Changing field value in orders table when order is placed

[rhoenig]

I'd like to modify the total_shipping field in the orders table once the customer clicks confirm order (using paypalpro module).  I've looked everywhere and can't figure out where the order is saved or where total_shipping is set.  

 

Any advice would be great.  I would like to find this in the core files and then will move it to the overrides.

 

Thank you
Robert

It's the validateOrder function in classes/PaymentModule.php that creates the order. It's lines 315-317 in PrestaShop v1.6.1.9 that set the shipping:

$order->total_shipping_tax_excl = (float)$this->context->cart->getPackageShippingCost((int)$id_carrier, false, null, $order->product_list);
$order->total_shipping_tax_incl = (float)$this->context->cart->getPackageShippingCost((int)$id_carrier, true, null, $order->product_list);
$order->total_shipping = $order->total_shipping_tax_incl;
