Shipping based on number of items

[ja-gallagher]

Hi,

Wondering if anyone knows if it's possible to calculate shipping based on the number of items in an order?
I can only see options for flat-rate and by weight.

Thanks in advance!

In your own plugin boot method, You can listen for cart's events :

public function boot()
{
    Event::listen('mall.cart.product.added', '\Acme\Mall\Classes\CartHandler');
    Event::listen('mall.cart.product.updated', '\Acme\Mall\Classes\CartHandler');
    Event::listen('mall.cart.product.removed', '\Acme\Mall\Classes\CartHandler');
    // ...
}

And in your own cart handler class you can set the shipping price according to your rules :

// \Acme\Mall\Classes\CartHandler
class CartHandler
{
    public function handle($cartProduct, $oldQuantity = null, $newQuantity = null)
    {
        $cart = Cart::byUser(Auth::getUser());

        // Do your shipping calculations
        $shippingPrice = 400;
        

        // Set cart shipping price according to the documentation
        // https://offline-gmbh.github.io/oc-mall-plugin/development/cart-model.html#enforce-shipping-price
        // 
        $cart->forceShippingPrice(
            ShippingMethod::getAvailableByCart($cart)->first()->id,
            ['EUR' => $shippingPrice],
            'Optional, alternative name'
        );
    }
}
