Displaying sub categories

    Hey!

    I’ve a problem with displaying the sub categories of posts on archive page, and couldn’t find a definitive answer on forums and other WP related websites. Here is the problem:
    Here is a rough view of my category system

    • Category A
    • Sub Category A-1
    • Sub Category A-2
    • Sub Category A-3
    • Category B
    • Sub Category B-1
    • Sub Category B-2

    and so on.

    For instance, a visitor is viewing the archive page of “Category A” and all the latest posts are listed in a chronological order. The posts here also have sub categories. Some of them have one sub category, let’s say “Sub Category A-1”, whereas others have more than one sub category, e.g. “Sub Category A-2” and “Sub Category A-3”.

    What I want to do display these sub categories without linking before the title of post. Sometimes I need to display only one sub category but there are some instances where I have to display all the sub categories.

    Does anyone have an idea how I could accomplish this?

    Thanks in advance.

    <?php $cats = get_the_category($post->ID);
$sep = '';
foreach( $cats as $cat ) {
  $subcats = get_categories('child_of='.$cat->term_id);
  if($subcats) {
    foreach( $subcats as $subcat )
      {   echo $sep . $subcat->name; $sep = ', '; }
  }
}
?>

    the above will show all subcategories of all the post’s categories at all times.

    Sometimes I need to display only one sub category but there are some instances where I have to display all the sub categories.

    how is this defined?

    Hey alchymyth,

    Thanks for response and code hint. However this outputs all the sub categories.

    Now I’ve slightly changed my approach. Instead of what I stated earlier, I want to output only one sub category. It’s hard to explain without visual that’s why here is the link of site I’m working on.

    Here, all 4 top categories have the same sub categories. And every post has one of these sub categories. For instance, if a post has “Teknik” as top category, it will for sure have one of the four following sub categories of Teknik: Nyheter, Tester, Guides, Features. In addition to that, it could also have one or two more sub categories of Teknik. So posts would look like this:

    Post A: Teknik, Nyheter
    Post B: Teknik, Tester, Dator
    Post C: Teknik, Guider, Mobilt, Mjukvara

    etc…

    So what I want to do now is to display only one of these four main categories. The same goes for other top categories: Musik, Film och Spel.

    Is there any chance you have a hint for this as well?

    Btw, I know it’s kinda off the topic but I’ll ask. Do you know how I could make use of WordPress trac? For instance can I use the code listed in this file in my theme?

    Regards.
