从url去除掉category和父级的categroy slug

add_filter('term_link', 'remove_parent_category_slug', 10, 3);

function remove_parent_category_slug($termlink, $term, $taxonomy) {
    // Only apply to categories
    if ($taxonomy === 'category') {
        // Check if the term has a parent
        if ($term->parent != 0) {
            // Get the slug of the current term
            $termlink = home_url('/' . $term->slug . '/');
        }
    }
    return $termlink;
