我有一个登录脚本和一个functions.php脚本来检查是否设置了会话用户名和cookie。当用户登录时，如果他们选择记住我，则应该设置cookie。但问题是，脚本有效，但cookie没有设置，因此用户没有登录。我在这里搜索了很多主题并尝试了尽可能多的解决方案，但是我仍然得到相同的结果或最终给我更多的错误。
if (isset($_POST['rem']) && $_POST['rem'] == 'on') > { setcookie('MCLatestUser', $token, 31622400, > '/'); session_regenerate_id(true); }如果记得被选中，这是应该设置cookie的代码部分。

functions.php（这是检查会话和cookie变量的脚本部分）：
function loggedIn() {
if (isset($_SESSION['username']) && !empty($_SESSION['username']) && isset($_COOKIE['MCLatestUser'])) {
return true;
} else {
return false;
}
}
脚本有效，但没有发送cookie。我在这里的智慧结束了，现在已经工作了超过4-5个小时，打开了超过35个镀铬标签只是为了解决这个问题。我可能会忽略一个小细节。 Login Page Link
如果我从函数脚本
中删除&& $_COOKIE['MCLatestUser']，它就有效
答案 0 :(得分：0)
setcookie('MCLatestUser', $token, 31622400, '/');
这个方法在第三个参数中有一些问题。它应该基于当前时间。

我明白了。事实证明这是浏览器的错。我在Microsoft Edge和Mozilla Firefox上尝试过它并且有效。所以我查看了这个问题，而我所要做的只是clear my cookies and site data在chrome上。感谢那些帮助过的人和那些想要但不能/没有的人。
