session in view file

How to get session value in view file In CI4?

Something like this:

PHP Code:

// IN CONTROLLER:
<?php
namespace App\Controller;

use CodeIgniter\Controller;

class My_Controller extends Controller
{
     private $session = null;
     public function myMethod() {
          $this->session = session();
          $data['get_sess'] = $this->session->get('item');
          echo view('folder/template', $data['get_session'])
     }
}
// IN VIEWS:
<?= $get_session; ?>

Session documentation: Link

Hello,

You have 2 possibilities, it depends upon the number of variables of your session you want to transfer.

1. In the view code directly

The context ($this) is an instance of the View class --> you don't have access to the Session instance directly.

You have to write a bit of code in the View:

PHP Code:

$session = \Config\Services::session();
// then you use the way you want to retrieve the attribute you need (see the doc) 


2. Controller code + view code
You can also pass the data during the call of the view() method in the Controller.

PHP Code:

<?php
namespace App\Controller;

use CodeIgniter\Controller;

class My_Controller extends Controller
{
     protected $session = null; // use protected instead as recommended

     public function myMethod() {
          
          // We retrieve the Session class
          $this->session = Services::session();

          // We set some data
          $this->session->item = 'Pouet';

          // We pass (only) session data to the View
          echo view('folder/template', $this->session->get());
          
          // or:
          //echo view('folder/template', ['item' => $this->session->get('item')]);
     }
} 


Then, in the view:

PHP Code:

<?= $item ?>

Should work

I prefer method 2, it is more about separating Controller and View from a purpose point of view.
