list subcategories

  • Hi there,

    in the old GP support forum I found this code to show the subcategories of a main category.
    https://generatepress.com/forums/topic/list-subcategories/#post-679474

    It works very well, but there is a small problem: it also shows the categories that are empty (not assigned to a post). Is it possible to customize the code so that empty categories are not shown?

    Thank you!

  • Hi there,

    Give this code a try:

    add_shortcode( 'list_subcats', function( $atts ) {
        $atts = shortcode_atts(
            array(
                'id' => '',
        ), $atts, 'list_subcats' );
    
        ob_start();
        
        $term_id = $atts['id'];
        $taxonomy_name = 'category';
        $term_children = get_term_children( $term_id, $taxonomy_name );
    
        echo '<ul class="list-subcats">';
    
        foreach ( $term_children as $child ) {
            $term = get_term_by( 'id', $child, $taxonomy_name );
            
            // Check if the term has any posts
            if ( $term->count > 0 ) {
                echo '<li><a href="' . get_term_link( $child, $taxonomy_name ) . '">' . $term->name . '</a></li>';
            }
        }
    
        echo '</ul>';
    
        return ob_get_clean();
    } );
