Asas

Apakah perbezaan di antara MediaWiki, Wikimedia, Wikipedia dan wiki?

Sila lihat Perbezaan di antara Wikipedia, Wikimedia, MediaWiki, dan wiki untuk jawapan terperinci.

Saya ingin menggunakan Mediawiki untuk (apa sahaja). Adakah ini dibenarkan?

MediaWiki ialah aplikasi bebas: ini bermakna anda boleh menggunakannya untuk sebarang tujuan tanpa halangan undang-undang. Tambahan pula, syarat lesen hanya dikenakan kepada aplikasi itu sendiri sahaja. Ini bermakna walaupun banyak wiki melesenkan kandungan mereka di bawah lesen yang dibenarkan, anda tidak diwajibkan untuk melesenkan kandungan yang dihantar kepada wiki anda dalam apa jua sekalipun. Sudah tentu, sebagai projek yang yang ditubuhkan untuk menyokong laman seperti Wikipedia, kami menggalakkan anda untuk melesenkan teks yang anda tulis di bawah lesen bebas, namun, secara ringkasnya, anda tidak perlu lakukannya.

Jika anda ingin melakukan perubahan atau memperbaiki aplikasi ini sendiri, secara umumnya, dibenarkan, namun terdapat beberapa sekatan dan anda harus merujuk kepada teks penuh GNU GPL versi 2 untuk butiran lanjut. Oleh kerana penggunaan MediaWiki diberikan secara percuma, tiada waranti disediakan, sehingga setakat yang dibenarkan oleh undang-undang berkaitan.

Bagaimana cara saya mencipta sebuah wiki?

Mencipta wiki bermakna memasang aplikasi MediaWiki ke dalam pelayan dan mempunyai akses untuk menguruskannya. Terdapat beberapa pilihan, bergantung kepada tahap kepakaran anda:

  • Untuk mencipta wiki dalam pelayan anda sendiri, sila ikuti Panduan pemasangan.
  • Sesetengah pengehosan menawarkan pemasangan dengan satu klik, atau membenarkan penciptaan wiki atas permintaan. Lihat Perkhidmatan pengehosan untuk pelbagai pilihan.

Laman ini (MediaWiki.org) atau laman Yayasan Wikimedia tidak membenarkan seseorang untuk mencipta wiki.

Pemasangan dan konfigurasi

Di mana saya boleh memuat turun MediaWiki?

Muat turun MediaWiki keluaran stabil yang terkini. Fail disediakan dalam bentuk arkib .tar.gz. MediaWiki juga boleh didapati secara terus menerusi repositori Git kami.

Bagaimana cara memasang MediaWiki?

Memasang MediaWiki memerlukan masa antara 10 hingga 30 minit, termasuklah muat naik/penyalinan fail, dan menjalankan skrip pemasangan bagi melakukan konfigurasi terhadap aplikasi. Lihat Manual:Installation guide , di mana anda juga akan melihat keperluan sistem minima.

Bagaimana cara memasang MediaWiki dengan menggunakan pakej?

Kebanyakkan edaran Linux menawarkan MediaWiki dalam format pakej bagi edaran tertentu. Pasukan pembangunan MediaWiki mencadangkan anda untuk merujuk kepada edaran Linux anda bagi bantuan berkaitan pemasangan, konfigurasi atau menggunakannya. Komuniti individu atau syarikat yang mengendalikan pakej tersebut seharusnya menyediakan panduan pemasangan.

Ambil perhatian bahawa edaran dari pihak ketiga mungkin mengandungi versi terdahulu, jadi sila teliti akan maklumat kesesuaian untuk sokongan arah dan sambungan.

Bolehkah saya memasang lebih daripada satu wiki ke dalam pelayan menggunakan MediaWiki?

Pemasangan lebih daripada satu wiki dalam pelayan adalah tidak mustahil dengan syarat:

  • Anda memasang beberapa aplikasi MediaWiki tambahan (contoh aplikasi longgokkan seperti tindanan Bitnami MediaWiki); dalam direktori yang berlainan – satu bagi setiap wiki.

Atau

  • Anda menggunakan pangkalan data yang berbeza untuk setiap wiki

Atau

  • Anda menggunakan awalan berbeza bagi pangkalan data untuk setiap wiki (untuk Postgres, anda boleh melakukan hal yang serupa dengan menggunakan schema dan pengguna berbeza). If you want to use the same LocalSettings.php file for both, you must ensure $wgServer is dynamically set to the correct value.

Untuk maklumat lanjut mengenai dua pilihan terakhir itu, lihat $wgDBname dan $wgDBprefix .

Untuk maklumat lanjut mengenai penetapan keluarga wiki (ladang wiki), lihat Manual:Wiki family .

Bagaimana saya ingin memasangkan wiki sedia ada, seperti Wikipedia atau Wikikamus?

Kaedah utama (tak semestinya paling mudah) adalah dengan melakukan import. Lihat Mengimport wiki, di bawah.

(Kaedah bukan MediaWiki, seperti Xowa dan Kiwix boleh didapati di w:Wikipedia:Database download). (dalam bahasa Inggeris)

Adakah MediaWiki memerlukan akses shell?

