在 prestashop 1.7 中使用 feature_id 和 id_feature_value 获取产品功能

Question

我想使用 prestashop 1.7 的核心文件自定义运输方式 在 php 上，我有一个数组 features。在产品数组中，功能只有 id。 id_feature 和 id_feature_value。但我需要获取特征名称和值的实际值。

$products = Context::getContext()->cart->getProducts();
        foreach ($products as $key => $product) 
        {  
            foreach($product['features'] as $feature){
                $featuresvalue = FeatureValue::getFeatureValuesWithLang($this->context->language->id, $feature['id_feature']);
                echo "<pre>";
                print_r($featuresvalue['id_feature_value']);
                echo "/<pre>";
            }
       }

这是完整的产品数组

但我没有得到这些值。有人知道如何获取值吗？提前致谢

尝试像这样在特征数组中添加特征的值

       $productsCart = Context::getContext()->cart->getProducts();
     
        foreach ($productsCart as $product) {
        foreach ($product['features'] as &$feature) {    
                $featureValueObj = new FeatureValue($feature['id_feature_value'],Context::getContext()->language->id);
                $feature['value']= $featureValueObj->value;

            echo "<pre>";
            print_r($product['features']);
            echo "</pre>";
           }
         }
