示例脚本

脚本非常灵活,可以用来创建独特且功能多样的折扣。例如,您可以创建一些脚本,这些脚本将根据客户添加的产品更改商店购物车中订单商品的价格和属性。

您可以在脚本编辑器提供的脚本模板中找到常用脚本的示例。若要查看这些示例,您需要创建脚本。

以下是一些其他脚本示例:

对所有产品给予百分比折扣

此订单项目脚本将购物车中每个订单项目的价格乘以0.9,从而提供 10% 的折扣。

Input.cart.line_items.each do |item|
  item.change_line_price(item.line_price * 0.9, message: "10% off all items!")
end

Output.cart = Input.cart

对所有运费给予百分比折扣

此配送脚本会为所有运费应用 0.10 的折扣,从而使运费降低 10%。

Input.shipping_rates.each do |shipping_rate|
  next unless shipping_rate.source == "shopify"
  shipping_rate.apply_discount(shipping_rate.price * 0.10, message: "Discounted shipping")
end

Output.shipping_rates = Input.shipping_rates

删除运费

此配送脚本会隐藏以字符串 EXPRESS 开头的发货选项。

Output.shipping_rates = Input.shipping_rates.delete_if do |shipping_rate|
  shipping_rate.name.upcase.start_with?("EXPRESS")
end

重命名支付服务提供商

以下脚本将货到付款 (COD) 支付服务提供商重命名为自定义名称。

Input.payment_gateways.each do |payment_gateway|
  next unless payment_gateway.name == "Cash on Delivery (COD)"
  payment_gateway.change_name("Custom Name")
end

Output.payment_gateways = Input.payment_gateways

阻止客户使用折扣码

您可以使用订单项目脚本暂时阻止客户在结账时应用折扣码。例如,在 Black Friday Cyber Monday 促销期间,可使用以下脚本告知客户无法使用折扣码:

if Input.cart.discount_code
  Input.cart.discount_code.reject(
    message: "Maximum discount already applied! Discount codes can not be used during this promotion."
  )
end

Output.cart = Input.cart

如果您具有 Shopify Plus 套餐,则可以从结帐中删除折扣码字段。若要删除此字段,请将以下代码添加到 checkout.liquid 文件。

<style>
[data-reduction-form="update"] {
  display: none
}
</style>
Ruby
# Use an array to keep track of the discount campaigns desired.
CAMPAIGNS = [
  # $5 off all items with the "sale" tag
  ItemCampaign.new(
    AndSelector.new(
      TagSelector.new("sale"),
      ExcludeGiftCardSelector.new,
    ),
    MoneyDiscount.new(5_00, "5$ off all items on sale",),
  ),

  # 10% off all items with a price lower than $100
  ItemCampaign.new(
    AndSelector.new(
      ExcludeGiftCardSelector.new,
      PriceSelector.new(:lower_than, Money.new(cents: 100_00)),
    ),
    PercentageDiscount.new(10, "10% off all items under 100$"),
  ),

  # Give every 3rd item with the tag "letter" for free
  BogoCampaign.new(
    TagSelector.new("letter"),
    PercentageDiscount.new(100, "Third item is free"),
    LowToHighPartitioner.new(2,1),
  )
]

# Iterate through each of the discount campaigns.
CAMPAIGNS.each do |campaign|
  # Apply the campaign onto the cart.
  campaign.run(Input.cart)
end

# To have the changes to the line items be reflected, the output of
# the script needs to be specified.
Output.cart = Input.cart

买一送一

在这些产品中,如果客户购买了至少一个产品,则此脚本将免费赠送一个产品。

# Buy One, Get One Free Script
# The basis of this script is provided by the Script Editor itself as a "default" script option.

# Adjusting these values lets you tweak the scope of the discount, eg:
# PAID_ITEM_COUNT = 1, DISCOUNTED_ITEM_COUNT = 1 -> Buy One, Get One
# PAID_ITEM_COUNT = 3, DISCOUNTED_ITEM_COUNT = 2 -> Buy Three, Get Two
PAID_ITEM_COUNT = 1
DISCOUNTED_ITEM_COUNT = 1

# Specify the IDs of the products you want to be eligible for this promotion.
ELIGIBLE_PRODUCT_IDS = [9307791812, 9307791940]