Akses shell (SSH) tidak diperlukan untuk pemasangan MediaWiki, namun ianya sangat disarankan. Tanpa akses shell, mungkin sukar bagi anda untuk melakukan sandaran terhadap wiki anda, atau menaik taraf kepada versi baharu. Beberapa tugas penyelenggaraan mungkin tidak dapat dilakukan tanpa akses shell. Kebanyakkan sambungan utama berfungsi dengan lebih baik dengan akses shell.

Bagaimana saya ingin memasang sambungan?

Lihat Manual:Extensions untuk maklumat mengenai pemasangan dan membangunkan sambungan. Lihat Kategori:Sambungan untuk mencari sambungan sedia ada.

Bagaimana saya menambah kosa nama tambahan?

Lihat Mencipta kosa nama buatan.

Bagaimana saya mengaktifkan fungsi muat naik?

Muat naik fail merupakan fungsi yang selalu digunakan dalam MediaWiki, namun ianya dilumpuhkan secara asal dalam kesemua versi keluaran terkini. Untuk mengaktifkannya, pertama lakukan muat naik direktori (images asalnya) boleh tulis oleh pelayan web (chmod -R 777 ./images atau benarkan pengguna Apache untuk menulis di dalamnya, dan lain-lain) kemudian tetapkan $wgEnableUploads kepada true dalam fail LocalSettings.php. Jika anda menerima mesej ralat "failed to mkdir" semasa anda cuba untuk melakukan muat naik, ini berkemungkinan terdapat masalah berkaitan kawalan keizinan.

Lihat juga: Manual:Configuring file uploads

How do I allow uploading of additional formats?

MediaWiki requires that allowed file upload formats are specified using the $wgFileExtensions configuration directive. Usually this directive is situated in LocalSettings.php in the root of your MediaWiki installation.

For example, to extend uploading to PDF files, add the following to LocalSettings.php: 

$wgFileExtensions[] = 'pdf';

To extend uploading to more than one type of file, use the following syntax 

$wgFileExtensions = array_merge( $wgFileExtensions, [ 'pdf', 'txt', 'mp3' ] );
See also: Manual:Configuring file uploads

How do I enable embedded math formulas?

MediaWiki allows embedded math formulas. See Extension:Math for complete setup instructions.

How do I set the timezone for my MediaWiki?

See Manual:Timezone

How do I purge a cached page?

To purge a cached page, such as when making changes to the navigation bar, add &action=purge to the end of the page's dynamic URL.

E.g. https://www.mediawiki.org/w/index.php?title=Main_Page&action=purge

Or ?action=purge to the end of the page's short form URL:

E.g. https://www.mediawiki.org/wiki/Main_Page?action=purge

See also: Manual:Purge , Manual:Parameters to index.php

How do I completely disable caching?

Add in your LocalSettings.php file the following lines:

$wgParserCacheType = CACHE_NONE; $wgCachePages = false;

"File is corrupt or has an invalid extension"

Some users have reported that after adding a file format to the allowed extensions list, an error is encountered. The text of the error is similar to the following:

The file is corrupt or has an incorrect extension. Please check the file and upload again.

As a possible solution, set the value of $wgMimeDetectorCommand . Under Unix or Linux, this would be 

$wgMimeDetectorCommand = "file --brief --mime";
See also: Manual:MIME type detection

Initial user was not created by installer or it is not an administrator

Sometimes, the installer fails to create the default user, or the user table is lost for some reason. There are a couple of options for solving this:

maintenance/createAndPromote.php

Append --bureaucrat to command line if you want that user to become a bureaucrat, in addition to becoming an administrator.

This will create a new user and promote them to an administrator. For help, run the script with the parameter --help.

Alter the database

  • Execute the following SQL statement against the database:
    • INSERT INTO user_groups ( ug_user, ug_group ) VALUES ( <id>, 'bureaucrat' ), ( <id>, 'sysop' );
<id> above should be replaced with the appropriate user ID which you can see on the user's preference page.
Note: if $wgDBprefix is defined in LocalSettings.php, prepend its value to the table name. For example, if $wgDBprefix is "XYZ", then the table name to use is XYZuser_groups

Temporarily let everyone assign rights to promote your initial user

Warning Warning: You should not let outsiders access your wiki while you do this, if you use this method. This method may leave your wiki temporarily vulnerable to attack while you do the procedure.

This method essentially involves letting all users temporarily modify user permissions in order to promote one user

Be logged in using that account.

  • Add the following line to the bottom of LocalSettings.php
    • $wgGroupPermissions['user']['userrights'] = true;
  • Go to special:userrights and add the user you just created to the Administrator and Bureaucrat groups.
  • Remove the $wgGroupPermissions['user']['userrights'] = true; line from your LocalSettings.php.

This step is very important, as until you remove it anyone can alter permissions, which is bad.

How do I reset a user's MediaWiki password?

See Manual:Resetting passwords
See Manual:Interwiki

How do I make my base URLs shorter?

(i.e. /wiki/Article_Name as opposed to /w/index.php?title=Article_Name)

See Manual:Short URL

How do I organize pages into subdirectories like /wiki/subdir/PageName?

