You have to create extension and in hook
fn_generate_navlinks_end
inject
$mylink = '<li id="navtutorial"'.((FORUM_PAGE == 'tutorial') ? ' class="isactive"' : '').'><a href="tutorial.php">Tutorial</a></li>';
array_splice( $links, 5, 0, $mylink );
Where:
$mylink = '<li id="navtutorial"'.((FORUM_PAGE == 'tutorial') ? ' class="isactive"' : '').'><a href="tutorial.php">Tutorial</a></li>';
navtutorial - should be remembered if you wish to style this element later
tutorial - is FORUM_PAGE which you've declared in your custom page.
tutorial.php - is custom page address.
and
array_splice( $links, 5, 0, $mylink );
5 - link position
Note that the proper and more valid way is to edit /include/url/your-link-scheme/forum_urls.php
( eg. I'm editing /include/url/Default/forum_urls.php )
and add at the end another value
'tutorial' => 'tutorial.php'
(watch out for commas! )
Plus create language array in your extension, so the link could look like this:
$mylink = '<li id="navtutorial"'.((FORUM_PAGE == 'tutorial') ? ' class="isactive"' : '').'><a href="'.forum_link($forum_url['tutorial']).'">'.$lang_array['mylink'].'</a></li>';
edit.
You're playing very well with title, this will also affect lastcrumb title.
If any of my dropbox link fails with 404 error, change dl.dropbox.com/u/56038890/punbb/*.zip in address to 82283017.
Currently working on rPlus - responsive theme for developers to create their own themes basing on this one.