# Returns the integer amount of items that must be discounted next
# given the amount of items seen
#
def discounted_items_to_find(total_items_seen, discounted_items_seen)
  Integer(total_items_seen / (PAID_ITEM_COUNT + DISCOUNTED_ITEM_COUNT) * DISCOUNTED_ITEM_COUNT) - discounted_items_seen
end

# Partitions the items and returns the discounted items.
#
# Arguments
# ---------
#
# * cart
# The cart to which split items are added (typically Input.cart).
#
# * line_items
# The selected items that are applicable for the campaign.
#
def partition(cart, line_items)
  # Sort the items by price from high to low
  sorted_items = line_items.sort_by{|line_item| line_item.variant.price}.reverse
  # Create an array of items to return
  discounted_items = []
  # Keep counters of items seen and discounted, to avoid having to recalculate on each iteration
  total_items_seen = 0
  discounted_items_seen = 0

  # Loop over all the items and find those to be discounted
  sorted_items.each do |line_item|
    total_items_seen += line_item.quantity
    # After incrementing total_items_seen, see if any items must be discounted
    count = discounted_items_to_find(total_items_seen, discounted_items_seen)
    # If there are none, then skip to the next item
    next if count <= 0

    if count >= line_item.quantity
      # If the full item quantity must be discounted, then add it to the items to return
      # and increment the count of discounted items
      discounted_items.push(line_item)
      discounted_items_seen += line_item.quantity
    else
      # If only part of the item must be discounted, then split the item
      discounted_item = line_item.split(take: count)
      # Insert the newly-created item in the cart, right after the original item
      position = cart.line_items.find_index(line_item)
      cart.line_items.insert(position + 1, discounted_item)
      # Add it to the list of items to return
      discounted_items.push(discounted_item)
      discounted_items_seen += discounted_item.quantity
    end
  end

  # Return the items to be discounted
  discounted_items
end

eligible_items = Input.cart.line_items.select do |line_item|
  product = line_item.variant.product
  !product.gift_card? && ELIGIBLE_PRODUCT_IDS.include?(product.id)
end

discounted_line_items = partition(Input.cart, eligible_items)
discounted_line_items.each do |line_item|
  line_item.change_line_price(Money.zero, message: "Buy one, get one free!")
end

Output.cart = Input.cart

新客户折扣

此脚本对新客户给予百分比折扣。

DISCOUNT_AMOUNT = 20

if Input.cart.line_items.size > 1 && (Input.cart.customer.nil? || Input.cart.customer.orders_count < 1)
  line_item = Input.cart.line_items.sort_by { |line_item| line_item.variant.price }.first
  if line_item.quantity > 1
    line_item = line_item.split(take: 1)
    Input.cart.line_items << line_item
  end
  line_item.change_line_price(line_item.line_price * (1.0 - (DISCOUNT_AMOUNT / 100.0)), message: "#{DISCOUNT_AMOUNT}% off for first-time customers!")
end

Output.cart = Input.cart

对最便宜的商品给予百分比折扣

此脚本会对购物车中最便宜的产品应用百分比折扣。

DISCOUNT_AMOUNT = 15

if (Input.cart.line_items.size > 1)
  line_item = Input.cart.line_items.sort_by { |line_item| line_item.variant.price }.first
  if line_item.quantity > 1
    line_item = line_item.split(take: 1)
    Input.cart.line_items << line_item
  end
  line_item.change_line_price(line_item.line_price * (1.0 - (DISCOUNT_AMOUNT / 100.0)), message: "#{DISCOUNT_AMOUNT}% off!")
end

Output.cart = Input.cart

针对批量购买的分层定价

在客户往购物车中添加更多产品时,此脚本可以提供更高比例的折扣。例如,当客户购买 1 到 5 个产品时,可以获得 5% 的折扣,当客户购买 6 到 10 个产品时,则可以获得 10% 的折扣,以此类推。

# Define a list of price tiers.

按消费阈值给予分级折扣

随着购物车的总价值上升,此脚本会提供越来越高的折扣。例如,如果客户的订单超过 50 美元,则获得 5% 的折扣,如果客户的订单超过 100 美元,则获得 10% 的折扣,以此类推。

# Define spending thresholds, from lowest spend to highest cart value.
SPENDING_THRESHOLDS = [
  {
    spend: 3000, # spend amount (in cents)
    discount: 10 # percentage discount
  },
  {
    spend: 5000,
    discount: 15
  },
  {
    spend: 10000,
    discount: 20
  }
]

