    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

    The problem is in check_out controller, before the if you most define your variable as null. it’s because if your if returns false, the variable defined before and you compact will work okay, but else, the variable is not define and returns to you this error.

    resolved code:
    public function check_out(){
        $pesanan = Pesanan::where('user_id', Auth::user()->id)->where('status',0)->first();
        $pesanan_details = null;
        if(!empty($pesanan))
        {
            $pesanan_details = PesananDetail::where('pesanan_id', $pesanan->id)->get();
        }

        return view('checkout.check_out',compact('pesanan','pesanan_details'));
}
