OK, I got it to work. Just if someone else also wants to have this feature, here my approach:
At first some remarks:
Do not overwrite core code and create a module instead!
This only works fine if customers can only checkout in base currency! Otherwise there could be problems in admin panel. How to achieve this: http://www.magentocommerce.com/boards/viewthread/237750/
bugs: when selecting a configurable option, only the price in base currency changes, since there is no update method for the foreign currency yet.
Manual:
Make a Module and overwrite app/code/core/Mage/Directory/Model/Currency.php
My new class looks like that:
<?php
/**
* Currency model
*
* @category Mage
* @package Mage_Directory
* @author Magento Core Team <core@magentocommerce.com>
*/
class MyCode_TwoCurrencies_Model_Currency extends Mage_Directory_Model_Currency
{
/**
* Convert price to currency format
*
* @param double $price
* @param string $toCurrency
* @return double
*/
// public function convert($price, $toCurrency=null)
//never changes the currency, so displayed is always basecurrency
public function convert($price, $toCurrency=null, $staybase=true)
{
if (is_null($toCurrency) || $staybase) {
return $price;
}
elseif ($rate = $this->getRate($toCurrency)) {
return $price*$rate;
}
throw new Exception(Mage::helper('directory')->__('Undefined rate from "%s-%s".', $this->getCode(), $toCurrency->getCode()));
}
/**
* Apply currency format to number with specific rounding precision
*
* @param float $price
* @param int $precision
* @param array $options
* @param bool $includeContainer
* @param bool $addBrackets
* @return string
*/
public function formatPrecision($price, $precision, $options=array(), $includeContainer = true, $addBrackets = false)
{
if (!isset($options['precision'])) {
$options['precision'] = $precision;
}
//get current currency. if is base currency use standard return
$currencycode = Mage::app()->getStore()->getCurrentCurrencyCode();
$basecode = Mage::app()->getStore()->getBaseCurrencyCode();
if ($includeContainer) {
if ($currencycode==$basecode){
return '<span class="price">' . ($addBrackets ? '[' : '') . $this->formatTxt($price, $options) . ($addBrackets ? ']' : '') . '</span>';
//if not return base currency and in brackets the foreign currency ($currprice)
} else {
$currencyrate = Mage::app()->getStore()->getCurrentCurrencyRate();
//calculat price in foreign currency
$currprice=$price*$currencyrate;
$addBrackets=true;
return '<span class="price">'.$this->formatTxt($price, $options,true).'</span> <span class="bprice">' . ($addBrackets ? '[' : '') . $this->formatTxt($currprice, $options) . ($addBrackets ? ']' : '') . '</span>';
}
}
if ($currencycode==$basecode){
return $this->formatTxt($price, $options);
} else {
$currencyrate = Mage::app()->getStore()->getCurrentCurrencyRate();
$currprice=$price*$currencyrate;
$addBrackets=true;
return '<span class="price">'.$this->formatTxt($price, $options,true).'</span> <span class="bprice">' . ($addBrackets ? '[' : '') . $this->formatTxt($currprice, $options) . ($addBrackets ? ']' : '') . '</span>';
}
}
// public function formatTxt($price, $options=array())
//formats the price in base format or in current currency format depending in $base
public function formatTxt($price, $options=array(),$base=false)
{
if (!is_numeric($price)) {
$price = Mage::app()->getLocale()->getNumber($price);
}
$basecode = Mage::app()->getStore()->getBaseCurrencyCode();
$code = ($base) ? $basecode : $this->getCode();
/**
* Fix problem with 12 000 000, 1 200 000
*
* %f - the argument is treated as a float, and presented as a floating-point number (locale aware).
* %F - the argument is treated as a float, and presented as a floating-point number (non-locale aware).
*/
$price = sprintf("%F", $price);
return Mage::app()->getLocale()->currency($code)->toCurrency($price, $options);
}
//is important for configurable products! this price is formatted by javascript and uses this function for the pattern.
public function getOutputFormat()
{
$formated = $this->formatTxt(0,array(),true);
$number = $this->formatTxt(0, array('display'=>Zend_Currency::NO_SYMBOL));
return str_replace($number, '%s', $formated);
}
}
