Question

我正在使用3.1.13 SilverStripe CMS和Framework。在我的Page.php（类页面）中创建一个函数并在我的视图（page.ss）中初始化它后，我遇到了麻烦。我想为我的项目创建一个分页。以下是源和跟踪的错误：

[User Error] Uncaught Exception: The request must be readable as an array.
GET /?flushtoken=88455a3cc5497ee38dd7a61d75370221&flush=all

Line 28 in /var/www/project-name/framework/core/PaginatedList.php


Source

19   * Constructs a new paginated list instance around a list.
20   *
21   * @param SS_List $list The list to paginate. The getRange method will
22   *        be used to get the subset of objects to show.
23   * @param array|ArrayAccess Either a map of request parameters or
24   *        request object that the pagination offset is read from.
25   */
26  public function __construct(SS_List $list, $request = array()) {
27      if (!is_array($request) && !$request instanceof ArrayAccess) {
28          throw new Exception('The request must be readable as an array.');
29      }
30 
31      $this->request = $request;
32      parent::__construct($list);
33  }

问题出在哪里？我正在关注this指令，当我在视图中调用我的函数时它会失败。

没关系！我刚刚意识到如果我想让$this->request工作，我需要将该函数放入class Page控制器。
