我正在创建一个简单的网页 PHP 和 MySQL 联合登录系统。我遇到了一个问题，简而言之，我无法登录。如果您可以快速查看我的代码，那就太好了！我更像是一名 HTML/CSS 开发人员。谢谢！

好的，这是我的登录页面（login.php），

<?php
session_start();
require_once 'Membership.php';
$membership = new Membership();

// If the user clicks the "Log Out" link on the index page.
if(isset($_GET['status']) && $_GET['status'] == 'loggedout') {
    $membership->log_User_Out();
}

// Did the user enter a password/username and click submit?
if($_POST && !empty($_POST['username']) && !empty($_POST['pwd'])) {
    $response = $membership->validate_User($_POST['username'], $_POST['pwd']);
}


?>

</form>


</div>
</div>
</body>
</html>

这是其他几个 PHP 文档，（它们要短得多）..

该文件名为“Membership.php”

<?php

require 'Mysql.php';

class Membership {

    function validate_user($un, $pwd) {
        $mysql = New Mysql();
        $ensure_credentials = $mysql->verify_Username_and_Pass($un, md5($pwd));

        if($ensure_credentials) {
            $_SESSION['status'] = 'authorized';
            header("location: index.php");
        } else return "Please enter a correct username and password";

    } 

    function log_User_Out() {
        if(isset($_SESSION['status'])) {
            unset($_SESSION['status']);

            if(isset($_COOKIE[session_name()])) 
                setcookie(session_name(), '', time() - 1000);
                session_destroy();
        }
    }

    function confirm_Member() {
        session_start();
        if($_SESSION['status'] !='authorized') header("location: success.php");
    }

}

和.. 一个名为“MySQL.php”的文件

<?php

// Define constants here

define('DB_SERVER', 'localhost');
define('DB_USER', 'noahtech_dbuser');
define('DB_PASSWORD', 'dbuseraccess');
define('DB_NAME', 'noahtech_secure');

和一个名为“Constants.php”的重复 PHP 文档

<?php

// Define constants here

define('DB_SERVER', 'localhost');
define('DB_USER', 'noahtech_dbuser');
define('DB_PASSWORD', 'dbuseraccess');
define('DB_NAME', 'noahtech_secure');

请帮忙！我是否正确格式化了“定义”数据库服务器、用户、密码和名称？

标签没有属性input name。input只是name

input name="username"
input name="pwd"

应该

name="username"
name="pwd"

编辑1：

您还应该检查用户是否按下submit按钮。所以

if($_POST && !empty($_POST['username']) && !empty($_POST['pwd'])) {
    $response = $membership->validate_User($_POST['username'], $_POST['pwd']);
}

应该

if (isset($_POST['sumbit'])){
if($_POST && !empty($_POST['username']) && !empty($_POST['pwd'])) {
    $response = $membership->validate_User($_POST['username'], $_POST['pwd']);
}
}
