Wordpress 239 个字符的意外输出错误

Question

我是 wordpress 新手。这是我的任务。我需要激活一个已经创建的插件。现在，当我尝试激活它时，它给了我以下错误。

插件在激活期间生成了 239 个字符的意外输出。如果您注意到“headers 已发送”消息、联合供稿问题或其他问题，请尝试停用或删除此插件。

所以，我做的第一件事是 google。我发现的原因之一是 white-space 遗留在某处的代码。所以，我遵循它并从我的代码中删除了空白。但没有帮助我。

现在，我将我的代码放在这里 post。谁能帮帮我。真的很烦人。

提前致谢......

Answer 1

不知道为什么？没有人会在这里回答。但是我找到了一个，这是一个愚蠢的错误。

register_activation_hook(文件,'luckydraw_install');

被调用了两次，上面的调用对我没有用。所以我删除了上面的调用，错误消失了。
