Question

这里的任何帮助将不胜感激。我是数据库世界的新手。好的我已经为新用户注册创建了我的表单，在此人输入所有详细信息后假设他们是正确的，他们将收到一条消息，表示欢迎访问该网站，并且信息将被放入数据库。

然而我收到了这个：警告：mysql_num_rows（）要求参数1为资源，布尔值在第31行的C：\ xampp \ htdocs \ office \ index.php中给出

并且用户条目也不会进入数据库。请帮忙:(

index.php在下面但我也有我的连接文件如下（连接到SQL文件和索引是不同的文件）：

<?php
mysql_connect("127.0.0.1","root","") or die(mysql_error());
mysql_select_db("office");
?>
