The Extension Manager plugin allows superusers to administer installed plugins and templates and install new ones.

The Extension Manager is accessible from the admin screen (Login as superuser, click “Admin” and choose “Extension Manager”).

The Installed Plugins listing is the default action of the Extension Manager. The second tab lists the Installed templates. Each plugin or template is shown in its own row. The right hand side column contains action buttons like Disable/Enable, Install/Uninstall/Re-install and Update.

Plugins and templates with gray font are currently disabled.

To disable or enable a plugin, you use the Disable and Enable buttons on the right hand side.

Disabled plugins will no longer be loaded by DokuWiki, their stylesheets and JavaScript won't be loaded, and their syntax will no longer have any effect.

Pressing the arrow button in the rightbottom corner will display some basic information about the chosen plugin read from two sources, namely

1. DokuWiki's online repositories
   • for plugins: https://www.dokuwiki.org/plugin
   • for templates: https://www.dokuwiki.org/template
2. the local info file that is installed with an extension
   • for plugins compare plugin info
   • for templates compare template info

The information of the repository is shown firstly, next it is completed with some info of the local info file. This local info can be outdated.

Extensions can add useful features, but please be aware that installing 3rd party code may pose a security risk.

In the third tab “Search and Install” of the Extension manager you can search the extension repositories on dokuwiki.org for plugins and templates and install them using the “Install” button.

Plugins and templates not provided via the online repository or a version from a different download location can be installed via the fourth tab “Manual Install”. You can provide a url or choose an archive from your computer.

Depending on the automatically gathered information about installed extensions you may see an additional button for “Re-Install” or “Update”.

If you have installed an extension that shares the same name as one in the online repository but is a different one, do not use this feature for it.

You will see no such button for extensions that are not available in the online repository. This may be due to end of support, never having been added to the repository, or use of an alternative installation source. The latter especially for extensions that are installed using Git.

Re-Installing may be useful if you are not sure if something may have spoiled your extension.

When you press “Update” the Extension Manager will use the Download URL as provided via the online repository for retrieving updates. The extension manager will re-download the extension and install it again, overwriting the older version.

For the update process to work properly it is necessary that the date “Last updated on” in the Dokuwiki Extension repository equals the date in the file plugin.info.txt for plugins and template.info.txt for templates in the source tarbal/zipfile. If this is not the case: the update will not take place or the “Update” signal persists.

If an extension is updated, the Extension Manager will remove all the files listed in the deleted.files file if such a file is added to the extension. ===

Every installed extension has an “Uninstall” button.

If the installation of a defective or conflicting extension broke the “Uninstall” button or made your whole wiki unavailable, you can delete it by rem9oving the extension's directory (or ask your administrator to do so):

1. enter your wiki's filesystem
2. go to the /lib/tpl (for a template) or /lib/plugins folder
3. find the critical extension's folder and delete it

To be able to install and modify your extensions, the webserver needs to be able to write to the lib/plugins or the lib/tpl directory and all files below. Refer to permissions for details on how set file permissions on various systems.

The extension manager will detect missing file permissions and warn you when a plugin or a template could not be installed. You have to install extensions manually in this case, by downloading and unpacking them in lib/plugins or lib/tpl yourself.

If you try to install extensions using the automatic download and install tool and get the error message “No plugins found, or there has been an unknown problem during downloading and installing.”, then you should check:

• whether your server has activated the zlib (and/or bzip2) extension for php. To be sure, try the following: Download an extension, extract it, and rearchive it into a .tar file (without compression). Now try to use the download and install tool on that .tar file. If it works now, it is most likely that you just need to install the php-zlib package.
• whether your server is able to retrieve files over SSL (https://). Many extensions (correctly) use secure download links, including all those hosted on github. If your server is incorrectly setup to use SSL for file retrieval, try dropping SSL by deleting the 's' and changing the schema to 'http://'.

The rewrite of DokuWiki's Plugin Manager plugin was part of Google Summer of Code 2011 with Piyush Mishra as developer. Before inclusion it is rewritten by Michitux and Andi.
