我有一个网站在一个不太知名的 CMS 上运行，叫做 Ushahidi。内置 OpenID 功能，人们可以使用 Facebook 或 Google 登录。

我没有足够的开发技能来理解这里发生的事情，但是，我似乎几乎可以让它工作，除了，我在我自己的谷歌登录上尝试测试它时收到以下错误：

检测到错误导致无法加载此页面。如果此问题仍然存在，请联系网站管理员。应用程序/控制器/login.php [503]：未定义变量：用户

我怀疑，但不确定，定义变量很容易，但由于我缺乏知识，我希望在这里问某人是否可以看到我需要在哪里定义变量。第 503 行是大约 100 行的更大代码块的一部分，我知道在此处发布更大的代码块不是一个好习惯，但我真的不确定什么是相关的和不相关的。所以请原谅我。我用粗体突出显示了第 503 行所在的位置。谁能指出我必须在这里做什么？

问题是代码在实际定义之前使用了几行 $user 。不过，这可能是一个错字——也许第 503 行的 $openid_user->user->dashboard() 可能会起作用，尽管它是一个 WAG。
