Display a list of sub-categories

Hi there,

how would you determine what list of sub categories were to be displayed on a Page?
If you were viewing a Category Archive then it would be possible to get the Parent Category and display a list of its children. But Pages won't have any idea of what sub categories you want displayed.

Getting the Parent Category to display a list of its children would work fine for me. How could I go about doing that?

Is this to be displayed on a Static Page ? Or a Category Archive ?

A static page would be preferable.

Hmmm... you could try creating a Shortcode that displays a list of Sub Categories of the given parent category.

Add this PHP Function to your site:

function display_subcategories( $atts ) {

    $atts = shortcode_atts( array(
        'category' => null
    ), $atts );

    $parent_cat_slug = get_category_by_slug( $atts['category'] );
    $parent_cat_ID = $parent_cat_slug->term_id;

    $args = array(
        'hierarchical' => 1,
        'hide_empty' => 0,
        'parent' => $parent_cat_ID,
        'taxonomy' => 'category'
    );
    $subcats = get_categories($args);
    ob_start();
    echo '<ul class="sub-categories">';
    foreach ($subcats as $subcat) {
        $link = get_term_link( $subcat->slug, $subcat->taxonomy );
        echo '<li><a href="' . $link . '">' . $subcat->name . '</a></li>';
    }
    echo '</ul>';

    return ob_get_clean();
}
add_shortcode( 'subcategory', 'display_subcategories' );

Then you can add the shortcode like so:

[subcategory category="category-slug"]

Change the category-slug to that of the parent category that you want to display the children of.

Works great, thanks so much, David!

Awesome - glad to be of help
