Info : Selling Site Access (Role Assignments)

Many sites often want to offer exclusive content, features, or access to users who pay a subscription fee. Drupal roles allow you to assign users of your Ubercart/Drupal website to be given a special set of permissions on your site. Depending on your implementation, you can do many things with roles. One of the most common uses is to allow users special content access (e.g. an exclusive website forum or a newsletter access). Sites like Warner Brothers's fan websites use the Ubercart Roles module to offer fan club membership for its bands. Here we will cover how to setup and use the Roles module.

Initial Setup

Enabling

Instead of creating a product that is exclusive a role product, Ubercart uses its product feature system to attach role assignment to any product. This way if you wanted to offer a tangible product as well as exclusive access to the site, you could create your standard product then attach a role assignment feature to it. To get started, enable the Roles under Administer › Site building > Modules. Check the box next to Roles and press the "Save settings" button.

Permissions

After enabling the module, the next step is to set permissions with the Roles module. Do this by browsing to Administer › User management > Access control. This form will show you all the roles on your Drupal configuration and what permissions they have. You will want to scroll down to the permissions for the uc_roles module. Here you will see one permission for "view all role expirations", this will give a user the permission to view any role expiration on anyone's user page. It is recommend that you only give this role to a site or store administrator.
