How to make breadcrumbs?

Question

1. I want to make breadcrumbs. For example: Home / * title question *. How can I do this?

2. And how can I make writing category, before title to the question? For example: WEB / How do I edit. Css? or Health / How to become a champion?

Sorry for bad English.

Thank you.

1. You'd need an advanced HTML theme which uses PHP to output the appropriate HTML based on the current page. You could use $this->template and/or $this->request in your qa-theme.php to see what kind of page you're viewing.

2. This is easier. Modify qa_post_html_fields(...) in qa-app-format.php as follows:

if (isset($category))
    $fields['where']=qa_lang_html_sub_split('main/in_category_x', qa_category_html($category));

... to ...

if (isset($category)) {
    $fields['where']=qa_lang_html_sub_split('main/in_category_x', qa_category_html($category));
    $fields['title']=qa_html($category['title']).': '.@$fields['title'];
}

I am interested in this future(No.1), too. And SiteMap.
I seem not to be able to dismantle a pass well.
Below requestString($this->request) is anxious.

1.1 Question
  Path of question List: questions, activity, unanswered ...
  Path of specific question: 99/q-title
　My perplexity: "99" and "q-title" is not the relations of parent and child.

1.2 User(s)
  Path of user List: users
  Path of specific user(ex:abc): user/abc
  My perplexity: Only "user" is "page not found". "users/abc" ?

1.3 Tag(s)
  Path of tag list: tags
  Path of specific tag(ex:abc): tag/abc
  My perplexity: Only "tag" is "page not found". "tags/abc" ?

1.4 Relation of questions/activity/unanswered/.../Admin ... and each question

I can not to find this code in qa_post_html_fields(...) in qa-app-format.php. It might be different in the current version. If true, do you know how to show breadcrumbs on version 1.5?

Yes, this was changed when hierarchical categories were introduced. Look for $fields['where'] to see the expanded version of that code - you can now get the category name from qa_html($post['categoryname']) instead of qa_html($category['title'])
