将代码重写为

$conn=mysql_connect("localhost","csuwebdev","") or die ('Error: ' . mysql_error());
mysql_select_db("csuwebdev",$conn);

在对您的表格进行查询之前,您需要将数据库连接传递给mysql_select_db


mysql_*)扩展程序自PHP 5.5.0起已弃用,将来会被删除。相反,应使用MySQLiPDO_MySQL扩展名。切换到PreparedStatements甚至可以更好地抵御SQL注入攻击!

以上代码的PDO版本。 [虽然没有测试]

$dbh =  new PDO('mysql:host=localhost;dbname=csuwebdev', 'username', 'password');
$stmt = $dbh->prepare("INSERT INTO draft (name, sitename,pages,colors,navigation) VALUES(?,?,?,?,?)");
$stmt->execute(array($name,$sitename,$pages,$color,$navigation));
