Building a tree layout

[felic]

Hi everyone!

I have parent page (and template) dates with numerous child pages for single event dates. Beside the content related fields each child page contains two fields which are added (for now) just for sorting purposes (item_sorting_month, item_sorting_year). Getting those child pages and output them in a straight foreach loop is simple:

$current_date = date("d.m.Y");
$items = $page->children("item_date>=$current_date, sort=item_sorting_year, sort=item_sorting_month");

foreach($items as $item) { .. }

This gives me a well sorted flat output like this:

- item

- item

But what i like to achieve (and doesn't get it right) is this:

- Year

-- Month

--- item

-- Month

--- item

- Year

-- Month

--- item

-- Month

--- item

Additionally i like to establish a anchor link navigation to all available month, e.g. Feb.2016, Jul.2016, Jan.2017 a.s.o. because the list might be a large one.

I spent more than a day with several trail/error (separate $page->find(...), nested foreach loops etc.) at least. But all leads to nothing :-/

Maybe some of you have some hints where to look at, e.g. how to achieve this. I hope my description is precise enough. Otherwise, please don't hesitate to ask.

Cheers and thx in advance

I guess you are trying to build something like this. It is an example blog profile for PW built by ryan. Here is the source code for that page - a place to copy-and-paste from or get inspired with. If it does not help, feel free to write back.

By the way, you don't need those extra fields just for sorting purpose as you will see in the code provided. One date field holds all the data needed to make that tree.

Ivan, thanks for the link(s)! Yes, ryan's blog/archives templates looks promising how to get my desired render structure . I'll get my hands on the code tomorrow and hope i am able to adapt this for my needs.
