Wordpress - 以编程方式将购物车运送总额更改为任何自定义值

Question

我使用Wordpress插件设置了一个虚拟WooCommerce网站。

我还有一个虚拟产品：“Cool Watch”。

我的目标非常简单。用户在购物车中添加一个“Cool Watch”后。我想change将shipping total custom value改为programmatically，例如：67.89 USD。

我需要做些什么才能获得Shipping total: Free!？

现在我得到：<? if (!function_exists("echoc")) { function echoc($data) { echo "\n<pre>\n"; print_r($data); echo "</pre>\n"; } } $cart_items = $woocommerce->cart->get_cart(); echoc($cart_items); $shipping_total = $woocommerce->cart->get_cart_shipping_total(); echoc("Shipping total: ".$shipping_total); ?>

这里我给你一些当前情况的背景信息：

我的购物车上有一个“酷手表”。

使用此代码：

Array
(
    [c74d97b01eae257e44aa9d5bade97baf] => Array
        (
            [product_id] => 16

            [variation] => Array
                (

Shipping total: Free!

我明白了：

minimumInteritemSpacing = 0

Answer 1

嘿，这应该这样做：

$cart = $woocommerce->cart ;
$cart->shipping_total = "what ever u want"

shipping_total是Cart Class的公共属性 https://docs.woocommerce.com/wc-apidocs/class-WC_Cart.html

Answer 2

add_action('woocommerce_calculate_totals', 'calculate_totals', 10, 1);

function calculate_totals($totals){
//your code
// return your own value
}
