请教大佬一个php的问题【已解决】

我想打开网站，未登录的用户跳转到注册/登录页，注册/登录后才可以跳转到首页。

我在index.php顶部加了一段：

<?php
//未登录，跳转至欢迎界面
if (!isset($_SESSION['user'])) {
header('location:login.php');
exit(); //防止继续执行
}
?>

复制代码

然后在注册登录页顶部加了一段：

<?php
session_start(); //首先要开始 session
//已登录，跳转至主页
if (isset($_SESSION['user'])) {
header('location:index.php');
exit();
}
?>

复制代码

效果是，打开网站能跳转到注册/登录页，但是输入账号密码后，就提示，该网页无**常运作，将您重定向的次数过多。

请问大佬，这是啥原因啊？

这一行
loginCookie($helloConfig['ppsecure'],$userInfo['uid'],$userInfo['nickname'],$userInfo['groupid']);

上下都可以添加 $_SESSION['user'] = $userInfo['uid'];
然后index.php 头部也加session_start();

  这个看起来人家是有用cookie判断登录了，$loginInfo['uid']>0 就是判断是否登录成功的
  index.php 肯定没有$_SESSION['user'] 的所以会跳回登录但是人家原来的代码有判断已经登录了
  最后的办法就是不用用你家的session判断  直接 index.php
开头
<?php
require(dirname(__FILE__)."/global.php");
if ( !$loginInfo['uid'] > 0 )
                     {
                           //跳去登录
                     }

因为你登陆完没设置$_SESSION['user']

login.php里面登陆成功里面加一行$_SESSION['user']=$你的用户名变量

.host. · 发表于 2019-11-4 17:21:16

index.php页面参照 login.php 页面
添加一个 session_start();

注意位置

还是不行。。。就像2楼大佬说的，那个加一行一行$_SESSION['user']=$你的用户名变量，不知道在哪加。。

登录成功后的那个header跳转之前设置$_SESSION['user']=你的用户名
但是如果你没设置的话不可能跳来跳去的只会重新跳回login.php让你再登录。只有你设置了，才有可能一直跳来跳去重定向太多，如果设置了，那需要在index.php的第二行加上 session_start();

你把login.php的完整代码贴上来吧
