你好，我在测试站点中遇到了一个记住我的功能时遇到的问题。目前，我正在尝试将nement_me存储在一个将从现在开始1个月过期的cookie中。这个想法是，如果用户按下"记住我"按钮，他应该在关闭浏览器并破坏会话后将登录时，如果他不按复选框，则应在关闭浏览器时登录(会话被销毁时，都应将其登录。(。目前它有效，但是只有当用户按下Navbar中的登录按钮时(他跳过表单并重定向到profil(。我想要的是用户在不需要按登录的情况下打开索引页面时，可以看到与用户打开索引页面时登录的用户相对应的。connect.php文件：

Navbar代码未检查是否设置了Cookie。这就是为什么即使您通过cookie登录，页面也不是您的。
添加到Navbar代码以下代码。在require_once 'connect.php';
if( isset($_COOKIE['remember_me']) AND trim($_COOKIE['remember_me'] ) != "" ) {
$_SESSION['user'] = $_COOKIE['remember_me'];
}
也在Navbar代码中，将空的$ _session ['user']视为未记录：
替换：
<?php if (!isset($_SESSION['user'])): ?>
with：
<?php if (!isset($_SESSION['user']) OR trim( $_SESSION['user'] ) == ""): ?>
新代码：
<?php
require_once 'connect.php';
if( isset($_COOKIE['remember_me']) AND trim($_COOKIE['remember_me'] ) != "" ) {
$_SESSION['user'] = $_COOKIE['remember_me'];
}
?>
