Manual:Interface/Sidebar/it

MediaWiki:Barra laterale definisce la barra di navigazione, la quale ospita collegamenti ipertestuali verso le pagine più importanti del wiki e fornisce agli amministratori del sito un posto per aggiungere una collezione persistente di link. La maggioranza dei wiki, ad esempio, creeranno dei collegamenti alla pagina di discussione della loro comunità e ad alcuni strumenti utili.

Le skin Monobook e Vector posizionano la barra di navigazione in alto a sinistra (in alto a destra per le lingue da destra a sinistra) insieme alla barra di ricerca e alla casella degli strumenti (toolbox), ma il posizionamento potrebbe essere diverso in altre skin. Le sidebar sono nascoste per gli utenti del sito Mobile. This sidebar is not shown to users of the Mobile site (ie. the version of the site produced by Extension:MobileFrontend / Skin:MinervaNeue) - use the MobileMenu hook for that).

Customize the sidebar
To customize the MediaWiki:Sidebar on a wiki, you need first to be logged in with a user that has the editinterface permission - for administrators this is enabled by default. (For information on assigning a permission to groups or users, see .)

Then, use a link to a page on your wiki, but replace your wiki page's title (e.g. ) in the URL/Address bar with   and load that page - you should now see the current content of the sidebar. (You may need to use the syntax //yourdomain/yourwiki/index.php?title=MediaWiki:Sidebar&action=edit if you use long URLs.)

If the content of the sidebar has already been modified, you can simply click on the Edit or Edit source link, otherwise you may need to create the page first by clicking on Create or Create source.

Here is an example code for a sidebar:


 * navigation
 * mainpage|Accueil
 * Special:RecentChanges|Recent changes
 * new heading
 * portal-url|Forums
 * https://www.mediawiki.org|MediaWiki home

This example will result in the following sidebar:

Headings
The navigation bar can be split into sections, each with a heading of its own. The heading for each section is taken from the first-level list element ("navigation" and "new heading" in the example above).

If this text corresponds to the name of an interface message (an existing page of that title in the MediaWiki namespace), then the text of that page is used as a label; otherwise, the header title is used as-is.

To make sure the internationalized version is used, you can use the

** randompage-url|

Links
Second-level list elements are links ("mainpage|mainpage" in the example above), where the format is: ** target|link text


 * target
 * The link target can be the name of an interface message (page in the MediaWiki namespace) or wiki page, or an external link. In either case, the link can be internal, interwiki, or external. In some cases (such as links with the "&" character), an interface message is necessary. The link target cannot be made dependent on the interface language set in the preferences.


 * Algorithm followed:
 * Get the target text.
 * If there is an existing or default interface message with that name, use the content of that message instead of the target text.
 * If the output from the previous step is a valid URL (beginning with http:// or other URL protocol), the link will point to that URL.
 * Else, it will treat it as the link target of a wikilink (linking to that page name or interwiki).
 * In case it would end up linking to '-', the whole entry is removed from the sidebar (that's useful for removing an entry on all languages by changing the message holding the link).


 * Examples:


 * " " uses the text of MediaWiki:Portal-url (which contains " ").
 * " " links to Special:RecentChanges, since there is no interface message of that name.
 * " " links to w:Foo for the same reason.
 * " " links to https://www.mediawiki.org for the same reason.


 * link text
 * The link text can be the name of an interface message (page in the MediaWiki namespace) or plain text.
 * If the link text is the name of an existing or default interface message, the content of that message will be used. MediaWiki will check for localized versions; for example, if the current language is fr (French) and the link text is the interface message "forum", it will check for "forum/fr" before using "forum".
 * Otherwise, the link text is used as the target as-is.
 * Notice that the link text is not optional as in normal wiki links. If the link text is missing, the item is ignored.


 * Examples:


 * uses MediaWiki:Mainpage (which contains "").
 * uses "Recent changes", since there is no interface message of that name.

Order of elements
By default, the sidebar consists of elements in this order: navigation, search, toolbox, languages. The order can be changed (in MediaWiki 1.13+) by adding special keywords (SEARCH, TOOLBOX and LANGUAGES) to MediaWiki:Sidebar using the heading syntax. For example, the following code moves the search box to the top of the sidebar:
 * SEARCH
 * navigation
 * mainpage|mainpage
 * Special:Recentchanges|Recent changed
 * new heading
 * portal-url|portal
 * https://www.mediawiki.org|MediaWiki home

Tooltips and Accesskey
If you add an item to the sidebar, it will have no tooltip associated. But you can create such a tooltip by doing the following:
 * create a wiki page named "MediaWiki:Tooltip-n- "
 * and put the tooltip in that page.

Accesskeys can also be created by doing the following:


 * create a wiki page named "MediaWiki:Accesskey-n- "
 * and put the accesskey in that page.

Example:


 * uses MediaWiki:Tooltip-n-mainpage-description and MediaWiki:Accesskey-n-mainpage-description.

