Question

我知道有很多这样的问题，但是我找不到与我的案子相关的细节。要么，要么他们没有答案。

我编写了一个非常简单的PHP脚本，并上传到了zip文件夹中的wordPress网站，当我尝试激活该插件时，WordPress给了我一条消息：“插件无法激活，因为它触发了致命错误”。它实际上并没有给我任何错误消息。我已经将WP_DEBUG，WP_DEBUG_LOG和WP_DEBUG_DISPLAY都设置为true，但是根据假定的错误，这些都没有更新。看来我无法找出致命错误到底是什么。

我对如何解决此问题感到困惑。任何帮助都会有用。

    exit();
  }
  else{

    exit();
  }

?>

此插件的一般想法是，它将挂接到wordPress网站上由javascript生成的A标签，CURL发布到另一个网站进行登录，然后重定向到该网站，希望绕过用户身份验证，因为由于使用了CURL，该用户已经登录。

Answer 1

此代码对我有用。但是有一个问题，为什么要添加exit（）;在else条件内，它破坏了插件的激活过程。

请检查并告知我。
