Solved: How To Override Product_Reference Setting In Orderdetail.php?

[JuanTomas]

Using Prestashop 1.6.1.2

 

In classes/order/OrderDetail.php we have function create(...) which sets product reference seen on invoice:

 

class OrderDetailCore extends ObjectModel
{

    ...

    /** @var string */
    public $product_reference;

    ...

    protected function create(Order $order, Cart $cart, $product, $id_order_state, $id_order_invoice, $use_taxes = true, $id_warehouse = 0)
    {

        ...

        $this->product_reference = empty($product['reference']) ? null : pSQL($product['reference']);

        ...

    }

}

 

I want to customize the behavior of the reference field on the invoice in override/classes/order/OrderDetail.php:

 

class OrderDetail extends OrderDetailCore
{
    protected function create(Order $order, Cart $cart, $product, $id_order_state, $id_order_invoice, $use_taxes = true, $id_warehouse = 0)
    {
        parent::create($order, $cart, $product, $id_order_state, $id_order_invoice, $use_taxes, $id_warehouse) ;

        ...some code which generates $my_custom_product_reference...

        // next line of code has no effect, the product_reference field doesn't actually get changed

        $this->product_reference = $my_custom_product_reference ;

    }

}

 

I'm a little unclear on OOP in php, but I can kind of see why this doesn't work.  So I'm considering some options...

• Modify classes/order/OrderDetail.php (PS core mod, upgrade will break)
• Try to figure out how to get the instance of OrderDetailCore and set $product_reference directly (it's public).
• Develop a module and hook actionValidateOrder, then modify ps_order_detail.product_reference directly in the database.  I'm not sure how the module can find out the order id or reference when the hook function is called.
• Override classes/order/OrderHistory.php and directly modify the database when an order's OrderState is set to FLAG_PAID

Any insights or ideas will be much appreciated!

did you try adding save or update?

class OrderDetail extends OrderDetailCore
{
    protected function create(Order $order, Cart $cart, $product, $id_order_state, $id_order_invoice, $use_taxes = true, $id_warehouse = 0)
    {
        parent::create($order, $cart, $product, $id_order_state, $id_order_invoice, $use_taxes, $id_warehouse) ;
        ...some code which generates $my_custom_product_reference...
        // next line of code has no effect, the product_reference field doesn't actually get changed
        $this->product_reference = $my_custom_product_reference;
        $this->save();
    }
}

Works a treat!  Thanks, bellini13!
