Registration system for Drupal 7 using Commerce

2 minutters læsning

Registration system for Drupal 7 using Commerce I needed a registration system for the Danish Folk Highschool, Vejle Idrætshøjskole, where you could register for the short courses and the lectures. I wanted the users to be able to pay their registrations online, so I choose Drupal Commerce which support a lot of the needed goodies out of the box.

Ditched the registration module

However, I needed some extra information about the registrants. First, I built the entire system using the registration and commerce_registration module. However, each registrant needs an e-mail in those modules. A lot of my registrants are married couples, which share an e-mail, or children which does not have an e-mail.

Used custom line items

So instead I chose to use some custom line items using the commerce custom product module. I followed a screencast about the module on and I setup the needed custom product types and custom line item types to cater for my needs. You can see the entire code at By just doing that, I have a usable registration system, which is very easy to extend because it is just based on creating new product types and line item types. I also created some custom views to view the registrants, and I am planning on using views_send to make it possible to e-mail my registrants at once and with an easy interface.

Only allow the user to register for one item at a time

I altered the add to cart form a bit, so the registrant is only allowed to register for one item at a time. Each registration can have as many registrant as possible, but one registration can not have more courses or lectures. They have to start a new registration, if they want that. Inspired by an article about a similar need I altered the add to form cart with the code, you can find at our public github.

Heavily inspired my Commerce Kickstart

I still need to make some modifications to the flow - and I am heavily inspired by the really great commerce kickstart distribution. I still need to figure out:

  • add the price on the product attribute, so the user do not have to wait for the ajax to do its magic. I was hoping that this article where I revised the code slightly on this gist, was the answer, but could not get it to work.
  • how to have different flows depending on the product type in the cart - I have lectures and short course, but soon I will also have long courses.
  • how to make the best backend for the system to make it really easy for our office to administer the registrations
