PHP 8.1 Session Not Persisting After Redirect in Slim Framework
I'm not sure how to approach I'm testing a new approach and I'm maintaining legacy code that I've searched everywhere and can't find a clear answer..... I'm working with an scenario where session data is not persisting after a redirect in my Slim Framework application. I'm using PHP 8.1 and have configured my session handling, but for some reason, the session data appears to be lost after I redirect users to another route. Here's a simplified version of what I'm doing: ```php // routes.php $app->get('/set-session', function ($request, $response) { session_start(); $_SESSION['user'] = 'john_doe'; return $response->withHeader('Location', '/show-session')->withStatus(302); }); $app->get('/show-session', function ($request, $response) { session_start(); if (!isset($_SESSION['user'])) { return $response->getBody()->write('No session data found'); } return $response->getBody()->write('Session User: ' . $_SESSION['user']); }); ``` When I access `/set-session`, I'm expecting to set a session variable, and upon redirecting to `/show-session`, I should be able to retrieve the session data. However, I keep getting 'No session data found' when I navigate to `/show-session`. I've made sure that the session cookie is being set correctly. I've also tried using `session_write_close()` right before the redirect, but it didn't help. Additionally, I confirmed that `session.save_path` is configured correctly in my `php.ini`. Is there something I'm missing in terms of session management with the Slim framework? Any insights would be greatly appreciated! My development environment is Linux. This is happening in both development and production on Ubuntu 20.04. What are your experiences with this? This issue appeared after updating to Php stable. Is this even possible? I'm working with Php in a Docker container on Windows 11. What am I doing wrong? Is there a simpler solution I'm overlooking?
