Hi- I'm developing a news site and am trying to figure out how to pull the latest stories out of a nested hierarchy. For example the hierarchy might look something like:
A
-1
--a
--b
--c
-2
--d
--e
---
---3
--f
---4
----g
----h
----i etc. what kind of syntax do i need to walk the hierarchy and grab the latest 5 stories? Is there a good place to look for code snipets? I've checked these forums and the wiki, but there isn't anything that i can find that seems to do it. any one done this before? arthur

Nothing special really (no hierarchy walk necessary), its all in the fetch function parameters: pay special attention to the depth: set it to a large number or choose 0 (this appears to be unlimited depth) and then sort by published (ascending or descending -- try it out) should do the trick. I used something similar for the forum enhancement. See http://ez.no/developer/ez_publish_3/documentation/ez_publish_3/howtos/how_to_fetch_function_parameters_and_examples Paul

thanks for the fast reply
here's the code snipit that i am using to just traverse the whole list:
{let test=fetch( 'content', 'list', hash(parent_node_id, 159, "sort_by", array("name", true()), "depth", 0)) }
{section name=Child loop=$test}
{node_view_gui view=line content_node=$Child:item}<br>
{/section} which does work. now i just gotta figure out how to only return the most recent 5 :)

so this is the code that i used to grab the 5 most recent stories. Has there been any thought to developing a code library for snipts of code like this so that newbies (like myself) can easily grab commonly need functions? I think it would be super helpful.
{* change node id 159 to match your node *}
{let test=fetch( 'content', 'list', hash(parent_node_id, 159, class_filter_type, "include", class_filter_array, array(2), "sort_by", array("name", true()), "depth", 0)) }
{section name=Child loop=$test max=5}
{node_view_gui view=line content_node=$Child:item}
<br>
{/section}

The template system is very powerful; only by providing such real world examples the true power is revealed. Paul

I think this way is more nice:
fetch(content,list,hash(parent_node_id,16,limit,5,sort_by,array(published,false()),class_filter_type,include,class_filter_array,array(2))) you don't need to limit in loop since you are able to limit in fetch function. Another thing you need to sort by published attribute, not name.

Does the last one work with v3.0.2?? I have 3.0.2 on my laptop which works.. but my hosted on v3.0.1 .. it does not .. for some strange reason .. perhaps a typo, but I have redone this several times now already!
Kindest,
