Question

可能重复：
Getting MYSQL ERROR from my site

我已经托管了一个bux网站CrimsonBux.Com。脚本一切都很棒。密码恢复页http://crimsonbux.com/login.php?option=forgot只有一个问题。在页面上输入电子邮件地址和CAPTCHA后，用户将被重定向到此页面http://crimsonbux.com/recover.php。在recover.php页面中，用户面临错误。错误列在下面。

Warning: mysql_query() [function.mysql-query]: Access denied for user 'crimst1d'@'localhost' (using password: NO) in /home/crimst1d/public_html/recover.php on line 19

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/crimst1d/public_html/recover.php on line 19

这里我的网站无法连接到MySQL数据库。怎么连接？

这是我对recover.php页面的配置。

Answer 1

您需要将用户添加到您的数据库以及脚本可以通过mysql_connect和mysql_select_db连接到的数据库。

放在脚本的顶部：

mysql_connect('localhost', 'username', 'password');
mysql_select_db('database name');

Answer 2

以下是解决安全漏洞的方法。改变这个：

$emailx = mysql_query("SELECT COUNT(*) AS cnt FROM tb_users WHERE email='{$_POST['email']}'");

到此：

$emailUntainted = mysql_real_escape_string($_POST['email']);
$emailx = mysql_query("
    SELECT COUNT(*) AS cnt
    FROM tb_users
    WHERE email='{$emailUntainted}'
");

你有两个要修复;做一些阅读，理解为什么这是必要的:)。

发布脚本：正如@Esailija所说，最好使用PDO和预备语句，但这需要您学习更多知识。快速获取此修复程序，然后在可以的时候切换到PDO。