See Manual:$wgNamespacesWithSubpages dan Help:Subpages

Is downloading and using all of MediaWiki.org free?

Yes, it is free in the sense of Free software. See Project:Copyrights for licensing issues regarding the written content of this site.

How do I administrate/manage user rights?

See Manual:User rights for general information. See Manual:Preventing access for methods and strategies for restricting access.

How do I stop anonymous users from editing any page?

The recommended method is by changing the value of the $wgGroupPermissions configuration option. Edit LocalSettings.php and add the line: 

$wgGroupPermissions['*']['edit'] = false;

If you use Extension:AbuseFilter , any admin can also disable IP editing temporarily as needed.

See also: Preventing access , Manual:User rights

How do I stop anonymous users from reading any page?

  • Add this to the bottom of LocalSettings.php:
$wgGroupPermissions['*']['read'] = false;

See also Manual:$wgWhitelistRead . See Manual:Preventing access#Restrict viewing of all pages for more information.

How do I restrict account creation?

  • Add this to the bottom of LocalSettings.php:
$wgGroupPermissions['*']['createaccount'] = false;

See Manual:Preventing access#Restrict account creation for more information.

How do I require an email address be specified at registration?

See Manual:$wgEmailConfirmToEdit

How do I put MediaWiki into Read Only mode?

MediaWiki version:
≥ 1.5
See Manual:$wgReadOnly

How do I change default user preferences?

MediaWiki version:
≥ 1.4

The MediaWiki default user preferences are in MainConfigSchema.php Don't edit that file, just use it for reference.

Say if you want to hide minor edits in recent changes by default. MainConfigSchema.php says: 

public const DefaultUserOptions = [
        ...
	'hideminor' => 0,
        ...
]

To change the preference, put this in your LocalSettings.php: 

$wgDefaultUserOptions["hideminor"] = 1;

To change the default namespaces to be searched, in any version of MediaWiki, set $wgNamespacesToBeSearchedDefault in LocalSettings.php to an array mapping namespace indexes to boolean values. For example, to search the main namespace and the category namespace, use: 

$wgNamespacesToBeSearchedDefault = [
    NS_MAIN => true,
    NS_CATEGORY => true,
];

In some cases, after you change a default user preference, you may also want to change the user preferences of all existing user accounts.

If so, use the userOptions.php script in the maintenance directory. Use the --dry option for the first run, assess the impact and go from there. (--dry does not write the database.) 

php userOptions.php --dry --nowarn hideminor --old 0 --new 1

Also, always backup your database before making these kinds of changes (you do not need to if you are just using --dry).

How can I make MediaWiki run faster?

See: Manual:Performance tuning

How do MediaWiki and GDPR go together?

See GDPR (General Data Protection Regulation) and MediaWiki software

Upgrading

See Manual:Naik taraf

Moving

Is it possible to move my wiki to a different machine?

Yes. It should be. In essence, you will be backing up your old installation and then "restoring" it onto the new machine. Finally, you will have to make additional modifications to update the wiki configuration so that everything points to the new location.

How do I move my wiki to a different server?

Follow the instructions at Manual:Moving a wiki .

Changing the interface

How do I change the logo?

Caution! Caution: Do not simply overwrite the default logo installed within MediaWiki (/resources/assets/wiki.png); this file will be overwritten when you upgrade the software.
A larger size can be used by modifying the site’s CSS, but MediaWiki will not resize a logo that is too large. Instead, only part of the image (specifically the upper left-hand corner) will be displayed, and if this corner is white, it may seem like the image is not displaying.
The recommended size for a square logo is 135 × 135px, though the logo doesn’t have to be square, especially if it includes text below an image.

The maximum logo size in the Vector skin is ~160 × 160px, while in MonoBook it’s ~155 × 155px.

The logo that appears in the top left of each page is determined by the $wgLogos configuration line in the LocalSettings.php file. MediaWiki installations prior to MediaWiki 1.35.0, used $wgLogo .

There are two ways to change the logo:

  1. Upload a picture to your wiki using the normal file uploading interface. This allows the logo to be replaced easily, so you may want to protect the page if you use this method.
    The resulting logo path will be 
    "{$wgUploadPath}/6/62/mylogo.png";
    .
  2. Upload path image to your server by other means (such as FTP).
    The resulting logo URL will be 
    $wgLogos = "{$wgScriptPath}/mylogo.jpg";
    .
    (In this example, the image is in the same folder as the LocalSettings.php file.)

Then, modify the $wgLogos array in LocalSettings.php. It should look something like: 

$wgLogos = [
	'1x' => "$wgResourceBasePath/resources/assets/change-your-logo.svg"
	'icon' => "$wgResourceBasePath/resources/assets/change-your-logo-icon.svg"
];

Replace the paths above with the appropriate new logo path.

If you only want to change the logo on specific pages, override #p-logo CSS's background-image property or use a third-party extension like Extension:LogoFunctions .

How do I edit the wiki's CSS?

