David Thomas Baker » PHP » PrestaShop | Review Price Incorrect

On the "Confirm your Payment" screen, the total amount does not show the full price (including shipping) straight away. Only on a second visit to the page does it show the full price.

To fix this I have put a redirect in place, line 89ish on /shop/order.php

                case 3:
                        if(isset($_POST['processCarrier']) OR isset($_POST['processCarrier_x']) OR isset($_POST['processCarrier_y']))
                                processCarrier();
                        autoStep(3);
                        checkFreeOrder();
                        // redirect back to self - dodgey but works
                        if(isset($_POST['processCarrier']) OR isset($_POST['processCarrier_x']) OR isset($_POST['processCarrier_y'])){
                                header("Location: /shop/order.php?step=3");
                                exit;
                        }else{
                                displayPayment();
                        }
                        break;
