Php Magento 2根据添加到购物车的商品属性定制结账布局

我有一个自定义模块，可以向magento 2签出添加自定义属性。但我无法指定在签出步骤中显示自定义属性的条件。我正在努力使它只显示在结帐的基础上，产品属性“是”设置为“是”。 下面是模块LayoutProcessorPlugin.php文件

            $options = [
                ['value' => '0', 'label' => 'No'],

        }

        return $options;
    }
}

现在，我可以通过下面的方法从布局中删除自定义订单属性名称“test”

unset($jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
                    ['shippingAddress']['children']['shipping-address-fieldset']['children']['test']);

但我想基于产品属性“test”指定为“yes”的任何一个项来实现上述方法

我尝试了下面的代码

   $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 

    // get cart items
    $items = $cart->getItems();
     $isyes="0";
    // get product attribute value of cart items
    foreach ($items as $item){
if(!$item->getData('test')=="yes"){
$isyes="1";
}
};
if($isyes=="1"){
unset($jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children']
                    ['shippingAddress']['children']['shipping-address-fieldset']['children']['test']);
}

---

但我无法基于此条件从签出布局中删除自定义属性。请帮忙。谢谢

有什么更新吗？有什么更新吗？
