问题

在 "catalog/controller/product.php" 中，我使用以下代码存储了一些数据：

$this->document->setSomeData("data");

我需要在 "system/library/response.php" 中使用以下代码来读取数据：

$this->document->getSomeData

但是在那里无法访问 document 类。我该怎么办？

英文:

I stored some data in "catalog/controller/product.php" OC v2.0.3.1 by using

> $this->document->setSomeData("data");

I need to read the data in "system/library/response.php" by using

> $this->document->getSomeData

But the document class is not reachable there. what can i do?

你可以将 $registry 传递给系统/framework.php 中的响应类，如下所示：

$response = new Response($registry);

在响应类中添加：

private $registry;
public function __construct($registry){
    $this->registry = $registry;
}

使用：

$document = $this->registry->get('document');
$document->setSomeData("data");

英文:

You can pass $registry into response class in your system/framework.php like this:

$response = new Response($registry);

In your response class add:

private $registry;
public function __construct($registry){
    $this-&gt;registry = $registry;
}

use:

$document = $this-&gt;registry-&gt;get(&#39;document&#39;);
$document-&gt;setSomeData(&quot;data&quot;);
