How to start session globally?

Personally, I'd put it in a library of some sort. Whatever models you're pulling results from will already have the db connection, and the library would just compile the stats from the different models.

My suggestion: don't worry about loading the session globally. First - that means that if the session isn't needed it isn't loaded which can be good for performance and some security things, IIRC. Second - whenever you first call the service, or use the the service() helper method, the session will be automatically initialized and ready for use.

Code:

// These all ensure session is initialized:
$session = \Config\Services::Session();
session('key');
session()->get('key');
session()->set('key', $value);

In CI3 the session was held globally.
I have started the session in BaseController and assigned the values to the respective one from one controller, but when evaluating it in another controller the values do not exist.

PHP Code:

//BaseController
$this->sesion  = \Config\Services::session(); 


Controller where I assign the values to the logged in user session:

PHP Code:

$datosEnSesion = array(
 'usuario'=>$usuarioEncontrado->usuario,
 'usuario_nombre'=>$usuarioEncontrado->usuario_nombre,
 'usuario_estado'=>$usuarioEncontrado->usuario_estado,
 'chequear'=>true,
 'MenuUsuarioLogueado'=>$MenuUsuarioLogueado,
 'ids_modulo_opciones'=>$ids_modulo_opciones
 );
 
//agrego los datos a una sesion
$this->sesion->set($datosEnSesion); 


If I print those values on the current controller, it works correctly, but when evaluating them on another controller, it no longer exists.
Other controller:

PHP Code:

public function __construct(){
 //parent::__construct();
 //establezco la zona horario par El Salvador
 date_default_timezone_set('America/El_Salvador');
 //comprobamos si el usuario está logueado
 
 $this->sesion = session();
 if($this->sesion->chequear != true)
 {
 //si no estoy logueado que me envie a index
 return redirect()->to(base_url());
 }
 
 
 } 


Any idea why that happens?

I looked at the documentation, https://bcit-ci.github.io/CodeIgniter4/l...-a-session, which says,

Code:

To access and initialize the session:

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

Am I supposed to put this code in the constructor of every Controller class where I need to manipulate session data?

I found that I can also use start session using this helper

Code:

session()->start();

but again I need to declare that in all files before I can use session.

I need to know the same for db and custom common functions helper file.

$db = \Config\Database::connect();

All I am trying to find out if I should be placing these in a common file? Or perhaps, declaring in each file is the suggested practice???

Regards.
With the DB connection you better use functions in your controllers and models.
The helpers use them for external libraries of a third party that do not need connection to the DB.

If I print those values on the current controller, it works correctly, but when evaluating them on another controller, it no longer exists.

 $this->sesion = session();
 if($this->sesion->chequear != true)
 {
 //si no estoy logueado que me envie a index
 return redirect()->to(base_url());
 }
 
 
 }

Does the above class extend BaseController? You MUST uncomment the line

PHP Code:

//parent::__construct(); 


Because if that does not run then the BaseController does not get to run this line

PHP Code:

//BaseController
$this->sesion  = \Config\Services::session(); 


In the example above you also do this

PHP Code:

$this->sesion = session(); 


Don't do that!

$this->sesion should be set up by BaseController and so is ready for use.

It is correct that class extends from BaseController, I have commented the line parent ::__ construct () because if it does not throw me the error of: Cannot call constructor

PHP Code:

namespace App\Controllers;
use App\Models\Modeloejemplo;
class Demo extends BaseController
{
public function __construct(){
 //parent::__construct();
 //establezco la zona horario par El Salvador
 date_default_timezone_set('America/El_Salvador');
 //comprobamos si el usuario está logueado
 $this->sesion = session();
 if($this->sesion->chequear != true)
 {
 //si no estoy logueado que me envie a index
 return redirect()->to(base_url());
 }
 
 
 }
} 


Also, if I do not declare

PHP Code:

$this->session = session(); 


the error throws me making a point that the session property is not defined

PHP Code:

namespace App\Controllers;
use App\Models\Modeloejemplo;
class Demo extends BaseController
{
public function __construct(){
    parent::__construct();  // <<< YOU MUST CALL THIS!! 


If calling that causes an error you must figure out why and fix it.

PHP Code:

namespace App\Controllers;
use App\Models\Modeloejemplo;
class Demo extends BaseController
{
public function __construct(){
    parent::__construct();  // <<< YOU MUST CALL THIS!!

That is not possible, the BaseController class does not have its own constructor, so there is no explicit constructor that can be invoked.

Oh... Right.
Never mind.

This is how I set up sessions on my BaseController.

PHP Code:

use CodeIgniter\Controller;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;

use Psr\Log\LoggerInterface;

    protected $helpers = [
        'auth',
        'utility',
    ];

    /**

    protected $session;

    /**

     */
    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
    {
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);

        //--------------------------------------------------------------------
        // Preload any models, libraries, etc, here.

        // Ensure that the session is started and running
        if (session_status() == PHP_SESSION_NONE)
        {
            $this->session = Services::session();
        }
    }

}   // End of Class BaseController.

See if that will work for you.

Just call it like this:

PHP Code:

$this->session;
