WooCommerce基于动态最低订单金额的费用

问题描述：

我需要在购物车中设置最低订单费用，因此如果购物车中的产品总价格不超过10英镑，则需要支付额外费用才能将价格提高到10英镑。WooCommerce基于动态最低订单金额的费用

这里是我目前在购物车阶段运作良好的代码，但是当您到达结账处时，定价部分因某种原因不会停止加载，您无法结帐，任何人都可以帮忙吗？从functions.php的

代码：

你正面临

function woocommerce_custom_surcharge() { 
    global $woocommerce; 
    if (is_admin() && ! defined('DOING_AJAX')) 
     return; 
    $minimumprice = 10; 
    $currentprice = $woocommerce->cart->cart_contents_total; 
    $additionalfee = $minimumprice - $currentprice; 
    if ($additionalfee >= 0) { 
     wc_print_notice(
      sprintf('We have a minimum %s per order. As your current order is only %s, an additional fee will be applied at checkout.' , 
       wc_price($minimumprice), 
       wc_price($currentprice) 
      ), 'error' 
     ); 
     $woocommerce->cart->add_fee('Minimum Order Adjustment', $additionalfee, true, ''); 
    } 
} 
add_action('woocommerce_cart_calculate_fees','woocommerce_custom_surcharge');

答

无限加载旋转的问题是由于wc_print_notice()，当它在woocommerce_cart_calculate_fees胡克的使用。这看起来像一个错误。

如果使用wc_add_notice()，问题不存在但通知显示2次。

此外，我已经重新审视你的code.The 唯一的解决办法是它在2个独立的功能划分：

// NOTICE ONLY IN CART PAGE 
add_action('woocommerce_cart_calculate_fees', 'add_custom_surcharge', 10, 1); 
function add_custom_surcharge($cart_object) { 

    if (is_admin() && ! defined('DOING_AJAX')) 
     return; 

    $minimumprice = 100; 
    $currentprice = $cart_object->cart_contents_total; 
    $additionalfee = $minimumprice - $currentprice; 

    if ($additionalfee >= 0) { 
     $cart_object->add_fee('Minimum Order Adjustment', $additionalfee, true); 

     if(! is_checkout()){ 
      $message = sprintf(__('We have a minimum %s per order. As your current order is only %s, an additional fee will be applied.', 'woocommerce'), wc_price($minimumprice), wc_price($currentprice)); 
      wc_print_notice($message, 'error'); 
     } 
    } 
} 

// NOTICE ONLY IN CHECKOUT PAGE 
add_action('woocommerce_before_checkout_form', 'custom_surcharge_message', 10, 0); 
function custom_surcharge_message() { 
    $cart_object = WC()->cart; 
    $minimumprice = 100; 
    $currentprice = $cart_object->cart_contents_total; 
    $additionalfee = $minimumprice - $currentprice; 
    if ($additionalfee >= 0) { 
     $message = sprintf(
      __('We have a minimum %s per order. As your current order is only %s, an additional fee will be applied.', 'woocommerce'), 
      wc_price($minimumprice), wc_price($currentprice) 
     ); 
     wc_print_notice($message, 'error'); 
    } 
}

代码放在您的活动子主题（或主题）的function.php文件或者也在任何插件文件中。

经过测试，完美适用于WooCommerce 3+
