Sessions Not persisting on page change !

It sounds like you're having trouble with PHP sessions not persisting across page loads. Here are a few things you should check to troubleshoot this issue:

1. Session Start: Ensure that session_start() is called at the beginning of every PHP script where you want to access or set session variables. It must be called before any output is sent to the browser.

2. Cookies: Check that cookies are enabled in your browser since PHP sessions typically use a cookie called PHPSESSID to maintain the session state across different pages.

3. Session Configuration: Verify your php.ini file for the session configuration settings. Look for session.save_path to ensure that the server has write permissions to that directory. Also, check the session.cookie_lifetime and session.gc_maxlifetime to make sure sessions are not expiring too soon.

4. Output Buffering: If you're sending a header() after output has been sent to the browser, it will not work. Ensure that there is no HTML or whitespace before session_start() or before sending headers.

5. Path and Domain: If you're setting cookies with specific paths or domains, ensure that the session cookie's path and domain match your site's URL.

Here's a basic example of how to use sessions:

<?php
// Start the session
session_start();

// Set session variables
$_SESSION['user']['email'] = $email;

// Redirect to home page
header('Location: /');
exit();
?>

Make sure that you call exit() after header() to stop the script from running.

If you're still having issues, you might want to add some debugging information to your script to check the session's status:

<?php
session_start();

// Set a session variable
$_SESSION['user']['email'] = $email;

// Debugging: Dump the session to see if it's set correctly
var_dump($_SESSION);

// Redirect to home page
header('Location: /');
exit();
?>

Remember to remove the debugging code once you've resolved the issue.

If none of these suggestions solve your problem, it could be related to your specific application setup, such as the routing in routes.php. Make sure that your routes are not unintentionally destroying the session or that there isn't any middleware that could be interfering with the session.
