User:Hoggwild5/ExtraSidebar

The function below can be copied and pasted into the skins.php file you wish to modify, after the following:

       function initPage( &$out ) {
		SkinTemplate::initPage( $out );
		$this->skinname  = 'monobook';
		$this->stylename = 'monobook';
		$this->template  = 'MonoBookTemplate';
	}

Make sure the function is part of the first class in the skins file, the one that extends SkinTemplate.

Code

	function buildSidebar() {
		global $wgLang, $wgContLang, $wgUser;

		$fname = 'SkinTemplate::buildSidebar';

		wfProfileIn( $fname );


		$bar = array();
    	$lines = explode( "\n", wfMsgForContent( 'sidebar' ) );
        if($wgUser->isLoggedIn()){
            $lines2 = explode( "\n", wfMsgForContent( 'sidebar-internal' ) );
            $lines = array_merge($lines, $lines2);
        }
		$heading = '';
		foreach ($lines as $line) {
			if (strpos($line, '*') !== 0)
				continue;
			if (strpos($line, '**') !== 0) {
				$line = trim($line, '* ');
				$heading = $line;
			} else {
				if (strpos($line, '|') !== false) { // sanity check
					$line = explode( '|' , trim($line, '* '), 2 );
					$link = wfMsgForContent( $line[0] );
					if ($link == '-')
						continue;
					if (wfEmptyMsg($line[1], $text = wfMsg($line[1])))
						$text = $line[1];
					if (wfEmptyMsg($line[0], $link))
						$link = $line[0];

					if ( preg_match( '/^(?:' . wfUrlProtocols() . ')/', $link ) ) {
						$href = $link;
					} else {
						$title = Title::newFromText( $link );
						if ( $title ) {
							$title = $title->fixSpecialName();
							$href = $title->getLocalURL();
						} else {
							$href = 'INVALID-TITLE';
						}
					}

					$bar[$heading][] = array(
						'text' => $text,
						'href' => $href,
						'id' => 'n-' . strtr($line[1], ' ', '-'),
						'active' => false
					);
				} else { continue; }
			}
		}
		wfProfileOut( $fname );
		return $bar;
	}

Notes

• Because the sidebar changes depending on the logged in status of the user, caching for the sidebar has to be disabled. This is a small performance hit, and one that should not be noticable on any but the most active sites. If you have been using $wgEnableSidebarCache or $wgSidebarCacheExpiry, these settings will no longer function for any skin utilizing this sidebar.
