我正在尝试存储当前 URL 以用于登录重定向脚本。我在用：
$_SESSION['url'] = $_SERVER['REQUEST_URI'];
在每个页面顶部的脚本中，我想要密码保护，如下所示：
<?php
//prevents caching
header("Expires: Sat, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
header("Cache-Control: post-check=0, pre-check=0",false);
session_cache_limiter();
session_start();
$_SESSION['url'] = $_SERVER['REQUEST_URI'];
require('config.php');
require('functions.php');
//this is group name or username of the group or person that you wish to allow access to
// - please be advise that the Administrators Groups has access to all pages.
if (allow_access(Administrators) != "yes")
{
include ('no_access.html');
exit;
}
?>
no_access.html 看起来像这样：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>NO ACCESS ALLOWED</title>
</head>
<body>
<b><font size="6">Access Denied!!!</font></b><p>Please login with proper
credentials:</p>

<P><font face="Verdana"><font color="#2852A8">

me from this computer</font></font></p>
<P><font color="#2852A8">
<INPUT TYPE="submit" NAME="submit" VALUE="Login" style="font-family: Verdana"></font></P>
</FORM>
<p> </p>
</body>
</html>
redirect.php 看起来像这样：
<?
//prevents caching
header("Expires: Sat, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");

session_cache_limiter();
session_start();
die(print($_SESSION['url']));
if(isset($_SESSION['url']))
$url = $_SESSION['url']; // holds url for last page visited.
else
$url = "/bob.php"; // default page for
//require the functions file
require ("config.php");
require ("functions.php");
//check to see if cookies are already set, remember me
if ((!$lr_user) || (!$lr_pass))
{
$username = $_POST[username];
$password = $_POST[password];
}else{
$username = $lr_user;
$password = $lr_pass;
}
//if username or password is blank, send to errorlogin.html
if ((!$username) || (!$password))
{
header("Location:$base_dir/errorlogin.html");
exit;
}
//sets cookies to remember this computer if the user asks to
if ($_POST[remember] == "Yes")
{
setcookie("lr_user", $username, $duration, "/", $domain);
setcookie("lr_pass", $password, $duration, "/", $domain);
}
if ($_POST[activate] == "Yes")
{
//make the connection to the database
$connection = @mysql_connect($server, $dbusername, $dbpassword) or die(mysql_error());
$db = @mysql_select_db($db_name,$connection)or die(mysql_error());
//build and issue the query
$sql ="UPDATE $table_name SET verified = '1' WHERE username = '$_POST[username]'";
$result = @mysql_query($sql,$connection) or die(mysql_error());
}
//sets session variables
sess_vars($base_dir, $server, $dbusername, $dbpassword, $db_name, $table_name, $username, $password);
//check to see if the user has to change their password
if ($_SESSION[pchange] == "1")
{
$_SESSION[redirect] = "$base_dir/pass_change.html";
}
//check to see if the user has activated the account
if ($_SESSION[verified] == "0")
{
$_SESSION[redirect] = "$base_dir/not_activated.html";
}
//make the connection to the database
$connection = @mysql_connect($server, $dbusername, $dbpassword) or die(mysql_error());
$db = @mysql_select_db($db_name,$connection)or die(mysql_error());
//build and issue the query
$sql ="SELECT * FROM banned";
$result = @mysql_query($sql,$connection) or die(mysql_error());
while ($sql = mysql_fetch_object($result))
{
$banned = $sql -> no_access;
if ($username == $banned || $REMOTE_ADDR == $banned)
{
include ('banned.html');
exit;
}
}
$last_log = last_login();
//updates table with last log as now
$sql = "UPDATE $table_name SET last_login = '$last_log' WHERE username = '$_SESSION[user_name]'";
$result = @mysql_query($sql,$connection) or die(mysql_error());
if (($_SESSION[redirect] != "$base_dir/errorlogin.html") && ($log_login == "1"))
{
include('loglogin.php');
}
//redirects the user
header("Location:$url");
?>
<head><title>Redirect</title></head>
由于某种原因$_SESSION['url']没有传递给redirect.php。die(print($_SESSION['url']));什么都不返回。
有人可以帮助解决这个问题吗？
谢谢，
