Action shop:checkout_billing_info

shop:checkout_billing_info CMS action

Defined in	/modules/shop/classes/shop_actions.php, lines 1746-1759
Author	LemonStand eCommerce Inc.

Base action for the Billing Information checkout page. This action is a part of the step-by-step checkout process. The Billing Information page is the first step of the conventional step-by-step checkout process.

Note that there is another action - shop:checkout, which incorporates all steps of the checkout process and allows to build the AJAX-driven checkout page, where all steps of the checkout process are displayed one by one on a single page. That sort of checkout process is implemented in our Demo Store. As contrasted with the shop:checkout action, the step-by-step checkout actions allows you to build a checkout process with separate pages. Also, using these actions you can customize the checkout process. For example, it is possible to skip some checkout steps and implement simplified checkout scenarios. Please refer to the Creating the One-Step Checkout article for the example of customizing the checkout process.

Watching the cart content changes

It is possible that a customer can change the content of the shopping cart during the checkout process. It can be done in a separate browser window. It is recommended to check whether the shopping content has not been changed after the checkout process started. LemonStand automatically saves the cart content identifier to the memory on the Billing address information step (the first step in the checkout process). You can place the following code in the Pre Action Code field of the Action tab of all your checkout pages, excluding the billing address information step.

if (Shop_CheckoutData::get_cart_id() != Shop_Cart::get_content_id())
  Phpr::$response->redirect('/checkout_billing_information');

The code compares the saved cart content identifier with a current identifier, and if they do not match, redirects the browser to the first step of the checkout process. Please use an actual value for the URL of the first checkout step of your online store.
