I'm currently facing an issue with PHP session variables not being retained after a redirect. I'm hoping someone can shed some light on this problem and help me find a solution.
So here's the scenario: I have a PHP application where users need to go through a multi-step process. Each step involves submitting a form, and upon successful submission, they are redirected to the next step. Throughout this process, I'm storing some important data in session variables to maintain the user's progress and retrieve it later.
The issue arises when the user completes a step and is redirected to the next one. The session variables I set in the previous step are suddenly null or empty in the redirected page. It seems like the session is not persisting after the redirect.
I have double-checked my code, and I am using the `session_start()` function at the beginning of each page. I've also made sure to properly set and retrieve the session variables using `$_SESSION`. Interestingly, this problem only occurs after a redirect. If I stay on the same page and refresh it, the session variables are present and working as expected.
I have also confirmed that cookies are enabled in my browser, so that shouldn't be the problem either.
Is there something I'm missing here? Is there a specific configuration or setting that needs to be done to ensure the session variables persist after a redirect? I would appreciate any guidance or advice on how to resolve this issue.
Thank you in advance for your help!
