将新创建的拆分订单从 WooCommerce 中的原始订单链接到客户

Question

我正在使用一段漂亮的代码来拆分订单（如果它包含任何缺货产品） 拆分 WooCommerce 订单并创建一个新订单（如果原始订单有缺货产品） 答案代码。 这对于在结账时创建第二个订单非常有效，但新订单不会链接到用户，相反，订单客户是访客。

如何将新创建的订单Customer设置为创建订单时的用户？

function sa_woocommerce_checkout_order_on_backorder( $order_id, $posted_data, $order ) {
    // Initialize
    $check_for_back_orders = false;

    // Loop through order items
    foreach ( $order->get_items() as $item_key => $item ) {
        // Get product
        $product = $item->get_product();

        // Product is on backorder
        if ( $product->is_on_backorder() ) {
            // Will only be executed once if the order contains back orders
            if ( $check_for_back_orders == false ) {
                $check_for_back_orders = true;

                // Create new order with backorders
                $backorder_order = wc_create_order();
            }

            // Add product to 'backorder' order
            $backorder_order->add_product( $product, $item['quantity'] );

            // Delete item from original order
            $order->remove_item( $item->get_id() );
        }
    }

    // If current order contains backorders, retrieve the necessary data from the existing order and apply it in the new order
    if ( $check_for_back_orders ) {
        // Recalculate and save original order
        $order->calculate_totals();
        $order->save();
        
        // Obtain necessary information
        // Get address
        $address = array(
            'first_name' => $order->get_billing_first_name(),
            'last_name'  => $order->get_billing_last_name(),
            'email'      => $order->get_billing_email(),
            'phone'      => $order->get_billing_phone(),
            'address_1'  => $order->get_billing_address_1(),
            'address_2'  => $order->get_billing_address_2(),
            'city'       => $order->get_billing_city(),
            'state'      => $order->get_billing_state(),
            'postcode'   => $order->get_billing_postcode(),
            'country'    => $order->get_billing_country()
        );

        // Get shipping
        $shipping = array(
            'first_name' => $order->get_shipping_first_name(),
            'last_name'  => $order->get_shipping_last_name(),
            'address_1'  => $order->get_shipping_address_1(),
            'address_2'  => $order->get_shipping_address_2(),
            'city'       => $order->get_shipping_city(),
            'state'      => $order->get_shipping_state(),
            'postcode'   => $order->get_shipping_postcode(),
            'country'    => $order->get_shipping_country()
        );
        
        // Get order currency
        $currency = $order->get_currency();

        // Get order payment method
        $payment_gateway = $order->get_payment_method();
        
        // Required information has been obtained, assign it to the 'backorder' order
        // Set address
        $backorder_order->set_address( $address, 'billing' );
        $backorder_order->set_address( $shipping, 'shipping' );

        // Set the correct currency and payment gateway
        $backorder_order->set_currency( $currency );
        $backorder_order->set_payment_method( $payment_gateway );

        // Calculate totals
        $backorder_order->calculate_totals();

        // Set order note with original ID
        $backorder_order->add_order_note( 'Automated backorder. Created from the original order ID: ' . $order_id );

        // Optional: give the new 'backorder' order the correct status
        $backorder_order->update_status( 'processing' );
    }
}
add_action( 'woocommerce_checkout_order_processed', 'sa_woocommerce_checkout_order_on_backorder', 10, 3 );

Answer 1

在

wc_create_order()

功能中，您可以定义客户ID（和父订单），例如：

// Create new order with backorders
$backorder_order = wc_create_order( array(
    'customer_id' => $order->get_customer_id(),
    'parent'      => $order_id,
) );

这样创建的订单将链接到用户，因此不再是“访客”。

我还简化了您当前的代码。请尝试以下方法：

add_action( 'woocommerce_checkout_order_processed', 'split_checkout_order_with_backorder_items', 10, 3 );
function split_checkout_order_with_backorder_items( $order_id, $posted_data, $order ) {
    $has_backorder_items = false; // Initialize

    // Loop through order items
    foreach ( $order->get_items() as $item_id => $item ) {
        $product = $item->get_product();
        // Is item is on backorder?
        if ( $product->is_on_backorder() ) {
            // Create new order with the backorder item
            $sub_order = wc_create_order( array(
                'customer_id' => $order->get_customer_id(),
                'parent'      => $order_id,
            ));

            $sub_order->add_product( $product, $item->get_quantity() ); // Add item on newly created order
            $order->remove_item( $item_id ); // Remove item from current Order

            $has_backorder_items = true; 

            $sub_order->set_currency( $order->get_currency() );
            $sub_order->set_payment_method( $order->get_payment_method() );

            $sub_order->set_address( $order->get_address('billing'), 'billing' );
            $sub_order->set_address( $order->get_address('shipping'), 'shipping' );

            $sub_order->add_order_note( sprintf( __('Automated backorder. Created from the original order ID: %d'), $order_id ) );

            // Calculate totals, set status and save
            $sub_order->calculate_totals();
            $sub_order->update_status( 'processing' );
        }
    }

    // If current order had backordered items
    if ( $has_backorder_items ) {
        // Recalculate and save current order
        $order->calculate_totals();
        $order->save();
    }
}

代码位于子主题的functions.php 文件中（或插件中）。已测试并有效。
