Get all manufacturers for a particular store

The following code gets me all the manufacturers in all my stores:

$attribute = Mage::getSingleton('eav/config')->addStoreFilter($storeId)->getAttrib开发者_高级运维ute('catalog_product', 'manufacturer');
if ($attribute->usesSource()) {
    $options = $attribute->getSource()->getAllOptions(false);
}

However I have multiple stores and I only want the manufacturers for my chosen store id.

I've tried adding store filters to this but with no luck.

Any one have any ideas how to filter this by store?

$product = Mage::getModel('catalog/product');
$storeId = Mage::app()->getStore()->getId();    

$attributes = Mage::getResourceModel('eav/entity_attribute_collection')
    ->setStoreId($storeId);
    ->setEntityTypeFilter($product->getResource()->getTypeId())
    ->addFieldToFilter('attribute_code', 'manufacturer') // This can be changed to any attribute code
    ->load(false);


$attribute = $attributes->getFirstItem()->setEntity($product->getResource());

/* @var $attribute Mage_Eav_Model_Entity_Attribute */
$manufacturers = $attribute->getSource()->getAllOptions(false);
return $manufacturers;

This should do it. You can lower the attribute to select on.

 $product    = Mage::getModel('catalog/product');
 $products   = $product->setStoreId($storeId)->getCollection()
                 ->addAttributeToSelect(array('name', 'price', 'small_image','short_description','manufacturer'), 'inner');

        $this->setProductCollection($products);

See this blog post: http://www.sharpdotinc.com/mdost/2009/04/06/magento-getting-product-attributes-values-and-labels/

Go to the section labled "How to get Only the Attribute Values that have been used on products"

I got the list of manufacturer from the current store using product count

    public function getAllManu()
{
  $product = Mage::getModel('catalog/product');
  $attributes = Mage::getResourceModel('eav/entity_attribute_collection')
              ->setEntityTypeFilter($product->getResource()->getTypeId())
              ->addFieldToFilter('attribute_code', 'manufacturer'); //can be changed to any attribute
  $attribute = $attributes->getFirstItem()->setEntity($product->getResource());
  $attrMenuItems = $attribute->getSource()->getAllOptions(false);

    foreach ($attrMenuItems as $key => $value) {
       $collection = Mage::getModel('catalog/product')->getCollection();
       $collection->addFieldToFilter(array(array('attribute' => 'manufacturer', 'eq' => $value['value'])));
       $numberOfProducts = count($collection);
       $attrMenuItems[$key]['products_count'] = $numberOfProducts;
    }   

  return $attrMenuItems;
}
