Question

我有cookie设置，可以在控制台中看到它。当我关闭浏览器并重新打开它时，它会显示cookie仍然存在，但不会显示会话。所以我试图了解为什么我的代码没有让用户登录。我将提供下面所需的所有文件。

编辑：我应该详细说明一下。因此，当用户关闭他/她的浏览器时，会话应该不再存在，但cookie应该就是这样。所以一旦发生这种情况，我想说好，因为有一个cookie，我们将抓住该用户的cookie在数据库中查找并检索他们的ID。然后使用会话表中的id从users表中查找id并将该用户登录到。

的login.php：

<?php
require_once 'core/init.php';
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();

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

        if($login) {
          Redirect::to('index.php');
        } else {
          echo '<p>Sorry, logging in failed</p>';
        }
      } else {
        foreach($validation->errors() as $error) {
          echo $error, '<br>';
        }
      }
  }
}
?>

<form action="" method="post">
  <div class="field">
    <label for="username">Username</label>
    <input type="text" name="username" id="username" autocomplete="off">
  </div>

  <div class="field">
    <label for="password">Password</label>
    <input type="password" name="password" id="password" autocomplete="off">
  </div>

  <div class="field">
    <label for="remember">
      <input type="checkbox" name="remember" id="remember">Remember Me
    </label>
  </div>

  <input type="hidden" name="token" value="<?php echo Token::generate(); ?>">
  <input type="submit" value="Log In">
</form>

的init.php：

<?php
session_start();
$GLOBALS['config'] = array(
  'mysql' => array(
    'host' =>  '127.0.0.1',
    'username' => 'root',
    'password' => 'root',
    'db' => 'register_login'
  ),
  '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();
  }
}
 ?>

User.php：在公共功能登录下的这个文件中，我把echo＆＃39; ok＆＃39;和echo＆＃39; not ok＆＃39;看看我是否正在通过而且我得到了“没有问题”，所以if不是真的。所以我最好的猜测是$ this-＆gt; exists（）传递false。它不应该传递虚假。

用户点击“记住我”复选框后，会话未设置
