为了解决它的努力，你提交你需要if语句包裹登录代码的形式，这将决定是否提交表单之前登录的问题。

if($_SERVER['REQUEST_METHOD'] == 'POST') 
{ 
    // now do the login code 
}

它不是重定向的第二个问题可能是由于您的回音的重定向之前，其发生。在重定向之前，您无法回显或打印任何内容。因此，删除所有这些回声$计数和回声$电子邮件等。

也检查您的错误日志或打开错误报告的进一步细节。最后，如果您认为它不起作用，请使用mysql_error（）来调试查询。

打开错误报告（在脚本的最顶部）：

error_reporting(E_ALL); 
ini_set('display_errors', '1');

你有另外一个问题是这样的代码：

$sql2=mysql_query("SELECT * FROM registration WHERE email='$email' and password='$pass'"); 
$result=mysql_query($sql2);

将其更改为

$sql2 ="SELECT * FROM registration WHERE email='$email' and password='$pass'"; 
$result=mysql_query($sql2); 

if(!$result) 
{ 
    die('error: ' . mysql_error()); // remove this after you have finished debugging 
}

我试过所有这些但仍然相同problemm ..它不给我任何错误 – Paso 2012-03-22 08:17:21

添加后检查并删除回显后显示新代码。 – MrCode 2012-03-22 08:30:43

ive推他的代码，但在差异任务plz看到它overthere..and非常感谢你 – Paso 2012-03-22 08:43:13

如果头已经发送，则不能使用header("location:member.php");。发送标题是因为您的header函数之前有html字符，而且不仅header,session_register也有同样的问题。

尝试：

<?php 

session_start(); 
include('configdb.php'); 
mysql_select_db("upload_site2", $con); 

// username and password sent from form 
$email=$_POST['email']; 
$pass=$_POST['pass']; 

// To protect MySQL injection (more detail about MySQL injection) 
$email = stripslashes($email); 
$pass = stripslashes($pass); 
$email = mysql_real_escape_string($email); 
$pass = mysql_real_escape_string($pass); 

$sql2=mysql_query("SELECT * FROM registration WHERE email='$email' and password='$pass'"); 
$result=mysql_query($sql2); 
echo $email; 
// Mysql_num_row is counting table row 
$count=mysql_num_rows($result); 
// If result matched $myusername and $mypassword, table row must be 1 row 

if($count==1){ 
// Register $myusername, $mypassword and redirect to file "login_success.php" 
session_register("email"); 
session_register("password"); 
header("location:member.php"); 
} 
else{if(!empty($email))$answer='wrong';}

还是它不是重定向到第二页:: S：小号 – Paso 2012-03-22 08:06:10

添加'的error_reporting（E_ALL）''之前在session_start（）;'和检查，也许你有一些其他错误。 – Narek 2012-03-22 08:11:06

什么也没有发生 – Paso 2012-03-22 08:16:55

重定向页面后添加exit();。

它没有工作：S – Paso 2012-03-22 09:02:02

它是否进入里面如果（$ count == 1）条件？ – heyanshukla 2012-03-22 09:06:46

<?php 
    session_start(); 
    if (!isset($_SESSION['email'])) { 
header('Location: index.php'); 

} 
echo $_SESSION['email']; 

?> 
<html> 

<head> 
<title>Secured Page</title>

<body> 

<p>This is secured page with session: <b><?php echo $_SESSION['email']; ?></b> 
<br>You can put your restricted information here.</p> 
<p><a href="logout.php">Logout</a></p> 


<form action="upload.php" method="post" enctype="multipart/form-data">
