I'm facing a bit of a problem with my PHP sessions and I'm hoping someone can help me out. So here's what's happening:
I have a website with a multi-step form where users can fill in their information. I'm using sessions to store the data entered by the users, so that they can navigate between the form steps without losing their progress. Everything is working fine except for one issue: whenever a user goes back to a previous step/page, all their session variables are lost.
For example, let's say I have Step 1, Step 2, and Step 3. If a user completes Step 1, moves on to Step 2, and then decides to go back to Step 1, all the data they entered in Step 1 gets wiped out.
I've checked my code, and I'm using the session_start() function at the beginning of each PHP file that handles the form steps. I'm also using session variables to store the data like $_SESSION['variable_name'] = $value.
I've also confirmed that cookies are enabled in my browser, so that's not the issue. I've also tried different browsers, but the problem persists.
I'm not sure what could be causing this problem. Could it be something in my PHP configuration? Or am I missing something in my code? Any help or suggestions would be greatly appreciated.
