Επεκτάσεις για να αλλάξετε το πώς δείχνει και πώς δουλεύει το MediaWiki


 * Οι χρήστες του Wiki μπορούν να ψάξουν τις ήδη υπάρχουσες επεκτάσεις.
 * Ο διαχειριστής μπορεί να εγκαταστήσει (ή να αφαιρέσει) επεκτάσεις από το MediaWiki που διαχειρίζεται
 * Developers can write new extensions or improve or maintain extensions.

While some extensions are maintained by MediaWiki developers, others were written by third-party developers. As a result, many have bugs, and they are not all guaranteed to be compatible with each other. Some are unmaintained; not all extensions work on all versions of MediaWiki. Χρησιμοποιείτε τις επεκτάσεις, και ιδιαίτερα όσες έχουν σημανθεί ως επισφαλείς, με δική σας ευθύνη. If you are using an extension that requires patches to the core software, be sure to back up your database. This helps avoid the risk of breaking your wiki.

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.



Ελέγχοντας εγκατεστημένες επεκτάσεις
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.

Popular extensions
There are a number of ways of finding popular extensions.

The first set is those that are bundled with MediaWiki (a list that is reviewed regularly, and to which anyone can suggested an addition).

Extensions that are downloaded from MediaWiki.org via the ExtensionDistributor mechanism have some statistics gathered. The top 15 most downloaded extensions are listed at Special:ExtensionDistributor, and applicable extensions have their download count shown in their infobox. Note that these numbers do not account for alternate ways of installing extensions, such as via Git or Composer.

A third option is to look at WikiApiary's counts of wikis that extensions are installed on. This has the advantage of representing actual installations and not just downloads (i.e. it queries the wiki's APIs), but it is also (as of 2023) not completely up to date. It also doesn't count installations on private wikis.



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


 * 1) Πριν ξεκινήσετε
 * Πολλές επεκτάσεις παρέχουν οδηγίες σχεδιασμένες για εγκατάσταση με την χρήση εντολών unix. Χρειάζεστε πρόσβαση φλοιού (SSH) για να εισάγετε εκείνες τις εντολές στις σελίδες βοήθειας των επεκτάσεων.
 * 1) Κατεβάστε την επέκταση.
 * 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) Εγκαταστήστε την επέκταση..
 * 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,.



Αναβαθμίζοντας μια επέκταση
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) Κατεβάστε τη νέα έκδοση της επέκτασης
 * 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.
