One of the most powerful things that you can do to a Drupal site is to add Drupal Commerce. With some modules and a bit of time, you can transform any Drupal 7 site into a revenue generation engine — no matter if you are selling physical products, file downloads, or just wanting to monetize digital content or access. The ability to simply enable commerce on an existing site is very powerful and can open up opportunities that you might not have considered.

One of those possibilities is paid content. This post will walk you through adding paid content to an existing blog site using two modules from our Digital Commerce Suite: Commerce License (CL) and Commerce License Billing (CLB). At DrupalCon 2014 in Austin, in the second half of Commerce by Example, we walked through the process of setting up a blog. The instructions and the demo site archive are here (link above) so you can walk through at your own pace.

Commerce Add to Cart Extras is a great little module that provides the ability to turn a product listing view into an add to cart form. It does this by providing a new field that you add to a view which provides a quantity text box and makes the entire view an add to cart form. This differs from the existing “Add to Cart” field provided by commerce, which allows you to add a single item to the cart from a list.

This allows you to do some useful things such as creating a bulk order form which lists some or all of the products on your site, allowing customers to enter a quantity directly for the products they want. Or, you can utilize standard Views functionality to create another add to cart form for wholesalers on products with several attributes allowing them to add quantities of each individual product quickly and easily. Let’s take a brief look at how we can do this.  Just download and enable the module, and you’re ready to get started.
