Question

我不知道我的代码有什么问题，当没有成员页面时，登录会将我重定向到成员页面地址，404错误不是问题，当我登录时它会将我重定向到登录页面当我在会员页面中写下这段代码时。

 <?php 
session_start();
if(!isset($_SESSION['user_level'])or ($_SESSION['user_level'] != 0)){
    header('location: login.php');
exit();
}?>
<!DOCTYPE html>
<html>
<head>
    <title>
        Admin page
    </title>
    <style>
        table{text-align: center;}
    </style>
</head>
<body>
<?php 
if($_SESSION['fname']){
    echo 'welcome to admin page '. $_SESSION['fname'] . "<br>";
}
?>
<input type="button" value="Log Out" onclick="window.location=' logoutt.php '">
</body>
</html>

登录页面代码

<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
    $dbcon=mysqli_connect('localhost','mahmud91','password','postaldb')or die('Couldn\'t connect to database'.mysqli_error($dbcon));
    if(!empty(trim($_POST['email']))){
        $email=mysqli_real_escape_string($dbcon,trim($_POST['email']));
    }else{
        $email=false;
    }
    if(!empty(trim($_POST['psword']))){
        $psword=mysqli_real_escape_string($dbcon,trim($_POST['psword']));
    }else{
        $psword=false;
    }if($email && $psword){
        $query="SELECT fname,user_id,user_level FROM users WHERE (email='$email' AND psword=SHA1('$psword'))";
        $result=mysqli_query($dbcon,$query);
        if(@mysqli_num_rows($result)==1){
            $_SESSION=mysqli_fetch_array($result,MYSQLI_ASSOC);
            $_SESSION['user_level']=(int)$_SESSION['user_level'];
            $url=($_SESSION['user_level']===1) ? "adminnpage.php" : "memberrpage.php";
            header('location: '.$url);
        }else{
            echo "Sorry no match was found to email or password";
        }
    }else{
        echo" Please try again";
    }
}

您忘记在php标记

后面的登录页面顶部开始会话

session_start();

当我按下登录时，我的代码有什么问题会将我重定向到登录页面？
