codeigniter 4 set session variable $session = \Config\Services::session(); globally

Question

in codeigniter 4 as per the documentation we have to load library as

$session = \Config\Services::session();

if i write it on above of controller name

<?php
namespace App\Controllers;

    $session = \Config\Services::session();

    class Home extends BaseController
    {

    }

i cant access $session variable in any function, even if i wrote it in __construct it is not accessible in any function if i write it any function then only it is working, but i wants to set it globally.

Answer 1

i solved it, as below

<?php
namespace App\Controllers;




class Home extends BaseController
{

    protected $session;


    function __construct()
    {

        $this->session = \Config\Services::session();
        $this->session->start();


    }



    public function code4()
    {

        $newdata = [
                'username'  => 'johndoe',
                'email'     => '[email protected]',
                'logged_in' => TRUE
        ];

        $this->session->set($newdata); // setting session data


        echo $this->session->get("username");

    }

    //--------------------------------------------------------------------
