我一直在努力保护我服务器上的一些页面。我能够创建一个登录屏幕和所有内容，并且运行良好。之后，我决定通过添加一些 CSS（背景、水平居中对齐等）来美化它。在那之后，出于某种原因，即使我输入了登录信息，之前也没有任何处理，登录后我将能够看到页面的其余部分。

我实现登录的方式是，我创建了一个名为 的页面login.php，并且我也有index.php一个我试图访问的页面。在index.php，我require以前总是login.php先访问。我还必须theme.css让事情看起来更好。

我不明白的是，它以前是怎么工作的，但现在突然停止工作了。登录页面正常工作后，除了 CSS 文件之外，我什至没有触摸任何东西。

这是我的代码：

索引.php

<?php
    require('login.php');
?>

<?php
    require('session.php');
?>

<html>
    <head>
        <title>Protected Page</title>
        <link rel="stylesheet" href="css/theme.css" type="text/css">
    </head>
    <body>
        <form enctype="multipart/form-data" action="add.php" method="POST">
            Name: <input type="text" name="name"><br>
            E-mail: <input type="text" name = "email"><br>
            Phone: <input type="text" name = "phone"><br>
            Photo: <input type="file" name="photo"><br>
            <input type="submit" value="Add">
        </form>
        <table>
            <tr>
                <td><form method="post"><input type="submit" name="submit" value="Check Status"></form></td>
                <td><form action="logout.php" method="post"><input type="submit" name="submit" value="Logout"></form></td>
            </tr>
        </table>
    </body>
</html>

登录.php

<?php
    ## put sha1() encrypted password here - example is 'hello'
    $password1 = '43b1c8633e86765546bb1f44c4d654ed223fa064';
    ## username dictionary
    $uname1 = 'ismail';

    session_start();

    if (!isset($_SESSION['logged']))
    {
        $_SESSION['logged'] = false;
    }

    if (isset($_POST['password']))
    {
        if ((sha1($_POST['password']) == $password1) && ($_POST['username'] == $uname1))
        {
            $_SESSION['logged'] = true;
            $user = $_POST['username'];
            $pwd = $_POST['password'];
        }
        else
        {
            die ('Incorrect password');
            session_destroy();
        }
    }

    if (!$_SESSION['logged']):
?>

在 login.php 中，您的</form>标签位于错误的位置。

login.php 表单应编码如下：-

    <br />
    <form method="post">      <!-- moved! -->
    <table class="center">
        <tr>
            <td>Username:</td>
            <td><input type="text" name="username"></td>
        </tr>
        <tr>
            <td>Password:</td>
            <td><input type="password" name="password"></td>
        </tr>
    </table>
    <input type="submit" name="submit" value="Login">
    </form>                 <!-- moved! -->

您的代码和页面中有很多错误。我解决了所有问题，并通过集成代码制作了您想要的页面。

根据下面给出的代码更改页面（不要更改您的 css 及其名称。您的“CSS”工作正常。）：
