php登录页面 session

Question

我已经创建了一个运行良好的注册页面，信息被插入到 mysql 中，但是当我想登录时，由于某种原因它没有引导我到 account.php。它说“重定向到:account.php 有人可以帮我处理代码吗？我已经把什么放在了 login.php 和 account.php

谢谢

登录.php

$submitted_username = ''; 
if(!empty($_POST))

    $query = " 
        SELECT

     $query_params = array( 
        ':username' => $_POST['username'] 
    ); 

    try 
    { 

        $stmt = $db->prepare($query); 
        $result = $stmt->execute($query_params); 
    } 
    catch(PDOException $ex) 
    { 

        die("Failed to run query: " . $ex->getMessage()); 
    } 

  not. 
     switch it to true. 
    $login_ok = false; 



    $row = $stmt->fetch(); 
    if($row) 
    { 

        $check_password = hash('sha256', $_POST['password'] . $row['salt']); 
        for($round = 0; $round < 65536; $round++) 
        { 
            $check_password = hash('sha256', $check_password . $row['salt']); 
        } 

        if($check_password === $row['password']) 
        { 

            $login_ok = true; 
        } 
    }

先知道什么是die()

您可能希望使用 JavaScript 重定向来执行此操作，因为您希望显示一条消息。

在 3 秒或任何你想要的 set_timeout() 中使用重定向脚本在你的页面上放置一个 JS。
