Magento 1.9 – Auto-Change Stock Availability on Quantity Update

admin-panelmagento-1.9out-of-stockstock-status

assume the product quantity is "0", once we edit the quantity to "1". again we have to change from

"out of stock" to " in stock" to buy in site

So I’ve been looking for a way to change the Stock Availability back to In Stock when the quantity field is greater than 0.

here someone posted solution : https://stackoverflow.com/questions/7168295/magento-auto-changing-the-stock-availability-from-out-of-stock-to-in-stock

we can use Magento event catalog_product_save_after. Create an observer method that does the following on event catalog_product_save_after.

can anyone please explain me in detail what and all needs to be done for this. means in which file which code we have to add ?

public function catalog_product_save_after($observer) {
    $product = $observer->getProduct();
    $stockData = $product->getStockData();

    if ( $product && $stockData['qty'] ) {
        $stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product->getEntityId()); // Load the stock for this product
        $stock->setData('is_in_stock', 1); // Set the Product to InStock                               
        $stock->save(); // Save
    }
}
