Magento: Get Product Collection by Type

Products can be of different types in Magento. The different product types are Simple Product, Configurable Product, Bundle Product, Grouped Product, Downloadable Product, and Virtual Product. For example: Chair can be a Simple Product. Shoes can be of different color and size. So, shoes falls under Configurable product. A downloadable mp3 music file will fall under Downloadable product.

The following code shows how to fetch product collection by particular product type, i.e. fetching all products which falls under a particular product type. If I want to fetch all Configurable products then I will pass the type_id as ‘configurable‘.

Here is the code:-

$collectionSimple = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'simple'));
				
$collectionConfigurable = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'configurable'));
				
$collectionBundle = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'bundle'));
				
$collectionGrouped = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'grouped'));
				
$collectionVirtual = Mage::getResourceModel('catalog/product_collection')
				->addAttributeToFilter('type_id', array('eq' => 'virtual'));

Hope this helps. Thanks.