# Find any applicable spending threshold.
eligible_threshold = nil
SPENDING_THRESHOLDS.each do |threshold|
  if Input.cart.subtotal_price_was.cents >= threshold[:spend]
    eligible_threshold = threshold
  end
end

# Apply threshold.
if !eligible_threshold.nil?
  Input.cart.line_items.each do |line_item|
    line_item.change_line_price(line_item.line_price * (1.0 - (eligible_threshold[:discount] / 100.0)), message: "#{eligible_threshold[:discount]}% off for purchases over $#{eligible_threshold[:spend] / 100}!")
  end
end

Output.cart = Input.cart

通过购买获得免费礼品

此脚本可通过客户的购买行为向其提供免费礼品。您可以定义客户在一次购买中需要包含多少产品才能收到免费礼品。

# Define the ID of the free product.
FREE_GIFT_PRODUCT_ID = 9307791812

# Check that we have at least two items in the cart (so that there's a "purchase").
if Input.cart.line_items.size > 1
  Input.cart.line_items.each do |line_item|
    # If the free gift is found, set its price to zero.
    if line_item.variant.product.id == FREE_GIFT_PRODUCT_ID
      if line_item.quantity > 1
        line_item = line_item.split(take: 1)
        Input.cart.line_items << line_item
      end
      line_item.change_line_price(Money.zero, message: "Free gift with purchase!")
    end
  end
end

# Export the cart.
Output.cart = Input.cart

为特定客户群提供的免费标准配送服务

此脚本为指定的客户组提供免费送货。例如,您可以将某些客户标记为 VIP,然后为这些客户提供免费送货。

# Define a list of shipping service names that are eligible for free shipping for VIPs.
ELIGIBLE_SERVICES = ['Standard Ground Shipping']

# Define the tag that identifies VIP customers.
VIP_CUSTOMER_TAG = 'VIP'

# If the customer is a VIP, give them free shipping on the defined services.
if !Input.cart.customer.nil? and Input.cart.customer.tags.include?(VIP_CUSTOMER_TAG)
  Input.shipping_rates.each do |shipping_rate|
    if ELIGIBLE_SERVICES.include?(shipping_rate.name)
      shipping_rate.apply_discount(shipping_rate.price, message: "Free shipping for VIP customers!")
    end
  end
end

# Export the rates.
Output.shipping_rates = Input.shipping_rates

如果客户离特定位置很近,则可以到店取货

如果客户的邮政编码前缀与此脚本中设置的列表匹配,则此脚本允许客户到店取货。

# Define the name of the pick up shipping rate - this should be added manually in the Shopify Admin.
PICKUP_SHIPPING_RATE_NAME = 'Pick Up In-Store'

# Define a list of postcode prefixes that are allowed to pick up from the store.
PICKUP_POSTCODE_PREFIXES = [
  '100', '101', '102'
]

# Output filtered shipping rates.
Output.shipping_rates = Input.shipping_rates.delete_if do |shipping_rate|
  (shipping_rate.name == PICKUP_SHIPPING_RATE_NAME) && !PICKUP_POSTCODE_PREFIXES.any? { |prefix| Input.cart.shipping_address.zip.start_with?(prefix) }
end

如果客户接受营销,则对下一个订单应用百分比折扣

如果客户在首次下单时接受了营销,则该脚本会为该客户的下一个订单提供百分比折扣。

# Define the discount for eligible customers.
DISCOUNT_AMOUNT = 10

# Checks to see if this is a customer's second order, and that they opted into marketing when they placed their first order.
if (!Input.cart.customer.nil? && Input.cart.customer.orders_count == 1 && Input.cart.customer.accepts_marketing?)
  Input.cart.line_items.each do |line_item|
    line_item.change_line_price(line_item.line_price * (1.0 - (DISCOUNT_AMOUNT / 100.0)), message: "#{DISCOUNT_AMOUNT}% off for subscribing to our newsletter!")
  end
end

Output.cart = Input.cart

自动选择默认付款方式

此脚本会在结帐时自动选择指定的付款方式。

# Define the preferred order of gateways.
PREFERRED_GATEWAY_ORDER = ['Invoice', 'Shopify Payments']

# Sort gateways.
Output.payment_gateways = Input.payment_gateways.sort_by do |payment_gateway|
  PREFERRED_GATEWAY_ORDER.index(payment_gateway.name) || 999
end
