|Warning:||Flagged Revisions is very challenging to deploy and maintain, and can have seriously adverse effects on your wiki. Use with caution.|
The Flagged Revisions extension allows for Editor and Reviewer users to rate revisions of articles and set those revisions as the default revision to show upon normal page view. These revisions will remain the same even if included templates or images are changed. This allows for MediaWiki to act more like a Content Management System (CMS).
The extension can be retrieved directly from Git [?]:
- Browse code
- Some extensions have tags for stable releases.
- Browse tags
- Select the tag
- Click "snapshot"
- Each branch is associated with a past MediaWiki release. There is also a "master" branch containing the latest alpha version (might require an alpha version of MediaWiki).
- Browse branches
- Select a branch name
- Click "Continue"
Extract the snapshot and place it in the extensions/FlaggedRevs/ directory of your MediaWiki installation.
If you are familiar with git and have shell access to your server, you can also obtain the extension as follows:
cd extensions/ git clone
/var/www/mediawikidirectory. If you are working on a different family of operating systems, you will need to use commands and file paths appropriate to the operating system.
Follow these steps to install FlaggedRevs:
- Ensure that you are running MediaWiki version 1.17 or greater. If not, you will need to upgrade before you can install FlaggedRevs.
- Download FlaggedRevs. Choose a version of FlaggedRevs that matches the version of MediaWiki that you are using. For example: If you are running MediaWiki 1.17, download FlaggedRevs 1.17.
- Extract the downloaded file to the
extensions/FlaggedRevsdirectory of your MediaWiki installation. For example:
tar -xzf FlaggedRevs-MW1.17-r75373.tar.gz -C /var/www/mediawiki/extensions
- Ensure that image hashes are up-to-date by running the populateImageSha1.php maintenance script. For example:
- Make sure that the
chmod o+r extensions/FlaggedRevs/frontend/modules
- Enable collection of article review statistics.
- Disable on-demand statistic generation. Set
$wgFlaggedRevsStatsAge = false;in LocalSettings.php. This will prevent statistics from being generated when articles are accessed (which can lead to poor performance when many articles without current statistics are accessed concurrently).
- Set up scheduled statistics generation. Create a cron job to run
extensions/FlaggedRevs/maintenance/updateStats.phpat a regular interval. Run
time php updateStats.phpto see how long the script takes to run and set your cron jobs interval appropriately. For example, to create a cron job that runs
echo "@hourly php /var/www/mediawiki/extensions/FlaggedRevs/maintenance/updateStats.php" | crontab -u www-data -
Warning: This will delete all existing cron jobs for the user.
- Disable on-demand statistic generation. Set
- Enable FlaggedRevs by adding the following line to LocalSettings.php:
- Update MediaWiki's database schemas by running
php maintenance/update.php. This must be done after the above step is saved or you will receive a database error when accessing any page.
- Promote users to be reviewers. After FlaggedRevs is first installed, no user can see the reviewer's widget. To fix this, login as a wiki bureaucrat and go to Special:UserRights, then grant review rights to one or more users. Reviewers will see the reviewer's widget on the bottom of an editable page.
- If the hash table is up-to-date, images can be referenced by using their hashes rather than by a name/timestamp pair. In the future, image moves may be supported by MediaWiki, which will break references that used name/timestamp pairs.

User rights and user groups
By default, nobody can review anything, so the first step is to set up user rights.
|User groups||User rights|
FlaggedRevs creates the following new user rights:
review– user can review revisions
validate– user can review revisions and can set all tags to all levels
autoreview– any new revisions made by the user are automatically marked as sighted
autoreviewrestore– autoreview of the rollbacks made by the user.
unreviewedpages– user can view Special:UnreviewedPages
stablesettings– user can changes the settings of stable revisions of any page
movestable– user can move pages with stable revisions
FlaggedRevs creates the following new user groups:
autoreview, review, unreviewedpages, plus the standard MediaWiki user rights
autoreview, review, unreviewedpages, validate, plus the standard MediaWiki user rights
How to assign user rights
User rights can be assigned in two ways:
- Assigning rights to user groups
Assign these user rights to existing user groups in
$wgGroupPermissions['sysop']['review'] = true; //allow administrators to review revisions
- Assigning rights to specific users
Manually add user accounts to the appropriate groups via Special:UserRights.
