How to get parent_id of category in categories.php?

[pietg]

At the moment I am trying to restyle categories.php a little bit.

Part of it is the following code:

Code: [Select]

$categories2 = get_categories($cat_id);
$site_template->register_vars("categories2", $categories2);
unset($categories2);

I am searching for a way to fill the $cat_id in this code with the value of the cat_parent_id of the category

Example:
cat_id 1 = category A: Soccer Game  
cat_id 2 = subcategorie 1: Team 1 (cat_parent_id 1)  
cat_id 3 = subcategorie 2: Team 2 (cat_parent_id 1)
cat_id 4 = subcategorie 3: Team 3 (cat_parent_id 1)

So if people are in the cat_id 2, I would like to fill $cat_id with value "1".

Does somebody know how to do this?

kind regards,
Piet

if u want find out parent category ID, use this:

Code: [Select]

$cat_cache[$cat_id]['cat_parent_id']
if u also need NAME of parent category, use this:

Code: [Select]

$cat_cache[$cat_cache[$cat_id]['cat_parent_id']]['cat_name']

Thanks you very much.

It worked together with some extra modification in function.php.

If somebody now browses to a subcategory he/she can see the "above" categories in the left colum.

Thanks again.
