如何通过Magento中的资源模型获取“库存”产品的集合

Question

Is it possible to fetch the collection of "in stock" products through resource model in Magento ?

I have tried this code

$collection = Mage::getResourceModel('catalog/product_collection')
        ->addAttributeToSelect('*');
$collection->addAttributeToFilter('is_in_stock', 0);

But it is throwing Fatal error

Answer 1

try below code

$productCollection = Mage::getResourceModel('catalog/product_collection');
Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($productCollection);
echo "<pre>";print_r($productCollection->getData());

// use addInStockFilterToCollection()

Answer 2

Just add at the end of product collection code

Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($productCollection);
