Manual:User rights

From Linux Web Expert

User rights are permissions (like the ability to edit pages or to block users) that can be assigned to different user groups. MediaWiki ships with a default set of user rights and user groups, but these can be customized. This page explains the default rights and groups and how to customize them.

For information about how to add and remove individual wiki users from groups, see Help:User rights and groups and Manual:Setting user groups in MediaWiki .

Changing group permissions

A default MediaWiki installation assigns certain rights to default groups (see below). You can change the default rights by editing the $wgGroupPermissions array in LocalSettings.php with the syntax. 

$wgGroupPermissions['group']['right'] = true /* or false */;
In a default installation $wgGroupPermissions will be set in includes/DefaultSettings.php, but it is not present in LocalSettings.php. You will then need to add it in that file.

If a member has multiple groups, they get all the permissions from each of the groups they are in. All users, including anonymous users, are in the '*' group; all registered users are in the 'user' group. In addition to the default groups, you can arbitrarily create new groups using the same array.

Examples

This example will disable viewing of all pages not listed in $wgWhitelistRead , then re-enable for registered users only: 

$wgGroupPermissions['*']['read'] = false;
# The following line is not actually necessary, since it's in the defaults. Setting '*' to false doesn't disable rights for groups that have the right separately set to true!
$wgGroupPermissions['user']['read'] = true;

This example will disable editing of all pages, then re-enable for users with confirmed email addresses only: 

# Disable for everyone.
$wgGroupPermissions['*']['edit'] = false;
# Disable for users, too: by default 'user' is allowed to edit, even if '*' is not.
$wgGroupPermissions['user']['edit'] = false;
# Make it so users with confirmed email addresses are in the group.
$wgAutopromote['emailconfirmed'] = APCOND_EMAILCONFIRMED;
# Hide group from user list.
$wgImplicitGroups[] = 'emailconfirmed';
# Finally, set it to true for the desired group.
$wgGroupPermissions['emailconfirmed']['edit'] = true;

Creating a new group and assigning permissions to it

You can create new user groups by defining permissions for the according group name in $wgGroupPermissions[ 'group-name' ] where group-name is the actual name of the group.

Additionally to assigning permissions, you should create these three wiki pages with fitting content:

  • MediaWiki:Group-<group-name> (content: Name of the group)
  • MediaWiki:Group-<group-name>-member (content: Name of a member of the group)
  • MediaWiki:Grouppage-<group-name> (content: Name of the group page)

By default, bureaucrats can add users to, or remove them from, any group. However, if you are using Manual:$wgAddGroups and Manual:$wgRemoveGroups , you may need to customize those instead.

Examples

This example will create an arbitrary "projectmember" group that can block users and delete pages, and whose edits are hidden by default in the recent changes log: 

$wgGroupPermissions['projectmember']['bot'] = true;
$wgGroupPermissions['projectmember']['block'] = true;
$wgGroupPermissions['projectmember']['delete'] = true;
The group name cannot contain spaces, so use 'random-group' or 'random_group' instead of 'random group'. Moreover it is recommended to only use lowercase letters to create a group.

In this example, you would probably also want to create these pages:

  • MediaWiki:Group-projectmember (content: Project members)
  • MediaWiki:Group-projectmember-member (content: Project member)
  • MediaWiki:Grouppage-projectmember (content: Project:Project Members)

This will ensure that the group will be referred to as "Project members" throughout the interface, and a member will be referred to as a "Project member", and overviews will link the group name to Project:Project members.

This example disables write access (page editing and creation) by default, creates a group named "writer", and grants it write access. Users can be manually added to this group via Special:UserRights: 

$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['*']['createpage'] = false;
$wgGroupPermissions['user']['edit'] = false;
$wgGroupPermissions['user']['createpage'] = false;
$wgGroupPermissions['writer']['edit'] = true;
$wgGroupPermissions['writer']['createpage'] = true;

In this example, you would probably also want to create these pages:

  • MediaWiki:Group-writer (content: Writers)
  • MediaWiki:Group-writer-member (content: Writer)
  • MediaWiki:Grouppage-writer (content: Project:Write)

Removing predefined groups

MediaWiki out of the box comes with a number of predefined groups. Most of these groups can be removed by unsetting the according array keys, among them $wgGroupPermissions[ '<group-name>' ]. For details, see below.

