Extension:Comments

The Comments extension adds the 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  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.

Usage

 * — basic comment form, sufficient for most things
 * — only allows the users Derfel, Jack Phoenix and Misza to submit comments
 * — 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, 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:

If the  argument is passed to the parser hook (like this: ), the parser hook will not use memcached and will just 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.

User rights
This extension adds three new user rights:
 * (which allows posting comments)
 * (which allows posting external links in comments)
 * (which allows deleting user-posted comments), e.g.

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

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

By default only users in the  group can delete comments.

User points

 * $wgUserStatsPointValues['comment_plus'] &mdash; amount of points to give out when another user gives "thumbs up" to your comment.
 * $wgUserStatsPointValues['comment_ignored'] &mdash; amount of points to give out when another user adds your comments to their ignore list (Special:CommentIgnoreList).

Parameters

 * $wgCommentsDefaultAvatar &mdash; path to an image which will be displayed instead of an avatar if social tools (SocialProfile extension) aren't installed. 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 &mdash; by default, this variable is set to . Set it to   to display comments log entries in Special:RecentChanges, too, in addition to the comments log at Special:Log/comments.
 * $wgCommentsSortDescending &mdash; by default, this variable is set to . Set it to   to sort comments by date descending, with the new comment box and most recent comments at the top.

Magic words/Parser functions
Comments includes 2 magic words and a parser function:


 * gives the entire number of comments on the wiki.
 * gives number of comments on the current page.
 * gives number of comments on the given page.

Hooks

TODO list

 * 1) HTML output is not valid XHTML - would be nice if it were but we can live without that
 * 2) Would be nice if there was a special page that gives a overview of all uses of the Comments extension on all pages (for an adminstrator to be able to moderate easier)
