Question

我正在向服务器发送一个AJAx请求，以查询与某个类别“目的地”相关的所有“属性”。

条目中的字段名为Destination，其句柄为“destinationCategories”

我的代码目前看起来像这样;

public function actionGetLocation()
{

        $locationId = craft()->request->getParam('id');

       // Find the Actual Category Object from The DB, I did this just in case I need to query based on title, or something else
       // The correct category is being returned

        $criteria = craft()->elements->getCriteria(ElementType::Category);
        $criteria->id = $locationId;
        $criteria->limit = null;
        $selectedCategory = $criteria->first();
        unset($criteria);


        $criteria = craft()->elements->getCriteria(ElementType::Entry);

        // I am now attempting to query for 
        // destinationCategories = the category that I have queried from the DB


        $criteria->destinationCategories = $selectedCategory->id;
        $criteria->limit = null;

        $properties = $criteria->find();


        var_dump($properties);

        foreach($properties as $property)
        {
            echo $property->title;
        }
        exit;
        return $this->returnJson(array('status' => 'ok', 'options' => $subCategories));
}

即使结果可用，查询也会返回null

我在哪里出错我试过

$criteria->destinationCategories = $selectedCategory->id;
$criteria->destinationCategories = $selectedCategory->title;
$criteria->destinationCategories = $selectedCategory->slug;

我想您可能到目前为止已经完成了这个项目：），但是要解决此问题，您可以尝试在使用任何依赖变量之前不要取消设置$ criteria。使用完毕后，请取消设置变量。
