在 Kohana 之外访问 Kohana 中设置的会话变量

Question

我正在尝试将KCFinder 与CKEditor 和Kohana 一起使用。我需要每个用户都可以访问他们自己的上传文件夹。为此，我想将当前用户 ID 传递给 KCFinder。为了安全地做到这一点，我不能通过 URL 作为 GET 变量传递它，所以我需要通过会话来做到这一点。

我尝试在 Kohana 中设置变量，当我在 Kohana 中 var_dump($_SESSION) 时，变量就在那里。当我在 KCFinder 中这样做时，它不存在。我检查了session_id 并注意到它在页面之间发生变化，因此我使用URL 作为GET 变量将session_id 传递给KCFinder，然后在KCFinder 中设置session_id 使其匹配。但是，当我var_dump($_SESSION) 时，该变量仍然不可用。

这是我的 Kohana 操作：

public function action_edit()
{
    $this->template->javascripts[] = '/ckeditor/ckeditor.js';
    $_SESSION['KCFINDER']['user_id'] = Auth::instance()->get('id');
    var_dump(session_id(), $_SESSION['KCFINDER']);

    $id = (int)$this->request->param('id');
    $this->layout = Request::factory('document/update/'.$id)->execute()->body();
    $this->template->js_custom .= "var phpsessionid = '".session_id()."';";
}

// document/update action
public function action_update()
{
    $id = (int)$this->request->param('id');
    if ( ! $id)
    {
        throw new HTTP_Exception_400('No document ID was specified. Please go back and try again.');
    }
    $document = ORM::factory('Document', $id);
    if ( ! $document->loaded())
    {
        throw new HTTP_Exception_400('No valid document ID was specified.');
    }
    $layout = View::factory('layouts/documents/edit')
        ->bind('back_link', $back_link)
        ->bind('values', $values)
        ->bind('errors', $errors)
        ->bind('success', $success)
        ->bind('is_acp', $is_acp);

    $is_acp = (strpos(Request::initial()->uri(), 'acp') !== FALSE);

    if ( ! $is_acp AND Auth::instance()->get('id') != $document->user_id)
    {
        throw new HTTP_Exception_403('Unauthorised access. You do not have permission to edit this document.');
    }
    elseif ($document->is_published AND ! Auth::instance()->get('is_admin'))
    {
        throw new HTTP_Exception_403('Unauthorised access. You cannot edit a published document.');
    }

    $back_link = $is_acp ? '/acp/documents' : '/account';

    $values = array();
    $errors = array();
    foreach ($document->table_columns() as $key => $null)
    {
        $values[$key] = $document->$key;
    }
    if (Request::initial()->method() == Request::POST)
    {
        // We assume that is_published and is_paid are unchecked. Later on we check to see if they are checked and change the values.
        if ($document->is_published == 1 AND $is_acp)
        {
            $values['is_published'] = -1;
        }
        if ($document->is_paid == 1 AND $is_acp)
        {
            $values['is_paid'] = 0;
        }
        foreach (Request::initial()->post() as $key => $val)
        {
            if ($key == 'is_published')
            {
                // Check for a first time publish, and if it is run the publish method to save the PDF.
                if ($document->is_published == 0)
                {
                    Request::factory('document/publish/'.$document->id)->query(array('no_redirect' => TRUE))->execute();
                }
                $values[$key] = 1;
            }
            elseif ($key == 'is_paid')
            {
                $values[$key] = 1;
            }
            else
            {
                $values[$key] = $val;
            }
        }
        $document->values(Request::initial()->post(), array('title', 'summary', 'category_id', 'content'));
        if ($is_acp)
        {
            $document->is_published = $values['is_published'];
            if ($document->is_published == 1)
            {
                $document->date_published = time();
            }
            $document->is_paid = $values['is_paid'];
        }
        try
        {
            $document->save();
            $success = TRUE;
        }
        catch (ORM_Validation_Exception $e)
        {
            $errors = $e->errors('models');
        }
        catch (Exception $e)
        {
            throw new HTTP_Exception_500($e->getMessage);
        }
    }
    $this->response->body($layout->render());
}

这是我的 KCFinder 配置的顶部：

$session_id = @$_GET['phpsession'];
session_start();
session_id($session_id);
define('ROOT', str_replace('eshop/kcfinder', '', __DIR__), TRUE);
var_dump(session_id(), $_SESSION); exit;

当我打开 KCFinder 时，会话是空的（或者只有 KCFinder 默认会话）并且与 Kohana 会话无关。谁能帮我解决这个问题？

您的问题是函数调用的顺序。在设置作为参数传递的会话 id 之前，您正在启动会话（如果没有传递 id，它将生成一个具有新 id 的新会话）——它需要反过来。

http://php.net/manual/en/function.session-id.php:

如果指定id，它将替换当前会话ID。为此，session_id() 需要在 session_start() 之前调用。
