php – 在Woocommerce 3中以编程方式在订单中添加送货

我一直在尝试通过Woocommerce以编程方式设置运费(每个订单)的众多解决方案.我没有运气

我试过覆盖该项的元值：

            update_post_Meta( $woo_order_id, '_order_shipping', $new_ship_price );

也试过这个问题[问题/答案] [1]

                    $item_ship = new WC_Order_Item_Shipping();

                    $item_ship->set_name( "flat_rate" );
                    $item_ship->set_amount( $new_ship_price );
                    $item_ship->set_tax_class( '' );
                    $item_ship->set_tax_status( 'none' );


                    // Add Shipping item to the order
                    $order->add_item( $item_ship );

但似乎都不起作用.
任何指针都非常受欢迎.

解决方法:

要在Woocommerce 3中处理此问题,请使用以下内容(来自WC_Order Order对象$order)：

## ------------- ADD SHIPPING PROCESS ---------------- ##

// Get the customer country code
$country_code = $order->get_shipping_country();

// Set the array for tax calculations
$calculate_tax_for = array(
    'country' => $country_code,
    'state' => '', // Can be set (optional)
    'postcode' => '', // Can be set (optional)
    'city' => '', // Can be set (optional)
);

// Optionally, set a total shipping amount
$new_ship_price = 5.10;

// Get a new instance of the WC_Order_Item_Shipping Object
$item = new WC_Order_Item_Shipping();

$item->set_method_title( "Flat rate" );
$item->set_method_id( "flat_rate:14" ); // set an existing Shipping method rate ID
$item->set_total( $new_ship_price ); // (optional)
$item->calculate_taxes($calculate_tax_for);

$order->add_item( $item );

$order->calculate_totals();

$order->update_status('on-hold');

// $order->save(); // If you don't update the order status
