Question

我最近试图用挂钩修改我的所有运费以应用折扣。

这是我的代码：

add_filter( 'woocommerce_package_rates', 'woocommerce_package_rates' );
function woocommerce_package_rates( $rates ) {
    $user_id = get_current_user_id();
    if ( ! wc_memberships_is_user_active_member( $user_id, 'silver' ) ) { return $rates; }
    $discount_amount = 30; // 30%

    foreach($rates as $key => $rate ) {
        $rates[$key]->cost = $rates[$key]->cost - ( $rates[$key]->cost * ( $discount_amount/100 ) );
    }

    return $rates;
}

但还有一步就是税收！我的税收错了。
例如，我的运费为3$。有了折扣，它现在是2,10$。

我为2$和发货2.10$购买了一件商品。我得到1美元的税（因为3美元的运费。看起来他没有做出改变），通常它是0.82$。

我需要什么才能获得正确的税收计算？

更新与运费方法的税费计算相关

您的代码存在一些小错误，而您错过了计税折扣。我稍微重新审视了你的代码，你应该试试这个：

add_filter( 'woocommerce_package_rates', 'conditional_shipping_discount', 10, 2 );
function conditional_shipping_discount( $rates, $packages ) {

    $user_id = get_current_user_id();
    if ( ! wc_memberships_is_user_active_member( $user_id, 'silver' ) ) return $rates;

    $percent = 30; // 30%
    $discount = 1 - ($percent / 100);

    foreach($rates as $rate_key => $rate_values ) {
        // Get original cost
        $original_cost = $rates[$rate_id]->cost;
        // Calculate the discounted rate cost
        $new_cost = $original_cost * $discount;
        // Set the discounted rate cost
        $rates[$rate_key]->cost = number_format(new_cost, 2);
        // calculate the conversion rate (for taxes)
        $conversion_rate = $new_cost / $original_cost;

        // Taxes rate cost (if enabled)
        $taxes = array();
        foreach ($rates[$rate_key]->taxes as $key => $tax){
            if( $tax > 0 ){ // set the new tax cost
                // set the new line tax cost in the taxes array
                $taxes[$key] = number_format( $tax * $conversion_rate, 2 );
            }
        }
        // Set the new taxes costs
        $rates[$rate_key]->taxes = $taxes
    }
    return $rates;
}

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试并有效。

您需要刷新送货缓存：
  1）首先，此代码已保存在function.php文件中。
  2）在运输设置中，输入运输区域并禁用运输方式和“保存”。然后重新启用送货方式和“保存”。 你已经完成了。

@LoicTheAztec代码下面，没有错误：

add_filter( 'woocommerce_package_rates', 'conditional_shipping_discount', 10, 2 );
    function conditional_shipping_discount( $rates, $packages ) {

    $user_id = get_current_user_id();
    if ( ! wc_memberships_is_user_active_member( $user_id, 'silver' ) ) return $rates;

    $percent = 30; // 30%
    $discount = 1 - ($percent / 100);

    foreach($rates as $rate_key => $rate_values ) {
        // Get original cost
        $original_cost = $rates[$rate_key]->cost;
        // Calculate the discounted rate cost
        $new_cost = $original_cost * $discount;
        // Set the discounted rate cost
        $rates[$rate_key]->cost = number_format($new_cost, 2);
        // calculate the conversion rate (for taxes)
        $conversion_rate = $new_cost / $original_cost;

        // Taxes rate cost (if enabled)
        $taxes = array();
        foreach ($rates[$rate_key]->taxes as $key => $tax){
            if( $tax > 0 ){ // set the new tax cost
                // set the new line tax cost in the taxes array
                $taxes[$key] = number_format( $tax * $conversion_rate, 2 );
            }
        }
        // Set the new taxes costs
        $rates[$rate_key]->taxes = $taxes;
    }
    return $rates;
}
