在本网站的帮助下,我有一个登录脚本,现在有效。问题是我试图限制的页面不是限制访问权限,当我登录到页面时,它仍然可以访问页面。我是PHP的新手,因此您的帮助和评论非常感谢。
页面的代码为
<?php require_once('../Connections/PropSuite.php'); ?>
<?php
error_reporting(E_ALL & ~E_NOTICE);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
function isLoggedIn()
{
if(isset($_SESSION['valid']) && $_SESSION['valid'])
return true;
return false;
}
session_start();
//if the user has not logged in
if(!isLoggedIn())
{
header('Location: http://localhost/PropSuite/index.php');
die();
}
?>
,脚本中的日志代码为
<?php
function validateUser()
{
session_regenerate_id (); //this is a security measure
$_SESSION['valid'] = 1;
$_SESSION['userid'] = $userid;
}
?>
<?php
ob_start(); // Start output buffering
error_reporting(E_ALL & ~E_NOTICE);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
session_start(); //must call session_start before using any $_SESSION variables
$username = isset($_POST['username'])?$_POST['username']:'';
$password = isset($_POST['password'])?$_POST['password']:'';
//connect to the database here
$hostname_PropSuite = "localhost";
$database_PropSuite = "propsuite";
$username_PropSuite = "root";
$password_PropSuite = "root";
$PropSuite = mysql_pconnect($hostname_PropSuite, $username_PropSuite, $password_PropSuite) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database_PropSuite, $PropSuite);
$username = mysql_real_escape_string($username);
$query = "SELECT password, salt FROM admin_users WHERE username = '$username';";
$result = mysql_query($query) or die(mysql_error());
if(mysql_num_rows($result) < 1) //no such user exists
{
header('Location: http://localhost/PropSuite/index.php?login=fail');
die();
}
$userData = mysql_fetch_array($result, MYSQL_ASSOC);
$hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
if($hash != $userData['password']) //incorrect password
{
header('Location: http://localhost/PropSuite/index.php?login=fail');
die();
}
else
{
validateUser(); //sets the session data for this user
}
//redirect to another page or display "login success" message
header('Location: http://localhost/PropSuite/main');
die()
//redirect to another page or display "login success" message
?>
再次感谢您的帮助,并为mods提供帮助,如果我发表类似问题,我深表歉意。
嗯,这是正确的:
if(isset($_SESSION['valid']) && $_SESSION['valid'])
return true;
没有缺少括号?
我会这样写:
if(!empty($_SESSION['valid']) && !empty($_SESSION['valid']) && $_SESSION['valid'] === true) {
return true;
}
也许这是重点。如果这是错误的,那么您的登录时间每次都是正确的。然后,即使没有会话,您也可以看到内容!
希望它有帮助!
返回true,返回false
如果会话显示页面
其他显示请登录以查看此页面或someThign
