cakephp 3.x updating user data - php

Question

I have written a basic login script and now need to update the data stored in the auth component and then save it to the database, this is what i have so far;
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.'));
}
}
I've tried a few different variations but can't get any to work. Any ideas?

Answer 1

Updating data in cakephp3 is slightly different than cakephp2, Try something like this:
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.'));
}
}
Another way of updating record in cakephp3 is:
$query = $this->Users->query();
$query->update()
->set(['last_activity ' => date('Y-m-d')])
->where(['id' => $user['id']])
->execute();
But I don't recommend this one as callbacks are not fired.

In Cake3, you can take advantage of the afterIdentify event.
In AppController::initialize, add a listener for the event:
\Cake\Event\EventManager::instance()->on('Auth.afterIdentify', [$this, 'afterIdentify']);
Add AppController::afterIdentify function to handle the event:
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);
}
Now, the data returned by the Auth->user() call should always be up-to-date without any extra effort on your part.
