我正在开发一个网站,但我的登录系统有问题。考虑两个用户,user1 和 user2。如果 user1 可以访问他的帐户,并且在同一个浏览器中,如果 user2 可以访问他的帐户,则 user1 必须从他的会话中注销,但这在我的系统中不会发生,此外,系统认为 user1 是 user2,因为 user2已连接。这是登录页面和身份验证的以下代码:
登录代码
<html>
<body>
<div class="wrap">
<div id="content">
<div id="main">
<div class="full_w">
<form action="login_oficial.php" method="post" autocomplete="off">

<input id="login" name="login" class="text" />
<label for="pass">Contraseña:</label>
<input id="pass" name="pass" type="password" class="text" />
<input type="submit" class="ok" name="acceso_cuenta" value="Acceder"></button>
</form>
</div>

session_start();

$_SESSION['user']=$usuario;
$error = '';
$form = $_POST['acceso_cuenta'];

$query1 = "SELECT user FROM data1 WHERE user='$usuario' and passwort='$password'";
$result=pg_query($conn,$query1);
if( isset($form) ) {
if( isset($usuario) && isset($password) && $usuario !== '' && $password !== '' ) {
if(pg_num_rows($result) != 0 ) { //success
$_SESSION['logged-in'] = true;
header('location: http://localhost/public_html/website/normal_user.php');
exit;
}else { $error = "Your information is wrong."; }
} else { $error = 'Please, do not leave blank spaces.';}
}

用户页面
<?php

// is the one accessing this page logged in or not?

// not logged in, move to login page

注销.php
session_start();
// if the user is logged in, unset the session
if (isset($_SESSION['logged-in'])) {
unset($_SESSION['logged-in']);
}
// now that the user is logged out,
// go to login page
header('Location: login.html');
