I tried to edit the skin, but the problem is that I cannot refer to a navigation-layout-page I made in the mediawiki-namespace (because I had to set $wgUseDatabaseMessages=false). I think the solutions lies in referring to a navigation-layout-page that is not in the mediawiki-namespace, but I don't know how to do that. The explanation given on http://meta.wikimedia.org/wiki/Layout_customization#How_do_I_add_an_editabl… only point out a solution in case $wgUseDatabaseMessages=true.... 2006/3/28, Rob Church <robchur(a)gmail.com>om>:

Thanks a lot for the help! The hierarchical navigation bar is working now ;-) While playing around with the menu, I encountered some strange behavior though: 1. Whatever I put before the sublevel, is placed automatically above the navigationbox. For example: 'sidebar' => ' * [[Mainpage|Main Page]] * [[Special:Recentchanges|Recent Changes]] * [[Current_events| News]] * [[Help|Help]] * Cases ** [[Technicalcase|Tcase]] ** [[Businesscase|Bcase]] ', MediaWiki puts then the word "Cases" above the navigationbox. I have tried to put "*navigation" right above "* [[Mainpage|Main Page]] " but unfortunately this does not help. MediaWiki keeps putting the word that is placed right above the sublevel above the box. Why is this done automatically? How could i possibly change this? 2. I wanted to make a second box beneith the navigation box and therefore i had put <?php $this->msgWiki( 'sidebar' ) ?> <?php $this->msgWiki( 'casebar' ) ?> in monobook.php with 'casebar' => ' * Cases ** [[Technicalcase|Tcase]] ** [[Businesscase|Bcase]] ', Unfortunately, MediaWiki joins the two bars together into one box. Is it possible to create two separate boxes? I could separate boxes before (when i did not apply the hack<http://meta.wikimedia.org/wiki/Layout_customization#How_do_I_add_an…)F>), by just putting "*" before the word that had to appear above the box. I don't see how it is possible to figure that out while applying the hack... Thanks again for any help! Birger. 2006/3/28, wilinckx < wilinckx(a)willempen.org&gt;gt;:

Thanks! Everthing is displayed and working perfectly now ;-) One thing I do not clearly see is the fact that I had to change sidebar into casebar in includes/skin.php: function buildSidebar() { $fname = 'SkinTemplate::buildSidebar'; wfProfileIn( $fname ); $bar = array(); $lines = explode( "\n", wfMsgForContent( 'casebar' ) ); foreach ($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 (wfNoMsg($line[1], $text = wfMsg($line[1]))) $text = $line[1]; if (wfNoMsg($line[0], $link)) $link = $line[0]; $bar[$heading][] = array( 'text' => $text, 'href' => $this->makeInternalOrExternalUrl( $link ), 'id' => 'n-' . strtr($line[1], ' ', '-'), ); } else { continue; } } } I had to do this, apparently since no boxes could be displayed because sidebar does not contain sublevels (it only contains *items and no **items, while casebar does have **items), but I do not understand quite well why exactly I had to change this. I guess it has something to do with f (strpos($line, '**') !== 0) { $line = trim($line, '* '); $heading = $line; but i'm not sure. In any case, thanks a lot for the help you gave me! I'm really happy it works now :-) Birger. 2006/3/29, wilinckx &lt;wilinckx(a)willempen.org&gt;rg>:
