仅允许对 WooCommerce 中特定运输区域之外的特定产品进行本地提货

Question

我的商店里有多种产品，但其中一种产品（易燃）只能通过特定的运输公司运输；不幸的是，该公司无法覆盖全国。因此，如果客户购买了易燃产品，并且该产品不在唯一可以运送该产品的公司的覆盖范围内，那么除了本地取货之外，他不应该看到任何其他运送选项。

到目前为止，我有这段代码（由不同的 StackOverFlow 答案提供）：

function filter_woocommerce_package_rates( $rates, $package ) {

    // Shipping zone

    //echo 'entrando';

    $shipping_zone = wc_get_shipping_zone( $package );

    $product_ids = array( 2267 ); // HERE set the product IDs in the array

    $method_id = 'weight_based_shipping:38'; // HERE set the shipping method ID that I want to hide

    $found = false;

    

    // Get zone ID

    $zone_id = $shipping_zone->get_id();

    

    //echo $shipping_zone;

    //echo $zone_id;

    

    // NOT equal

    if ( $zone_id != 8 ) {

        // Unset a single rate/method for a specific product

        foreach( $package['contents'] as $cart_item ) {

        if ( in_array( $cart_item['product_id'], $product_ids ) ){

            $found = true;

            break;

        }

        }

         if ( $found )

            unset( $rates[$method_id] );

    }

    return $rates;

}

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

但我不知道为什么不起作用。甚至“回声”也不起作用。
