Help:Managing user rights
Jump to navigation
Jump to search
User rights are specific access and ability permissions that can be assigned to customizable groups, which can then be assigned to (or removed from) users through the Special:Userrights interface. For example, the default bureaucrat group enables the use of the User rights interface.
This feature was introduced in MediaWiki 1.5; see setting user rights in MediaWiki on the Meta-wiki for earlier methods.
Managing groups
A default MediaWiki installation assigns certain rights to default groups (see below). You can change the default rights by declaring the $wgGroupPermissions array in LocalSettings.php with the syntax "$wgGroupPermissions[' group '][' right '] = boolean;". To change permissions for all groups, use "*" as the group. For example, to disable editing for all users, add "$wgGroupPermissions['*']['edit'] = false;".
In addition to the default groups, you can arbitrarily create new groups using the same array. For example:
$wgGroupPermissions['ninja']['bot'] = true; $wgGroupPermissions['ninja']['block'] = true; $wgGroupPermissions['ninja']['delete'] = true;
Rights and groups
The following user rights are available:
| Right | Description |
|---|---|
| Reading | |
| read | allows viewing pages not defined in $wgWhitelistRead. |
| Editing | |
| edit | allows editing unprotected pages. |
| createpage | allows the creation of new pages (requires the edit right). |
| createtalk | allows the creation of new talk pages (requires the edit right). |
| move | allows renaming page titles. |
| createaccount | allows the creation of new user accounts. |
| upload | allows the creation of new images and files. |

| Management | |
| delete | allows the deletion of edits and pages. |
| undelete | allows viewing and restoring deleted edits and pages. |
| deletedhistory | allows viewing deleted revisions, but not restoring. |
| protect | allows locking a page to prevent edits, and editing locked pages. |

| blockemail | allows preventing use of the Special:Emailuser interface when blocking. |
| userrights | allows the use of the user rights interface, which allows the assignment or removal of groups to any user. |
| rollback | allows one-click reversion of edits. |
| patrol | allows marking edits as legitimate ($wgUseRCPatrol must be true). |
| editinterface | allows editing the MediaWiki namespace, which contains interface messages. |

| import | allows user to import pages from another wiki. |
| importupload | allows user to import pages from XML files. |

| purge | allows purging a page without a confirmation step (URL parameter "&action=purge").
|
| minoredit | allows marking an edit as 'minor'. |
| nominornewtalk | blocks new message notification when making minor edits to user talk pages (requires minor edit right). |
| ipblock-exempt | makes user immune to blocks applied to his IP address. |
| proxyunbannable | makes user immune to the open proxy blocker, which is disabled by default ($wgBlockOpenProxies). |
| autopatrol | automatically marks all edits by the user as patrolled ($wgUseRCPatrol must be true). |
The following groups are available:
| Group | Description |

| * | all users (including anonymous). |
| user | registered accounts. |
| autoconfirmed | registered accounts at least as old as $wgAutoConfirmAge and having at least as many edits as $wgAutoConfirmCount. |
| emailconfirmed | registered accounts with confirmed email addresses. |
| bot | accounts with the bot right (intended for automated scripts). |
| sysop | users who by default can delete and restore pages, block and unblock users, et cetera. |
| bureaucrat | users who by default can change other users' rights. |
Default rights
The default rights are defined in DefaultSettings.php. MediaWiki 1.11alpha defines the following:
/** * Permission keys given to users in each group. * All users are implicitly in the '*' group including anonymous visitors; * logged-in users are all implicitly in the 'user' group. These will be * combined with the permissions of all groups that a given user is listed * in in the user_groups table. * * Functionality to make pages inaccessible has not been extensively tested * for security.

Those require * that a lock file be defined and creatable/removable by the web * server. */ # $wgGroupPermissions['developer']['siteadmin'] = true;
Examples
Anonymous users cannot view pages
This example will disable viewing of all pages not listed in $wgWhitelistRead, then re-enable for registered users only.
$wgGroupPermissions['*']['read'] = false; $wgGroupPermissions['user']['read'] = true;
