[octagonal elf]

Hi. I am trying to get all attributes ID from product ID, and I tried below it does not work... any idea?

 

 

 

$attributes = $product->getAttributeCombinations($context->language->id);

foreach($attributes as $attribute ){

         $update_quantity = StockAvailable::updateQuantity($product['id_product'], $attribute, -(int)$product['cart_quantity']);

}

you should use $attribute['id_product_attribute'] as parameter, when you pass it to the upateQuantity ($attribute as you wrote it is an array)
