Question

consider this problem

1. In step 1 user selects a product i am storing $_SESSION['id'] = 55;
2. Now user moves to step 2 and opens another product in a new tab.
3. Now moves to that tab It's now step 1 for the product2
4. Now $_SESSION['id'] is set 56;
5. User moves tab 1 and continues to step 3
6. But now $_SESSION['id'] = 56 and not 55

How can i prevent this. This is a cooked up problem so would like a generalized solution.

Answer 1

Sessions are site wide, so if you change the same session in one tab, it will be changed in the others. That is why sessions are used for site wide logins, as they don't change from window to window.

You should look into using Cookies or multiple sessions, but you cant change the same sessions on a tab by tab basis.
