Question

There is a site on bitrix, you need to make a filter to select the currency on the entire site, how can this be done?

Answer 1

To display the currency switch itself, you can write your own component. The list of currencies can be obtained by a request from this ORM class https://dev.1c-bitrix.ru/api_d7/bitrix/currency/cu...
Basically, product prices are shown in the components bitrix:catalog and bitrix:
catalog.section to display prices in the required currency, you need to set 2 parameters in the component: CURRENCY_ID and CONVERT_CURRENCY. You can read about them here .
BUT!!! - the purchase of goods in different currencies cannot be done in this way. I talked with Bitrix TP on this topic. Here is a quote from their answer: " The implementation of multi-currency is not provided in the architecture of the store module. ".
The price from the settings will eventually pop up:
(and this is not a complete list)
Thus, you can make a conclusion on the website of prices in different currencies, but the purchase will take place only at the price specified in the settings of the Online Store module.
