Losowe wyświetlanie produktów - ps specials

[Burnago]

Dzień dobry,

Korzystam z dwóch modułów które były w preście od początku. Jeden z nich to moduł wyświetlający produkty w promocji - ps specials oraz drugi - featured products wyświetlający produkty z danej kategorii.

Głównie chciałem się zająć tym modułem ps specials.

Zależy mi na tym aby produkty które wyświetlają się na stronie głównej pojawiały się albo losowo z uwzględnieniem czasu ważności plików cookies (o odświeżeniu przeglądarki i po wejściu na stronę ponownie były niezmienione przez jakiś czas) albo przesortowane pod względem czasu do końca promocji. Wszystko zależy od tego które rozwiązanie jest prostsze. 

Czy ktoś wykonywał taką drobną modyfikację? Przeszukałem internet ale proponowane rozwiązania nie są do tego modułu. 

Jeżeli ktoś ma jakiś pomysł było by miło  

 

Wersja presty 1.7.6.1. Domena bluewear.online.

Oto plik php modułu:
