Get product stock information in Magento

In this tutorial I will show you how to get product stock information in Magento. It will help you to get stock information of any product like quantity (qty), minimum quantity (min_qty), stock availability (is_in_stock), minimum and maximum sale quantity (min_sale_qty and max_sale_qty), etc.

To get stock data first you need to load the product. Following are two different ways to load any product in Magento.

By Product ID:

$_productId = '123';
$_product = Mage::getModel('catalog/product')->load($_productId);

By Product SKU:

$sku = "ADFM002";
$_product = Mage::getModel('catalog/product')->loadByAttribute('sku', $sku);

Now get stock information of the loaded product as below:

$stockInfo = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product);

You can check the stock information as below:

echo "
<pre>"; print_r($stockInfo->getData()); echo "</pre>

";

You may get individual field info like below:

echo $stockInfo->getQty();
echo $stockInfo->getMinQty();
echo $stockInfo->getMinSaleQty();

I hope this tutorial will help you.
