Question

我正在尝试php中的登录页面示例。我收到错误消息：此网页有重定向循环 详细说：错误代码：ERR_TOO_MANY_REDIRECTS

这是我的代码：

的index.php

<?php
include('login.php'); // Includes Login Script

if(isset($_SESSION['login_user'])){
header("location: profile.php");
}
?>


                <form action="" method="post">
                <label>UserName :</label>
                <input id="name" name="username" placeholder="username" type="text">
                <label>Password :</label>
                <input id="password" name="password" placeholder="**********" type="password">
                <input name="submit" type="submit" value=" Login ">
                <span><?php echo $error; ?></span>
            </form>

的login.php

<?php
session_start(); 
$error=''; 

if (isset($_POST['submit'])) {
    if (empty($_POST['username']) || empty($_POST['password'])) {
        $error = "Username or Password is invalid";
    }
    else
    {

        $username=$_POST['username'];
        $password=$_POST['password'];

        $connection = mysql_connect("localhost", "root", "");

        $username = stripslashes($username);
        $password = stripslashes($password);
        $username = mysql_real_escape_string($username);
        $password = mysql_real_escape_string($password);

        $db = mysql_select_db("rjtest", $connection);

        $query = mysql_query("select * from login where myPassword='$password' AND myUserName='$username'", $connection);
        $rows = mysql_num_rows($query);
        if ($rows == 1) {
            $_SESSION['login_user']=$username;
            header("location: profile.php"); 
        } else {
            $error = "Username or Password is invalid";
        }
    }
}
?>

profile.php

<?php
include('session.php');
?>
<!DOCTYPE html>
<html>
<head>
<title>Your Home Page</title>
<link href="style.css" rel="stylesheet" type="text/css">
</head>
<body>
<div id="profile">
<b id="welcome">Welcome : <i><?php echo $login_session; ?></i></b>
<b id="logout"><a href="logout.php">Log Out</a></b>
</div>
</body>
</html>

session.php文件

<?php

$connection = mysql_connect("localhost", "root", "");

$db = mysql_select_db("rjtest", $connection);
session_start();

$user_check=$_SESSION['login_user'];

$ses_sql=mysql_query("select myUsername from login where myUsername='$user_check'", $connection);
$row = mysql_fetch_assoc($ses_sql);
$login_session =$row['username'];
if(!isset($login_session)){

header('Location: index.php'); 
}
?>

logout.php

<?php
session_start();
if(session_destroy())
{
header("Location: index.php");
}
?>

我似乎无法弄明白为什么。我得到此代码的网站现在处于非活动状态，所以这就是我在这里问这个问题的原因。希望你们能帮助我。很抱歉这篇文章很长。

评论回答：

我认为你的代码是错误的，而你却没有看到它，导致它与它应该向你展示的错误作斗争。

您$login_session =$row['username'];使用＆＃34;用户名＆＃34;作为行，但您未在查询select myUsername from login where myUsername中选择它。

所以，我认为如果那一行实际上并不存在，那么你需要做

$login_session =$row['myUsername'];

这个网页有一个重定向循环 - PHP登录
