我在wamp服务器的www目录中拥有我的网站的所有文件，我正在运行Windows 7。 www目录是我们大多数人都知道的本地主机，我在该目录中有我的table.sql文件以及我网站的php文件。
我的问题是我在phpmyadmin上加载了table.sql并测试了sql文件，并且当我去注册时工作时说“这个用户名已经被占用！”虽然数据库中没有任何内容...怪异对？
我已经尝试了好几天让它正常工作我已经从我的网站上发布了一些代码，看看这里是否有人可以指出错误，以便我可以纠正它。
注意：网站自行运行正常，尝试注册和登录时遇到问题。
最后一个问题我是否必须在connect.php文件或myphpadmin上使用mysql的usr和密码？
这是主页面的源代码或标记。 “demo.php”

以下是connect.php文件的代码

$conn = mysql_connect($host,$username,$password) or die('Unable to establish a DB connection');
mysql_select_db($db_database,$conn);
mysql_query("SET names UTF8");

这里是table.sql文件的代码
--
-- Table structure for table `tz_members`

UNIQUE KEY `usr` (`usr`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
我正在我的机器上运行最新版本的wamp。

您的数据库连接不正确。所以每次都是条件
if(mysql_affected_rows($link)==1)
变为虚假，它会显示您可以看到的消息。
$db_host = 'localhost';
$db_user = 'admin';
$db_pass = 'Shadowman80';
$db_database = '<databaseName>'; //Here it might cause issue
答案 1 :(得分：1)
我可以看到你使用sql文件作为你的数据库写在这一行：
$ db_host ='localhost'; $ db_user ='admin'; $ db_pass ='Shadowman80'; $ db_database ='table.sql';
尝试使用$ db_database作为实时数据库连接，例如使用mysql_select_db（“db_name”）作为连接的意思

是的，我想出来谢谢，虽然我很感谢你的回答，你们给了我很多想法，我做了重新安装和重新配置phpmyadmin和mysql中提琴它工作有证书错误谢谢：D
