Hello @csheantel

> I’ve been trying to understand how slim works.

You could start with this [Slim tutorial](https://odan.github.io/2019/11/05/slim4-tutorial.html) to get the basics.

Make sure, that the session is getting started for each request. For this purpose the best would be to start the session within a Middeware.

Example file: `src/Middleare/SessionMiddleware .php`

```php
<?php

namespace App\Middleware;

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Server\RequestHandlerInterface;

final class SessionMiddleware implements MiddlewareInterface
{

    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        if (session_status() !== PHP_SESSION_ACTIVE) {
            session_start();
        }

        $response = $handler->handle($request);
        session_write_close();

        return $response;
    }
}

```

Although this is not your answer but It may help you to write better code.

Fe suggestions:

1. Use a good code editor (VS Code recommended)
2. Use Code Formatter
