The DismissableSiteNotice extension allows users to close the sitenotice, using cookies. When you add a new sitenotice and want everyone to see it, change the number on the created page MediaWiki:Sitenotice id by one (e.g. if it would be 5, you'd replace the page with the number 6 and so on).

Download

You can download the extension directly from the MediaWiki source code repository (browse code). You can get:

One of the extensions tags

Not all extensions have tags. Some extensions have tags for each release, in which case those tags have the same stability as the release. To download a tag

• Go to the tags list
• Click the name of the tag you want to download
• Click "snapshot"

The latest version of one of the extensions branches

Each extension has a master branch containing the latest code (might be unstable). Extensions can have further branches as well.

• Go to the branches list
• Click the branch name
• Click "snapshot"

A snapshot made during the release of a MediaWiki version.

This might be unstable and is not guaranteed to work with the associated MediaWiki version.

• Download snapshot

After you've got the code, save it into the extensions/DismissableSiteNotice directory of your wiki.

If you are familiar with git and have shell access to your server, you can obtain the extension, with all its tags and branches, as follows:

cd extensions
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/DismissableSiteNotice.git

Installation

• Download and extract the files in a directory called DismissableSiteNotice in your extensions/ folder. If you're a developer and this extension is in a Git repository, then instead you should clone the repository.
• Add the following code at the bottom of your LocalSettings.php:

require_once( "$IP/extensions/DismissableSiteNotice/DismissableSiteNotice.php" );

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

Usage

How to auto-reset dismissal after every edit to MediaWiki:Sitenotice

The default is that it will remember the dismissal by the user and only reset after the number in MediaWiki:sitenotice_id has been raised. This allows a wiki to make minor updates to a notice without causing it to show again for everybody.

Some sites may not need this additional control and may want to reset it no matter the change. The below code change will reset ("re-display") the sitenotice whenever the MediaWiki:Sitenotice message is edited. This eliminates the need for the "sitenotice_id" message entirely.

In DismissableSiteNotice.php change the one line of extension code:

$id = intval( $wgMajorSiteNoticeID ) . "." . intval( wfMsgForContent( 'sitenotice_id' ) );

to:

$id = intval( $wgMajorSiteNoticeID ) . "." . crc32( wfMsgForContent( 'sitenotice' ) );
