Show all posts in category

Question

I am trying to show all posts in each category. I've been searching around and it seems I need to have either the category slug or term_id to do so, like the code below.

<?php query_posts('category_name=MyCategory&showposts=9999'); ?>

I'm currently editing the archive.php how to get the slug name?

Thanks.

Answer 1

to get the category slug of the category archive:

$cat_slug = get_category(get_query_var('cat'))->slug;

alternatively, to get the category ID of the category archive:

$cat_id = get_query_var('cat');
