What is the difference between out of stock and 0 of stock?
I have an extension that automatically displays products from the same category as related products, however it displays products that are out of stock as well.
I checked in system configurations/inventory/stock options Display Out of Stock Products NO
In it's code it does not check for quantity left, it checks for stock value. So do I need to set up a stock value for every product? If so how do I do it?
I found this in the code of the extension
$products->getSelect()->order(new Zend_Db_Expr('RAND()')); Mage::getModel('cataloginventory/stock')->addInStockFilterToCollection($products); $this->setData('related_products', $products);
