How to display remaining available spots for an event on the public page

Question

We need to display how many spots are left for registration on the public event registration page. Is there a way to do this?

Answer 1

If you haven't done this already - I recommend customising the template. I have experience of doing this. You'll want to create a templates override file, and then embed some PHP that accesses the remaining places. It's fairly straightforward. If you want me to go into more details then please message me!

There was an old recipe at https://civicrm.org/blog/chrischinchilla/displaying-remaining-participant-slots-on-events saying

{crmAPI var="ParticipantS" entity="Participant" action="get" sequential="1" event_id=$event.id }
// Gets the current particiapnst registered for the event

{* $x=$event.max_participants, $y=$ParticipantS.count *}
// Assigns our variables for the calculation below

Remaining - {math equation="x - y" x=$event.max_participants y=$ParticipantS.count}
// Subtract the current particpants from the maximum.
