问题描述：

我正在测试我的脚本并且会话值未注册。这是我的错误信息：会话值未被识别

Notice: Undefined index: email1 in /home/content/78/10212078/html/ads/new_topic.php on line 11

Notice: Undefined index: pass1 in /home/content/78/10212078/html/ads/new_topic.php on line 12 ERROR: You do not exist in the system.

这里是线11和12：

$u_email = mysql_real_escape_string($_SESSION['email1']); 
$u_pass = mysql_real_escape_string($_SESSION['pass1']);

这里是new_topic.php的全码：

<?php 
error_reporting(E_ALL); ini_set('display_errors', '1'); 

session_start(); 
include_once "../ads/connect_to_mysql.php"; // Connect to the database 

// Assume they are a member because they have a password session variable set 
// Check the database to be sure that their ID, password, and email session variables all match in the database 
$u_id = mysql_real_escape_string($_SESSION['id']); 
$u_name = mysql_real_escape_string($_SESSION['username']); 
$u_email = mysql_real_escape_string($_SESSION['email1']); 
$u_pass = mysql_real_escape_string($_SESSION['pass1']); 
$sql = mysql_query("SELECT * FROM members1 WHERE id='$u_id' AND username='$u_name' AND email1='$u_email' AND pass1='$u_pass'"); 
$numRows = mysql_num_rows($sql); 
if ($numRows < 1) { 
echo "ERROR: You do not exist in the system."; 
exit(); 
} 

// Check to make sure the URL variables of "sid" and "title" are set 
if (!isset($_POST['ad_id']) || $_POST['ad_id'] == "" || !isset($_POST['ad_title']) || $_POST['ad_title'] == "") { 
echo "Important variables are missing"; 
exit(); 
} else { 
// Acquire the variables and proceed to show them a form for creating a new topic 
$forum_section_id = preg_replace('#[^0-9]#i', '', $_POST['ad_id']); 
$forum_section_title = preg_replace('#[^A-Za-z 0-9]#i', '', $_POST['ad_title']); 
} 
$sql = mysql_query("SELECT * FROM ad_sections WHERE id='$forum_section_id' AND title='$forum_section_title'"); 
$numRows = mysql_num_rows($sql); 
if ($numRows < 1) { 
echo "ERROR: That section deos not exist."; 
exit(); 
}

这里就是会话变量在login.php上设置：

<?php 
// Start Session to enable creating the session variables below when they log in 
session_start(); 
// Force script errors and warnings to show on page in case php.ini file is set to not display them 
error_reporting(E_ALL); 
ini_set('display_errors', '1'); 
// Initialize some vars 
$errorMsg = ''; 
$email = ''; 
$pass = ''; 
$remember = ''; 
if (isset($_POST['email1'])) { 

    $email = $_POST['email1']; 
    $pass = $_POST['pass1']; 
    if (isset($_POST['remember'])) { 
     $remember = $_POST['remember']; 
    } 
    $email = stripslashes($email); 
    $pass = stripslashes($pass); 
    $email = strip_tags($email); 
    $pass = strip_tags($pass); 

    // error handling conditional checks go here 
    if ((!$email) || (!$pass)) { 

     $errorMsg = 'Please fill in both fields'; 

    } else { // Error handling is complete so process the info if no errors 
     include 'connect_to_mysql.php'; // Connect to the database 
     $email = mysql_real_escape_string($email); // After we connect, we secure the string before adding to query 
     //$pass = mysql_real_escape_string($pass); // After we connect, we secure the string before adding to query 
     $pass = md5($pass); // Add MD5 Hash to the password variable they supplied after filtering it 
     // Make the SQL query 
     $sql = mysql_query("SELECT * FROM members1 WHERE email1='$email' AND pass1='$pass' AND email_activated='1'"); 
     $login_check = mysql_num_rows($sql); 
     // If login check number is greater than 0 (meaning they do exist and are activated) 
     if($login_check > 0){ 
       while($row = mysql_fetch_array($sql)){ 

        // Pleae note: Adam removed all of the session_register() functions cuz they were deprecated and 
        // he made the scripts to where they operate universally the same on all modern PHP versions(PHP 4.0 thru 5.3+) 
        // Create session var for their raw id 
        $id = $row["id"]; 
        $_SESSION['id'] = $id;

        $_SESSION['username'] = $username; 
        // Create session var for their email 
        $useremail = $row["email1"]; 
        $_SESSION['useremail'] = $useremail; 
        // Create session var for their password 
        $userpass = $row["pass1"]; 
        $_SESSION['userpass'] = $userpass; 

        mysql_query("UPDATE members1 SET last _log_date=now() WHERE id='$id' LIMIT 1"); 

       } // close while 

       // Remember Me Section 
       if($remember == "yes"){ 
        $encryptedID = base64_encode("g4enm2c0c4y3dn3727553$id"); 
        setcookie("idCookie", $encryptedID, time()+60*60*24*100, "/"); // Cookie set to expire in about 30 days 
        setcookie("passCookie", $pass, time()+60*60*24*100, "/"); // Cookie set to expire in about 30 days 
       } 
       // All good they are logged in, send them to homepage then exit script 
       header("location: index.php?test=$id"); 
       exit(); 

     } else { // Run this code if login_check is equal to 0 meaning they do not exist 
      $errorMsg = "Incorrect login data, please try again"; 
     } 


    } // Close else after error checks 

} //Close if (isset ($_POST['uname'])){

你在哪里设置值各届？ –

从您发布的代码中，无法解释错误。您设置这些会话变量的方式肯定有问题。 –

+0

我放入了变量脚本。 – kwittmack

答

你没有在任何地方设置会话变量。你想上哪儿使用会话功能的所有页面

if (/* username and password are correct */) { 
    $_SESSION['id'] = $row['id']; //taken from db 
    $_SESSION['username'] = $row['username']; 
    // etc 
}
+0

解析错误：语法错误，意外的'）'在第7行 – kwittmack

你用if代替了一些实际代码中的注释吗？我愿意帮忙，但不愿意写你的代码。阅读http://whathaveyoutried.com/ –

答

使用session_start：

设置会话值，你做到以下几点。

后设置会话像这样...

$_SESSION['id'] = $row['id']; 
$_SESSION['username'] = $row['username'];
+0

我改变了变量，它仍然不想识别会话。 – kwittmack
