How to show beneath posts the full category path?

Question

My portal has the following category structure: CategoryLevel1=>CategoryLevel2=>CategoryLevel3=>CategoryLevel4

I assign posts to CategoryLevel4 but I want to show the full category path beneath each post. Each node should be clickable.

Thanks.

Answer 1

Assuming your categories are in a parent=>child hierarchy as listed(ie category4 is a child of category 3, etc) then this should give you what you're after:

the_category("»", "multiple", $post->ID);
