How to set Currency by default Billing Address Country in Magento 1.9?

Question

In my setup only logged in customers can see prices and order. How to set currency due to their default billing address?

Thanks!

Answer 1

Since there is no built in mapping between countries and currencies, you have to do this on your own.

For setting current currency depending on customers billing address you can add an observer for customer_login event with this code:

public function setStoreCurrency(Varien_Event_Observer $observer)
{
    $mapping = array (
        {country_code} => {currency_code},
        ...
    );

    $customer = $observer->getCustomer();
    $countryCode = $customer->getDefaultBillingAddress()->getCountry();
    if (isset($mapping[$countryCode]) && !is_null($mapping[$countryCode])) {
        Mage::app()->getStore()->setCurrentCurrencyCode($mapping[$countryCode]);
    }
}

Further steps:

• enable currencies from system config - (General -> Currency Setup -> Allowed Currencies)
• set exchange rate - (System -> Mangage Currency -> Rates)

Notes:

• changing storeview als changes currency to storeviews default one
• if customers billing address currency is not allowed, nothing happens

For currency mapping you can use this:

$mapping = array (
