【问题描述】：
我正在开发一个 PHP 项目。我有一个奇怪的错误。我的 PHP 项目在本地服务器（WAMP 服务器）上运行良好。但是在将其托管在实时服务器上之后，它就无法正常工作了。
问题：在Login.php 页面上创建的会话变量未在Report.php 页面上传递值。代码如下：
Login.php
<?php
$con=mysql_connect("mysql51****************","username","password")or die(mysql_error());
$select_db=mysql_select_db("database_name",$con);
$error="";
if(isset($_POST['submit']))
{
$userid=mysql_real_escape_string($_POST['username']);
$password=mysql_real_escape_string($_POST['password']);
$sql="SELECT * FROM user_details WHERE user_name='{$userid}' AND password='{$password}' ";
$result = mysql_query($sql);
if(mysql_num_rows($result) <= 0)
{
$error="Invalid UserId or Password.";
}
else
{
//session_set_cookie_params(60*60*60, '/', '.abcxyz.com');
ini_set('session.cookie_domain','.abcxyz.com');
session_start();
//$userid=mysql_real_escape_string($_POST['abc']);
//echo($userid);
$_SESSION['user']=$userid;
$_SESSION['userid']="true";
//echo $_SESSION['userid'];
$error="Successfully Login";
//header("Location: admin.php?page=report");
/*echo '<script type="text/javascript">alert("header is not working.' . $_SESSION['user'] . '");</script>';
*/ ?>
<script type="text/javascript">
/*alert("Please select a Source And Destination Country"); */
window.location.href='admin.php?page=report';
</script>
<?php
}
}
?>

编辑：
正如答案所建议的，我编辑如下：
Login.php：
<?php
session_start();
$con=mysql_connect("mysql51*************","username","password")or die(mysql_error());...
...
Report.php：
<?php
session_start();
include("connections/Connections.php");...
...
但我仍然没有在Report.php 中获得会话变量值。
【问题讨论】：
-
你没有在
Report.php中调用session_start() -
报错？你还需要说明你使用 windows/linux 的主机吗？
