使用会话保持用户登录

Question

我在试图弄清楚如何通过点击“记住我”复选框让用户保持登录状态时遇到问题。 一旦选中“记住我”复选框并且用户成功登录，我所使用的系统就会将用户的 ID 和哈希值插入到名为users_session的数据库中。

现在我遇到的问题是检查存储哈希的 cookie 是否与允许用户自动登录的哈希/user_id 相同。下面标记为登录代码的代码，您可以看到我尝试检查的地方散列匹配，但它抛出此错误Fatal error: Using $this when not in object context in此行的Fatal error: Using $this when not in object context in ， if($this->data()->password === Cookie::get($cookieName)){ .

有没有人看到我做错了什么，我无法让用户保持登录状态？

session_start();

$GLOBALS['config'] = array(
    'mysql' => array(
        'host' => 'localhost',
        'username' => '',
        'password' => '',
        'db' => ''
    ),
    'remember' => array(
        'cookie_name' => 'hash',
        'cookie_expiry' => 604800
    ),
    'session' => array(
        'session_name' => 'user',
        'token_name' => 'token'
        )
    );

    spl_autoload_register(function($class) {
        require_once 'classes/' . $class . '.php';
    });

    require_once 'functions/sanitize.php';

    if(Cookie::exists(Config::get('remember/cookie_name')) && !Session::exists(Config::get('session/session_name'))) {
        $hash = Cookie::get(Config::get('remember/cookie_name'));
        $hashCheck = DB::getInstance()->get('users_session', array('hash', '=', $hash));

        if($hashCheck->count()) {
            $user = new User($hashCheck->first()->user_id);
            $user->login();
        }
    }

创建登录/存储烹饪的代码

if(Input::exists()) { 

if(Token::check(Input::get('token'))) { 

$validate = new Validate(); 
$validation = $validate->check($_POST, array( 
    'username' => array('required' => true), 
    'password' => array('required' => true) 
)); 

if($validation->passed()) { 
$user = new User();
$cookieName = Config::get('remember/cookie_name'); //added

if(Cookie::exists($cookieName)) {  //added *********
if($this->data()->password === Cookie::get($cookieName)){  //added
echo $logged = '<span class="signinpanel">' . "You've been automatically logged in." . '</span>'; //added
}
else {
echo $logged = '<span class="signinpanel">' . "You could not be automatically logged in." . '</span>'; **strong text**
Cookie::delete($cookieName); //added
}
} 
else { 

$remember = (Input::get('remember') === 'on') ? true : false; 
$login = $user->login(Input::get('username'), Input::get('password'), $remember); 

}
if($login) { 
Redirect::to('/account/home'); 
} else { 
echo $tryagain = '<span class="signinpanel">' . "The information you entered did not match our records." . '</span>'; 
} 

} else { 
foreach($validation->errors() as $error) { 
echo $error, '<br>'; 
} 
} 
} 
}

形式

<form name="Sign In" action="" method="POST" autocomplete="on" accept-charset= "utf-8">
        <div class="field"> 
            <label for="username">Username</label>
            <input type="text" name="username" autocomplete="on" required>
        </div>
        <div class="field">
            <label for="password">Password</label>
            <input type="password" name="password" autocomplete="off" required>
        </div>  
        <div class="field"> 
            <label for="remember">
            <input type="checkbox" name="remember" id="remember"> Remember me
            </label>
        </div><br>
        <input type="hidden" name="token" value="<?php echo Token::generate(); ?>">
        <input type="submit" value="Sign In"> 
    </form>

你不能在类之外使用 $this->data() 。