You shouldn't edit the CSS files (such as common.css) directly, because it will make upgrading harder if you need to apply your customizations each time you upgrade the software. Instead you need to edit a wiki page called MediaWiki:Common.css if you want to apply your CSS changes for all skins, or a wiki page called MediaWiki:Vector.css if you want to apply the customizations only for the Vector skin.

The content of the MediaWiki:Common.css and MediaWiki:Vector.css pages always overrides the default CSS styles specified in the skin files.

How do I hide the left vertical navigation toolbar?

In other words, how do you make the main content div take up 100% of the display, hiding the logo, toolbox, navigation and search engine?

To hide it permanently, copy and paste the following into the MediaWiki:Common.css page: 

#column-content { margin: 0 0 .6em 0; }
#content { margin: 2.8em 0 0 0; }
#p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search { display:none; }
#p-cactions { left: .1em; }

To instead hide the toolbar when the user presses F11, enter this in your wiki's MediaWiki:Common.js: 

document.onkeydown = function( e ) {
	if( e == null ) e = event
	if( testKey( e, 122 ) ) { //F11
		appendCSS('#column-content {margin: 0 0 .6em 0;} #content {margin: 2.8em 0 0 0;} #p-logo, .generated-sidebar, #p-lang, #p-tb, #p-search {display:none;} #p-cactions {left: .1em;} #footer {display:none;}');
		return false;
	}
}

function testKey( e, intKeyCode ) {
	if( window.createPopup )
		return e.keyCode == intKeyCode
	else
		return e.which == intKeyCode
}


How do I hide the categories at the bottom of each page?

You can hide display of the categories on each page by modifying your MediaWiki:Common.css and adding: 

.catlinks { display: none; }

By default, clicking the site-logo takes you to the main site-page. If you want to change which internal site-page is the "main" site-page, edit MediaWiki:Mainpage.

To make the link of the site-logo link externally to any other arbitrary URL, you can use jQuery code within MediaWiki:Common.js: 

$("a.mw-wiki-logo").attr("href", "http://www.example.com");
$("a.mw-wiki-logo").attr("title", "Go to example.com website");

How do I change the icon in the browser's address line (favicon)?

  • Simply upload your favicon.ico to the root of your domain/subdomain, make sure file name is in lower case and its name is favicon.ico
  • Alternatively edit the $wgFavicon setting in LocalSettings.php and add

$wgFavicon = "$wgScriptPath/path/to/your/favicon.ico";

See Manual:$wgFavicon for more details.

Tip: The favicon image should be either 16 x 16 pixels or 32 x 32 pixels.

Rewrite Rule

If you are using a rewrite rule in .htaccess to remove "index.php" from the URL, you will also need to add an exception for .ico files. Simply add the following rule to your .htaccess: 

RewriteRule .*\.ico$ - [L]

This rule must appear before the index.php rule.

Case sensitivity

When uploading the favicon file, be sure the filename is in lowercase. (That is, "favicon.ico", not "Favicon.ico".) A lot of servers (e.g., those on UNIX-like operating systems) will not be able to find the file unless its name is in lowercase.

How do I customize the navigation bar?

The contents of the navigation bar which appears to the left of each page using the Vector or the Monobook skin are determined by the MediaWiki:Sidebar page there on your wiki. For information on customising these, please see Manual:Interface/Sidebar .

How do I put a text message (sitenotice) on every page?

Put a text in the MediaWiki:Sitenotice page. It will be displayed on top of every article page.

You can also add text to MediaWiki:Anonnotice to create a message that only displays for logged-out users. It is often a good idea to transclude the site notice on the anon notice to make sure that logged-out users still get the information on the site notice.

How do I change which page is the main page?

By default, MediaWiki looks for a page with the title Main Page and serves this as the default page. This can be changed by altering the contents of MediaWiki:Mainpage to point to a different title. If this does not change the 'Main Page' link included on the sidebar at install time, edit MediaWiki:Sidebar .

How do I change the Main Page title?

Simply click on the "Move" tab, and move the page to the desired page title.

Usually you also want to change which page is the configured as "main page".

How do I hide the main page title?

The displayed title of the main page can be changed using the MediaWiki messages MediaWiki:mainpage-title and MediaWiki:mainpage-title-loggedin (for logged-out and logged-in users respectively). The main page title can be hidden by setting both messages to empty (or only either of them if the title should still be displayed to logged-out or logged-in users).

How can I hide the table of contents?

The table of contents (TOC) is automatically shown once there are four or more headings in the article. There are multiple ways to hide it.

For one page
Place the magic word __NOTOC__ in the page's wikitext.
For all pages
Install Extension:NoTOC
or
Add the following rule to MediaWiki:Common.css: 
.toc, #toc { display: none; }
Per user
Users can add the same CSS rule to their common.css personal stylesheet.

How do I change the interface text?

Interface text is altered using the MediaWiki namespace. For each deviation from the default in the site language there is a page MediaWiki:Englishmessagename, and for each deviation from the default in each other language a page MediaWiki:Englishmessagename/languagecode. (Since release 1.9 there are no pages for messages equal to the default.). On creation of a page the edit box autofills with the default. When creating a page to override the default it is useful to first save the default version, to allow diffs with it. See also Help:System message .

How do I edit error messages?

