我想计算 woocommerce 中当前产品价格的百分比(%)。 对我来说最好的是能够将代码添加到每个产品中，因为不同的产品会有不同的通行费百分比。 所以，如果有一个函数或 Javascript 可以做到这一点那就太棒了..
抱歉，但我在任何地方都找不到任何相关代码。
即
“如果您订购此产品，您必须支付$2的通行费”
公式：100 * 0,02
谢谢大家！
简单的 Javascript 解决方案不足以解决这个问题。在计算应付总金额之前，您需要更新购物车商品价格。否则您的客户根本不会被收取费用。
我写了一个简单的插件来解决这个问题。这是代码-

将此代码保存在扩展名为
.phppluginsfunctions.php您将在产品编辑页面中看到一个新字段：此产品的收费。输入百分比金额，瞧。您会在产品类别页面、单个产品页面、购物车页面和结帐页面中看到一些通知。当然，这个金额将与产品价格相加。 如果您遇到任何困难，请发表评论。
您在寻找这样的东西吗？
const tollTiers = {
2: .02,
4: .04,
6: .06
};
const products = [
{name: 'Widget', toll: tollTiers[2], price: 100 },
{name: 'Gadget', toll: tollTiers[4], price: 50 },
{name: 'Cog', toll: tollTiers[6], price: 200 },
];
const list = document.querySelector('#products');
products.forEach((product) => {
const price = product.price;
const fee = price * product.toll;
const total = price + fee;
const li = document.createElement('li');
const text = document.createTextNode(
`${product.name} - $${price} + $${fee} (${product.toll * 100}%) toll = $${total}.`
);
li.appendChild(text);
list.appendChild(li);
});<ul id="products"></ul>要在档案页面和单个产品页面上显示动态计算的通行费，请尝试：
add_action('woocommerce_after_shop_loop_item_title','price_custom_label', 15 ); // Archives pages
add_action('woocommerce_single_product_summary','price_custom_label', 15 ); // single product pages
function price_custom_label(){
global $product;
$toll_fee = wc_price($product->get_price() * 2 / 100);
$text = sprintf( __( 'You must pay a toll fee of %s if you order this product', 'woocommerce' ), $toll_fee );
echo '<p>'. $text . '</p>';

已测试且有效。
您应该需要对其进行调整并设计其样式。
