Goal: apply a discount when any metafield on products in the cart matches a metafield on the customer.
Context: The app creates custom metafields (stored as multi-line strings) on both products and customers. The author wants to use a Shopify Function (implemented in Rust) to iterate over product metafields and compare them to the customer’s metafields.
Key terms: Metafields = custom key–value fields for storing specialized data on Shopify resources. Shopify Functions = server-side extensions (written in Rust) that can run logic such as discounts.
Questions: 1) Can a Shopify Function directly access and loop through product and customer metafields to perform matching? 2) If not, what alternatives exist to accomplish this logic (e.g., using tags)?
Status: No answers or solutions provided yet; no code snippets or attachments; the request is for feasibility and potential approaches. Discussion open.
Good day!
I want to loop through all the metafields of products in the cart and see if they match metafields in the customer. If any of them match I want to apply a discount.
My app creats these custom metafields on the products and customers. They are just multi line strings.
Is it possible to loop through those metafields in the rust code of a shopify function like this?
If it is not possible how would I be able to achieve this in another way? Maybe using tags?