Special:Allmessages contains a complete list of messages (error or otherwise), that can be edited.

You may also add ?uselang=qqx or &uselang=qqx to a URL which will display the name of each messages in the interface.

How do I change the interface language?

To change the default interface language, alter the value of $wgLanguageCode in LocalSettings.php, for example 

$wgLanguageCode = "fr";

You may also need to bypass your browser's cache to see the changes.

The new default interface language will be applied to all users who haven't ever customised it.

If you want to provide users the possibility to create and choose pages and interface elements in languages other than the default one of the wiki, you need the Translate extension, which can make your wiki multilingual.

If you want to change the language settings for all existing users, use the userOptions.php maintenance script. For instance, to have all users with English set use French instead, run: 

php userOptions.php language --old en --new fr

How do I remove the article/edit etc tabs?

For a little more control see: User:Subfader/Hide_page_tabs

Edit MediaWiki:Common.css on your wiki, and add this: 

li#ca-edit { display: none; }

See the page source for the various #ca-* ids used in the content tabs.

This will only work for Monobook and derived skins such as Modern and Vector (the default skin), and doesn't actually stop people from editing. To do that, see Manual:User rights .

How do I add/remove tabs throughout my wiki?

See Manual:User group CSS and JavaScript

How do I remove a tab on only one page?

MediaWiki version:
≥ 1.9

For example, to remove the Discussion (talk) page tab from the Main Page, on the MediaWiki:Common.css page add: 

body.page-Main_Page li#ca-talk { display: none !important; }

To modify MediaWiki:Common.css you must be an Interface administrator .

See also: Manual:Hide page tabs

How do I remove a tab on all pages

MediaWiki version:
≥ 1.9

For example, to remove the Discussion (talk) page tab on all wikipages, on the MediaWiki:Common.css page add: 

#ca-talk { display:none!important; }

Other tabs to remove are #ca-history, #ca-viewsource, #ca-view (Read tab), #ca-nstab-main (Page tab).

Other drop down menu items you can remove are #ca-watch, #ca-move, #ca-delete.

To modify MediaWiki:Common.css you must be an Interface administrator .

One option is to hide the link using the following CSS in the wiki page MediaWiki:Common.css in your wiki: 

#p-personal #pt-anonuserpage {
    display: none;
}


To remove the login / create account links from the personal_urls you can use this code in your LocalSettings.php to hook in and remove them: 

$wgHooks['SkinTemplateNavigation::Universal'][] = function ( $skinTemplate, &$links ) {
	unset( $links['user-menu']['login'] );
	unset( $links['user-menu']['login-private'] );
	unset( $links['user-menu']['createaccount'] );
};

How can I suppress actions and special pages?

To disable a specific special page (such as Special:SpecialPages), you may use: 

$wgSpecialPages['Name'] = DisabledSpecialPage::getCallback( 'Name', 'message' );

where Name is the canonical (English) name of the special page to disable, and message is the message to be shown to users when they try to access the special page.

To disable an action (such as edit), you may use: 

$wgActions['edit'] = false;

See API:Restricting API usage to disable an API module.

This is only the basic usages. Usually you may want to disable special pages, actions or API modules conditionally.

How do I change the footer?

See: Manual:Footer , Manual:Configuration settings#Copyright

How can I edit / remove the Powered by MediaWiki image (and possible other images) from the footer?

You can hide the Powered by MediaWiki image by adding the following to your wiki's MediaWiki:Common.css: 

#footer-poweredbyico { display: none; }

If you want to remove it completely, you can use $wgFooterIcons to remove it using this in your LocalSettings.php: 

unset( $wgFooterIcons['poweredby'] );

Note that this will also remove other powered-by icons, e.g. also the one coming from BlueSpice.

If you wish to change the icon images, urls, alt text, or add new icons please see $wgFooterIcons ' documentation.

Install DiscussionTools to enable automatic reply links on talk pages.

How can I change what the ‎<title> of each page is? Where do I make changes?

Most of the text that you want to change can be found in the namespace of MediaWiki.

In order to change titles, texts, announcements, etc., go to Special:AllMessages, where you will see the text associated with the pages you wish to change. You need to log in as an administrator to edit the protected entries in the MediaWiki namespace.

If you want to change the title in your browser, you need to edit MediaWiki:Pagetitle. Go there and edit it just like you would any other page in your wiki.

In recent versions of MediaWiki, MediaWiki:Pagetitle is $1 - {{SITENAME}} by default. If {{SITENAME}} is producing the wrong text for you, you need to set $wgSitename in your LocalSettings.php.

Don't forget to clear your browser cache after you change your settings.

Does MediaWiki automatically capitalize the first letter of $wgSitename?

Yes. This can be changed using the $wgCapitalLinks configuration setting.

See Manual:$wgExternalLinkTarget

How can I suppress MediaWiki from formatting URLs, tags, etc?

Put "‎<nowiki>‎</nowiki>" tags around the URL or tag.

Example: 

svn co <nowiki>http://svn.example.com/myproject/</nowiki>

Produces:
svn co http://svn.example.com/myproject/

How can I force users to preview before they save?

See: Manual:Force preview , Extension:ForcePreview

How do I add more buttons on the edit page?