Example

This example will eliminate the bureaucrat group entirely. It is necessary to ensure that all six of these variables are unset for any group that one wishes to remove from being listed at Special:ListGroupRights; however, merely unsetting $wgGroupPermissions will suffice to remove it from Special:UserRights. This code should be placed after any require_once lines that add extensions, such as Extension:AntiSpoof containing code that gives bureaucrats group permissions by default. 

unset( $wgGroupPermissions['bureaucrat'] );
unset( $wgRevokePermissions['bureaucrat'] );
unset( $wgAddGroups['bureaucrat'] );
unset( $wgRemoveGroups['bureaucrat'] );
unset( $wgGroupsAddToSelf['bureaucrat'] );
unset( $wgGroupsRemoveFromSelf['bureaucrat'] );

In some extensions (Flow, Semantic MediaWiki, etc.), rights are added during extension registration or in a registration function. In this case, it could be necessary to use a registration function in LocalSettings.php to remove some predefined user groups: 

$wgExtensionFunctions[] = function() use ( &$wgGroupPermissions ) {
    unset( $wgGroupPermissions['oversight'] );
    unset( $wgGroupPermissions['flow-bot'] );
};


Note on the group called "user"

With the above mechanism, you can remove the groups sysop, bureaucrat and bot, which - if used - can be assigned through the usual user permission system. However, it is currently impossible to remove the user group. This group is not assigned through the usual permission system. Instead, every logged-in user automatically is a member of that group. This is hardcoded in MediaWiki and currently cannot be changed easily.

writeapi Use of the write API - requires the edit right *, user, bot 1.13+
Although these permissions all control separate things, sometimes to perform certain actions you need multiple permissions. For example allowing people to edit but not read pages doesn't make sense, since in order to edit a page you must first be able to read it (Assuming no pages are allowlisted). Allowing uploads but not editing does not make sense, since in order to upload an image you must implicitly create an image description page, etc.

List of groups

The following groups are available in the latest version of MediaWiki. If you are using an older version then some of these may not be implemented.

Group Description Default rights Versions
* all users (including anonymous). createaccount, createpage, createtalk, edit, editmyoptions, editmyprivateinfo, editmywatchlist, read, viewmyprivateinfo, viewmywatchlist, writeapi 1.5+

bureaucrat users who by default can change other users' rights. noratelimit, userrights 1.5+
suppress deletelogentry, deleterevision, hideuser, suppressionlog, suppressrevision, viewsuppressed

From MW 1.12, you can create your own groups into which users are automatically promoted (as with autoconfirmed and emailconfirmed) using $wgAutopromote . You can even create any custom group by just assigning rights to them.

Default rights

The default rights are defined in MainConfigSchema.php .

Adding new rights

Information for coders only follows.

If you're adding a new right in core, for instance to control a new special page, you are required to add it to the list of available rights in PermissionManager.php , $coreRights (example). If you're doing so in an extension , you instead need to use $wgAvailableRights .

You probably also want to assign it to some user group by editing $wgGroupPermissions described above.

If you want this right to be accessible to external applications by OAuth or by bot passwords, then you will need to add it to a grant by editing $wgGrantPermissions . 

// create projectmember-powers right
$wgAvailableRights[] = 'projectmember-powers';

// add projectmember-powers to the projectmember-group
$wgGroupPermissions['projectmember']['projectmember-powers'] = true;

// add projectmember-powers to the 'basic' grant so we can use our projectmember powers over an API request
$wgGrantPermissions['basic']['projectmember-powers'] = true;

You also need to add right-[name] and action-[name] interface messages to /languages/i18n/en.json (with documentation in qqq.json). The right-* messages can be seen on Special:ListGroupRights and the action-* messages are used in a sentence like "You do not have permission to ...".
