Witam mam poniższy kod który działa w następujący sposób tzn. po wybraniu języka wyświetla się wybór waluty. Po wybraniu $ do adresu ma dopisać wartość "/?currency_id=3"i podobnie przy wyborze €. Mam problem ponieważ chciałbym zrobić tak że jeżeli po wyborze € dopisywało wartość "/?currency_id=2" ale jednocześnie kasowało wartość "/?currency_id=3" jeżeli ktoś wcześniej wybrał $.
