请尝试使用此代码

if(is_category()) {

    $breakpoint = 0;
    $thiscat = get_term( get_query_var('cat') , 'category' );
    $subcategories = get_terms( 'category' , 'parent='.get_query_var('cat') );

    if(empty($subcategories) && $thiscat->parent != 0) {
        $subcategories = get_terms( 'category' , 'parent='.$thiscat->parent.'' );
    }

    $items='';
    if(!empty($subcategories)) {
        foreach($subcategories as $subcat) {
            if($thiscat->term_id == $subcat->term_id) $current = ' current-cat'; else $current = '';
            $items .= '
            <li class="cat-item cat-item-'.$subcat->term_id.$current.'">
                <a href="'.get_category_link( $subcat->term_id ).'" title="'.$subcat->description.'">'.$subcat->name.' ('.$subcat->count.' posts)</a>
            </li>';
        }
        echo "<ul>$items</ul>";
    }
    unset($subcategories,$subcat,$thiscat,$items);
}
?>