- By default:
- Bureaucrats can add/remove Reviewers
- Administrators can add/remove both Autoreviewers and Editors.
FlaggedRevs.php comes with a number of configurable variables. These should be configured in LocalSettings.php.
$wgFlaggedRevsNamespaces– Sets what namespaces may be subject to the review process. This is an array of integers. Look at the beginning of includes/Defines.php to see what integer the default namespaces map to and use the defined constants for readability.
$wgFlaggedRevsTags– Sets the tags and their three settings: 'levels', 'quality', and 'pristine'
$wgFlaggedRevsTagsis an associative array with keys corresponding to each tag name and values that are arrays of the three settings 'levels', 'quality', and 'pristine':
- 'levels' controls the number of review levels,
- 'quality' decides what level the tag must be for a revision to be 'quality'
- 'pristine' decides what level the tag must be for a revision to be 'pristine'
- Each tag can be labeled editing the page MediaWiki:revreview-<tag-name>.
- Each tag level can be labeled editing the page MediaWiki:revreview-<tag-name>-<level-number>.
- Suppose one wants to have "accuracy", "depth", and "tone" tags, with 3 levels each.
- The admins also want revisions with at least "accuracy" and "depth" of the 2nd levels to count as "quality". The following settings will do that:
$wgFlaggedRevsTags = [ 'accuracy' => [ 'levels' => 3, 'quality' => 2, 'pristine' => 4 ], 'depth' => [ 'levels' => 3, 'quality' => 2, 'pristine' => 4 ], 'tone' => [ 'levels' => 3, 'quality' => 1, 'pristine' => 4 ], ];
- By default, the tags are labeled as they are set in the $wgFlaggedRevsTags array. In this example this means the tags appear exactly as 'accuracy', 'depth' and 'tone'.
- To show tags for example as their capitalized name, the admins have to edit these pages with the shown content:
tag labeling page content accuracy MediaWiki:revreview-accuracy Accuracy depth MediaWiki:revreview-depth Depth tone MediaWiki:revreview-tone Tone
- To label the tag levels, the admins have to create these pages with the shown content:
tag level labeling page content accuracy 0 MediaWiki:revreview-accuracy-0 Inadequate 1 MediaWiki:revreview-accuracy-1 Spot checked 2 MediaWiki:revreview-accuracy-2 Accurate depth 0 MediaWiki:revreview-depth-0 Inadequate 1 MediaWiki:revreview-depth-1 Basic 2 MediaWiki:revreview-depth-2 Moderate tone 0 MediaWiki:revreview-tone-0 Weak 1 MediaWiki:revreview-tone-1 Good 2 MediaWiki:revreview-tone-2 Excellent
- The resulting setup will be:
tag names level names Accuracy Inadequate Spot checked Accurate Depth Inadequate Basic Moderate Tone Weak Good Excellent
$wgFlaggedRevsOverride– Whether the stable version is the default content for pages.
- Individual pages can be configured to have the stable or draft version as the default content by administrators.
$wgFlaggedRevsTagsRestrictions– An array with keys corresponding to each flag type, and values that are arrays of rights and how high users with it can rate the flags (integral tag level).
$wgFlaggedRevsTagsRestrictions = [ 'accuracy' => [ 'review' => 1 ], 'depth' => [ 'review' => 2 ], 'style' => [ 'review' => 3 ], ];
$wgFlaggedRevsWhitelist– Array of string titles. These titles are pages that are exempt from FlaggedRevs. They are unreviewable and have no flagging UI. Replace ' ' with '_' in titles (e.g. "Main page" -> "Main_page").
