计算 WooCommerce 中现有订单的运费 methods/rates

Question

我基本上是在尝试复制购物车页面上的功能，用户可以在其中添加他们的 zip code 并计算可用的运费，但我试图从后端从内部进行一个已经创建的订单。

我找不到直接从 WC_Order 实例执行此操作的方法，所以我的下一个最佳选择是清除购物车会话，将订单中的所有项目添加到购物车会话，然后尝试计算它。

这是我目前所拥有的。我一直纠结于如何计算整个订单的费率。

$order_id       = isset($_POST['order_id'])?$_POST['order_id']:0;
$country        = isset($_POST['country'])?$_POST['country']:0;
$state          = isset($_POST['state'])?$_POST['state']:0;
$postcode       = isset($_POST['postcode'])?$_POST['postcode']:0;
$city           = isset($_POST['city'])?$_POST['country']:0;
$order          = wc_get_order( $order_id );
$order_items    = $order->get_items();

// Don't know if this would save country of logged in user, or only create a temporary guest user session which is what I'd need
if ( $country != '' ) {
    WC()->customer->set_billing_location( $country, $state, $postcode, $city );
    WC()->customer->set_shipping_location( $country, $state, $postcode, $city );
} else {
    WC()->customer->set_billing_address_to_base();
    WC()->customer->set_shipping_address_to_base();
}

// Remove all current items from cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
    WC()->cart->empty_cart();
}

// Add all items from the order to the cart
foreach ($order_items as $order_item) {
    WC()->cart->add_to_cart($order_item['product_id'], $order_item['qty']);
}

$totals = WC()->shipping->get_packages();

// $totals returns rates but I believe it is per each "package". It's not a cumulative rate like the cart page shows.

Answer 1

尝试使用：

// Calculate totals
WC()->cart->calculate_totals();
WC()->cart->calculate_shipping();

// Retrieve the shipping total
$shipping_total = WC()->cart->get_shipping_total();

WC_Cart class 应该具有重新创建您可能需要的任何购物车功能所需的所有方法。我建议您通读并熟悉此处的 class 定义...

好的，多亏了@mujuonly，我才弄明白了。

以下是获取所有计算的运费的方法，与在购物车页面上显示的方式相同。

// Post variables
$order_id   = isset($_POST['order_id'])?$_POST['order_id']:0;
$country    = isset($_POST['country'])?$_POST['country']:0;
$state      = isset($_POST['state'])?$_POST['state']:0;
$postcode   = isset($_POST['postcode'])?$_POST['postcode']:0;
$city       = isset($_POST['city'])?$_POST['city']:0;

// Order and order items
$order          = wc_get_order( $order_id );
$order_items    = $order->get_items();

// Reset shipping first
WC()->shipping()->reset_shipping();

// Set correct temporary location
if ( $country != '' ) {
    WC()->customer->set_billing_location( $country, $state, $postcode, $city );
    WC()->customer->set_shipping_location( $country, $state, $postcode, $city );
} else {
    WC()->customer->set_billing_address_to_base();
    WC()->customer->set_shipping_address_to_base();
}

// Remove all current items from cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
    WC()->cart->empty_cart();
}

// Add all items to cart
foreach ($order_items as $order_item) {
    WC()->cart->add_to_cart($order_item['product_id'], $order_item['qty']);
}

// Calculate shipping
$packages = WC()->cart->get_shipping_packages();
$shipping = WC()->shipping->calculate_shipping($packages);
$available_methods = WC()->shipping->get_packages();

$available_methods[0]['rates'] 将具有订单内产品在该位置可用的所有运费。

Answer 3

注意：这不是答案，我无法发表评论，因此我写在这里。就我而言，接受的答案有问题：

如果客户已经在购物车中添加了一些商品，它们将会丢失，因为以下代码行：

WC()->cart->empty_cart()

相反，购物车中装满了过去订单中的商品。

到目前为止，似乎有必要使用购物车来正确计算运输包裹。如果是这样，我可以创建当前购物车的克隆然后计算运输包裹吗？我不想在进行此计算时影响客户的原始购物车。
