I'm currently facing an issue with PHP sessions and I'm hoping someone here can help me out. I have a session variable that seems to be empty even though I have already set a value to it.
Here's the scenario: I have a login form where users enter their credentials. When the login is successful, I set a session variable called "user_id" to the corresponding user's ID. After redirecting to the home page, I expect to see this session variable containing the ID. However, when I try to access it on the home page, it appears to be empty.
I have made sure that I am calling `session_start()` at the beginning of both the login page and the home page. I have also double-checked that the session variable is indeed being set correctly after a successful login.
Here's a simplified version of my code:
On the login page:
$_SESSION['user_id'] = $user_id; // where $user_id is the ID of the logged-in user
On the home page:
echo $_SESSION['user_id']; // This prints nothing
I have tried a few things to debug the issue. Firstly, I checked if the session is being destroyed or regenerated somewhere, but I couldn't find any such code in my application. Secondly, I tried printing out the whole `$_SESSION` array on both pages, and interestingly, other session variables are present except for the `user_id`.
I'm not sure what I might be missing here. I appreciate any insights or suggestions to help me solve this problem. Let me know if you need any additional information.
Thanks in advance!
