The MultimediaViewer extension gives the user of a wiki a different interface for viewing full-size, or nearly full-size, images in their browser without extraneous page loads or confusing interstitial pages.

Installation

Option A: use Vagrant. See the MediaWiki-Vagrant page for instructions to get a MediaWiki installation going with a Vagrant virtual machine system.

Then do vagrant enable-role multimediaviewer and then vagrant provision.

Option B: install manually.

First, consider installing Extension:BetaFeatures . It may be helpful to hide the media viewer feature behind a preference. If you don't install this, it will be enabled everywhere. MultimediaViewer uses the GetBetaFeaturePreferences hook, which is created and run from BetaFeatures, to register this preference.

You'll also likely want to download Extension:CommonsMetadata - it's not a hard requirement, but without it you won't get very much information in your lightboxes.


  • Téléchargez et placez le(s) fichiers (s) dans un répertoire appelé MultimediaViewer dans votre dossier extensions/.
  • Ajoutez le code suivant à la fin de votre fichier LocalSettings.php :
    wfLoadExtension( 'MultimediaViewer' );
    
  • Yes Fait – Accédez à Special:Version sur votre wiki pour vérifier que l'extension a bien été installée.

Pour les utilisateurs de MediaWiki 1.24 ou précédents :

Les instructions ci-dessous décrivent la nouvelle procédure pour installer cette extension en utilisant wfLoadExtension() Si vous avez besoin d'installer cette extension sur les précédentes versions de MediaWiki (1.24 ou précédent), à la place de wfLoadExtension( 'MultimediaViewer' );, vous devez utiliser :

require_once "$IP/extensions/MultimediaViewer/MultimediaViewer.php";

Configuration

  • $wgMediaViewerIsInBeta will register a preference with BetaFeatures if set to "true"
  • $wgMediaViewerEnableByDefault and $wgMediaViewerEnableByDefaultForAnonymous will determine whether MMV is enabled by default for everyone and for anonymous users, respectively. They both default to true. $wgDefaultUserOptions['multimediaviewer-enable'] = 1; can be used as a replacement for $wgMediaViewerEnableByDefault.
  • $wgMediaViewerUseThumbnailGuessing will improve performance when enabled, but can be fragile depending on how the wiki is set up (it will probably work fine if you use a 404 handler).
Forced download

To ensure files are offered for download and not viewed in the user's browser following a click on the Download … button, the server has to be configured, except when using vagrant:

If the requested URL to an image directory contains the download query parameter, the Content-Disposition-header must be set to attachment. This can be achieved in Apache and compatible servers using mod_rewrite and mod_headers in a .htaccess file. Varnish configuration can look like this.

Using the extension

First thing, before testing, is to make sure you're logged in and you have the preference enabled: Log in to the wiki and go to Special:Preferences, then visit the "Beta features" tab and check the appropriate box.

Next, go to a page that has a thumbnail on it. Try clicking on the image or on the "expand" icon near it. The lightbox should pop up and give you a bigger view of the image.

If you'd prefer, there's an exported test environment that you can use via Special:Import to quickly set up a suitable testing environment.

Extending with user scripts

If you want to add functionality, you'll have to dig around in the classes and change the functionality pretty manually. We'll work on making this a nicer experience, but given the class and method hierarchy we've built, we think it's not terribly difficult right now.

HOWEVER, you should avoid doing this too much. If things change internally, then your code might break in unexpected ways, and you (and your users) will be surprised. Don't let that happen, and wait for a more stable way to extend the product.

See /Extension:Metadata for an example.

Templates

Multimedia Viewer and Upload Wizard needs several templates to show data of photos. Just save this code in a xml file and import it in your wiki.
