How can I apply free shipping for multiple item tags?

Technical Q&A
1

I have a script that we use to give the customer free shipping based on if their cart contains all items with a specific tag, but I am wonder how to make it so we can use multiple tags. For example, if a customer has two items in their cart where product1 has a tag of “item1” and product2 has a tag of “item2”, the cart would show free shipping.

Here is my working script for a single tag:

FREE_TAG = 'Club:Murfreesboro SC'

if Input.cart.shipping_address.country_code == 'US' && Input.cart.line_items.all?{|item| item.variant.product.tags.include? FREE_TAG}
  Input.shipping_rates.each do |shipping_rate|
    next if shipping_rate.price == Money.zero
    shipping_rate.apply_discount(shipping_rate.price, message: "Free Shipping Item(s)!")
    break
  end
end

Output.shipping_rates = Input.shipping_rates

But I want something like this:

FREE_TAG = ['Club:Murfreesboro SC','Club:Northland United']

if Input.cart.shipping_address.country_code == 'US' && Input.cart.line_items.all?{|item| item.variant.product.tags.include? FREE_TAG}
  Input.shipping_rates.each do |shipping_rate|
    next if shipping_rate.price == Money.zero
    shipping_rate.apply_discount(shipping_rate.price, message: "Free Shipping Item(s)!")
    break
  end
end

Output.shipping_rates = Input.shipping_rates

Is there any way to have multiple tags in the FREE_TAG?

Thanks!

Hi Thomas, haven’t had a chance to test it, switching your script to this might work.

FREE_TAG = ['Club:Murfreesboro SC','Club:Northland United']

if Input.cart.shipping_address.country_code == 'US' && Input.cart.line_items.all?{ item.variant.product.tags.any? { |x| FREE_TAG.include?(x)} }
  Input.shipping_rates.each do |shipping_rate|
    next if shipping_rate.price == Money.zero
    shipping_rate.apply_discount(shipping_rate.price, message: "Free Shipping Item(s)!")
    break
  end
end

Output.shipping_rates = Input.shipping_rates

Let me know if that is helpful,

Hi Matthew,

Thank you for the help. It doesn’t seem to work and shows the following run error:

[Error] undefined method 'item' for main
  Free Shipping for Club Tag:3:in Object.call
  shopify/std_lib/core/list.rb:41:in List.each
  Free Shipping for Club Tag:3

Sorry, small typo:

FREE_TAG = ['Club:Murfreesboro SC','Club:Northland United']

if Input.cart.shipping_address.country_code == 'US' && Input.cart.line_items.all?{ |item| item.variant.product.tags.any? { |x| FREE_TAG.include?(x)} }
  Input.shipping_rates.each do |shipping_rate|
    next if shipping_rate.price == Money.zero
    shipping_rate.apply_discount(shipping_rate.price, message: "Free Shipping Item(s)!")
    break
  end
end

Output.shipping_rates = Input.shipping_rates

Matthew, that worked perfectly! Thank you so much!

Hi,

This script is exactly what I’ve been looking for. As fairly new to Shopify where would I place this script/ which file?

Thank you

You have to be on a Shopify Plus plan and install the Script Editor. Here is some more info: https://help.shopify.com/en/manual/checkout-settings/script-editor
