Using on Frontend

“Cancelled” is nothing more than a new post status, in addition to “publish”, “pending” and “draft”, but after setting it, it executes other triggers as well. A default post status does not do that.

The front-end submission form does not allow changing of the post status, because that would mean the Admin will have no control anymore – every submitted event can be approved (published) immediately.

If you do want to let users change the post status you would have to change the submission form. And that is a question for the EM team. ??

Yes, I agree with you. But it would be great to have at least a button that triggers the Cancellation-Status. This could be realised by a shortcode. Just a proposal from my side to enhance the plugin.

I kindly disagree… ??
If there are (online) payments involved, the Admin (who is legally responsible for any refunds) has no idea the event has been cancelled. Which can result in customers not getting their money back and your company getting complaints and/or bad reviews.

I strongly believe that those kind of risks should only lie with the admin. That is also why users without the right capabilities can not publish an event.

There is no payment needed on my website. For me it would help to have such an option.

Ok, however what the purpose is, for my case I would appreciate a cancel-button for the event organisers. Can you tell me, how I can implement this?

You would have to apply custom coding to the front-end event submission form to enable setting the post status. Note that, if not coded fully, users can then also select publish, pending and draft.
That is the whole security the EM Devs have put in for a good reason.

How to edit the event submission form would be a question for the Events Manager team.
