I am currently working on a magento site that is in 2 languages (French and Dutch). The approach I am taking is as follows:
If the reason you're doing the htaccess stuff is so that you can generate URLs specific to each store, you may want to go with the configuration option that does that for you, should be in System > Config > Web
You will get all store details here
<?php
$allStores = Mage::app()->getStores();
foreach ($allStores as $_eachStoreId => $val)
{
$_storeCode = Mage::app()->getStore($_eachStoreId)->getCode();
$_storeName = Mage::app()->getStore($_eachStoreId)->getName();
$_storeId = Mage::app()->getStore($_eachStoreId)->getId();
echo $_storeId;
echo $_storeCode;
echo $_storeName;
}
?>
To redirect to the specified store, you need to redirect the page along with the store code.
http://www.mywebsite.com/index.php/store_code/
Please check the template/page/switch/stores.phtml for more details
After hours of huffing and puffing i was able to figure out a way to set the store id programatically :)
In the index.php file, (in your language specific folder), add the following:-
$store_id = 'your_store_id_here';
$mageRunCode = 'store view code';
$mageRunType = 'store';
Mage::app()->setCurrentStore($store_id);
Mage::run($mageRunCode, $mageRunType);
Hope someone will find this information useful :)
