Extension talk:BackwardNavigation

Fix for 1.11.0 +

Every function must return something so just add TRUE to any Return ; as so in BackwardNavigation_body.php :

        if (!is_object($wgMessageCache)) return true;
        if ( $messagesLoaded ) return true;

Customizing your skins

To get this work, you must have your own template file into the skins/ directory.

Quick-creation of a new template

Copy-paste MonoBook.php into Foo.php
Copy-paste monobook/ sub-directory into foo/
Into MonoBook.php, replace all MonoBook occurences with Foo
In your LocalSettings.php configuration file, you can change $wgDefaultSkin from 'monobook' to 'foo' to get this by default

Then you can customize your skin to make this extension work :

Replace something looking like this :

<li id="t-whatlinkshere"><a href="<?php
echo htmlspecialchars($this->data['nav_urls']['whatlinkshere']['href'])
?>"<?php echo $skin->tooltipAndAccesskey('t-whatlinkshere') ?>><?php $this->msg('whatlinkshere') ?></a></li>

with this :

<li id="t-whatlinkshere"><?php
global $wgTitle;
$backNav_controller=new BackwardNavigation();
echo $backNav_controller->executeBackwardNavigation($wgTitle->getArticleID())
?></li>

And thats it

Customizing the css

Add the customization lines at the end of skins/foo/main.css :

.popup{
	text-decoration: underline;
	position: relative;
}
		
.popup:hover{
	background-color: transparent;
	text-decoration: none;
}
			
div.cadre_popup{
	visibility: hidden;
	position: absolute;
	z-index: 10;
	text-decoration: none;
	top: 0px;
	left: 0px;
	background-color: white;
	color: black;
	border-collapse: collapse;
	border: 1px solid #aaa;
	padding: 0 .8em .3em .5em;
}

#referer_popup {
	//top: #popupanchor.top;
	z-index: 100;
}
		
span:hover.popup div.cadre_popup{
	top: 0px;
	left: 0px;
	visibility: visible;
}
		
span .popup div:hover.cadre_popup{
	visibility: visible;
}

a.popup {
	text-decoration: none;
}
span.popup {
	text-decoration: none;
}

Here we are ;-).

Multi-namespaces use

If you've got problems using BackwardNavigation with multiple-namespaces, simply change this line in BackwardNavigation_body.php :

change this :

$SQL="SELECT pc.page_id referer FROM ! p INNER JOIN ! pl ON (p.page_title=pl.pl_title) INNER JOIN ! pc ON (pl.pl_from=pc.page_id) WHERE p.page_id=? and pc.page_namespace=0 order by referer";

with this :

$SQL="SELECT pc.page_id referer FROM ! p INNER JOIN ! pl ON (p.page_title=pl.pl_title) INNER JOIN ! pc ON (pl.pl_from=pc.page_id) WHERE p.page_id=? order by referer";

(look : I've just removed "and pc.page_namespace=0")
