From version 1.1.3.
We use product tags as tag trigger to setup upsell for each product. Tag trigger syntax : “upsell_<your_trigger_name>“. Example : upsell_jewelry1 .
Note : trigger name must be lowercase, only use alphabet and number.
Add trigger tag for the products you want to display as upsell of one of them. Ex : add trigger tag “upsell_jewelry1” for products A, B, C.
-> So upsell products of A are B, C. And upsell products of B are A, C and A, C for B.
Unlimited the number of trigger tags for a product. You can add mutiple trigger tags for a product if you want.
Note : the products exist in cart will be not displayed in upsell.
