Taxonomy/Views related questions: custom "menu" and count of descendant products
Hey all. I've come across a couple snags that I'm hoping for some help with.
First of all, I'm able to get a count of all children nodes of a term by using taxonomy_get_children() (http://api.drupal.org/api/function/taxonomy_get_children/5), but is there a library function (or some other means) to get a count of all descendants of a term? I have a multi-level taxonomy hierarchy, and, in general, all nodes are tagged with a single term at the deepest level.
Secondly, I have a custom, argument-based view that I've created (products/$arg) that displays all nodes tagged with a term equal to the argument. In one of my block areas, I have a block that outputs all terms in this particular vocabulary and a link to the appropriate page:
<?php
// The ID of the taxonomy vocabulary for which you'd like to create a nested list
$vid = 1;
$depth = 0;
$num_at_depth = 0;
$tree = taxonomy_get_tree($vid);
print "<ul class=\"menu\">\n<li>";
foreach ($tree as $term) {
$diffdepth=0;
if ($term->depth > $depth) {
print "\n<ul>\n<li>";
$depth = $term->depth;
$num_at_depth = 0;
}
if ($term->depth < $depth) {
$diffdepth= $depth -$term->depth;
while ($diffdepth > 0){
print "</li>\n</ul>\n";
$diffdepth -- ;
}
$depth = $term->depth;
}
if (($term->depth == $depth) && ($num_at_depth > 0)) {
print "</li>\n<li>";
}
$termPath = strtolower($term->name);
$termPath = str_replace(" ", "-", $termPath);
print l($term->name, 'products/' . $termPath);
$num_at_depth ++;
}
print "</li>\n</ul>\n";
?>Is there any way to get the block to "interact" with the views pages that are created? That is, if someone visits products/term-A (where Term A is a child of Term 1), the menu currently looks like this and does not change for all views:
-Term 1
--Term A
--Term B
--Term C
-Term 2
--Term D
--Term E
-Term 3
--Term F
I'd like the menu to look something like this when someone was on products/term-A, products/term-B, or products/term-1:
-Term 1
--Term A
--Term B
-Term 2
-Term 3
I'm stumped because there isn't really a strong relationship between the view itself and the menu, and I'm not quite sure where to start.
Thoughts?

Maybe I'm not understanding
Maybe I'm not understanding what you're asking for, but isn't this what the http://drupal.org/project/tinytax module does?

No; each term links to
No; each term links to "products/", not the default term pages provided by taxonomy. No need for AJAX in this case, either, unless there's a technical reason that I'm overlooking.