Translations
You can translate the strings, which you use, by editing the according pages in the MediaWiki namespace.

Example: The string, which will replace the item named "mainpage", is taken from MediaWiki:Mainpage. To set/change this text for users, who display your wiki in German, you can put the according text on the page MediaWiki:Mainpage/de.

That way you can easily translate these texts through the MediaWiki interface.

Please note that MediaWiki will by default use the content of the Sidebar page in that language, which corresponds to the default language of your wiki. So, if your wiki e.g. uses French as its default language, edit MediaWiki:Mainpage/fr in order to show a modified sidebar to all users, who have not changed their language setting and to all anonymous users.

For more advanced translation, see.

Advanced customization
The sidebar can be fully customized by implementing JavaScript or Cascading Style Sheets, or by editing the PHP files directly. Before using these methods, note that:
 * JavaScript is fragile: it will not work for users with JavaScript disabled, and scripts frequently fail in different browsers or skins.
 * Editing the PHP files can easily cause unexpected errors, and your changes will be lost in the next update unless you manually change the new files.

Force UI-messages to follow content
Some pages should sometimes follow the content language, especially for multilingual sites. This can be controlled with the setting. Each message overridden in this way must be explicitly given, for example to let the sidebar link to versions given by the content language for the main page and the portal page add the following to


 * code

Add or remove toolbox sections (JavaScript)
The toolbox appears on the left under MediaWiki:Sidebar. The toolbox is a dynamic element requiring programmatic methods such as skin extensions, PHP (see  and creating a new skin) or JavaScript.

The JavaScript solution uses User:{username}/common.js / MediaWiki:Common.js, available for MediaWiki 1.9+.


 * Entire MediaWiki website: copy the script below into MediaWiki:Common.js
 * One specific user: copy the script below into Special:MyPage/common.js (or the JS page for the user's current skin, such as Special:MyPage/monobook.js).

Now simply configure which link should appear in which section. You also can remove some links if you want to.


 * code


 * Usage
 * has to be customized for adding or removing links in specific sections:



 If you want to restrict the modification of the links to a specific user group (e.g. bureaucrat), change: to
 * Restricting modifications to specific usergroups

For restricting the modifications to IPs instead of a specific user group, use

Add or remove toolbox sections (PHP)
You can add in your file LocalSettings.php the hook described on this page. With this, you can modify via MediaWiki:Sidebar the links in the toolbox panel (remove some links, change their name) and add custom links (e.g. add the "Recent changes" link there instead of the navigation panel.

Make expanding/collapsing sidebar for all users (Monobook skin only)
If you use the Monobook skin and don't want to miss the expandable menu bar from e.g. Vector skin, paste the following code into MediaWiki:Monobook.js of your wiki.

Sidebar width in Monobook skin (CSS)
You can change the width of your sidebar by adding the following CSS rules to your MediaWiki:Monobook.css ; note that this is an article, not a file. This changes the width to 15em, the actions position and portlet width should be an em or so less, so I've set them to 14em in this example.

Change sidebar content when logged in (PHP)
Install and configure the extension.

Parser functions in sidebar
Although it is not exactly recommended, the sidebar does support parser functions (such as ParserFunctions), provided the  is outside the parser function, and the parser function does not span multiple lines. For example:
 * Heading

works. However the following would not work since the parser function spans multiple lines:
 * Heading

Changes not showing up
MediaWiki aggressively caches content if possible, which often causes the navigation bar to persist after changes. Purging the cache of affected pages should correct the situation. To perform a mass-purge of all caches at once, touch the  file or truncate the   table in your database (you may have to do both).

You also need to have set to. Also, if your links don't have a  in them, they will not show up because of this line of code in Skin.php:

If you are a user or average wiki admin, you will not be able to do the advanced stuff above to get changes to show up. If purging does not work either, you can sometimes still see CSS changes right away in preview (especially when changing your personal CSS). For example; changing the sidebar width, padding, or margins. Changes can take awhile to show up after saving though. If nothing shows up after awhile you may need to contact the overall wiki, or wiki farm, sysop.

Lowercase link labels
If your links are not being capitalized as intended, try adding spaces around the bar character; for example: ** http://www.example.com/download.php?file=44555 | Download

Sections disappear or show unexpected content
If a section does not display or displays unexpected content, check that the header text isn't the name of an interface message by searching Special:AllMessages. If it is, use a different header text, or create a new interface message and use it.

For example, if you want to use "Sidebar" as header text, create the interface message "MediaWiki:Sidebar-header" containing only "Sidebar". Then, use  as header.

Sections are not displayed if there are no links of the form  (e.g. when the target was forgotten).

Broken links after updating Special:Version
This will happen e.g., each time there are newer translations for your site language's sidebar items. One could add new redirect pages each time, but a better solution would be to use one's own sidebar item names instead of trying to keep track of the current MediaWiki translations.
