Applying sessions in cakephp 3.2 - cakephp

Question

Im using cakephp 3.2 to build an application. Im using the bookmarks tutorial as a basis for my project. in one of my bookmarks .ctp view files I would like to have a number of select boxes with data specific to the user loggged in. i have two tables namely users and bookmarks. My bookmarks table contains foreign key from users table user_id.
Here's my bookmark table with the fields i would like the dropdowns. id, user_id, title, systemregistration, systemroles, country, province, metropolitan.
Code for my appcontroller
namespace App\Controller;
use Cake\Controller\Controller;
use Cake\Event\Event;
/**
* Application Controller
*
* Add your application-wide methods in the class below, your controllers
* will inherit them.
*
* #link http://book.cakephp.org/3.0/en/controllers.html#the-app-controller
*/
class AppController extends Controller
{
/**
* Initialization hook method.
*
* Use this method to add common initialization code like loading components.
*
* e.g. `$this->loadComponent('Security');`
*
* #return void
*/
/*public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
$this->loadComponent('Flash');
}*/
public function initialize()
{
$this->loadComponent('Flash');
$this->loadComponent('Auth', [
'authenticate' => [
'Form' => [
'fields' => [
'username' => 'email',
'password' => 'password'
]
]
],
'loginAction' => [
'controller' => 'Users',
'action' => 'login'
],
//'storage' => 'Session'
'Session'
]);
// Allow the display action so our pages controller
// continues to work.
$this->Auth->allow(['display']);
}
/*public function initialize()
{
$this->loadComponent('Flash');
$this->loadComponent('Auth', [
'loginRedirect' => [
'controller' => 'Bookmarks',
'action' => 'index'
],
'logoutRedirect' => [
'controller' => 'Pages',
'action' => 'display',
'home'
]
]);
}
public function beforeFilter(Event $event)
{
$this->Auth->allow(['index', 'view', 'display']);
}*/
/**
* Before render callback.
*
* #param \Cake\Event\Event $event The beforeRender event.
* #return void
*/
public function beforeRender(Event $event)
{
if (!array_key_exists('_serialize', $this->viewVars) &&
in_array($this->response->type(), ['application/json', 'application/xml'])
) {
$this->set('_serialize', true);
}
}
}
//BookmarksController looks like this
namespace App\Controller;
use App\Controller\AppController;
/**
* Bookmarks Controller
*
* #property \App\Model\Table\BookmarksTable $Bookmarks
*/
class BookmarksController extends AppController
{
public function internalprotocol()
{
$bookmark = $this->Bookmarks->newEntity();
$users = $this->Bookmarks->Users->find('list', ['limit' => 200]);
$tags = $this->Bookmarks->Tags->find('list', ['limit' => 200]);
$this->set(compact('bookmark', 'users', 'tags'));
$this->set('_serialize', ['bookmark']);
$bookmarks = $this->paginate($this->Bookmarks);
$this->set(compact('bookmarks'));
$this->set('_serialize', ['bookmarks']);
}
}
//my internalprotocol.ctp looks like this
<div>
<?php echo $this->Form->input('user_id', ['options' => $bookmarks]); ?>
<?php echo $this->Form->input('title', ['options' => $bookmarks]); ?>
<?php echo $this->Form->input('systemregistration', ['options' => $bookmarks]); ?>
<?php echo $this->Form->input('systemroles', ['options' => $bookmarks]); ?>
<?php echo $this->Form->input('country', ['options' => $bookmarks]); ?>
</div>
I would like to populate each of the fields with data specific to the user logged in. Could you please help!

Answer 1

You don't need to do anything. If a login is successful you can access the logged in user details through the Auth component using $this->Auth->user();
If you need to add any more information to the session you can use the Session component like $this->Session->write('User.AscociatedData', $AscociatedData);
Easiest way to access this data in the view is to set authenticated user as a view variable in the controller:
$this->set('user',$this->Auth->user());
then you can accesses the users info in the view with $user e.g$user->fieldName
Not entirely sure what your asking but I hope one of my answers is relevant.

Answer 2

we only need to show bookmarks for the currently logged in user.
We can do that by updating the call to paginate().Make your index() action from Controller/BookmarksController.php look like:
public function index()
{
$this->paginate = [
'conditions' => [
'Bookmarks.user_id' => $this->Auth->user('id'),
]
];
$this->set('bookmarks', $this->paginate($this->Bookmarks));
$this->set('_serialize', ['bookmarks']);
}
We should also update the tags() action and the related finder method as we done for bookmarks above
