The Comments extension adds the ‎<comments /> parser hook tag to allow commenting on articles where the tag is present.

Comment actions are logged to Special:Log/comments, but by default they're hidden, just like patrol log entries. You can set $wgCommentsInRecentChanges = true; to show comments log entries in Special:RecentChanges (available in version 2.8+).

Majority of the code fixes were done by Misza and Jack Phoenix.

Installation

• Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens Comments im Ordner extensions/ ablegen.
  Entwickler und Code-Beitragende sollten stattdessen die Erweiterung von Git installieren, mit:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Comments
• Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen:

  wfLoadExtension( 'Comments' );
  

• Führe das Aktualisierungsskript aus, welches automatisch die notwendigen Datenbanktabellen erstellt, die diese Erweiterung braucht.
•  Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.

You will need to download the master version for the extension to work properly, as there is an issue with the branched versions.

Verwendung

• ‎<comments /> — basic comment form, sufficient for most things.
• <comments allow="Derfel,Jack Phoenix,Misza" /> — only allows the users Derfel, Jack Phoenix and Misza to submit comments.
• <comments voting="Plus" /> — prevents users from rating comments negatively (thumb down), allowing only positive (thumb up) votes.

Comments of the Day

The extension also comes with a "Comments of the Day" feature (‎<commentsoftheday />), which by default is not enabled. You can enable this feature in the wiki's LocalSettings.php, by adding the following after the require_once line:

require_once "$IP/extensions/Comments/CommentsOfTheDay.php";

If the nocache argument is passed to the parser hook (like this: <commentsoftheday nocache=true />), the parser hook will not use memcached and will fetch the data from the database instead of cache. This is useful if you want to show the most up-to-date data, but it can be very server-intensive.

Benutzerrechte

Die Erweiterung fügt drei neue Benutzerrechte hinzu:

• comment - which allows posting comments
• commentlinks - which allows posting external links in comments
• commentadmin - which allows deleting user-posted comments
• comment-delete-own - which allows deleting one's own comments, e.g.

$wgGroupPermissions['sysop']['commentadmin'] = true;

By default, everyone, even anonymous users, can post comments, but posting comments that contain external links is limited to autoconfirmed users.

If you want anonymous users to be able to post external links, add this after the require_once:

$wgGroupPermissions['*']['commentlinks'] = true;

By default, only users in the commentadmin group can delete comments.

User points

This is relevant only if the SocialProfile extension is installed and $wgUserLevels is properly configured.

• $wgUserStatsPointValues['comment_plus'] — the number of points to give out when another user gives a "thumbs up" to your comment.
• $wgUserStatsPointValues['comment_ignored'] — the number of points to give out when another user adds your comments to their ignore list (Special:CommentIgnoreList).

Parameter

• $wgCommentsDefaultAvatar — the path to an image which will be displayed instead of an avatar if social tools (SocialProfile extension) aren't installed. It should be 50x50px. Note that there is no default avatar image shipped with this extension. The default is defined in extension.json and links to an external image on shoutwiki.com server, an ad-driven wiki farm. You may prefer to set this parameter to point to a local file.
• $wgCommentsInRecentChanges — by default, this variable is set to false. Set it to true to display comments log entries in Special:RecentChanges, too, in addition to the comments log at Special:Log/comments.
• $wgCommentsSortDescending — by default, this variable is set to false. Set it to true to sort comments by date descending, with the new comment box and most recent comments at the top.
• $wgCommentsAbuseFilterGroup — This is the custom group name for AbuseFilter for when the AbuseFilter extension is enabled. It ensures that AbuseFilter only pulls the filters related to Comments. If you want AbuseFilter to pull all the filters, enter 'default' here. The default value for this is 'comment', which ensures that AbuseFilter will only look for filters specifically written to target comments.

Magic words/Parser functions

Comments includes two magic words and a parser function:

• {{NUMBEROFCOMMENTS}} gives the entire number of comments on the wiki.
• {{NUMBEROFCOMMENTSPAGE}} gives number of comments on the current page.
• {{NUMBEROFCOMMENTSPAGE:<pagename>}} gives number of comments on the given page.

Hooks

Comments extension adds three hooks, Comment::add, Comment::delete and Comment::isSpam.

Hook name	When it is called	Parameters
Comment::add	After a comment has been added to the database, at the bottom of Comment::add function	$comment (instance of Comment class) $commentID $pageID
Comment::delete	After a comment has been deleted and the caches have been purged (function delete on class Comment)	&$comment (instance of Comment class) $commentID $pageID
Comment::isSpam	Called in Comment::isSpam before performing other spam checks.	&$text (user-supplied comment text to check against spam) &$retVal (boolean; function return value, i.e. does the supplied text contain spam (true) or not (false))

Anti-spam

Though (as of Q3/2023) Comments does not (yet) support ConfirmEdit, MediaWiki's de facto CAPTCHA extension, there are plenty of other anti-spam measures built in, including:

• restricting who can add comments and/or comments that contain hyperlinks (see the #User rights section above)
• support for $wgSpamRegex and $wgSummarySpamRegex
• possibility for extension developers to implement custom spam checks via the Comment::isSpam hook point (see the #Hooks section above)
• AbuseFilter interoperability — AbuseFilter can be made to check if the action variable's value is comment to write filters that apply only to comments made via the Comments extension; the new_wikitext variable contains the actual comment text, and the new_size variable is calculated on-demand based on the value of the new_wikitext variable. Refer to AbuseFilter's documentation for more details on how those variables and filters work.
  • The new configuration variable $wgCommentsAbuseFilterGroup can be set to 'default' to make existing AbuseFilter filters apply to comments as well. By default, it is set to 'comment', so only filters specifically designed to target comments will be executed against comments made via the Comments extension.

Internationalisierung

The Comments extension currently has (partial or full) support for 68 different languages, including English. Please visit translatewiki.net if you want to translate Comments or other extensions of the social tools family of extensions into your language or modify existing translations.
