How to get $params from validated order and execute some code after order

[hakeryk2]

Hello community,

 

I want to execute some code when order is validated but I want to have access to some data from order. How I can achieve that? In my case I want to add something to actionUpdateQuantity and actionValidateOrder hooks in my module but I don't know how I should call for parametrs like $id_product, $id_product_attribute, $quantity in 

 

 public function hookActionValidateOrder()

{

     //logic here with some vars that I would to know how to get

}

 

Any help will be very appreciated.
