Selling Pay-Per-Download Products
Sunday 30 August 2009 3:00:00 pm
Before we delve into any code or even content, let's consider how we want the process to look from the buyer perspective.
- Buyer browses products and adds some to his/her online shopping cart
- Buyer initiates checkout process and is prompted to pay for the product
- Upon successful payment, buyer is presented with relevant download links on the confirmation page and in the confirmation e-mail.
This is rather straightforward from the buyer's perspective. Let's now consider what we will need to do to achieve this.
- Associate the actual downloads with products: We will do this by adding a related object attribute to one of our product classes.
- Shopping cart and checkout process: This is a built-in eZ Publish feature and we will use most of the defaults here.
- Payment process: We will install an existing PayPal payment gateway extension, making use of the eZ Publish workflow system.
- Download permissions: We will write an extension to assign permissions at checkout so that the buyer can access the files associated with the purchased products.
- Confirmation page and e-mail: We will modify existing eZ Publish templates to add the necessary download information.
