I need an email registration system only in my drupal site.

I installed the module email_registration and I created a module like this http://www.grasmash.com/article/using-your-email-address-your-drupal-username to set the username like the own email address.

Now my user has: name: [email protected] email: [email protected] But if the user changes is email address the username doesn't update. So if [email protected] changes his email to [email protected] the username remain the same.

I tried to update the username by the Set a data value of Rules module After updating an existing profile but I dont know how set this action... Can you help me??

You can look at this: https://api.drupal.org/api/drupal/modules%21user%21user.module/function/user_save/7

It will run after a user is created and if a user is edited. You can update the data as required.

  • But in this way I have to write a module? It's not possible do it by rules?

  • you can do it in your theme's template.php file. doing it via Rules would be even more complex in my opinion.
