即使密码正确,我的登录系统也会将您重定向到索引页面,以下是一些可能存在问题的文件:
登录检查.php:
<?php
require("header.inc.php");
if (isset($_POST['submitButton']))
{
if(!isset($_POST['username']))
{
die("The username and password fields were not set.");
}
else if(!isset($_POST['password']))
{
die("Error: The password field was not set.");
}
$password = hash("sha512", $_POST['password']);
$query = mysql_query("SELECT `id` FROM `users` WHERE `name` = '" . mysql_real_escape_string($_POST['username']) . "' AND `password` = '" . mysql_real_escape_string($password) . "'");
if(mysql_num_rows($query))
{
$sessID = mysql_real_escape_string(session_id());
$hash = mysql_real_escape_string(hash("sha512", $sessID.$_SERVER['HTTP_USER_AGENT']));
$userData = mysql_fetch_assoc($query);
$expires = time() + (60 * 15);
mysql_query("INSERT INTO `active_users` (`user`, `session_id`, `hash`, `expire`) VALUES ('" . (int) $userData['id'] . "', '" . $sessID . "', '" . $hash . "', '" . $expires . "')");
header("Location: ./Dashboard.php");
exit;
}
else {
header("Location: ./index.php");
exit;
}
}
?>
页眉.inc.php:
<?php
session_start();
require("connection.php");
$user = IsLoggedIn();
if($user)
{
$expires = time() + (60 * 15);
mysql_query("UPDATE 'active_users' SET 'expires' = '" . $expires . "' WHERE 'user' = " . (int) $user . "");
}
function IsLoggedIn()
{
$sessID = mysql_real_escape_string(session_id());
$hash = mysql_real_escape_string(hash("sha512", $sessID.$_SERVER['HTTP_USER_AGENT']));
$query = mysql_query("SELECT `user` FROM `active_users` WHERE `session_id` = '" . $sessID . "' AND `hash` = '" . $hash . "' AND `expires` > " . time(). "");
$data = mysql_fetch_assoc($query);
if(mysql_num_rows($query))
{
return $data['user'];
}
else {
return false;
}
}
?>
仪表板.php:
<?php
require("header.inc.php");
if($user)
{
print("Welcome to the dashboard!");
}
else {
header("Location: ./index.php");
end;
}
?>

require("header.inc.php");
?>

问题是密码和用户名都是正确的,但是当您输入它们时,它只会将您重定向到索引页面,而它应该将您重定向到 Dashboard.php
