Extension:Display Title/pl

The Display Title extension allows a page's display title to be used as the default link text in links to the page - both links from other pages as well as self-links on the page. Display Title also uses the display title of a page as part of the title of its talk page. It optionally displays the original page title as a subtitle on the page. And, it provides a parser function to query a page's display title.

This extension builds on functionality in MediaWiki core that supports setting a page's display title using the  magic word. Placing   on a page stores the value of the display title (My Display Title in this case) in the displaytitle page property of the MediaWiki page_props table and, if configured appropriately, displays that value on the page as the title in the title bar. The Display Title extension queries the displaytitle value in the page_props table to provide its features.

Parametry konfiguracyjne
While not strictly necessary for the functioning of Display Title, in order to allow the  magic word to function as expected, set the following MediaWiki core configuration variables:

Display title on edit pages and edit links
In order for the Display Title to be used on edit pages and links to them, edit the following system messages on your wiki (substituting the wiki's local language where appropriate):

And if you also use Page Forms.

Linking
The behavior of the Display Title extension for different types of links is summarized below. The table shows what the link text will be for different situations. In the table, A represents a page title and a represents the page title with the first character of the page name (i.e. the part after the Namespace: if there is a namespace) in lower case. Note that if a page is a redirect (i.e. Page A in the "Page A Redirects to Page B" columns below) and has a display title set, that display title will be ignored by this extension.

parser function
The  parser function gets the display title of the page provided. For example:

will show the displaytitle of page. To get the display title of the current page, use:

Lua/Scribunto support
Two Lua (see ) functions exist for getting and setting a page's display title:  and. To use them, you could create a page  containing the following:

You could then use  on a page to set the page's display title to My Display Title, and you could use   to get the display title of page My Page.

Redirects
For redirect pages, if the target page has a display title, it will be used as the display title of the redirect page.

Note that this has two implications that may be unexpected the first time a user sees them. When a page with a display title is moved leaving a redirect, on the page indicating that the move was a success the link text will be the same for both the source and target pages. And, on the Special:WhatLinksHere page for a page with a display title that is the target of a redirect, the link text of the redirect page will be the display title of the target page.

A single level of redirect will be followed.

History
The functionality in this extension evolved as part of the Semantic Title extension. Special thanks go to Van de Bugger, the author of version 1.0 of Semantic Title.

Display Title relies only on functionality in MediaWiki core; it does not depend on any other extension. The functionality in Display Title has been removed from Semantic Title, which now retains solely the functionality to set a page's display title from a Semantic MediaWiki property or Cargo field. However, it is recommended that a page's display title be set using  rather than the functionality in Semantic Title. Semantic Title is being maintained for backward compatibility.
