How can I get parent category ID in single page template, outside of loop?
$category = get_the_category();
echo $category[0]->term_id;
The code isn't working outside loop correctly.

This should work on single posts, see this answer. What happens on your site? Are there other queries on that page? – fuxia♦ Jun 5 '13 at 5:32

I'm solved, by using:
$category[0]->parent
Thanks anyway.
