Question

我想在我自己的班级中更改自定义功能（产品功能）（Artikeleigenschaften）的值。

更改产品价值非常简单：

$productObj = new Product($produktId);
$productObj->setFieldsToUpdate(array('ean13'));
$productObj->ean13 = "johndoo";
$productObj->save();

但有没有类似的方法来更改产品功能？

Answer 1

这是我的解决方案：要更新产品功能，您必须更新数据库中的2个表： ps_feature_value 和 ps_feature_value_lang

这样做：

$id_feature_value = (int)FeatureValue::addFeatureValueImport
( 
  (int)$feature['id_feature'],
  $newFeatureValue,
  (int)$produktId,
  $this->context->language->id,
  1 // $custom
);
Product::addFeatureProductImport(
    $produktId, (int)$feature['id_feature'], $id_feature_value
);

使用NOT自定义值更新功能使用：

$arr = FeatureValue::getFeatureValueLang($id_dropdown);
foreach ( $arr AS $item)
    if ($item['id_lang'] == $this->context->language->id)
    {
        $feature_val_name = $item['value'] ;
    }

$id_feature_value = (int)FeatureValue::addFeatureValueImport
( 
   (int)$feature['id_feature'],
   $feature_val_name,
   $product->id,
   $this->context->language->id, 
   false 
);
$product->addFeatureProductImport( $product->id , (int)$feature['id_feature'], $id_feature_value );

是的，我从未尝试过这样做，但你可以试试这个：

Product::addFeatureProductImport($productObjc->id, $id_feature, $id_feature_value);

Answer 3

我基于ImportControlloer创建了此功能。将此功能添加到Product.php覆盖并使用

 /**
 * Adds a feature value to a Product. If You want to have feature selected from dropdown leave $custom to false.
 * @param int|$id_product
 * @param int|$id_feature_group
 * @param string|$feature_value
 * @param bool|true $custom
 * @param int|$id_lang
 * @return bool
 */
public static function setFeatureValueToProduct($id_product, $id_feature_group, $feature_value, $custom = false, $id_lang)
{
    $group_feature_obj = Feature::getFeature($id_lang, $id_feature_group);

    if ($group_feature_obj){
        $feature_name = $group_feature_obj['name'];
        $feature_value = $feature_value ? trim($feature_value) : '';
        $position = false;

        if (!empty($feature_name) && !empty($feature_value)) {
            $id_feature = (int)FeatureCore::addFeatureImport($feature_name, $position);

            $id_feature_value = (int)FeatureValue::addFeatureValueImport($id_feature, $feature_value, $id_product, $id_lang, $custom);
            if (Product::addFeatureProductImport($id_product, $id_feature, $id_feature_value)){
                Feature::cleanPositions();
                return true;
            } else {
                return;
            }
        }
    } else {
        return;
    }
}

使用示例：

Product::setFeatureValue(1597, 15,  'Dracarys', false, 1);

它将下拉列表值“ Dracarys”上载到ID为1597的产品中，并将组特征上载为ID 15的产品。如果要使其为自定义值（未预定义），只需将第4个参数设置为true。

Answer 4

Product::addFeatureProductImport($productObjc->id, $id_feature, $id_feature_value);

这会将功能及其值分配给产品。但是我们需要特征和值的ID。以下代码对我有用。

  $feature = new Feature();
            $feature->name = [
                $lang_id => "string"
            ];
            $feature->position = Feature::getHigherPosition() + 1;
            $feature->add();
            $featurevalue = new FeatureValue;
            $featurevalue->id_feature = $feature->id;
            $featurevalue->value = [
                $lang_id => "string"
           ];
            $featurevalue->add();
$product->addFeatureProductImport($product->id, $feature->id, $featurevalue->id);
