Customizing checkout with additional fields

[ArloL]

Hey guys,

I am trying to customize the existing checkout by adding two additional string inputs that the user has to fill out. I couldnt really find any information/documentation pointing me in the right direction. Does anyone else have an idea where I can find some info?

Thanks in advance!

You can look into "com.mycompany.controller.checkout" package to make changes. In this package you will find classes which has entry point of checkout actions.

Thanks prabhat.kataria. I had already looked there but didn't find something helpful.

Nonetheless I found a solution:

I extended OnePageCheckoutProcessor to include another CheckoutSectionViewType. Add a VehicleInfoForm holding the values for the new form and added a partial in templates/checkout/partials/vehicleInfoForm.html. This I also included in checkout.html. I had to add a @ModelAttribute("vehicleInfoForm") VehicleInfoForm vehicleInfoForm to all methods where the other forms where parameters in CheckoutController and BillingInfoController. Make sure it's not the last parameter.

I then added another method to CheckoutController:

@RequestMapping(
value = "/checkout/savevehicle",
method = RequestMethod.POST)
public String saveVehicleDetails(
HttpServletRequest request,
Model model,
@ModelAttribute("shippingInfoForm") ShippingInfoForm shippingForm,
@ModelAttribute("billingInfoForm") BillingInfoForm billingForm,
@ModelAttribute("giftCardInfoForm") GiftCardInfoForm giftCardInfoForm,
@ModelAttribute("orderInfoForm") OrderInfoForm orderInfoForm,
@ModelAttribute("vehicleInfoForm") VehicleInfoForm vehicleInfoForm,
BindingResult result) throws ServiceException {
Order cart = CartState.getCart();

vehicleInfoFormValidator.validate(vehicleInfoForm, result);
if (result.hasErrors()) {
return getCheckoutView();
}

OrderAttribute vehicleIdentification =
getOrderAttribute(cart, "vehicleIdentification");
OrderAttribute numberPlate = getOrderAttribute(cart, "numberPlate");

try {
vehicleIdentification.setValue(vehicleInfoForm
.getVehicleIdentification());
numberPlate.setValue(vehicleInfoForm.getNumberPlate());
orderService.save(cart, false);
} catch (PricingException pe) {
LOG.error(
"Error when saving the vehicle identification for order confirmation to the cart",
pe);
}

return getCheckoutPageRedirect();
}
