为什么unexpectedReserveError.html会被触发？如代码所示，这是否意味着会话令牌不匹配？我在PHP上非常糟糕......
修改
添加问题说明。正如此代码所代表的那样，它可以正常工作，即有一个htm格式（第二个代码集），并将其变量传输到后端页面（第一个代码集）。让我感到困惑的是，错误页面随机发生。并且很多人抱怨错误页面弹出，从而放弃了页面。
我只能触发错误页面一次，而且只能触发一次，即便如此，也没有明显的线索，为什么会发生这种情况。因此我最重要的问题是..因为如果你查看代码，你可以看到有一个会话令牌匹配，如果它不起作用，它会触发unexpectedReserveError.html页面？ （有两个错误页面，header('location: URL/reserveError.html');＆amp; header('location: URL/unexpectedReserveError.html');
最重要的是，我试图弄清楚在什么情况下，unexpectedReserveError页面会被触发，因为它会导致问题。
