[SOLVED] CB Auto Action to create random usernames

Hi,

I've looked a little bit everywhere before asking, I'm using Auto Actions for the first time and I'm a little lost... So my first question is, is there a documentation somewhere?

My goal right now is to generate random user names when someone signs up. So obviously the user name field needs to be hidden on the registration form, and then I intend to have it generated, probably on an onStartSaveUserRegistration trigger right?
My problem is that if I do understand how to set up a condition for the action, I have no idea what to do to define the action itself... At that point I'm guessing having a small piece of JS or PHP code to generate a random string and then feed that into the user name field should do it... But how / where?

Thanks.

Seb.

Wait a minute, I think I'm progressing...
I should have selected the "code" type, right?
So I can add a small JS or PHP function to generate a random string. Now I need to figure out how to store it into the user name field...

I've chosen the PHP(eval) method (I'm more at ease with PHP than JS) and added this in it:
So I should now have a variable containing my random string... What would the next step be?

Edit: I'll also need to make sure that particular string doesn't match an existing user name of course... I'm probably going to have to call some CB internal functions (verify user name, store user name).

Please review the below topic carefully. It does exactly this except generates email addresses. The same usage can be applied to the username field.

Basically with the above you're adjusting the POST value of the username field before Joomla/CB does anything with it. It's really the only time it can be done.

This looks perfect. Thanks!

Edit: tested and working perfectly.

To check my random string against the list of existing user names, I guess I could make a direct request on the database... Is this the best way or is there a better solution?

You really don't need to check it against the database. A random 12 character username has an extremely slim to none chance of being the same as another. As you appear to want random 25 character I believe you'll be just fine. At any rate if you want to see if it already exists you'd use the below CB API to do this.