See: Manual:Custom edit buttons

How can I get more special characters or tags clickable on the edit page?

For adding more selectable special characters, etc., below the edit field, see Extension:CharInsert .

How can I use a different skin on my wiki?

See Manual:$wgDefaultSkin for more information on configuring your default skin.

Edit the page MediaWiki:Print.css on your wiki and add the following code there: 

#content a.external.text:after,
#content a.external.autonumber:after {
	content: none;
}

This will override the styles defined in the CSS files coming with the MediaWiki source code. For more information, see Manual:CSS .

If instead you want to have the external links underlined in the printable version, then also add the following code: 

#content a.external {
    text-decoration: underline !important;
}

How do I print footnotes at the bottom of each printed page?

Try this StackOverflow solution: Printed HTML per-page footnotes

How do I change the text of the article (page name) tab of my wiki's main page?

To change the text of the tab, as one example used in Wikipedia, you first open the page "MediaWiki:Mainpage-nstab".

After you've done that, click Edit and type in the edit box the text you want to be seen later on the main page - that's it. Don't forget to save the page as well.

How do I change the background color?

To change the background color of the MediaWiki interface outside of the page content and tabs, add the following CSS to the MediaWiki page [[MediaWiki:Common.css]]: 

/* Changes the background color of the bottom and left of each page, up to behind half of the logo: */
body {
  background: red;
}

/* Changes the background color behind the top half of the logo and at top of each page: */
#mw-page-base {
  background: red;
}

This will change the background color outside of the tabs, search, and page content to red. See Manual:CSS for more information.

How do I load external fonts?

This example refers to Google Fonts, a repository of free open-source fonts that you can use with MediaWiki. Go to https://fonts.google.com/, find fonts that you like, and select them by clicking the "plus" (+) icon. Select one or more fonts to be added. Click the tab for the pop-up notification, and then select "@IMPORT". Copy and paste the resulting CSS into [[MediaWiki:Common.css]]. The examples below use Noto Sans and Noto Serif. They are default fonts for Android operating system and have good support for Unicode text. 

@import url( 'https://fonts.googleapis.com/css?family=Noto+Sans|Noto+Serif' );

/* Changes the default font used for MediaWiki to Noto Sans (does not include headings or monospaced text): */
body {
  font-family: "Noto Sans", sans-serif;
}

/* Changes the default font used for MediaWiki headings to Noto Serif: */
#content h1, 
#content h2 {
  font-family: "Noto Serif", serif;
}

How to hide the "Your edit was saved" notification?

Edit the wiki page MediaWiki:Common.css on your wiki to include the line .postedit {display: none;}. See Manual:Interface/Stylesheets for more information.

Basic usage

How do I edit a page?

To edit a page, simply click the edit link that appears on each page. Using the default Vector skin, this is in the form of a tab at the top of the page. A form will appear, containing the existing markup. When you have finished making modifications, click the Save button to commit your changes.

See also: Help:Editing pages

How do I create a new page?

There are several ways to create a new page:

  • Create a link to the page on another page, then click on the red link which appears
  • Browse to the intended location of the page, e.g. http://www.example.com/index.php?title=New_page and click on the "Edit", "Create" or "Create source" link.

On some wikis, a failed search for a page will contain a link which allows you to edit that page.

How do I delete an old version of a page?

Old versions of page data are retained in the database and can be accessed via the page history features. This is useful for reviewing changes and correcting or reverting undesirable ones, but in some cases, administrators might want to make this information unavailable, for legal reasons, or to reduce the size of the database.

  • Administrators can delete an old revision of a page by deleting the page, and then selectively undeleting revisions to be kept
  • You can enable the core RevisionDelete feature that allows privileged users to remove single revisions from page histories.

How do I use oversight/delete revisions in the page history?

See: RevisionDelete

You can also delete a page, and then restore only the revisions you want.

Are there any editing tutorials available?

There are several editing tutorials available, mostly on Wikimedia sister projects, such as Wikipedia. There are also markup references, etc. available on Meta.

How do I view the printable form of a page?

See also: Help:Printing

MediaWiki includes stylesheets which automatically style a page appropriately when it is printed; using the print or print preview function within your browser ought to render the page in a printable form.

You can also view this printable form using the printable version link in the sidebar under Toolbox or Print/export if using the Collection extension.

How do I use templates?

See Help:Templates

Can I use media (images, video, audio, etc.) from Wikimedia Commons in my installed version of MediaWiki?

Yes, this is encouraged through the use of Manual:$wgUseInstantCommons .

How do I use a template as a signature?

When you look at your preferences, you see a check box for "raw signature." But the field will only take a certain number of characters. What if you want more?

You will need to create two pages, possibly in your userspace.

  1. Create the first page (FIRST PAGE)
  2. Go to your preferences, check "raw signature" and put {{FIRST PAGE}} in the signature. Simpan
  3. Create a second page (SECOND PAGE) (possibly a sub-page of the first)
  4. Go back to the first page (FIRST PAGE) and do {{SECOND PAGE}}
  5. Go to the second page (SECOND PAGE) and place the code you wish to have for your signature.

