CampaignEvents is a MediaWiki extension, created and maintained by the Wikimedia Foundation Campaigns Team, which provides tools for organizing and running events, including registration, communication and an organizer dashboard. See Registration for more information.

Installation

• Download and move the extracted CampaignEvents folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CampaignEvents
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'CampaignEvents' );
  

• Run the update script which will automatically create the necessary database tables that this extension needs.
• Schedule a cronjob that runs the #script to update timezones (optional), and one for the #script to aggregate participant answers.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

User rights

Right	Description
campaignevents-enable-registration	Enable event registrations
campaignevents-delete-registration	Delete event registrations
campaignevents-organize-events	Organize events
campaignevents-email-participants	Email event participants

Parameters

Variable name	Default value	Description
$wgCampaignEventsProgramsAndEventsDashboardInstance	null	Determines which instance of the P&E Dashboard should be used, if any. Supported values are 'production', 'staging', or null to not use the dashboard.
$wgCampaignEventsProgramsAndEventsDashboardAPISecret	null	API secret to use with the selected P&E Dashboard instance. Must be configured if you intend to use the P&E Dashboard.
$wgCampaignEventsEnableWikimediaParticipantQuestions	true	Whether to enable Wikimedia-specific questions that can be asked to participants, such as whether they belong to a Wikimedia affiliate.

The extension can be configured to store data into a database other than the main wiki DB. You do so by configuring the virtual-campaignevents domain, see Manual:$wgVirtualDomainsMapping . For instance:

$wgVirtualDomainsMapping['virtual-campaignevents'] = [ 'db' => 'my_central_db' ];

This is especially useful in combination with a central database that stores event for a whole wiki family. Note, if you do so, that the wiki farm needs to use central user IDs .

API

Documentation of all the API endpoints is available.

Maintenance scripts

Script to update timezones

The extension stores the local time and timezone for each event, to guarantee that the local time remains accurate even if time zone rules change. However,internally it also stores UTC timestamps so that certain operations like sorting are possible. The UTC timestamps may go out of sync with the local ones if time zone rules change, which happens more commonly than you may think. You can read more details. In order to mitigate that, the extension provides a maintenance script that recomputes the UTC timestamps for all events according to the latest timezone rules, and stores them back into the database.

In order for this to work, you have to make sure that PHP has access to the latest version of the tz database. The PHP manual provides some context about this. The easiest solution is to install the timezonedb PECL package and make sure to keep it up-to-date.

Assuming that PHP has access to the latest timezone rules, you can run the script with:

$ php maintenance/run.php ./extensions/CampaignEvents/maintenance/UpdateUTCTimestamps.php

The script also takes an optional --timezone parameter where you can specify the name of a time zone whose rules changed; this parameter can be repeated multiple times. If passed, the script will only update events whose timezone matches one of the timezones specified via this parameter.

If you upgrade the time zone database automatically (e.g., with a cronjob), you can make that job also execute this script, so that you don't have to do it manually every time you upgrade the time zone database.

Script to aggregate participant answers

The extension provides a maintenance script that aggregates participant answers after a 90 day period. The script can be run with:

$ php maintenance/run.php ./extensions/CampaignEvents/maintenance/AggregateParticipantAnswers.php

The script should be configured to run automatically (e.g., as a cronjob) to make sure that PII isn't retained for longer than it needs to.
