provide a hook so other modules can help generate the user name

subscribe

I'm starting a new project which requires this type of functionality, email_registration will get some lovin' in this department over the next few weeks. Expect new release soon, need testers.

Just downloaded the latest dev release (from 1 hour after your post) - but i can't seem to find the content_profile and token support mentioned.

In the module file, I see this:

/** 
 * function email_registration_settings() {
 *  return system_settings_form($form);
 * }
 */

And no instance of content_profile anywhere in the code, just:
if (module_exists('profile') && is_array($form['account'])) {

..Do i have the right version? This is a great module which fits perfectly for a current project, i'll gladly help test this out.

Still can't get this working...

Users are getting in their emails a strange username - but on the admin pages i see the correct pre-@ usernames.

Solvable...?

The attached patch provides hook_email_registration_name($edit, $account) - by implementing this hook in a module, you can replace email_registration's default username generation with whatever you like. This operates on a case-by-case basis - in my case, I'm migrating to Drupal from a system which used email for logging in, but also had usernames - only for users who had commented. So, with this implementation, I can return the existing username when it exists, and otherwise return NULL and allow email_registration to generate a username for the rest.

Comments?

Mike, I love the idea. Patch failed?

Hmm, try this one...

Still she no go. I'll apply the changes manually and commit it when I get a minute

Suppose there's not clear solution so let's go to Hall of Shame

Thanks mikeryan, Chris.

I've now committed this to the 6.x branch: http://drupal.org/cvs?commit=223514

@andypost - I don't understand why you would post that message in this thread. I like the so called "hall of shame" but this module's existence there is not for shame - it doesn't duplicate functionality - and this issue has nothing to do with duplication (aside from the misplaced messages by asak). Poor form, sir.

So how exactly does this work now?

The auto_username module only has a 5.x release. I have also been running realname module which changes the display of the username to whatever profile fields you choose, but the actual username stays the same.

This is a hook and you have to write code to implement that hook to get it to work. The hook is:

module_invoke_all('email_registration_name', $edit, $account);

So your code would have to be something like:

function mymodule_email_registration_name($edit, $account) {
  return md5($account->mail);
}
