Hi everyone!
I’m looking for a simple way to achieve the following:
I want to write a product description manually, for example when adding a new watch. Based on the content of that description, I’d like Shopify (or an app like Flow or similar) to automatically detect specific words — for example, “Mineralglas” — and then use that to populate a product metafield (in this case, a metafield for the type of glass).
Goal:
If I write “Mineralglas” somewhere in the product description, the system should automatically fill in the “Glas” metafield with the value “Mineralglas”.
I’ve tried doing this using Shopify Flow by checking if product.descriptionHtml contains the word and then using the “Update product metafield” action — but I keep running into errors when setting the value, even when using a text metafield.
So instead of asking what I’m doing wrong, I’d love to hear:
What’s the best way to achieve this kind of automation?
Is Shopify Flow the right tool, or should I approach this in another way?
Thanks in advance for any guidance!
