我本质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
内容并计算可用的运费,但我试图从后端从已创建的订单中执行此操作。
我找不到直接从WC_Order
实例中执行此操作的方法,因此我拥有的下一个最好的方法是清除购物车会话,将订单中的所有项目添加到购物车会话,然后尝试计算它。
这是我到目前为止所拥有的。我总是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.
