练习PHP登录代码无限循环

标签: php mysql loops login

我只是从一本书,HeadFirst PHP和MySQL学习PHP和MySQL的基础知识,并且在其中一个教程中遇到了障碍。它是放入预设用户名和密码并访问页面的基本表单。但是,无论我是否输入正确或错误,它只会让我回到登录表单。在谷歌浏览器上它是一个完整的循环,在Safari上,它说尽管输入了正确的信息但我输错了信息。我还没有找到任何答案。

authorize.php代码位于

之下
    <?php
  // User name and password for authentication
  $username = 'rock';
  $password = 'roll';

  if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) ||
    ($_SERVER['PHP_AUTH_USER'] != $username) || ($_SERVER['PHP_AUTH_PW'] != $password)) {
    // The user name/password are incorrect so send the authentication headers
    header('HTTP/1.1 401 Unauthorized');
    header('WWW-Authenticate: Basic realm="Guitar Wars"');
    exit('<h2>Guitar Wars</h2>Sorry, you must enter a valid user name and password to access this page.');
  }
?>

引用它的admin.php页面如下:

<?php
  require_once('authorize.php');
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <title>Guitar Wars - High Scores Administration</title>
  <link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
  <h2>Guitar Wars - High Scores Administration</h2>
  <p>Below is a list of all Guitar Wars high scores. Use this page to remove scores as needed.</p>
<?php
    require_once('appvars.php');
    require_once('connectvars.php');

// Connect to the database
    $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

// Retrieve the score data
    $query = "SELECT * FROM guitarwars ORDER BY score DESC, date ASC";
    $data = mysqli_query($dbc, $query);

// Loop through the array of more data, formatting it as HTML
    echo '<table>';
    while ($row = mysqli_fetch_array($data)) {

        // Display the score data
        echo '<tr class="scorerow"><td><strong>' . $row['name'] . '</strong></td>';
        echo '<td>' . $row['date'] . '</td>';
        echo '<td>' . $row['score'] . '</td>';
        echo '<td><a href="removescore.php?id=' . $row['id'] . '&amp;date=' . $row['date'] . 
        '&amp;name=' . $row['name'] . '&amp;score=' . $row['score'] . '&amp;screenshot=' . $row['screenshot'] . 
        '">Remove</a></td></tr>';
    }

    echo '</table>';

    mysqli_close($dbc);

?>

</body>
</html>

我还在Fatcow网络服务器上托管这个,因为我只是一名学生,如果这有任何区别的话。

如果您发现错误,或者我只是使用过时的方法进行此类登录验证,请告诉我。这本书已有几年历史了,所以您可能会了解更多最新的学习资料。

编辑:我执行此操作的具体网址是maxwellantonucci.com/php_practice3/admin.php,适用于想直接查看的人

编辑2:更新以显示引用authorize.php的整个admin.php页面
