UploadWizard is an extension that allows a user to upload multiple files with a step-by-step JavaScript wizard. It was originally designed by Guillaume Paumier as part of the Multimedia usability project and developed by Neil Kandalgaonkar, and has evolved since then.

Installation[edit | edit source]

Enabling uploads and thumbnails[edit | edit source]

Your MediaWiki will need to be capable of hosting media files and creating thumbnails (smaller previews of media files). If you can upload images and see smaller previews on their File page, you're already ready. If not, for full instructions, see the manual page on image administrationManual:Image administration, particularly image thumbnailingManual:Image administration#Image thumbnailing.

Quick start for GNU/Linux or Mac OS X users:

  • Make sure that the images directory is writable by your web server.
  • Install the ImageMagick libraries and binaries.
  • Add the following configuration to LocalSettings.php:
$wgEnableUploads = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = <path to your convert command>;  # Only needs to be set if different from /usr/bin/convert

require_once( "$IP/extensions/UploadWizard/UploadWizard.php" );

You also need to change the following core configuration variable.

// Needed to make UploadWizard work in IE, see bug 39877
$wgApiFrameOptions = 'SAMEORIGIN';

You should also install the EventLogging extension. This is used only if you use the campaigns feature, and should be made a soft dependency at some point in the future.

Enabling Flickr uploads[edit | edit source]

You can also use UploadWizard to transfer files directly from Flickr. To enable this option, first you'll need to get an API key from Flickr:

  1. Go to http://www.flickr.com/services/api/
  2. Click on API Keys
  3. Log in with your Yahoo/Flickr username and password
  4. Sign up for a key

Once you have a key, add the following to your LocalSettings.php:

$wgAllowCopyUploads = true;
$wgGroupPermissions['user']['upload_by_url'] = true; // to allow for all registered users

$wgUploadWizardConfig = array(
    'flickrApiUrl' => 'https://secure.flickr.com/services/rest/?',
    'flickrApiKey' => 'XXXXXXXXXXXXXXX',

You may also want to limit the upload domains specifically to Flickr:

$wgCopyUploadsDomains = array( '*.flickr.com', '*.staticflickr.com' );

Updating from versions before 07/2013[edit | edit source]

The following is essentially important if you made use of the Campaign feature:

  • Update MediaWiki core to version 1.22 or later
  • Check your custom configuration (LocalSettings.php) against the new default config. Parameters like automatically added categories changed (autoCategoriesautoAdd => array( categories ).
  • Install Extension:EventLogging.
  • Run
    $ php extensions/UploadWizard/maintenance/migrateCampaigns.php

Other configuration[edit | edit source]

  • You need to have InstantCommons enabled in order to access the licensing tutorial. To enable InstantCommons add
    $wgUseInstantCommons = true;
    to LocalSettings.php.
  • You may want to set
    $wgUploadNavigationUrl = '/wiki/Special:UploadWizard';
    in LocalSettings.php, where /wiki/ is the correct path for your wiki. A more general way of doing this that works for whatever path configuration you have, but that requires PHP 5.3 or later is:
$wgExtensionFunctions[] = function() {
	$GLOBALS['wgUploadNavigationUrl'] = SpecialPage::getTitleFor( 'UploadWizard' )->getLocalURL();
	return true;

This modifies the sidebar's "Upload file" link - probably in other places as well. More at Manual:$wgUploadNavigationUrl.

Several other options are available through a configuration array. For example:

$wgUploadWizardConfig = array(
	'debug' => false,
	'autoAdd' => array(
	 	'wikitext' => array( 'This file was uploaded with the UploadWizard extension.' ),
	'feedbackPage' => 'Feedback about UploadWizard',
	'altUploadForm' => 'Special:Upload',
	'fallbackToAltUploadForm' => false,
	'enableFormData' => true,  # Should FileAPI uploads be used on supported browsers?
	'enableMultipleFiles' => true,
	'enableMultiFileSelect' => false,
	'tutorial' => array(
	 	'skip' => false
        'fileExtensions' => $wgFileExtensions //omitting this can cause errors

Note Note: This is just an example configuration setting. See the "UploadWizard.config.php" file (starting around line 60) for many more options to the $wgUploadWizardConfig array.

