Three currencies in the online store on opencart?

Question

PHP

Hello, there is an online store on Opencart 1.5.5.1. I have three price lists from three suppliers, one in dollars, another in rubles and a third in euros. Prices are small, so I manually enter them on the site.
The question arose, in opencart, as I know, there is only one main currency. For example, now there are rubles. And you have to manually convert each price from the dollar and euro price list into rubles.
Is it possible to somehow add three fields with three prices in the admin panel in the product card. If you entered the price in dollars, then automatically let it be converted through the built-in opencart mechanisms into rubles and euros. Accordingly, if you entered the price in dollars, then it is converted into euros and rubles. And on the site, a person already chooses from the list with which currency it is better for him to work)

Answer 1

Most likely, in your admin panel, the product has not 3 prices, but one price, but there is a setting in which currency it is indicated.
Look for a ready-made plugin for opencart if this functionality is not available right away.
On the site, the currency switcher simply controls the price conversion.

Answer 2

In general, you have now described the built-in functionality of opencart. Enter additional currencies in the admin panel, enter the exchange rate (it does not update itself, but it can be automated in principle), then the buyer on the site has a list of currencies (usually at the top of the screen), where he selects the one he needs and sees all the prices in it.
