我有一个 html 页面，它使用 php 文件查询数据库，然后让用户登录，否则拒绝访问。我遇到的问题是它只是重定向到 php 文件的 url，并且从不对发生的事情提供反馈。这是我第一次使用 html、php 和 mysql 作业，所以请原谅我缺乏技术术语/知识。

HTML 文件

 Login Form 



Username:  


Password:  

PHP文件

define('DB_HOST', 'localhost');
define('DB_NAME', 'project2');
define('DB_USER','root');
define('DB_PASSWORD','');

$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error());
/*
$ID = $_POST['user'];
$Password = $_POST['pass'];
*/
function SignIn()
{
session_start(); //starting the session for user profile page
if(!empty($_POST['user'])) //checking the 'user' name which is from Sign-In.html, is it empty or have some text
{
    $query = mysql_query("SELECT * FROM customers where userName = '$_POST[user]' AND pass = '$_POST[pass]'") or die(mysql_error());
    $row = mysql_fetch_array($query) or die(mysql_error());
    if(!empty($row['userName']) AND !empty($row['pass']))
    {
        $_SESSION['userName'] = $row['pass'];
        echo "SUCCESSFULLY LOGIN TO USER PROFILE PAGE...";

    }
    khác
    {
        echo "SORRY... YOU ENTERD WRONG ID AND PASSWORD... PLEASE RETRY...";
    }
}
}
if(isset($_POST['submit']))
{
    SignIn();
}

?>

Hãy thử cách này:

if (!empty($row['userName']) AND !empty($row['pass'])) {

    $_SESSION['userName'] = $row['pass'];
    header("Location: mypage.php?is_login=1");
    exit; // exit is must or you can use retun also
}

else {

    header("Location: mypage.php?is_login=0");
    exit; // exit is must or you can use retun also             
}

?>

在页面mypage.php

if (isset($_GET['is_login']) ) {

    if ('1' == $_GET['is_login']) {

        echo "sucess";    
    }

    else {

        echo "failure";        
    }    
}
?>
