Question

I have this session variable which i am trying to set to an access level when the users logs in with this:

Answer 1

Two possibilities here :

1. Start the session by using session_start(); at the begining of page.

2. use the following code:

   $accessquery = mysqli_query($conn, "SELECT roleid FROM person WHERE email = '". $email ."'", mysqli_store_result($conn));
   
   $access = mysqli_fetch_row($accessquery);
   
   $_SESSION['Access'] = $access[0];