$wgSimpleFlaggedRevsUI– When enabled, a simpler, icon based UI is used. Does not affect the tags shown in edit mode.
$wgFlaggedRevsLowProfile– This setting hides the review status box/bar for pages that are reviewed in their latest version. Explanatory text is also removed from some places.
$wgFlaggedRevsExceptions– Makes users in these groups see the current/draft revision by default.
$wgFlaggedRevsAutoReview– If enabled, every edit by a user with 'autoreview' rights is automatically reviewed upon save. There is no need to hit the "submit review" button. This feature requires that the previous revision was also reviewed; otherwise, auto-review will not occur.
wgFlaggedRevsAutoReviewis enabled, this settings controls how high each tag can be auto-reviewed. If allowed, tags will be auto-reviewed to the same level the previous revision tags were. This is an associative array; each key is a tag and each value is a tag level.
$wgFlaggedRevsTagsAuto = [ 'accuracy' => 1, 'depth' => 1, 'style' => 1 ];
- Changes in templates and images are auto-reviewed (per-page). This could possibly cause bad versions to be reviewed. Users should be encouraged to use preview or review the page after saving. You may want to set
[ 'editor' ]or
[ 'autoconfirmed' ]
Automatic user promotion
$wgFlaggedRevsAutopromote– An array with keys for days, edits, time spacing, benchmarks, emailconfirmed, recent content page edits, total content edits, content pages edited, edit summaries used, IP uniqueness, and userpage existence as keys. The values correspond to how many days/edits are needed for a user account to be autopromoted to Editor status and whether they must be emailconfirmed and have a user page do so. The user must have at least X edits that are Y or more days apart, where X is the number of benchmarks and Y is the time spacing. Set this variable to false to disable this entirely.
- If a user has their Editor rights removed, they will not automatically be re-granted (the editor status log is checked for revocations).
- Some of these counts are not retroactive, so you may notice a delay in promotions.
- For $wgFlaggedRevsAutopromote, one might have:
$wgFlaggedRevsAutopromote['days'] = 60; # days since registration $wgFlaggedRevsAutopromote['edits'] = 150; # total edit count $wgFlaggedRevsAutopromote['excludeDeleted'] = true; # exclude deleted edits from 'edits' count above? $wgFlaggedRevsAutopromote['spacing'] = 3; # spacing of edit intervals $wgFlaggedRevsAutopromote['benchmarks'] = 15; # how many edit intervals are needed? $wgFlaggedRevsAutopromote['recentContentEdits'] = 10; # $wgContentNamespaces edits in recent changes $wgFlaggedRevsAutopromote['totalContentEdits'] = 30; # $wgContentNamespaces edits $wgFlaggedRevsAutopromote['uniqueContentPages'] = 10; # $wgContentNamespaces unique pages edited $wgFlaggedRevsAutopromote['editComments'] = 5; # how many edit comments used? $wgFlaggedRevsAutopromote['email'] = true; # user must be emailconfirmed? $wgFlaggedRevsAutopromote['userpageBytes'] = 0; # if userpage is needed, what is the min size?
See FlaggedRevs.php for a complete list of configuration options (with some explanatory comments). Be sure to change only localsettings.php to set configuration options rather than editing this file.
To have a wiki where non-users can only see the stable version of articles, see Extension:FlaggedRevs/Restricting unapproved revisions.
- See also: Help:FlaggedRevs
Users with some level of review status will have a small rating form on page view (at the bottom of the page) and diffs (at the top of the page) that lets them review revisions. Each tag must at least meet the minimal level of approval. Users should look at the whole page, included templates and images, before reviewing. The (diff to stable) link is very useful for speeding up this process.
Users cannot review a page which they cannot edit. They cannot lower the level of a revision from a level they cannot set. Blocked users cannot do anything.
At Special:StableVersions, you can list out all of the reviewed revisions for a certain page or view reviewed revisions.
At Special:UnreviewedPages, there is a list of pages that have not yet been reviewed, for Editors only. A namespace must be selected and an optional category filter is also present.
