یک فایل با نام simple-likes-public.js در روت اصلی پوسته درست کنید و سپس محتویات زیر را در آن قرار دهید :

سپس کد زیر را قبل از بسته شدن تگ head قرار دهید :

برای استایل دادن به دکمه لایک نیز کد زیر را به فایل style.css قالب در انتهای بقیه کد ها قرار بدهید :

1 | <?php echo get_simple_likes_button( get_the_ID() ); ?> |
هنوز تموم نشده ! برای اضافه کردن دکمه لایک به نظرات هم تکه کد زیر استفاده کنید :
1 | echo get_simple_likes_button( get_comment_ID(), 1 ); |
