PHP 8.1 Session Handling Not Retaining User Data After Redirect
I'm upgrading from an older version and I need help solving Can someone help me understand I’m experiencing an scenario in my PHP 8.1 application where user session data is not being retained after a redirect... I have a login form, and once the user successfully logs in, I'm trying to store their user ID in the session. Here’s the relevant part of my code: ```php session_start(); if ($_SERVER['REQUEST_METHOD'] === 'POST') { // Assume user authentication is done here $_SESSION['user_id'] = $authenticatedUserId; header('Location: dashboard.php'); exit(); } ``` However, on the `dashboard.php` page, when I try to access `$_SESSION['user_id']`, it is not set, and I get an empty result. I’ve checked my session configuration in `php.ini`, and it appears to be correct: ``` session.save_handler = files session.save_path = "/tmp" session.gc_maxlifetime = 1440 ``` I’ve also tried calling `session_write_close()` before the `header()` function, but that didn’t solve the scenario. Additionally, my `phpinfo()` shows that sessions are being started correctly. I verified that the session cookie is set in the browser, but it seems like the session data is lost after the redirect. Any insights on why this might be happening or what I could check next? This is part of a larger web app I'm building. My development environment is Linux. Any help would be greatly appreciated! For reference, this is a production service. I'm using Php 3.11 in this project. I'd really appreciate any guidance on this. Thanks for your help in advance! Could someone point me to the right documentation?
