Setting and Getting Session and Flashdata

Can anybody guide me how to set and retrieve session and flashdata?

I initialized session base controller and when I try to set and get on User controller, I am getting error saying "ErrorExceptoin": undefined variable $session when using this snippet below

PHP Code:

$session->set('user', 'someone'); 


$session = session();
$session->set('user', 'someone');

$session = session();
$session->set('user', 'someone');

Thank you, it works

Should "$session = session();" be called on each controller?

Is there any way to autoload like CI3 version?

full simple example for CI4:

PHP Code:

<?php
namespace App\Models;

use \Config\Services\session;

class My_Model
{
     private session = null;
     
     public function __construct() {
           $this->session = new session();
     }
     public function setDataSession($data) {
           // ... you code
           $this->session->set( $data );
           // ... you another code
     }
}

I would change this world, but God doesn't give me the source.

           $this->session = new session();
     }

           $this->session->set( $data );

     }
}

CI4, different with CI3.
learn about filter.

use BaseConttoller for autoload libraries, helper etc.

Yes CI4 is way different than CI3.

learning the changes was made on CI4 by applying in sample project.

Also found simple way to set and get session and flashdata. I will share my code with sample project which I am working on once its done.

Hello Bro, i have joined this community to improve my skills not for spam

The error appears because you are using CI3, I gave an example for CI4. CI4 has been rewritten and therefore they are incompatible.
If you still have errors, then describe them here, but rather best to provide logs from the folder /writable/logs/ or /writable/debug/ if they are available.
