session_start()
session_register("varl");
$_SESSION['varl']="xxx";然后再测试一下看能不能用
不知道你怎么用的?session1.php
<?php
session_start();
$var1 = "test";
$_SESSION['var1']=$var1;
echo $_SESSION['var1'];
?>
<a href="session2.php">session2</a>session2.php
<?
session_start();
echo $_SESSION['var1'];
?>楼主再试,直接点连接,看是不是可以打印出test来?
<?PHP
$Account=$_POST['username'];
$PW=$_POST['password'];
if(empty($_SESSION['User']))
{if (($Account!="") && ($PW!=""))
{
$conn=mssql_connect("127.0.0.1","sa","1" ) or die("Could not connect: " );
mssql_Select_db("njc2",$conn);
$strSQL="SELECT * from yhzc where username= '$Account' and password='$PW' ";
$result = mssql_query($strSQL,$conn);
$row = mssql_num_rows($result);
if ($row)
{
session_start();
session_register("User");
session_register['UserPW'];
$_SESSION['User']=$Account;
$_SESSION['UserPW']=$PW;
header("Location:cx.php");
echo "输入正确";
}
else
{
echo "<center>没有该用户或密码错误!</center><br>";
echo "<center><a href=login.php>"."[返回]"."</a></center>";
}
}
}
else
echo $_SESSION['User'];
?>cx.php
<?
session_start();
if($_SESSION['User']=="")
header("Location: login.php");
?>
这样子还是没用,大家帮我看看
然后跳回login.php可以进入
但是一开始就用index.php(left.php/login.php)就打不开,不知道怎么办啊