If you don't have this structure, you will still be inserting all your signature code into the raw code wherever your signature is used, because the software will insert "SUBST" in your preferences. You may not mind this, in which case you only need one page. If you want the raw code to only display {{FIRST PAGE}}, which looks a lot cleaner, then you need to use the two-page structure.

How do I add the sandbox functionality to my installation of the wiki?

In wiki terms, a sandbox is simply a "play pen"; a page which users can mess about in. This is an ordinary page created in the normal manner, and can be located wherever you like. There is no special sandbox functionality built into MediaWiki.

Users often inquire about the Wikipedia sandboxes, which seem to be self-emptying. This is not quite correct; there are a number of volunteers who run bots to clean these up and return them to a certain state at regular time intervals.

See also Extension:PautanKotakpasir which will add a link to user's personal sandbox (i.e. a subpage of personal user page) to personal tools menu.

How do I make my wiki serve all languages?

Wiki importing

Importing from MediaWiki XML dumps

See: Manual:Importing XML dumps

Importing from other types of wiki software

Main page: Manual:Importing external content

Importing from other types of files

There are a variety of tools available to help convert content from HTML (and other formats) to MediaWiki markup.

Developer and SysAdmin tools
End-user tools
  • wikEd - a text editor for MediaWiki that can import HTML (including Microsoft Word-generated HTML.)
Instructions

Templates imported from other wikis (such as Wikipedia) don't work for me

You probably need to install some extensions used on the source wiki, such as Scribunto , TemplateStyles , ParserFunctions or sometimes Cite . Also, make sure that you copied all site CSS and JavaScript required by the template.

Customising further

I want to have multiple wikis, but only require registration once

  • If you're starting from scratch or you're switching from one wiki to multiple, you can use $wgSharedDB and $wgSharedTables to have all wikis share the user table of the "main" wiki.

You can share other tables as well, as long as they don't contain any data dependent on non-shared tables or data specific to one wiki. See Manual:Shared database for examples and more information.

  • If your wikis are already established and you want to switch to a single sign-on, you can use the CentralAuth extension.

It has a few more features than a shared user table, but it's more difficult to configure and it's tailored toward a Wikimedia-style setup. However, it is easier than attempting to completely merge multiple user tables into one.

How can I allow use of HTML tags?

See Manual:$wgRawHtml as well as Manual:$wgGroupPermissions dan Manual:Preventing access .

Caution! Caution: This can be easily abused to attack users

See HTML restriction for ways to make this safer.

How do I fix problems or add features to MediaWiki?

The basic steps to improving MediaWiki (that is, becoming a MediaWiki developer) are:

  • Download the Git "clone" of the MediaWiki source code
  • Get a server, a database, and PHP running on your computer (this can be annoying, so please ask for help if something isn't working)
  • Get MediaWiki running on your computer off that Git checkout (can be annoying as well, so, ditto)
  • Fix the problem or add the feature you were thinking of
  • Edit the source code of the relevant file(s) to fix the problem

How do I run a bot?

How do I add meta tags?

The OutputPage class includes an addMeta method which can be used to add meta tags. The RequestContext can be used to get the relevant OutputPage object. 

$out->addMeta ( 'description', 'This is a meta description.' );

Why...?

…is the Help namespace empty?

The Help namespace currently ships in a blank state. It's up to you how much or how little help you give to your site visitors and whether this relates to other aspects of your site. Obviously you can easily link your visitors to help resources elsewhere.

We don't currently have a clean, internationalised set of help pages under a free license. However, if you want to copy in some help information onto your site, about how to use a wiki (a MediaWiki powered wiki) you are free to copy the Bantuan:Kandungan from this wiki. This set of pages have been deliberately created for this purpose, with wiki-neutral information, and no license restrictions. See Project:PD help .

…are some of my images not showing up after an upgrade?

Several users have reported that, following an upgrade or a moving of their wiki, several images fail to be shown inline. The files exist, and the image description pages show a MIME type of unknowncode>/unknown and, in some cases, a warning about potentially dangerous files.

To fix this, run the maintenance/rebuildImages.php script from the command line. This will set MIME information for each file in the database.

MediaWiki 1.21 and newer implements responsive images. Due to a bug, if the server locale is set to one that uses commas instead of dots for representing a decimal point, images may not render on some browsers/devices. This can be confirmed by inspecting a thumbnail of a medium or big image on a page with the browser tools, looking at the HTML code, and see if the srcset attribute contains commas instead of dots when representing the 1.5x value.

…are all PNG files not being turned into thumbnails?

After upgrading to a more recent version of PHP, it is possible a different MimeMagic.php function is being used to detect file MIME types, particularly the built-in PHP function mime_content_type, which fails to detect PNG files. Search the web for mime_content_type png for information on fixing this bug at the PHP level, possibly by editing your magic.mime file.

See File is corrupt or has an invalid extension for more info.

…can't I download MediaWiki 1.43?

MediaWiki 1.43 is in a development state at present, and has not been packaged into a general release. The code can be downloaded from Git if desired. Or, if you want the latest development version packaged as an archive, get it at mediawiki-master.tar.gz (GitHub).

