Shopify脚本-

我想结合Shopify提供的两个示例脚本：

（） （）

因此，折扣仅适用于具有特定标签（例如折扣产品）的产品，适用于具有特定标签（客户折扣）的客户

我已经尝试了好几次，但似乎都没能成功

下面是一个尝试组合这两个脚本的示例：

# ================================ Customizable Settings ================================
# ================================================================
# Discounts by Customer Tag
#
# If a customer is tagged (or not, depending on the setting below)
# with the entered tag(s), the entered discount will be applied to
# each item in the cart.
#
#   - 'customer_tag_match_type' determines whether we look for the customer
#     to be tagged with any of the entered tags or not. Can be:
#       - ':include' to check if the customer is tagged
#       - ':exclude' to make sure the customer isn't tagged
#   - 'customer_tags' is a list of tags to identify qualified
#     customers
#   - 'discount_type' is the type of discount to provide. Can be
#     either:
#       - ':percent'
#       - ':dollar'
#   - 'discount_amount' is the percentage/dollar discount to
#     apply (per item)
#   - 'discount_message' is the message to show when a discount
#     is applied
# ================================================================

你具体尝试了什么？你在哪里遇到了麻烦？请更具体一点，这样我们可以帮助你。如果你的问题太广泛，我们就无法解决。@user1438038我用一个试图组合脚本的示例更新了原始帖子。
