【问题描述】：
我希望有人可以帮助解决从直觉上看应该很简单的问题，但我无法找到答案。出于某种原因，当我的用户注销时，他必须单击两次注销才能使其正常工作。我读过这个：
Any idea why I have to click the logout button twice to logout?
但它似乎不起作用。这是我的注销按钮代码。有什么想法吗？谢谢！

【问题讨论】：
-
请提供更多代码 - 否则我们只能猜测出了什么问题。
-
我已向此页面提供了完整代码 -
-
我会首先在每个 if 语句中的文件中包含一些日志记录（如果您没有好的调试器）。将 cookie/其他变量的相关值写入文件并指定它们来自哪个条件。 $_POST['logout_btn'] 例如每次用户 clikcs 注销时都会执行吗？