At Special:OldReviewedPages, there is a list of pages that have been reviewed, but have edits pending. This is for Editors only. An optional category filter is also present.
Pages that cannot be reviewed can still be patrolled for anti-vandalism purposes by Editors to see what has been checked already.
A list of reviewed pages at the main review levels can be found at Special:ReviewedPages.
All relevant actions are permanently logged, so everything can be tracked and overseen properly.
- A log of promotion/demotion of editors and the reasons is kept at Special:Log/userrights.
- A log of the approval/unapproval of revisions is kept at Special:Log/review.
- A log of changes to the stable versioning configuration to pages is logged at Special:Log/stable.
Also, a new page, Special:QualityOversight shows only flaggings log entries related to quality revisions. This is useful if the main log is too flooded with page "sightings".
$wgUseRCPatrolis enabled with the extension. Patrolling of reviewable pages is disabled, but flagged revisions are marked as patrolled in Recent Changes. This will mean that the only way to patrol a reviewable revision is to flag it. Non-reviewable pages still behave as normal (depending on site patrol settings).
- Sysops can change whether quality revision have precedence or whether the stable version is shown by default for specific pages. To disable this, add
$wgGroupPermissions['sysop']['stablesettings'] = false;to LocalSettings.php.
- Page links, category, image, template, language, and external links are still based on the current version of pages.
- Users cannot move pages they cannot review. This is deliberate; see task T15994. To work around this, add
$wgGroupPermissions['autoconfirmed']['movestable'] = true;to LocalSettings.php
- You can demote Editors either temporarily by blocking them or permanently via Special:UserRights. An extra demotion log item will appear for tracking purposes.
FlaggedRevs adds API modules for reviewing revisions and configuring "stabilization" of pages, a module for retrieving flag configuration, and three list modules corresponding to the special pages for reviewed pages, unreviewed pages and "old" reviewed pages.
Some more API documentation is at Extension:FlaggedRevs/API.
action = review
Reviews a page.
revid: The revision ID for which to set the flags
token: A csrf token retrieved through action=query&meta=tokens
comment: Comment for the review (optional)
flag_accuracy: Set the flag named "accuracy" to the specified value; (replace "accuracy" with the flag name to set another flag)
Review revision 12345
action = stabilize
Changes page stabilization settings.
title: Title of page to be stabilized
reason: Reason for stabilization
expiry: (Deprecated?) Stabilization expiry. Default: infinite
review: Whether to auto-review the page
watch: Whether to watch the page
token: An edit token retrieved through action=query&meta=tokens
- For protection-like configurations (
protectlevel: The right users must have in order for their edits to not require review.
- Otherwise (
default: Default revision to show (latest | stable)
precedence: Which stable revision should be shown (pristine | quality | latest). Default: quality
autoreview: Restriction level for the 'autoreview' right (sysop | none). Default: none
Configure the page "Foo" such that only quality revisions are shown by default
action = flagconfig
Shows information about review flag configuration.
The following parameters are returned for each tag:
name: the name of the flag
levels: the number of possible levels the flag has (not counting the "unreviewed" level)
tier2: level the flag must be for the revision to be considered "quality"
tier3: level the flag must be for the revision to be considered "pristine"
The displayed name for each flag and the different level names for each flag are MediaWiki messages, so can be set and retrieved through the appropriate page; for example the name for the first level of the "accuracy" flag is located at MediaWiki:revreview-accuracy-1.
Retrieve flag configuration

- Transclusions across wikis are not stabilized
- External images (aside from Commons) are not stabilized
- Metatemplates that conditionally include other templates may have the condition change between the time a reviewer loaded a page and when they reviewed it. Therefore, there would be no pointers to the revision id for this different template to load from, making it blue linked. You will be notified if this happens during review.
- Remove the include line from
- Drop the tables in
- Drop the columns
page_ext_stable, and the index
pagetable (if they exist; only older versions of FlaggedRevs used these)
