Nedjo: Breadcrumbs in Drupal lead up to, but do not include, the current page. Assume a taxonomy like this:
Food (vocabulary id 2) grains (root term, id 1) wheat (second-level term, id 2) rice (second-level term, id 3) vegetables (root term, id 4) potatoes (second-level term, id 5) onions (second-level term, id 6)
When browsing the term 'rice', I assume the breadcrumb should be:
When browsing a node assigned to rice, the breadcrumb should be:
We should probably look at the taxonomy_breadcrumb module for comparison.
Frederic: I'm a bit reluctant on this. One the one hand, ISTR that breadcrumbs in drupal are supposed to as you describe. OTOH, there's a snippet to include the page title, which means it is felt as needed and, maybe more importantly, Steve Krug, in its oft-quoted “Don't make me think” book about web usability, insists on including and even boldfacing the last item in the breadcrumbs, and I think this advice is as good as most of the book (I hear even Dries has it). To illustrate this example I'd say that browsing “rice” should give
and show a page related to the terms rice, typically the list of nodes matching the term. while browsing a node assigned to rice, say Carnaroli, the breadcrumb should be:
… which happens to be how drupal works from the home page, which by default displays a node list matching a criterium (published + promoted), from which each node is one level deeper as a detail page. Same with these taxonomy contexts: term page lists nodes, putting the node list in its parental context, and node pages show the nodes, in their parental context.
to include automatic permalinks within the same logic
