How to display usernames with case sensitive in MediaWiki? - mediawiki

I have user named MyNiCkNaMe in my MediaWiki and in table user I see user_name=MyNiCkNaMe but on MediaWiki pages I see it as Mynickname is there any way to display it same as in db?

In LocalSettings.php include the line
$wgRestrictDisplayTitle = false;
Then on the user page use the magic word/parser function DISPLAYTITLE
{{DISPLAYTITLE:User:MyNiCkNaMe}}

Mediawiki: how to update page content from external script?

I would like to update the Main_Page of our wiki from a script run by cron.
Apart from the page content itself, in pagecontent.old_text, what else do I need to update?
If I only update the "old_text" field, the new content is not displayed. I get the previous content, presumably from a cache somewhere. In LocalSettings.php I have $wgMainCacheType = CACHE_NONE;. So I guess that I need to also update something else in the Mediawiki database?
(In case it matters, this is with Mediawiki 1.31.10 on Debian 10 with Apache and PostgreSQL)
Use maintenance/edit.php, the edit API, Pywikibot etc. Trying to do changes via direct DB manipulation is a rather bad idea.
Updating the timestamp in page.page_touched works to have the wiki show the new content.
This example is using a PostgreSQL database, so it might need some adjustments if used with the more common MySQL DB.
To update the text of a page identified by it's name, it is necessary to join the page, revision and pagecontent tables. This example updates a page named "Drafts":
UPDATE pagecontent
SET old_text = 'New page content'
FROM page, revision
WHERE page.page_title='Drafts'
AND pagecontent.old_id=revision.rev_text_id
AND page.page_latest=revision.rev_id;
And to update the page timestamp so that the wiki shows the new content:
UPDATE "page"
SET page_touched = now()
WHERE page_namespace = '0'
AND page_title = 'Drafts';
An alternative which avoids tinkering with the database directly, is to use an extension like External Data. There are examples here to embed a text file in a page, and here to embed the output of a database query.

MediaWiki - User Table

I'd like to include a table with all registered users on a page in my MediaWiki but the only user list I can find is the special page "Active users list".
Is it possible to include this (or a similar list with e.g. the entered real name) on a wiki page?
Thanks in advance for your help.
You can use the Special:ListUsers special page for this. It's a list of all users registered in your wiki.
You can include some special pages just like templates. So, to include the Special:ListUsers page on any wiki, you just need to paste the following wikitext code into the page where you want to show the user list:
{{Special:ListUsers}}
The limit for the list is 50 (iirc), so if you want to increase the length of the list, you can pass the limit parameter to the inclusion syntax:
{{Special:ListUsers|limit=100}}
However, I don't think that Special:ListUsers provides a way to show the real names of users, sorry.

How do I restrict a custom group to edit pages on mediawiki?

I am trying to restrict edit functionality for the group 'test' but unable to do so. Below are the changes I made so far:
$wgGroupPermissions['test']['read'] = true;
$wgGroupPermissions['test']['edit'] = false;
The problem is, that you create a new group and you want to revoke a permission for this group. $wgGroupPermissions isn't made to revoke permissions. Permissions granted via $wgGroupPermissions are cumulative, which means, that the permissions of all groups a user belongs to, reflects the permissions, the user has. If you set the edit permission of a group to false, and another group (e.g. user) has the edit permissions (set to true), the user (who belongs to both groups) will have the permission to edit. That's (maybe) a bit better explained on the Manual page (see the link above).
To achieve what you want, you need to:
Remove any other group with the edit permission from the user (that's not a good idea, if you have any other groups with special rights you get a really confusing and complex construct of permission management)
Use $wgRevokePermissions instead, see the example about how to revoke the edit permission for a group
Example to achieve what you want:
// inherit all rights from the user group
$wgGroupPermissions['test'] = $wgGroupPermissions['user'];
// revoke the edit permission for users in the group test
$wgRevokePermissions['test']['edit'] = true;
I hope that helps!
In MediaWiki, all users (including anonymous visitors) automatically belong to the group *, and all registered users (i.e. not anons) belong to the group user. By default, both of these automatic groups have the edit permission set to true, so every user can automatically edit pages.
To restrict editing to only certain users, you first need to remove those automatic edit rights by adding the following lines to your LocalSettings.php:
$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['user']['edit'] = false;
Now only users in groups that have the edit permission set to true can edit pages. There are no such groups by default, so to let anyone edit anything on your wiki, you'll have to add a few more lines to LocalSettings.php. For example, here's how to let admins (i.e. users in the group sysop) edit pages:
$wgGroupPermissions['sysop']['edit'] = true;
Alternatively, as already noted by Florian, you could use $wgRevokePermissions to remove editing rights from certain users. For example, here's how to allow all registered users, except those in the group blocked, to edit:
$wgGroupPermissions['*']['edit'] = false; // anons can't edit
$wgGroupPermissions['user']['edit'] = true; // normal users can edit
$wgRevokePermissions['blocked']['edit'] = true; // "blocked" users cannot
(Of course, the built-in user blocking feature in MediaWiki accomplishes this much better.)
Another option, if you wish to restrict editing only in certain namespaces, would be to use $wgNamespaceProtection, which lets you define a custom user right needed to edit pages in certain namespaces. For example, to allow only users in the custom group editor to edit pages in the main namespace, you could use:
$wgNamespaceProtection[NS_MAIN] = array( 'edit-main' );
$wgGroupPermissions['editor']['edit-main'] = true;

