Magento: How to get product stock quantity & other stock information?

You can use the following code to get any product’s stock information 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.

First load the product. Product can be loaded in different ways. the two different ways to load any product in Magento:-

1. Load product by product ID

$id = 52;
$_product = Mage::getModel('catalog/product')->load($id);

2. Load product by SKU

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

Now, get stock information for the loaded product.

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

You can check stock data in this way:-

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

Or, you can print individually like this:-

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

Product status (in stock/out of stock)

$stock = $product->getStockItem();
if ($stock->getIsInStock()) {
echo "product is in stock";
} else {
echo "product is not in stock";
}
