php - 在 woocommerce 结账时添加自定义税值

Question

我想在 woocommerce 结帐页面添加自定义百分比值，但我只想为瑞士国家/地区显示它并为其他国家/地区隐藏它。现在我有了正确的代码，但问题是当用户选择瑞士时我无法显示它。这是一个代码所以请帮我看看我在这里做错了什么

//Add tax for CH country
add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge' );
function woocommerce_custom_surcharge() {
global $woocommerce;

if ( WC()->customer->get_shipping_country('CH') )
    return;

    $percentage = 0.08;
    $taxes = array_sum($woocommerce->cart->taxes);
    $surcharge = ( $woocommerce->cart->cart_contents_total + $woocommerce->cart->shipping_total ) * $percentage;   
    // Make sure that you return false here.  We can't double tax people!
    $woocommerce->cart->add_fee( 'TAX', $surcharge, false, '' );

}

我确定我在这里做错了:

if ( WC()->customer->get_shipping_country('CH') )

感谢帮助

WC_Customer get_shipping_country() 不接受任何国家代码因为您正在获取国家代码。所以你需要在你的代码条件中进行不同的设置。

此外，由于您的 Hook 函数已经将 WC_Cart 对象作为参数，因此您不需要全局 $woocommerce 和 $woocommerce->cart...

因此您重新访问的代码应该是:

// Add tax for Swiss country
add_action( 'woocommerce_cart_calculate_fees','custom_tax_surcharge_for_swiss', 10, 1 );
function custom_tax_surcharge_for_swiss( $cart ) {
    if ( is_admin() && ! defined('DOING_AJAX') ) return;

    // Only for Swiss country (if not we exit)
    if ( 'CH' != WC()->customer->get_shipping_country() ) return;

    $percent = 8;
    # $taxes = array_sum( $cart->taxes ); // <=== This is not used in your function

    // Calculation
    $surcharge = ( $cart->cart_contents_total + $cart->shipping_total ) * $percent / 100;

    // Add the fee (tax third argument disabled: false)
    $cart->add_fee( __( 'TAX', 'woocommerce')." ($percent%)", $surcharge, false );
}

代码进入您活跃的子主题(或主题)的 function.php 文件或任何插件文件。

经过测试并且可以正常工作……你会得到类似这样的东西:

But for taxes, you should better use default WooCommerce tax feature in Settings > Tax (tab), where con can set the tax rates for each country…
