Event attendee threshold / limit notification

I want to be notified when a event reaches a certain threshold or limit. Say there’s 50 seats available I want to get notified via email when 40 people have registered.

I’ve browsed through the code but find no action hook that I can utilize for this purpose.

For example, after a user registers for an event, a check should run and see how many spaces are left and if it’s < 10, send an email.

I can write the code, I just want the best place to hook this in.

I’ve thought about putting it somewhere in the includes/process-registration/add_attendees_to_db.php file. But what about when I edit the attendee in the back end?

Ideally I don’t want to touch any core files but just a hook in there, somewhere.

Am I overlooking something?

I’m using Event Espresso is and WP version 3.5.2

Thanks in advance for any help!

What about the hook? You could check what the attendee count is and then email you if its too low.

Hi Dean

Thanks for helping.

I have setup EFT- and a custom payment method and it seems to be working for both.

However, this doesn’t work for free events. I guess that is fine for now because I don’t think there’ll be free events in the near future.

Is there anyway to do this for free payments?

Thanks again for your help!

Hi Renier,

If you want to do something similar for free events there’s a template file where you can add your code or even another do_action hook. If you look in /templates/payment_page.php where it checks for the $total_cost and if it’s 0 where it displays some information, that’s a place where a do_action could be added.

We’re adding some hooks there for the .37 release as well.

There’s also the ‘action_hook_espresso_save_attendee_data’ hook in add_attendee_to_db.php that gets called every time an attendee is saved to the db.
