Convert the price from Base Currency to USD at the stage of paypal payment?

Question

I have integrated PayPal to my website and PayPal does not support Base currency INR and support if Base Currency US Dollar.

Partial Working Method:

app\code\core\Mage\Paypal\Model\Express\Checkout.php

$this->_api->setAmount($this->_quote->getBaseGrandTotal())
            ->setCurrencyCode($this->_quote->getBaseCurrencyCode())
            ->setInvNum($this->_quote->getReservedOrderId())
            ->setReturnUrl($returnUrl)
            ->setCancelUrl($cancelUrl)
            ->setSolutionType($solutionType)
            ->setPaymentAction($this->_config->paymentAction);

Just replace the below code:

$this->_api->setAmount($this->_quote->getBaseGrandTotal())
            ->setCurrencyCode('USD')
            ->setInvNum($this->_quote->getReservedOrderId())
            ->setReturnUrl($returnUrl)
            ->setCancelUrl($cancelUrl)
            ->setSolutionType($solutionType)
            ->setPaymentAction($this->_config->paymentAction);

this one is working but the price Rs.70 displayed like $70 at my PayPal payment page. How to solve this issue?

How to convert the price from Base Currency to USD at PayPal payment?

Answer 1

Magento has a lot of functionality to convert currency. It is designed as a multi-lingual and multi-currency application.

The easiest way to convert from the base currency into the current selected store currency is with the following code:

$amount = Mage::app()->getStore()->convertPrice($baseAmount, false, false);

You can also use the directory helper:

/* @var $helper Mage_Directory_Helper_Data */
$helper = Mage::helper('directory');

// second param = 'from', third param = 'to'
$amount = $helper->currencyConvert($amount, 'USD', 'EUR');

To make sure your currency exchange rates are up to date, you need to enable cron for the magento website and make sure that the schedule imports are enabled:

Magento Admin > System Config > Currency Setup > Scheduled Import Settings

As you need the complete solution goes here,

$from_Currency='INR';
$to_Currency='USD';
$amount = urlencode($this->_quote->getBaseGrandTotal());
$from_Currency = urlencode($from_Currency);
$to_Currency = urlencode($to_Currency);
$url = "http://www.google.com/finance/converter?a=$amount&from=$from_Currency&to=$to_Currency";

$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$rawdata = curl_exec($ch);
curl_close($ch);
$data = explode('bld>', $rawdata);
if(count($data) < 2){
    $data[1] = '';
}
$priceinusd = explode($to_Currency, $data[1]);
$this->_api->setAmount($priceinusd)
        ->setCurrencyCode('USD')
        ->setInvNum($this->_quote->getReservedOrderId())
        ->setReturnUrl($returnUrl)
        ->setCancelUrl($cancelUrl)
        ->setSolutionType($solutionType)
        ->setPaymentAction($this->_config->paymentAction);

Try this

if you are not using the USD as a currency in your store you can use this code for conversion.

    $from_Currency='INR';
    $to_Currency='USD';
    $amount = urlencode('100');
    $from_Currency = urlencode($from_Currency);
    $to_Currency = urlencode($to_Currency);
    $url = "http://www.google.com/finance/converter?a=$amount&from=$from_Currency&to=$to_Currency";

    $ch = curl_init();
    $timeout = 0;
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $rawdata = curl_exec($ch);
    curl_close($ch);
    $data = explode('bld>', $rawdata);
    if(count($data) < 2){
        $data[1] = '';
    }
    $data = explode($to_Currency, $data[1]);

If you are using the USD as a currency in your store then you can use.

Mage::app()->getLocale()->currency('USD')->toCurrency($price);
