我有两个产品类别

多语言数字营销（ID 75）

我试着使用这个代码，但没有成功

if( is_product_category(107 || 75) ) { 

$term = get_queried_object();

$parent = $term->parent;

if (!empty($parent)) {
    $child_of = $parent;
} else {
    $child_of = $term->term_id;
}

$terms = get_terms( array(
    \'taxonomy\'      => \'product_cat\',
    \'child_of\'      => $child_of,
) );

if ($terms) {
    foreach ( $terms as $category ) {

        $category_id = $category->term_id;
        $category_slug = $category->slug;
        $category_name = $category->name;
        $category_desc = $category->description;

        echo \'<div class="\'.$category_slug.\'">\';

        echo \'<h2>\'.$category_name.\'</h2>\';

        if ($category_desc) {
            echo \'<p>\'.$category_desc.\'</p>\';
        }

        $products_args = array(
            \'post_type\'     => \'product\', 
            \'tax_query\'     => array( 
                array(
                    \'taxonomy\' => \'product_cat\',
                    \'field\'    => \'term_id\',
                    \'terms\'    => $category_id, 
                ),
            ),
        );

        $products = new WP_Query( $products_args );

        if ( $products->have_posts() ) { // only start if we hace some products

            // START some normal woocommerce loop

            woocommerce_product_loop_start();

            if ( wc_get_loop_prop( \'total\' ) ) {

                while ( $products->have_posts() ) : $products->the_post();

                    /**
                     * Hook: woocommerce_shop_loop.
                     *
                     * @hooked WC_Structured_Data::generate_product_data() - 10
                     */
                    do_action( \'woocommerce_shop_loop\' );

                    wc_get_template_part( \'content\', \'product\' );

                endwhile; // end of the loop.

            }

            woocommerce_product_loop_end();

            // END the normal woocommerce loop

            // Restore original post data, maybe not needed here (in a plugin it might be necessary)
            wp_reset_postdata();

        }
