I am trying to achieve the following:

When an item is Out of Stock send an E-Mail Notification to the warehouse. First question would be: what's the easiest and cleanest way to achieve this?!

My approach was:

I wrote an observer which fires on the sales_order_save_after event. So basically after every order all Items in this order should be checked wether these are still in Stock after the order.

The Observer.php looks like this:

public function checkStock($observer)
    $active = Mage::getStoreConfig('chimney_notifystock/general/notification_enabled');
    if ($active == 1){

        $order = $observer->getEvent()->getOrder();

        foreach ($order->getAllItems() as $item) {

            $product = $item->getProduct();
            $stockItem = $product->getStockItem();

            if ($stockItem->getIsInStock() == 0) {

Now the problem is that obviously on sales_order_save_after the value of is_in_stock isn't set to 0 yet. The getIsInStock() method always returns 1 so the sendMail() won't be executed. Everything else works fine and the e-mail is sent correctly when I set the
if ($stockItem->getIsInStock() == 0)
if ($stockItem->getIsInStock() == 1)


use event because it will called after the updating table data.

  • unfortunately for some reason this still doesn't work. When I complete the order the Stock is reduced correctly and if the stock hits 0 the product is set to "out of stock" but when I request the "is in stock status" or the qty from within the sales_order_save_commit_after i still get the qty from before the order and the product isn't set to out of stock yet. So this must be happening somewehere later on – Chaz Nov 6 '18 at 14:13
  • @Chaz did you tried to get new object of product data? – PROGOSTECH Nov 6 '18 at 15:09
  • What do you mean? How do I do that? How do I have to adjust my Code? – Chaz Nov 6 '18 at 15:59
  • @Chaz $product = $item->getProductId(); you will get id here . load new product data with model and check you will get the updated data. maybe you get the out of stock data correctly. – PROGOSTECH Nov 6 '18 at 16:01
  • When I load the $stockItem like this the qty gets updated like you said. The "is in stock" status however isn't any ideas when this happens? Anyways I think I can work with it like that, thank you very much! – Chaz Nov 6 '18 at 16:38
