); // the Variation id $item_type = $item->get_type(); // Type of the order item ("line_item") $item_name = $item->get_name(); // Name of the product $quantity = $item->get_quantity(); $tax_class = $item->get_tax_class(); $line_subtotal = $item->get_subtotal(); // Line subtotal (non discounted) $line_subtotal_tax = $item->get_subtotal_tax(); // Line subtotal tax (non discounted) $line_total = $item->get_total(); // Line total (discounted) $line_total_tax = $item->get_total_tax(); // Line total tax (discounted) ## Access Order Items data properties (in an array of values) ## $item_data = $item->get_data(); $product_name = $item_data['name']; $product_id = $item_data['product_id']; $variation_id = $item_data['variation_id']; $quantity = $item_data['quantity']; $tax_class = $item_data['tax_class']; $line_subtotal = $item_data['subtotal']; $line_subtotal_tax = $item_data['subtotal_tax']; $line_total = $item_data['total']; $line_total_tax = $item_data['total_tax']; // Get data from The WC_product object using methods (examples) $product = $item->get_product(); // Get the WC_Product object $product_type = $product->get_type(); $product_sku = $product->get_sku(); $product_price = $product->get_price(); $stock_quantity = $product->get_stock_quantity();endforeach;因此，使用
get_data()method可以使我们访问受保护的数据（关联数组模式）…
