两个文件：login.php和adduser.php
在login.php中session有值，跳转到adduser.php后session空，怎么回事？谢谢！！！！！！
login.php
<?php
session_start();
require "func.php";
$username=$_POST['username'];
$pwd=$_POST['pwd'];
$str = "select * from admin where username = '$username' and password = '$pwd'";
$result = check($str);
$result = mysql_fetch_object($result);
$userid=$result->id;
$uname =$result->username;
$levels = $result->levels;
//echo $userid;
if($result){
session_id(SID);
$_SESSION["username"]=$uname;
$_SESSION["userid"]=$userid;
$_SESSION["levels"]=$levels;
//print_r($_SESSION);
//echo $_SESSION["levels"];
header("location:main.php");
}
else{
header("location:index.php");
}
?>

adduser.php

<?php
session_start();
$levels = $_SESSION["levels"];

var_dump($_SESSION);
if($levels!="超级管理员"){
echo "<script language=javascript>alert('权限不足');</script>";
echo "<script language=javascript>window.history.back(-1);</script>";

}
?>
