是的，您可以创建自己的简码，例如[productsrandom]
代码应该是这样的：

add_shortcode( 'productsrandom', 'bbloomer_custom_products_shortcode' );

function bbloomer_custom_products_shortcode() {
   $product_ids = array( 15876, 15877, 15878, 15879 ); // MANUAL IDS
   $remaining_product_ids = wc_get_products( 
      'status' => 'publish',
      'exclude' => $product_ids,
      'limit' => 12 - count( $product_ids ),
      'return' => 'ids',
   );
   $all_product_ids = implode( ',', array_merge( $product_ids, $remaining_product_ids ) );
   return do_shortcode( '[products limit="12" columns="4" orderby="rand" ids="' . $all_product_ids . '" class="post-products-end"]' );
}
