Autogenerate username from user id

I would like to prevent users from choosing their own username. Rather, I would like it to be auto generated from their user id. I have created a field cb_usertype that is used to assign users to a specific user group (as per your tutorial).

If the user is usertype = 1, I would like to generate a username that is the userid prefixed by the letter "h" (i.e., username = h1284 where 1284 is the user id).

If the usertype = 2, I would like to generate a username that is the userid prefixed by the letter "w" (i.e., username = w2395 where 2395 is the userid). I would need for this username to be included in the email verification notice that is sent to the user. Is this possible with Auto Action? I have all latest CB and plugins as of 11 June 2015.

Set the username field to not display on registration in CB > Field Management. Next within CB > Configuration > User Profile set "Username Fallback" to "Email" so it falls back to something unique. Now using CB Auto Actions create the following action.

Triggers: onAfterUserRegistration, onAfterNewUser
Type: Field
User: Automatic
Access: Everybody
Field: Username
Operator: Set (Field = Value)
Value: h[user_id]

This should provide what you're wanting.

Thank you for this advice. Since I have 2 types of users, I need to put a condition in this action. When I set the condition to cb_usertype Equal To 1, the action should create the userid h[user_id]. Adding this condition does not seem to work. Debug shows: string(67) ":: Action 3 :: Conditional 1 failed for 454: cb_usertype Equal To 1". It seems that this action is not receiving cb_usertype data.

I have other actions that use the same condition to assign users to a user group based on cb_usertype and they are working.

I have tried also using the Does Contain in the condition, but the debug error is the same.

Actually, if I am using CB Subs as well, would it be better to do some or all of this within that plugin, including the use of SQL Actions?

The condition needs to be a valid substitution. So you'd need to use the below.

[cb_usertype] Equal To 1

See the below for further substitution usage information.

You might be able to use CBSubs CB Field to change the username.

Thank you--you are correct as I did not enclose the substitution in brackets as I had done with the other auto actions and I apologize for missing it myself and wasting your time. It now works as you said it would.

I would like to change the procedure a bit. I will use a plan specific URL to access the registration page. For example:
index.php?option=com_comprofiler&task=pluginclass&plugin=cbpaidsubscriptions&do=displayplans&plans=1

Rather than the cb_usertype that I had originally asked about, I would like to to set the username based on the plan number that was used to access the registration page. For example, if plans=1 or plans=2 then I want to set the username to be h[user_id]. And if plans=3 or plans=6 I want to set the username to be w[user_id].

How can I capture the plan number when I enter the registration page? It is available in the URL and I can see in the page source code that it is also available as a hidden field: <input type="hidden" name="cbponlyplans" value="1" />
