【问题描述】：

如果购物车中的所有产品具有指定的运费等级，我希望取消所有这些运费，我已设法实施该规则如果购物车中的任何产品具有指定的运输等级，则删除费率 - 我已经尝试过，如下所示。

这里是工作的 php：

//ROYAL MAIL ONLY FOR SPECIFIC PRODUCTS

add_filter( 'woocommerce_package_rates',     'hide_table_shipping_for_shipping_class', 10, 2 );

$in_cart = false;
foreach( WC()->cart->cart_contents as $key => $values ) {

if( $values[ 'data' ]->get_shipping_class_id() === $shipping_class_target ) {
  $in_cart = true;
  break;
 }

}

我尝试使用以下方法创建异常：

foreach( WC()->cart->cart_contents as $key => $values ) {
    if( $values[ 'data' ]->get_shipping_class_id() == 0 ) { 
$in_cart = false;
break;
}
elseif( $values[ 'data' ]->get_shipping_class_id() === $shipping_class_target ) {
  $in_cart = true;
  break;
 } 
}
if( $in_cart ) {... etc

这不起作用:(

最终使用 LoicTheAztec 的编辑（谢谢）：

add_filter( 'woocommerce_package_rates',              'hide_table_shipping_for_shipping_class', 10, 2 );
function hide_table_shipping_for_shipping_class( $rates, $package ) {

$targeted_class = 137; // <== Your targetted shipping class

// Loop through cart items to find out if any hasn't the targetted shipping class
foreach( WC()->cart->cart_contents as $key => $values ) {
    // IF One item is found without this shipping class
    if( $values[ 'data' ]->get_shipping_class_id() != $targeted_class ) {

##----- This is what I've added, I couldn't make it work in your nice clean format----##
unset( $rates['mh_wc_table_rate_plus_108' ] );
unset( $rates['mh_wc_table_rate_plus_107' ] );
unset( $rates['mh_wc_table_rate_plus_106' ] );
unset( $rates['mh_wc_table_rate_plus_105' ] );
unset( $rates['mh_wc_table_rate_plus_104' ] );

        return $rates; // <== FOUND! We exit returning all Shipping rates
    } 
}

## --------------------- REMOVING SHIPPING METHOD RATES IDS ---------------------- ##

$instance_ids = array(

// Loop: Unsetting each shipping method rate Ids
foreach( $instance_ids as $instance_id )
    unset( $rates["mh_wc_table_rate_plus_$instance_id"] );

return $rates;

更新 （更正了一些错误）

您应该尝试以下方法，我会在其中寻找没有运输等级的物品。我还重新访问并压缩了您的代码：

add_filter( 'woocommerce_package_rates',     'hide_table_shipping_for_shipping_class', 10, 2 );
function hide_table_shipping_for_shipping_class( $rates, $package ) {

    $targeted_class = 137; // <== Your targetted shipping class

    // Loop through cart items to find out if any hasn't the targetted shipping class
    foreach( WC()->cart->cart_contents as $key => $values ) {
        // IF One item is found without this shipping class
        if( $values[ 'data' ]->get_shipping_class_id() != $targeted_class ) {
            return $rates; // <== FOUND! We exit returning all Shipping rates
        } 
    }

    ## --------------------- REMOVING SHIPPING METHOD RATES IDS ---------------------- ##
    ##                 (when all cart items have the targeted shipping class)

    // All shipping instance IDs to be removed
    $instance_ids = array(
        '1', '2', '3', '4', '5', '6', '7', '8', '9', '10',
        '11', '12', '13', '14', '15', '16', '17', '18', '19', '20',
        '21', '22', '23', '24', '25', '26', '27', '28', '29', '30',
        '31', '32', '33', '34', '35', '36', '37', '38', '39', '40',
        '41', '42', '43', '44', '45', '46', '47', '48', '49', '50',
        '51', '52', '53', '54', '55', '56', '57', '58', '59', '60',
        '61', '62', '63', '64', '65', '66', '67', '68', '69', '70',
        '71', '72', '73', '74', '75', '76', '77', '78', '79', '80',
        '81', '82', '83', '84', '85', '86', '87', '88', '89', '90',
        '91', '92', '93', '94', '95', '96', '97', '98', '99', '100',
        '101', '102', '103',
    );

    // Loop: Unsetting each shipping method rate Ids
    foreach( $instance_ids as $id )
        unset( $rates['mh_wc_table_rate_plus_'.$id] );

    return $rates;
}

代码进入活动子主题（或活动主题）的function.php文件中。

经过测试，它应该适合你。

有时，您可能需要刷新运输方式：
1) 先清空购物车。
2) 前往配送区域设置，然后禁用/保存并重新启用/保存相关配送方式。

答案基于：Hide shipping method for specific shipping classes in woocommerce

非常感谢！（特别是为了整理那些乱七八糟的东西！！）但是我很挣扎，因为这似乎撤销了最初的（微小的）成功——当购物车中唯一的物品属于目标运输类别时，它不再删除表格费率？
太棒了！谢谢你:)
是的，完美 - 我已经添加了一些东西（如果这看起来像肉店，我很抱歉！！）在其他运费为时删除目标运费等级的运费可用（我不知道在这里说的最佳方式）我将其添加到我的问题中，因为这里没有足够的空间
