The PopupAlerts extension allows to add popup alerts to wiki pages with an optionally specified expiration date so it can be controlled when (and if) users will see the popup again. It also has an integrated checksum-based invalidation mechanism to detect popup content change and hence reset the “already-seen” markers.

This extension was created for WikiWorks.

Installation

• Download and move the extracted PopupAlerts 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/PopupAlerts
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'PopupAlerts' );
  

• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage

{{#popupalert:some random wiki markup}}

popup will be seen once in 100 years

{{#popupalert:some random wiki markup|3600}}

popup will be seen once in one hour (3600 seconds)

Note: If you have many popups added to the page, only the first one will be taken into account. This limitation was added intentionally to prevent wiki pages from being spammed with popups.
