PHP's single-page checkout. I covered the product gallery and the whole cart movement in a single page. This is a simple script.
The product tiles will be displayed in the gallery with an add-to-cart option. The inserted cart items will then have editing and deletion options.
To accomplish the cart operations, I utilized jQuery AJAX to request the server-side code.
In addition, the cart detail table will include a preview for confirmation prior to checkout. Customer name and email address are required for the checkout process.
