用PHP创建登录系统

Bli*_*meo 4 php passwords login username

有人可以帮帮我吗？我的用户名是Blimeo,我的密码是"密码",但是当我输入我的凭据时,它说"拒绝访问"就像我告诉它的那样.我100%确定我正确配置了mySQL数据库.

<html>
<body>
<?php
echo sha1('Blimeo');
if (isset($_REQUEST['attempt'])) {

    $link = mysql_connect('localhost', 'root', 'password') or die('Could not connect to database');
    $user = mysql_real_escape_string($_POST['user']);
    $password = sha1(mysql_real_escape_string($_POST['password']));
    mysql_select_db('test_users');
    $query = mysql_query(
        "SELECT user 
        FROM users 
        WHERE user = '$user' 
        AND password = '$password'
        ") or die(mysql_error());
    mysql_fetch_array($query);
    $total = mysql_num_rows($query);
    if ($total > 0) {
        session_start();
        $_SESSION['user'] = 'blah';
        header('location: dashboard.php');
    }
    else {
        echo '<br>Access denied!';

    }
}


?>
<form method="post" action="login.php?attempt">
    Enter your username:<input type="text" name="user"/><br/>
    Enter your password:<input type="password" name="password"/><br/>
    <input type="submit"/>
</form>
</body>
</html>
