User Referral for Drupal 7

Integration with the Forward module shouldn't be too tough.

Looking at the forward module code, there is no way to hook into the process that determines the URL that is included in the email. It looks like it would be easy to do, but we need explicit changes to the forward module to even have a chance of integration. If someone wants to open up a ticket in their queue, go right ahead.

We need a "module_invoke_all" call somewhere in the "forward_node_view" function so we could modify the forward URL.

In line 1100 of the rc3 of the drupal 7 version of forward:

$form_state['values']['path'] = 'node/' . $node->nid;

I assume it would need to be right after that line.

UPDATE:Actually, we should be able to just use node_view_alter. Nevermind.

Ok, I've almost got everything working, including Forward module support (although its rudimentary).

I am going to start working on Rules integration, but will probably try to get the basics up pretty soon.

I will be uploading everything into my sandbox over the weekend. It's done with some good rules integration.

Everything you could do with the basic module is now ported to Drupal 7, plus with rules you can:

- Act on the event of a new referred user being saved
- Check if a referral is flagged
- Check if a user was referred by a another user
- Flag a referral
- Unflag a referral
- Set a new referral
- Change a referring user

So while native Userpoints integration is no longer here, it will be easy to implement with Rules.

Eventually I will do another module that integrates into Referral and the new Drupal Commerce to create a very basic affiliate system.

But next up will be Views integration and adding the relation to User based views.

You can view the sandbox project and even download it at http://drupal.org/sandbox/jazzdrive3/1158364

I will contact kbahey and see if he can put the code in a new 7.x branch.

The first beta has been released.

Please open new issues for additional feature requests.
