What can this extension do?
This extension proposes a popup interface to "what links here".
This extension overrides the behavior of the "What links here" link in the sidebar (by default found in the toolbox area).
- If the page is not referred to by any other, the sidebar "What links here" does nothing.
- If only one page is linked to the current page, “What links here” is a link to that page
- If several pages are linked to the current page, bringing the mouse on “What links here” posts a popup containing the list of these pages.
- If there are too many pages, "What links here" behaves as usual (in plain vanilla MediaWiki) and displays a special page listing all pages referring to this page, i.e. it's a link to
We very highly advise you to proceed to an installation on a test server before modifying your production server. A backup is always a good idea before making modifications.
Copy the extension files

If you use the MultiLanguageManager extension you have to add BackwardNavigation after MultiLanguageManager.
Integration in your template
To display the referer selection, you have to modify your template to add the following code where you wish to see appearing the selection referer element :
<?php global $wgTitle; $backNav_controller=new BackwardNavigation(); echo $backNav_controller->executeBackwardNavigation($wgTitle->getArticleID()); ?>
You also have to change your CSS files, cf Customize the CSS.
BackwardNavigation has been designed to adapt to different skins. The graphic functions are isolated in the file BackwardNavigation_template.php containing the class from the same name. It contains the various method used to create the view.
You must not modify it. If you alter this file, the change could touch all the skins. Indeed the module uses this class only if it can't find specific class for your skin. It is the generic class derived by all the module skin
Create a new skin
In the extensions/BackwardNavigation/skins directory, duplicate the Default.php file and name the copy of the name of your skin (the same file name as the .php of the directory skins of the wiki).
By defect this class contains only the manufacturer, but you can overload all the methods of your choice. An example is given with the Art122-5.php file that modify the method of the popup to correspond to the style of the wiki.
Customize the CSS
You also have the possibility of personalizing the CSS. The name of the various classes can be modified by overloading the variables $class_ of the class BackwardNavigation_template , you can find an exemple of CSS configuration at the beginning of this file.
- class_referer_disabled = referer_disabled : no referer
- class_referer_activated = referer_activated : only one referer
- class_popup = popup : the link used to display the popup
- class_cadre_popup = cadre_popup : the popup
