如何验证表单字段到数据库
这个问题在这里已经有了答案：
我认为它应该工作
$usernamename = $_GET['usernamename'];
$code = $_GET['code'];
$email = $_GET['email'];
$res = mysql_query("SELECT * FROM `table` WHERE `usernamename` = '$usernamename' AND `code` = '$code' AND `email` = '$email' LIMIT 1 ") or die(mysql_error());
if($row = mysql_fetch_assoc($res))
{
header("location:index.php");
exit;
}
