我为我的 Web 应用程序创建了一个登录类，它确实可以工作，但现在我创建了那个臭名昭著的“让我保持登录” - 复选框并且没有让它工作。这是我的登录课程：
<?php
error_reporting(E_ALL ^ E_NOTICE);
class Login {
private $error;
private $connect;
private $email;
private $password;
public $row;
public function __construct(PDO $connect) {
$this->connect = $connect;
$this->error = array();
$this->row = $row;
}
public function doLogin() {
$this->email = htmlspecialchars($_POST['email']);
$this->password = htmlspecialchars($_POST['password']);
$this->rememberme = $_POST['rememberme'];
if($this->validateData()) {
$this->fetchInfo();
}
return count($this->error) ? 0 : 1;
}
public function validateData() {
if(empty($this->email) || empty($this->password)) {
$this->error[] = "Täyttämättömiä kenttiä";
} else {
return count($this->error) ? 0 : 1;
}
}
public function fetchInfo() {
$query = "SELECT * FROM users WHERE email = :email AND activation_token IS NULL";
$stmt = $this->connect->prepare($query);
$stmt->execute(array(
':email' => $this->email,
));
if($stmt->rowCount() == 0) {
$this->error[] = "Väärä käyttäjätunnus tai salasana";
return 0;
} else {
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['email'] = $row['email'];
$_SESSION['name'] = $row['name'];
$_SESSION['profilepic'] = $row['profilepic'];
if(isset($this->rememberme)) {
setcookie("loggedin", "yes", time() + 25200);
}
}
if (Register::cryptPass($this->password) != $row['password']) {
$this->error[] = "Virheelliset kirjautumistiedot";
} else {
return true;
}
return count($this->error) ? 0 : 1;
}
public function displayErrors() {
if(!count($this->error)) return;
echo "<div class='login_error'>";
foreach($this->error as $key=>$value) {
echo "<p>".$value."</p>";
}
echo "</div>";
}
public function doLogout() {
session_destroy();
}
}
?>
这是我另一个文件中的一小部分代码，我正在检查是否设置了会话或cookie：
<?php
if (isset($_SESSION['email']) || isset($_COOKIE['loggedin'])) {
?>
<div id="header_container_isloggedin">
<div class="container_12">
<header id="header">
<div class="grid-12">
<ul id="menu">
<li class="profile-name">
<a href="profile.php?id=<?php echo $_SESSION['user_id']; ?>">
<span class="header_username">
<img src="images/thumbnails/<?php echo $_SESSION['profilepic']; ?>"
class="profile_evensmaller"/>
<span class="header_name"><?php echo $_SESSION['name']; ?></span></span></a>
</li>
</ul>
<?php } ?>
问题是每次设置 cookie 时，它都不会显示我的个人资料图片或姓名，因为它们已保存在 $_SESSION 变量中。那么我应该如何解决这个问题并让它发挥作用。我知道现在这不是最安全的方法，因为我没有为那个 cookie 生成任何哈希值，但现在我唯一感兴趣的是让这个方法工作。
