Re: Multi-level menu with Modified Preorder Tree Traversal

Hi Sam,
I don't have time to make test at this moment, and sincerely i think recursion is the best method to make this work.
I can tell you of a solution i found time ago with cake 1.0 in one of my application.
The base of the logic is in the query i wrote (the query is simplified i write here only the significant fields):

SELECT node.lft, node.rgt, node.id, node.parent_id, (COUNT(parent.parent_id) - 1) AS depth,
       node.description, node.link FROM menu AS node, menu AS parent
       WHERE node.lft BETWEEN parent.lft AND parent.rgt;

this query return a flat list with a depth field that is the level of indentantion of the item (node).
I think something like this can do the work:

$depth = $items['Node'][0]['depth'];
echo '<ul>';
foreach( $items as $k => $item ) {

}

This is a great article, but doesn't have a lot to do with CakePHP. It certainly spells it out clearly though, and the examples are in PHP.

Hi Marco, thanks 4 your answer too! I realy do appreciate those great scripts you're sending to me. But right now, I still got the problem that I can't write the essence of a multi-level menu (without recursion) on my own ;)

Perhaps, you can tell me if / how I can cross my tree-based database table and output it in a realy simple <ul><li> list? No active class of whatever, but the real essence would help me a lot! :)
