Provide cc option to admin for registration confirmation

This can be done with an Event subscriber in a custom module that works similarly to the subscriber in the registration_confirmation submodule.

I need this, so I'm going to code it. Would you consider incorporating it as a submodule? I believe others might expect this feature - for example I've used https://www.drupal.org/project/social → before, where this works out-of-the-box.

Thanks @milos - if you are going to code it, should it be incorporated as an addition to the existing registration_confirmation submodule? That would make more sense to me than a new submodule. Basically it would add an admin email field to the existing form, above the subject field, perhaps with a description like "Send a copy of the confirmation to this email address". Maybe there would be a checkbox for "Send a copy to the author of the host entity" as well.

Thanks for the answer and suggestions. I agree that it makes sense to extend registration_confirmation submodule.

I believe that admin confirmation could be different from the one sent to the user quite often - on our site it contained info entered by the user into the form (whereas we sent further instructions to the user). So I'm going to create a separate message field for it. Perhaps there should be a checkbox (by default checked), allowing to send either a copy of the user confirmation message or a separate message?

This can become unwieldy - perhaps the long-term solution could be integration with https://www.drupal.org/project/message → and its ecosystem? Or maybe https://www.drupal.org/project/workbench_email → , given that there's support for workflow?

Agree that an admin needs a different confirmation vs. the registrant. Also agree this is getting too big and unwieldy - the modules you mentioned look interesting. Let me look into those and see if maybe an integration submodule, rather than more code in registration_confirmation, is a better approach. I'll research and get back on this issue within a day or two.

Looked into those modules and they are not suitable in my view - the integration paths are difficult and each has issues. For example sm has a very small install base, and message requires too many other modules as dependencies. Workbench works with content and adapting for registration would be a major effort. In short I think the best way forward for this particular need is either in a custom module, or adding to the confirmation and waitlist submodules of registration. I am comfortable with any decision you make - custom is probably slightly easier so I understand if you go that path. I promise if you do decide to take on the changes to confirmation and waitlist that I will review quickly and get your code merged as soon as practical after you submit an MR. Thanks @milos.

I agree with this.

This is a feature I'd LOVE to have and am currently working to use Rules to supplement this.

HOWEVER, maybe the solution is a little easier than this whole new module system. Could you please just add a CC field on the two pre-built e-mail notifications? It works great sending the e-mails to the users now, so just add a CC or even BCC field to the configuration to allow for a copy of the user e-mail to go to the admin (or whoever you wanted).

Could that work?

Thanks @wattdesigns, the new submodule concept is out. What is on the table is the CC you suggest - and @milos would also like the option to have a different message to an admin. If/when he submits this work, your CC will be in there, so you'll be covered. The extra message field does not complicate things so much that it puts this beyond reach.

That's great! Glad you like my idea! Thanks!
