Works with CiviCRM 4.7 and should work on CiviCRM 5.0 or higher


CiviCRM extension granting access for event creators to view or edit their events' participants.

Why would you need this extension?

This extension is only needed if you have users who create events but who do not have permission to view or edit all the participant contacts of those events. I.e. the event creators do not have "view all contacts" or "edit all contacts" permission and do not have permission via ACLs (access control lists) to view or edit all the relevant contacts.

What does this extension do?

It implements two new permissions: 'view my event participants' and 'edit my event participants'. These grant the user access to all the contacts who are participants of events that were created by the user.

N.B. If other ACLs are in place, e.g. through CiviCRM's "Manage ACLs" user interface, then this extension allows access to the user's events' participants in addition to the contacts permitted by these other ACLs. Consider whether this is what you want: in some use cases, you might instead want to grant access to view/edit only the participants who are also permitted by the other ACLs.

E.g. suppose there's an existing ACL that gives a user access to all contacts with a UK address. With this extension, that user would have access to all UK contacts plus all participants of events created by the user - even if those participants are outside the UK.

Note: access is granted by means of a hook. Consequently this will not show up in the CiviCRM user interface under Manage ACLs: it's done "under the hood".

How do I use it?

  1. Install the extension. Currently this extension is not available for automated distribution through CiviCRM's Extension management screen and so must be manually downloaded onto the server, from and unpacked into your CiviCRM extensions directory. See .
  2. Enable the extension. From the CiviCRM menu, go to Administer -> System settings -> Extensions. Click the Enable link for View Event Participants (org.civicrm.vieweventparticipants).
  3. Grant permissions. In your CMS's permissions management screen, grant the 'view my event participants' or 'edit my event participants' permissions to the users/roles who need to be able to view/edit their event participants.


This is a new extension but has undergone extensive testing, including a pretty comprehensive suite of unit tests. So I have marked it as Work In Progress and Beta. It has been tested on a local development installation and on a test copy of a large site and no problems have so far been encountered.

If you use this extension, I'd be interested to hear your feedback, both good and bad. If you find a bug, please log an issue at . If you use it and don't find bugs, do let me know that it is working OK for you, so that we can progress towards considering it stable - davej at
