cakephp 3.x 更新用户数据

Question

我已经编写了一个基本的登录脚本，现在需要更新存储在 auth 组件中的数据，然后将其保存到数据库中，这是我目前所拥有的；

public function login()
{
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();
        if ($user) {                 
            $this->Auth->setUser($user);
            $this->Auth->user()->last_activity = date("Y-m-d");
            $this->Users->save($this->Auth->user());
            return $this->redirect($this->Auth->redirectUrl());
        }
        $this->Flash->error(__('Email or password is incorrect, please try again.'));
    }
}

我尝试了几种不同的变体，但都无法正常工作。 有任何想法吗？

在 cakephp3 中更新数据与 cakephp2 略有不同，请尝试如下操作：

public function login()
{
 if ($this->request->is('post')) {
    $user = $this->Auth->identify();
    if ($user) {                 
        $this->Auth->setUser($user);
         $userData = $this->Users->get($user['id']);
         $userData->last_activity = date("Y-m-d");
         if($this->Users->save($userData)){
            $user['last_activity'] = $userData->last_activity; // to update auth component
         }
         // echo $this->Auth->user('last_activity');
         return $this->redirect($this->Auth->redirectUrl());
    }
    $this->Flash->error(__('Email or password is incorrect, please try again.'));
 }
}

在 cakephp3 中更新记录的另一种方法是：

$query = $this->Users->query();
 $query->update()
->set(['last_activity ' => date('Y-m-d')])
->where(['id' => $user['id']])
->execute();

但我不推荐这个，因为不会触发回调。

在 Cake3 中，您可以利用afterIdentify事件。

在AppController::initialize ，为事件添加一个监听器：

\Cake\Event\EventManager::instance()->on('Auth.afterIdentify', [$this, 'afterIdentify']);

添加AppController::afterIdentify函数来处理事件：

public function afterIdentify(CakeEvent $cakeEvent, $data, $auth) {
    $users_table = TableRegistry::get('Users');

    $user = $users_table->get($data['id']);
    $user->last_activity = new Cake\I18n\FrozenTime();

    // If you ever need to do password rehashing, here's where it goes
    if ($this->Auth->authenticationProvider()->needsPasswordRehash()) {
        $user->password = $this->request->data('password');
    }

    $users_table->save($user);
}

现在，由Auth->user()调用返回的数据应该始终是最新的，您无需付出任何额外的努力。
