Hello.
I am modifiing my theme. When only showing posts that belong to a category (and subcategories of that) (using archive.php), I need to learn the category id which is shown.
For example I have a category names "Computer". Its id is 12.
I am on a page http://site.com/categories/computer that shows all posts which are categorized in Computer or one of its sub categories. The output is generated in categories.php (I don't want to use category-slug.php structure) In categories.php how can i learn Computer's id, 12?
A post can be in several categories, so you may have a hard time choosing the correct one from an array, but here is how to get the array:
wp_get_post_categories() will return an array of category ids for the current post. I think the array is in order of category name.

Hello. I don't want to learn a post's categories. I am talking about a category filter.
I studied WP source code, and found something like this to get category id.
$cat = intval(get_query_var('cat'));
if (!empty($cat) && !(strtoupper($cat) == 'ALL'))
Modified it, for self use and I am happy now. :)
