The request is ?cat=2, and this code does the trick.
$cat_shown = array();
foreach ($category_cache as $cat_array) {
foreach ($cat_array as $the_category) {
$the_ID = $the_category->cat_ID;
if (in_array($the_ID, $cat_shown))
continue;
$cat_shown[] = $the_ID;
echo $the_category->cat_name;
echo "<br>\n";
}
}
And use $posts to get all posts from cat=2 and sub-categories.

Thanks, but I’m developing a theme and would like to incorporate this feature as a standard.
Is this really that hard to program using a WP_Query or The Loop (in some way)?
If I click a category (ie, ?cat=3), how do I “get” that var? Is the only way to get it through $_GET? And after that, constructing a query that gives me all subcategories of that one, and for each of those, give me all posts.
Does anyone have any ideas about doing that?
Mike
