登錄時總是重定向到Index.php

好日子給大家，我在這裏有一個小問題。這裏是我的代碼登錄時總是重定向到Index.php

的index.php

<?php 
include('login.php'); // Includes Login Script 
?>

session.php文件

// SQL Query To Fetch Complete Information Of User 
$ses_sql=mysql_query("select username from ciislogin where username='$user_check'", $connection); 
$row = mysql_fetch_assoc($ses_sql); 
$login_session =$row['username']; 
if(!isset($login_session)){ 
mysql_close($connection); // Closing Connection 
header('Location: index.php'); // Redirecting To Home Page 
} 
?>

說明 1.My的index.php是我登錄（輸入用戶名和密碼） 2.login.p hp和session.php是我的與數據庫通信的php命令。

我的問題是，當我嘗試運行這個，它工作完美，但即時通訊使用本地wammp，但是當我上傳這個在我的webhosting，並把正確的用戶名和密碼它總是重定向到index.php，而不是我想要的網頁。

有幫助嗎？

你必須把你的的session_start（）在第一行,,,爲總檢查出來

的login.php：

<?php 
session_start(); // Starting Session 
ini_set('display_errors', 1); 
error_reporting(~0); 
$error=''; // Variable To Store Error Message 
if (isset($_POST['submit'])) { 
if (empty($_POST['username']) || empty($_POST['password'])) { 
$error = "Username or Password is invalid"; 
} 
else 
{ 
// Define $username and $password 
$username=$_POST['username']; 
$password=$_POST['password']; 
// Establishing Connection with Server by passing server_name, user_id and password as a parameter 
$connection = mysql_connect("localhost", "root", ""); 
// To protect MySQL injection for Security purpose 
$username = stripslashes($username); 
$password = stripslashes($password); 
$username = mysql_real_escape_string($username); 
$password = mysql_real_escape_string($password); 
// Selecting Database 
$db = mysql_select_db("ciis", $connection); 
// SQL query to fetch information of registerd users and finds user match. 
$query = mysql_query("select username,password from ciislogin where password='$password' AND username='$username'", $connection); 
$rows = mysql_num_rows($query); 
if ($rows == 1) { 
$_SESSION['login_user']=$username; // Initializing Session 

      switch ($username) 
      { 
      case "ciisdistrict5": 
      header("location: district5/Home.php"); 
      break; 

      case "ciisbagbag":

      break; 

      case "ciispasongputik": 
      header("location:brgy_PasongPutik/Home.php");  
      break; 

      case "ciissanagustin": 
      header("location:brgy_SanAgustin/Home.php");  
      break; 

      case "ciisstalucia":

      break; 

      case "ciisstamonica": 
      header("location:brgy_StaMonica/Home.php");  
      break; 
      } 

} else{ 
    $error = true; 
    echo ("Sorry Wrong Username or Password"); //if either field is empty 
    } 
mysql_close($connection); // Closing Connection 
} 
} 
?>

session.php文件：

<?php 
session_start();// Starting Session 
// Establishing Connection with Server by passing server_name, user_id and password as a parameter 
$connection = mysql_connect("localhost", "root", ""); 
// Selecting Database

$user_check=$_SESSION['login_user']; 
// SQL Query To Fetch Complete Information Of User 
$ses_sql=mysql_query("select username from ciislogin where username='$user_check'", $connection); 
$row = mysql_fetch_assoc($ses_sql); 
$login_session =$row['username']; 
if(!isset($login_session)){ 
mysql_close($connection); // Closing Connection 
header('Location: index.php'); // Redirecting To Home Page

我該如何解決這個問題先生？我會在哪裏放正確的代碼？ – 2015-02-11 18:44:47

@ PaulEdwardPagente99編輯 – 2015-02-11 18:48:58

先生我嘗試你的代碼，但它不工作似乎當我的用戶名和密碼是正確的代碼去index.php – 2015-02-11 18:56:34
