[Magento] Change store's language and currency according to customer's GeoIP?
It is brilliant that your online store or shop can show customers' native language and currency when they access your stores.This is dynamic and charming feature we want to achieve in Magento. Luckily, Magento supports multiple-language and currency in one installation. I will try to use GeoIP database data to integrate with Magento.
When you run Magento store, there is one step called storeinitialization. From code's viewpoint, it is that index.php calls the methods in Mage class and Mage class calls the methods in Mage_Core_Model_App class. InMage_Core_Model_App class, the store you run is initialized as below:
protected function _initCurrentStore($scopeCode, $scopeType)
{
Varien_Profiler::start('mage::app::init::stores');
$this->_initStores();
Varien_Profiler::stop('mage::app::init::stores');
if (empty($scopeCode) && !is_null($this->_website)) {
$scopeCode = $this->_website->getCode();
$scopeType = 'website';
}
switch ($scopeType) {
case 'store':
$this->_currentStore = $scopeCode;
break;
case 'group':
$this->_currentStore = $this->_getStoreByGroup($scopeCode);
break;
case 'website':
$this->_currentStore = $this->_getStoreByWebsite($scopeCode);
break;
default:
$this->throwStoreException();
}
if (!empty($this->_currentStore)) {
$this->_checkCookieStore($scopeType);
$this->_checkGetStore($scopeType);
}
$this->_useSessionInUrl = $this->getStore()->getConfig(
Mage_Core_Model_Session_Abstract::XML_PATH_USE_FRONTEND_SID);
return $this;
}In regard to stores, It has default currency and language, but we can also use class Mage_Core_Model_Store's method to change the currency the store is using.
public function setCurrentCurrencyCode($code)
{
$code = strtoupper($code);
if (in_array($code, $this->getAvailableCurrencyCodes())) {
$this->_getSession()->setCurrencyCode($code);
if ($code == $this->getDefaultCurrency()) {
Mage::app()->getCookie()->delete(self::COOKIE_CURRENCY, $code);
} else {
Mage::app()->getCookie()->set(self::COOKIE_CURRENCY, $code);
}
}
return $this;
}Since we know how to change the currency, the left question is how we get the customer's country and currency information when they visit your site. GeoIP data gives us the answer.First of all, we can get the customer's IP when he comes to your
stores.
$ip = $_SERVER['REMOTE_ADDR'];The next step is to find the country and currency based on the GeoIP database.

As for the language, it is related to locale. The language changes with the locale's variation. We can use Mage_Core_Model_Locale'ssetLocale() method to change the locale according to customer's country.
public function setLocale($locale = null)
{
if (($locale !== null) && is_string($locale)) {
$this->_localeCode = $locale;
} else {
$this->_localeCode = $this->getDefaultLocale();
}
Mage::dispatchEvent('core_locale_set_locale', array('locale'=>$this));
return $this;
}
