Upload dialog/de

The upload dialog (also known as foreign upload tool or cross-wiki upload tool) is available in and wikitext editor on Wikimedia wikis. It's not available for users who disabled "enhanced editing toolbar" or "wizards for inserting links, tables" in their preferences. It can also be used outside of these contexts, like in a Gadget or extension. Siehe die API-Dokumentation für Anweisungen und Details.

The dialog allows any registered user to upload a file to the wiki directly from the editor, guiding them through the process. On Wikimedia wikis, it is configured to only allow self-made files under the CC BY-SA license and upload them from any Wikimedia wiki to Wikimedia Commons. Its interface is inspired by UploadWizard, but much more limited (in particular, it only allows uploading one file at a time and only allows providing a simple description in one language).

While it's a part of MediaWiki core, the upload dialog is not currently available from the default wikitext editor. You need to install one of the editing interface extensions to use it: or.

Afterwards the user returns back to the previous dialog, where they can fill in the thumbnail caption and other details.

Configuration (for wiki sysadmins)
The dialog should be available by default on any wiki using or newer that has. Note that the extension is required for the tool to be available from the wikitext editing toolbar (it is also available in ). Starting with MediaWiki 1.28 (but not 1.27), it can be disabled by setting to.

Some aspects of the dialog (fields to display, the licensing options, special formatting for the file page and upload comment) can be configured using.

By default the uploads go to the local wiki. To configure cross-wiki uploads, you'll need to configure and  on all of the "source" wikis and  on the "target" wiki. Only the target wiki has to have uploads enabled. Note that the configuration for the target wiki will be used, not the source wiki.

Wikimedia
Wikimedia wikis are configured to perform cross-wiki uploads to Wikimedia Commons. Additionally, https://test2.wikipedia.org/ is configured to perform uploads to https://test.wikipedia.org/. See the configuration variables mentioned above in InitialiseSettings.php, CommonSettings.php, filebackend.php.

Some statistics on usage in 2017 from VisualEditor and WikiEditor are available (about 3000 uploads per day, of which some 25 % from WikiEditor).

API documentation
The upload dialog is implemented using mw.ForeignStructuredUpload and mw.ForeignStructuredUpload.BookletLayout, which build upon simpler components. See OOUI/Windows for documentation about OOUI dialogs.