Usage[edit | edit source]

URL arguments[edit | edit source]

There are several url arguments that can be specified to alter the behaviour of the UploadWizard:

  • campaign: Specifies which upload campaign to use.
  • skiptutorial: Sets if the licensing tutorial should be skipped or not. The value should be "1" or "true" to skip.
  • id: Sets the initial value for the id field.
  • description: Sets the initial value for the description field.
  • lat: Sets the initial value for the latitude field.
  • lon: Sets the initial value for the longitude field.
  • alt: Sets the initial value for the altitude field.
  • categories: Sets the initial value for the categories field, multiple categories seperated by |.
  • fields: The initial value of additional fields defined by a campaign. Values of multiple fields must be passed in the exact same order as defined in the campaign.
(e. g. fields[]=value_first&fields[]=value_second)

These arguments can be specified as follows: if you have an argument named "campaign" and want to provide the value "foobar", then append campaign=foobar to the url. For example wiki/Special:UploadWizard?campaign=foobar or w/index.php?title=Special:UploadWizard&campaign=foobar.

Object references[edit | edit source]

Upload Wizard provides a way to store “object references” - references to list templates in Wiki pages - in the file description page. These may be used by bots to insert a thumbnail image into a list page. A bot that is doing this for monument lists of German Wikipedia is running on tool labs. Its code is hosted on GitHub. Though its purpose is to update monument lists on Wikipedia it can be adopted to serve in different scenarios.

This feature uses the parameters objref and updateList. If both parameters are passed, the Upload Wizard shows a checkbox for each upload, which can be used to select the image that the object reference is added to. If the parameter updateList is omitted, the checkboxes will be disabled and an additional notice is being displayed stating that an image for the object already exists in the list.

  • objref: Specifies an object reference that can be used to update a page with a thumbnail of an uploaded image. Passing this parameter is expected in the following format objref=prefix|page_title|object_id
    • prefix - Interwiki or interlanguage prefix as defined per Special:Interwiki. The prefix must be defined in order to make this work.
    • page_title - The title of the page the object is listed on.
    • object_id - A unique identifier of the object for a bot to update
  • updateList: Specifies whether a list page should be updated at all. Set to any value, this parameter enables a checkbox

Testing[edit | edit source]

If you're testing UploadWizard for whatever reason, and you've run out of "real" images to upload as test cases, you can always use the handy MediaWiki utility for creating test images. Open a terminal emulator, get into a directory where you want to store a bunch of test JPG files, and run

$ php path/to/mediawiki/tests/phpunit/includes/api/generateRandomImages.php

Here's a Bash script that should make it easier to do all of this without much trouble. It's a good idea to put this in your PATH and/or make a handy shortcut to it somewhere that will make it trivial to update your images with new ones.


# Declare some paths (easier to configure)

# Get to the pic path, and remove old test images
rm *.jpg

# Run the generate script three times to give us a bunch of images
php $MW_INSTALL_PATH/tests/phpunit/includes/api/generateRandomImages.php
php $MW_INSTALL_PATH/tests/phpunit/includes/api/generateRandomImages.php
php $MW_INSTALL_PATH/tests/phpunit/includes/api/generateRandomImages.php

Templates[edit | edit source]

WARNING: This list is not complete and more templates are required, otherwise you will end with SCRIPT error or other error messages not in English!

Upload Wizard will insert a few templates into generated file description pages, which need to exist on the wiki in order for the description pages to be rendered correctly. The templates used include:

Development status[edit | edit source]

While we feel that this is ready for others to use, so far, this extension has mostly been used only on Wikimedia wikis. We'd like to get reports from other MediaWiki installations as well.
