我在login.php的有用
session_start();//启动会话
Session_register("userID");//创建会话变量
创建session对象。
我的session.php代码是
<?
session_start();
//检查userID是否被注册为session
if(!isset($_SESSION['userID']))
{
echo "<script>";
echo "alert(\"Please Sign in before\");";
echo "location.href=\"javascript: window.open(\'index.php\',\'_parent\')\";";
echo "</script>";
}
?>现在我是set2.php，将session.php作为外挂来控制用户有没有登入。可是在login.php显示到我已登入成功，但是跳转到set.php就弹出对话框说我没登入！

?>set2.php代码只有
<?
include("session.php");
?>其他的都是html代码
$_SESSION['userID']不行吗？
这个session问题在本地测试时并没有出现，在我把网站传上空间后就出现这个问题的
是上传到国外空间的