Hide toolbox for all users except admin and bureaucrat in MediaWiki

In skins/Vector.php I can hide toolbox from logged out user
by adding
global $wgUser;
then
case 'TOOLBOX':
if ( $wgUser->isLoggedIn() ) {
$this->renderPortal( 'tb', $this->getToolbox(), 'toolbox', 'SkinTemplateToolboxEnd' );
}
but User::isSysop() and similar are deprecated. It is recommended to use $user->isAllowed instead to specify a right, but how do I use this to specify the admin and bureaucrat group? Should I use some other function?
MediaWiki 1.22.2
PHP 5.3.6-13ubuntu3.10 (apache2handler)
MySQL 5.1.69-0ubuntu0.11.10.1-log
User::isAllowed() asks for a permission to do something, not for a user group (which leaves it up to the wiki admin to assign different rights to different user groups). In your case, you would want a new user permission, “see-toolbar”,or something like that, that you assign to e.g. the sysop user group in LocalSettings.php:
$wgGroupPermissions['sysop']['see-toolbar'] = true;
Your extension will also have to add the right to the list of available rights: $wgAvailableRights[] = 'see-toolbar';
Finally, you will ask for the permission like this:
if ( $user->isAllowed('see-toolbar') ) {
print toolbar here
}
More info on how to set user rights: https://www.mediawiki.org/wiki/Manual:User_rightser
Other extensions adding user rights: https://www.mediawiki.org/wiki/Category:Extensions_which_add_rights
Be aware that any user will still be able to bypass this restriction in a number of ways, e.g. by switching skin in their settings (or by appending ?useskin=skinname in the url). You probably want to make sure that sidebar caching is switched off too (it is off by default).

How do I create my own custom group in mediawiki?

I have been reading carefully through the MediaWiki documentation but I have not been able to find out how to create new groups.
When I look at Special:Userrights, I see only 3 groups :
Bots, Sysops, Bureaucrats
I would like to create my own custom groups, so I can use some extensions like the http://www.mediawiki.org/wiki/Extension:Group_Based_Access_Control.
Can someone tell me how it's done, or point me to some documentation?
You can add permissions for new groups to your LocalSettings.php file and they will automatically appear in the Special:UserRights page.
For example, I wanted to disallow editing by regular users but create a "Trusted" group that was allowed to edit. The following code creates a "Trusted" group that is equal to the "user" group, except that "Trusted" users can edit but "user" users cannot.
$wgGroupPermissions['Trusted'] = $wgGroupPermissions['user'];
$wgGroupPermissions['user' ]['edit'] = false;
$wgGroupPermissions['Trusted']['edit'] = true;
$wgGroupPermissions['sysop' ]['edit'] = true;
On the Special:UserRights page, I can now check the "Trusted" box to make users trusted.
You can alter the appearance of the group name by creating the following messages:
(For a group named ninja:)
MediaWiki:Group-ninja (content: Ninjas)
MediaWiki:Group-ninja-member (content: ninja)
MediaWiki:Grouppage-ninja (content: Project:Ninjas)
This will insure that the group will be referred to as "Ninjas" throughout the interface, and a member will be referred to as a "ninja", and overviews will link the groupname to Project:Ninjas.

Here you will find a List of Permissions. http://www.mediawiki.org/wiki/Manual:User_rights
I beleive I have found the answer, I just need to add the UserGroup and the permission to the wgGroupPermissions array in the LocalSettings.php file.
$wgGroupPermissions['TomatoUsers']['read'] = true;
$wgGroupPermissions['TomatoUsers']['edit'] = false;
I don't have the reputation to vote up the first answer (which can also be added to extension initialization files), but for when you get to adding users to your groups you may want to consider directly editing the database (ie. if you need to sync the wiki groups with external information). If you open the database "wikidb" the "PREFIX_user_groups"* table contains the mapping between user IDs (ug_user) and group names (ug_group). This table, combined with the "PREFIX_user"* table's name information (user_name) and ID information (user_id), give you all the information to add and remove large numbers of users from groups.
* Replace "PREFIX" with the database prefix you used for your wiki.
