>>//NOT Included in any Wikka version yet//{{lastedit}}
==What==
~- Finds pages within the current page name and builds a menu with it.
~- If you add sub-pages by adding a string to the parent page name (e.g. ""OnegWRTree"" is the sub-page ""Tree"" of the parent-page ""OnegWR"") you can loop trough the string and check if this string within the page name is a page on it's own...
~~ e.g. HomePage > OnegWR > OnegWRTree

==Use==
~- Include on the page where you would like to include this little menu the string:
~~""{{tree}}""

==Installation==
~- Save the code below as ##action/tree.php## 
~- Give it the same file permissions as the other php files in that directory.
~- Note: function ""ExistsPage"" is included in 1.1.6.0

==Code==
%%(php)
<?php
// Display a 'tree' of parent-pages by OnegWR
// e.g. OnegWR > OnegWRactions > OnegWRactionsTree
$treelink=$this->Link($this->config["root_page"]);
$treepage="";
$max = strlen($this->tag);
for($i=0;$i<$max;$i++){
	    $treepage .= $this->tag{$i};
	    if( $this->ExistsPage($treepage) ){
	            $treelink .= " &gt; ";
	            $treelink .= $this->Link($treepage);
	    }
}
print $treelink;
