Hello,
I am using Node Hierarchy extensively on this one web site, to create sections and for the main navigation. The structure looks something like this:
Product A <<< product logo attached here
- Product Page A.1 <<< needs to appear here
- Product Page A.2
+ Some Page A.2.a <<< and here
+ Some Page A.2.b
- Product Page A.3
Product B
...The product page has a couple of images (as cck fields) that need to be be visible on the child pages as well. Basically, I need to find the closest parent of type `product` and use its `nid` in a view.
I was thinking there may be a way to do this with Views and arguments, but I don't have the skills to make that work. I also noticed this #256696: Top-most parent as argument in view, but the instructions are enough to put me on the right track. I even polished the code a bit to make it check for the `product` node type, but I don't know how to use this with the Views.
<?php
function phptemplate_get_oldest_ancestor($nid) {
$n = node_load($nid);
if ($n->type == 'product') = return $n;
$node_parent = $n->parent;
if($n && $n->parent) {
$n = theme('get_oldest_ancestor', $n->parent);
}
}
?>If anyone could help, I would really appreciate it. Thanks.

So just for future reference, the way we solved this problem:
1) Modified the code a bit and instead of using a theming function, we put that in a module like that:
<?php
function custom_get_oldest_ancestor($nid) {
$n = node_load($nid);
if ($n->type == 'product') {
return $n;
}
elseif($n && $n->parent) {
$n = custom_get_oldest_ancestor($n->parent);
}
return $n;
}
?>
2) Built a views block to display the fields we need (2 image fields and a title) and added an argument Node: ID
3) Created a PHP block where we call our function and embed the view with the argument like that:
<?php$arg = custom_get_oldest_ancestor(arg(1));
print views_embed_view('product_headers', 'block_2', $arg->nid);
?>
product_headers is the name of the view, block_2 is the ID of the views block within the view. See http://drupalcontrib.org/api/function/views_embed_view for more information on views_embed_view.
