Solution

That's probably because $pesanan is empty so the program doesn't read inside if (!empty($pesanan) and $pesanan_details becomes undefined because you don't declare it anywhere except that statement. Please make sure you have data in $pesanan or you need to handle if $pesanan also empty. Maybe in else statement like $pesanan_details = null;

Semoga membantu bang
