Get storeviews by group ID in magento?

Question

How to get storeview ID (view) by group_id (store) in Magento? Basically I want to list storeviews by their store_id.

Mage::app()->getStores() will get all storeviews, but I want to filter it by specific store group like

Mage::app()->getStores()->byGroupId($store_group_id);

so i can list all storeviews under a specific store.

Answer 1

$groupId = 1;
$collection = Mage::getModel('core/store')->getCollection()->addFieldToFilter('group_id', $groupId);
foreach ($collection as $store) {
    //do something with $store
}

Answer 2

You can use something like this

$stores = Mage::getModel('core/store')->getCollection()->addFieldToFilter('group_id',$store_group_id);
foreach($stores as $store)
{
    print_r($store->getData());
}

Answer 3

$stores = Mage::getResourceModel('core/store_collection')
    # $yourStoreGroupIds can be string or array of group ids
    ->addGroupFilter($yourStoreGroupIds);

foreach ($stores as $store) {
    ...
}

Technically the same as Marius answer because addGroupFilter uses

public function addGroupFilter($groupId)
{
    return $this->addFieldToFilter('main_table.group_id', array('in' => $groupId));
}

To just get the storeview IDs

$storeIds = $stores->getColumnValues('store_id');
