解释

Shopify Metafields 是一种用于存储和管理自定义数据的功能。它们允许商户在商城中的产品、订单、客户、Page等对象上添加自定义字段，以满足特定业务需求。

操作

1、添加Custom data

可以为Products、Pages添加自定义数据，比如选择了Pages，那么在任何Page模板下配置了metafield的值，可以用page.metafields.custom.metafield_name.value访问添加的特定类型的元字段内容，又比如选择了Products，那么在product模板下，可以用product.metafields.custom.metafield_name.value访问为产品添加的特定数据的元字段内容，Collections同上，其它的比如Orders也有特定的用法。

就拿pages做举例

2、选择特定类型的数据

为Pages添加自定义内容的数据type，可以有普通数据type：文本、日期、布尔、json、整数等，也可以有引用数据type：product、file、collection、page等。

3、为Page配置元子段和值

选择一个页面

show all

配置元字段值

4、模板访问

在page.xxx.json，通过.value访问元字段内容

{{ page.title }}