…doesn't this work? It works on Wikipedia!

Wikipedia and other Wikimedia web sites use the current version of the code in development; at present, this is MediaWiki 1.44.0-wmf.6 (d77bde6), pulled from the current development branch. Coupled with the use of several extensions, this means that functionality between these wikis and your particular setup may differ.

  • To check what version a Wikimedia wiki is running, as well as what extensions are installed, visit the Special:Version page for that wiki

…do I get a 403 Forbidden error after setting permissions on my Fedora system?

Fedora enables SELinux by default. Instructions for setting SELinux permissions for MediaWiki are available.

…do I get Installing some external dependencies (e.g. via composer) is required?

Many hosting providers only handle zip archives, and we only provide gz compressed tar archives, thus the archives has to be recompressed before uploading. This should not be a hurdle, but it seems like some archive tools occasionally fail to include all files in large archives. When this happen the vendor folder is left out, leaving the user with the rather non-explanatory error message.

Use a command line tool when recompressing the tar archive into a zip archive.

…do I get logged out constantly?

This is probably related to cookies or session data. See Log in problems for information.

If this is happening constantly to all users, it probably means that caching is misconfigured. Setting $wgSessionCacheType = CACHE_DB; can be used to determine if caching is the cause of the problem. If that solves the problem, you should still investigate what is wrong with your caching configuration.

…is it a good idea to keep user accounts?

At many times you just want to remove a user account out of the wiki either because it belonged to a spammer account or you just feel like it. The appropriate choice is to block the account or rename it if needed. Here is why:

Do I just remove this row from the user table?

Rob Church posted the following regarding this issue on the wikitech-l mailing list:

If the user has made edits, then removing rows from the user table cause theoretical loss of referential integrity.

Now, to be honest with you, I can't think of any conditions where this would cause an actual problem; "undefined behaviour" is the phrase we use.

What I'd suggest doing, to be on the safe side, is running a couple of quick updates against the database: 

UPDATE revision SET rev_user = 0 WHERE rev_user = <current_user_id>

UPDATE archive SET ar_user = 0 WHERE ar_user = <current_user_id>

What this will do is cause MediaWiki to treat the revisions as having been made anonymously when generating things like page histories, which should eliminate any problems caused by these routines attempting to check user details from other tables.

If the user has caused log entries, i.e. rows in the logging table, or uploaded images, then the situation becomes trickier, as you'll have to start mopping up all the rows everywhere and it could become a bit of a mess, so if the user's done anything other than edit, I would strongly recommend just blocking them indefinitely.

If the username is offensive or undesirable, then you could consider renaming it using the RenameUser extension.

Another option is to give Admins the 'hideuser' right, and indefinitely block the user with the Hide username from edits and lists option selected.

Extension:UserMerge is also useful.

…is the number of pages so low on Special:Statistics?

By default, $wgArticleCountMethod is set to link. This means the number of "Content pages" on the Special:Statistics page only counts pages which include at least one internal link. This can be changed by setting $wgArticleCountMethod to any. Afterwards, run updateArticleCount.php and/or initSiteStats.php . (On Wikimedia websites, initSiteStats.php is run on the 1st and 15th of each month.) There might still be wrong behavior, see for example phab:T212706.

Anti-spam

How do I use $wgSpamRegex to block more than one string?

$wgSpamRegex is a powerful filter for page content. Adding multiple items to the regex, however, can be awkward. Consider this snippet: 

$wgSpamRegexLines[] = 'display\s*:\s*none';
$wgSpamRegexLines[] = 'overflow\s*:\s*auto';
[...]
$wgSpamRegex = '/(' . implode( '|', $wgSpamRegexLines ) . ')/i';

This example code allows convenient addition of additional items to the regex without fiddling about each time. It also demonstrates two popular filters, which block some of the most common spam attacks.

Are there additional ways to fight spam?

Anti-vandalism

Where now?

I've found a bug or have a feature request. Where do I post it?

Bugs and feature requests should be posted on Phabricator . See How to report a bug.

I'm getting a strange error. What now?

I tried that but it didn't work

I had a problem, I came to this page and it told me how to fix it. But it didn't work, the problem is still there!!!!

Nine times out of ten this is because you didn't clear your cache. The simple test for this is to request a page that hasn't been requested before. Select the part of the URL in the address bar that contains the page title (e.g. Main_Page). Twiddle your fingers on the keyboard for a while, hit enter. Check if the problem is on that page too.

MediaWiki uses both a server-side cache and a client-side cache, so clearing your browser cache is often not enough. See the relevant entry above for more details.

Here are some other things to check:

  • Were you editing the right file? Try inserting some garbage into the file you edited, does it break anything?
    • A great debugging tool in this case is to create a file called phpinfo.php, containing only <?php phpinfo() ?>.

Upload it into your web directory and invoke it with your browser. Check the document root and the path to php.ini.

  • Were you editing the right part of the file?

Did you create a duplicate entry in php.ini? Add new settings to the end of LocalSettings.php, not to the beginning.

  • If you created a .htaccess, are you sure AllowOverrides is on?

Ask your hosting provider.

I have a question not answered here. Where do I go next?
