is there a chance to add ean to the orders, because I am trying to export my orders with another plugin but it doesn’t shows the items ean codes even I have entered the post meta key. I have looked the postmeta table an order data and didn’t see the _alg_ean key and value that’s the reason I cannot export my orders with ean codes.
Actually, the plugin already does that, i.e. it saves product EANs in order data. However, as an order can have multiple products and thus multiple EANs, the data is saved not in order meta (postmeta table) but in order item meta (woocommerce_order_itemmeta table).
If you still need help, please let me know which plugin are you using for the export, and I’ll check about the exact steps you need to take there.
P.S. You are correct about the key, it’s _alg_ean.
