I'd like to bulk register users without email address in my component. Afaik there isn't a database constraint, so in theory it is possible to inject the rows necessary to do this. I'd rather use the JUser class if it is possible to do the same with that. What I need from it is password hashing and username generation from the real name. Any experience with that?

Okay, I found the solution for password encryption: https://stackoverflow.com/questions/21304038/joomla-3-2-1-password-encryption

$yourpass = JUserHelper::hashPassword($password_choose);

So I just hash the password and insert the row to the users table with empty email. Adding them to some groups is just as easy by adding rows to the user_usergroup_map table. If you want the users to be able to login, you need to add them at least to the registered user group. I generated a dummy email address too, something like {username}.dummy@host just to be sure, but this solution does not send out annoying registration emails.

    I think you are a better off to insert a dummy email for each user lest you keep hitting email required warnings if you ever try to edit the user in the backend for example. Something like: [email protected] and as long as your domain's catchall is configured to discard all email then that should be fine. Commented Feb 15, 2017 at 21:25
  • @jamesgarrett Thanks James! Email is not important in this scenario. I just need around 150 users to be able to login and use a relative simple component.

  • @jamesgarrett Should I add a formally valid email, like {username}@xxx.com to avoid errors?

  • i don't think it matters if the email account exists or not if that is what you are asking. So {username}@xxx.com or [email protected] are both suitable dummy email addresses to use. I should add to be clear, if it is not obvious, that I suggesting that you generate a unique random string for each user. Commented Feb 15, 2017 at 23:36
  • @jamesgarrett I thought I just leave it empty, but okay adding a non-existent email address of the same domain cannot hurt. Is there a way to reuse the text -> dash/underscore case transformation in joomla? For example it is used by converting article titles to uris.
