دریافت اطلاعات لیست مقایسه

سلام و عرض خسته نباشید
من یک سری محصول ویژه در صفحه اصلی فروشگاه اینترنتیم دارم. وقتی یک مشتری اونها رو به لیست مقایسه اضافه میکنه، اون کالا رنگ دکمه رو تغییر میده.
حالا من دنبال تابعی میگردم که بتونم اطلاعات لیست مقایسه رو بگیرم و ببینم کالایی که مشتری الان داره مشاهده میکنه، توی لیست مقایسه هست یا نه. اگر هست، رنگ دکمه متفاوت باشه.
آیا کسی میتونه کمکم کنه؟

من از ناپ کامرس 4.00 استفاده میکنم

با سلام
با این راه حل، وقتی یک محصول به لیست مقایسه افزوده شود، سیستم کلاس CSS با نام in-compare-list"" را به ریشه ی تگ جزئیات محصول/نمایش جعبه ای محصول می افزاید. بنابراین شما میتوانید استایل هر یک از عناصر زیرمجموعه را تغییر دهید.

یک پوشه با نام Features در پروژه ی Nop.Web ایجاد کنید.
در پوشه ی Features دو کلاس جدید با نام های CustomProductModelFactory و DependencyRegistrar ایجاد نمایید و کدهای زیر را در آن ها قرار دهید:
