Add id carrier in cart through module

[Muzammil Mac]

Hi,

I'm creting a custom module and I am trying to add carrier id to cart. I'm running 1.7.6.5

The carrier id I want to set it to is 5, but when view it in  BO after order is  placed, it's using my default carrier with id 6

            $cart = new Cart($this->context->cookie->id_cart);
            $cart->id_address_delivery = 1;
            $cart->id_address_invoice = 1;
            $cart->id_carrier = 5;

What am I missing?

Thankyou in Advance.

You are not saving / updating the cart.

sorry i forgot to add that in code snippet. I am saving the cart and id_address is also working fine.

In the database, there is also the delivery_option column, maybe you also need to set this field for the carrier to be applied correctly.

I tried adding the delivery option but id carrier is still not working.
