Manual:Extensions/nl

Met extensies kunt u het uiterlijk en de werking van MediaWiki aanpassen.


 * Wiki-gebruikers kunnen door de extensies bladeren.
 * Systeembeheerder kunnen extensies installeren (en verwijderen) in de MediaWiki installaties die zij beheren.
 * Ontwikkelaars kunnen nieuwe extensies maken of extensies beheren.

Hoewel enkele extensies door MediaWiki ontwikkelaars worden onderhouden, zijn andere geschreven door derden. Hierdoor kunnen er extensies zijn met fouten of dat ze in een bepaalde combinatie niet goed werken. Enkele extensies worden niet beheerd en niet alle extensies werken op alle versies van de MediaWiki. Het gebruiken van welke extensie dan ook is voor uw eigen risico, voorkom het gebruik van extensies die hier als insecure zijn aangegeven. Als u een extensie gebruikt waarbij het nodig is om de code van de core te patchen (dus aanpassingen te doen in de standaardcode) zorg dan dat u daarvoor een back-up maakt van de code en de database. Dan kunt u in ieder geval nog terug.



Browsing extensions
You can browse to see the full range of extensions that have already been written. For information on installing these extensions or writing your own, see below.

Checking installed extensions
Only someone with administration access to the filesystem (and often the database too) on a server can install extensions for MediaWiki, but anyone can check which extensions are active on an instance of MediaWiki by accessing the Special:Version page. For example, these extensions are active in the English Wikipedia.

Installing an extension
MediaWiki is ready to accept extensions just after installation is finished. To add an extension follow these steps:


 * 1)  Before you start 
 * Many extensions provide instructions designed for installation using Unix commands. You require shell access (SSH) to enter these commands listed on the extension help pages.
 * 1)  Download your extension. 
 * Extension Distributor helps you to select and download most of the popular extensions.
 * Extensions are usually distributed as modular packages. They generally go in their own subdirectory of .  A list of extensions stored in the Wikimedia Git repository is located at git:mediawiki/extensions. Some extensions don't use version control and are not recommended.
 * Some extensions are also available in bundles, or package repositories.
 * 1)  Install your extension. .
 * At the end of the  file, add:
 * This line forces the PHP interpreter to read the extension file, and thereby make it accessible to MediaWiki.
 * Some extensions can conflict with maintenance scripts, for example if they directly access $_SERVER (not recommended).
 * In this case they can be wrapped in the conditional so maintenance scripts can still run.
 * The maintenance script will fail for any extension which requires customized namespaces which is included inside the conditional above such as,.
 * The maintenance script will fail for any extension which requires customized namespaces which is included inside the conditional above such as,.
 * The maintenance script will fail for any extension which requires customized namespaces which is included inside the conditional above such as,.

Upgrading an extension
Some extensions require to be updated whenever you update MediaWiki, while others work with multiple versions. To upgrade to a new version of an extension:

Do not remove the extension configuration present in LocalSettings.php Most extensions will mention if this script needs to be run or not. (Perform backup of your data before executing the script). If you don't have command line access, you can also use the web updater.
 * 1) Download the new version of the extension
 * 1) Replace all the extension files in the  directory with the new files.
 * 1) If the extension requires changes to the MediaWiki database, you will need to run the maintenance script.

Uninstalling an extension
Remove the line from LocalSettings.php with the extension name to uninstall it:


 * You must remove any lines pertaining to the configuration of the extension.
