此代码重定向到登录页面，而不是停留在同一主页。

Question

我希望通过会话或 cookie 访问我的网站。但是在编写这段代码之后，页面需要两个条件都为真而不是一个。这里有什么问题？

<?php
    if(((isset($_SESSION['SUCCESS']) && $_SESSION['SUCCESS'] != "") || 
    (isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != "")) 
     == false){
        $_SESSION['ERROR'] = "Please login first";
        header('location: login.php'); 
    }

?>

Answer 1

不用写== false。尝试删除它

if((isset($_SESSION['SUCCESS']) && $_SESSION['SUCCESS'] != "") || 
(isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != "")
 ){
    $_SESSION['ERROR'] = "Please login first";
    header('location: login.php'); 
}

Answer 2

if(isset($_COOKIE['is_logged_in']) && $_COOKIE['is_logged_in'] != ""){
    if(!isset($_SESSION['SUCCESS'])){
        $_SESSION['SUCCESS'] = true;//or whatever you want
    }
}

然后检查会话

if(!isset($_SESSION['SUCCESS']) || $_SESSION['SUCCESS'] == ""){
    $_SESSION['ERROR'] = "Please login first";
    header('location: login.php');
}else{
    //move to home page
}

此代码重定向到登录页面，而不是停留在同一主页。

This code redirects to login page instead of staying in same home page.
