How to List All Subcategories in WordPress

Snippets by IsItWP

Are you looking for a way to display a list of only subcategories? While there’s probably a plugin for this, we have created a quick code snippet that you can use to list all subcategories in WordPress.

Instructions:

All you have to do is add this code to your theme’s index.php file or in a site-specific plugin:

    $echo = '<ul>' . "\n";
    $childcats = get_categories('child_of=' . $cat . '&hide_empty=1');

    foreach ($childcats as $childcat) {
        if (1 == $childcat->category_parent) {
            $echo .= "\t" . '<li><a href="' . get_category_link($childcat->cat_ID).'" title="' . $childcat->category_description . '">';
            $echo .= $childcat->cat_name . '</a>';
            $echo .= '</li>' . "\n";
            }
    }
    $echo .= '</ul>' . "\n";
    echo $echo;

  1. I am so good at messing out so here is a few questions/comments:

    Let’s say I have a main CAt called CARS and 3 sub-cats:
    1)Sports Cars
    2)Economic Cars
    3)4 x 4

    As we know now, if I have posts in cat #1 +2 +3, they will all show up under CARS – that is the standard in WP.

    Now with this code, if user click CAR he will get only the 3 sub cats WITHOUT any posts at all?

    Is this correct?

    Second question:

    Where do I add this code?

    Thanks

    Roger
