Add to cart $_SESSION has been destroy after logged in

Question

Why my $_SESSION["products"] has been destroy after logged in, How do I keep my $_SESSION["products"] after I logged in?

Add product to cart before logged in.

After logged in my cart is empty.

CODE

login.php

login( $_POST );
            if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']){
                header('Location: home.php');
            }
        } catch (Exception $e) {
            $error = $e->getMessage();
        }
    }
    if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']){
        header('Location: home.php');
    }
?>

looks like $_SESSION = $data; may be your culprit, you're resetting the entire session variable with data.

EDIT

Where $_SESSION = $data is change it to this;

$data["products"] = $_SESSION["products"];
$_SESSION = $data;

Add to cart $_SESSION has been destroy after logged in
