为什么我用session 保存提交没起作用的啊?
下面是代码,各位看看有什么问题吗?

<?//session.php
session_start();
if($submit)
{
$def_user="admin";
$def_pwd="admin";
if($user==$def_user)
{
if($pwd=$def_pwd)
{
$manage=$user;
session_register('manage');
echo "成功登陆";
echo "<meta http-equiv='refresh' content='0;URL=index.php'>"; }
else
{
echo "<meta http-equiv='refresh' content='2;URL=login.php'>";
}
}
else
{
echo "<meta http-equiv='refresh' content='2;URL=login.php'>";
}
}
?>

各位好人帮帮手,我想了很久了,都没有找出问题,好蠢啊.希望大家帮下手.

用$_SESSION["manage"]＝$manage保存
用$_SESSION["manage"]读取

session_register不提倡用了

if($pwd=$def_pwd)
??????????????????????????????????????????????????
你要是这样写的话，永远也不会起作用

[clubsondy]

<?
session_start();
if($_SESSION['submit'])
{
$def_user="admin";
$def_pwd="admin";
if($user==$def_user)
{
if($pwd==$def_pwd)
{
$manage=$user;
$_SESSION['manage']=$manage;
echo "成功登陆";
echo "<meta http-equiv='refresh' content='0;URL=index.php'>";
exit();}
else
{
echo "<meta http-equiv='refresh' content='2;URL=login.php'>";
}
}
else
{
echo "<meta http-equiv='refresh' content='2;URL=login.php'>";
}
}
?>
改成这样还不行啊.好郁闷啊......................

检查register_globals的状态

怎样检查,我是新手,请大家帮下手.

$_SESSION['submit'] 中是什么，print出来看看。
