我正在测试我的脚本，会话值没有注册。这是我的错误消息：
注意：未定义的索引：第11行/home/content/78/10212078/html/ads/new_topic.php中的email1
注意：未定义的索引：第12行/home/content/78/10212078/html/ads/new_topic.php中的pass1 错误：系统中不存在。
这是第11和第12行：
$u_email = mysql_real_escape_string($_SESSION['email1']);
$u_pass = mysql_real_escape_string($_SESSION['pass1']);
以下是new_topic.php的完整代码：
<?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();
}

答案 0 :(得分：0)
您没有在任何地方设置会话变量。
要设置会话值，请执行以下操作：
if ( /* username and password are correct */ ) {
$_SESSION['id'] = $row['id']; //taken from db
$_SESSION['username'] = $row['username'];
// etc
}
答案 1 :(得分：0)
在要使用会话功能的所有网页上使用session_start。
之后设置你的会话......
$_SESSION['id'] = $row['id'];
$_SESSION['username'] = $row['username'];
