register.php:

.....
if($user->addUser($username,$nickname ,$birthday,$gender ,$gameid,$city ,$jointime,$bloodtype ,$avoirdupois,$bodilyform ,$oicq,$icq,$msn,$userintro ,$toevery,$gameroll,$constellation,$email,$province,$love,$address,$zip))

echo "<script>alert('注册成功');window.history.back();</script>";
}
}
else
echo "<script>alert('注册失败,该用户名或者email已经注册！');window.history.back();</script>";

问题：在调用$image->uploadFiles($photo,$photo1,$email))时，$photo,$photo1的值并没有传到函数中，请各位指教！

把php.ini文件里面

register_globals = Off成On就行了
