Trouble with PHP 7.4 and Session Persistence After Page Redirect
I'm stuck on something that should probably be simple... I'm testing a new approach and I'm experiencing an scenario with session persistence in my PHP application using version 7.4 when redirecting after a form submission. After submitting a form, I set some session variables, but upon redirecting to another page, those variables seem to reset to null. Here’s a snippet of my form handling code: ```php session_start(); if ($_SERVER['REQUEST_METHOD'] === 'POST') { $_SESSION['user_id'] = $_POST['user_id']; $_SESSION['username'] = $_POST['username']; header('Location: dashboard.php'); exit(); } ``` And on the `dashboard.php` page, I have: ```php session_start(); if (isset($_SESSION['user_id'])) { echo "Welcome, " . $_SESSION['username']; } else { echo "You are not logged in."; } ``` After I submit the form, I see the "You are not logged in." message on the dashboard page, indicating that the session variables are not being carried over. I've tried using `session_regenerate_id(true);` before setting the session variables and ensured that cookies are enabled in my browser, but the scenario continues. I also checked that `session.save_path` is correctly set in `php.ini`, and I'm not seeing any errors in the logs. Any suggestions on what might be going wrong here? I appreciate any insights! What am I doing wrong?
