Getting the list of cross-sells for a WooCommerce product is actually super easy (yes, it’s one line of PHP). But what if you need to “calculate” the list of cross-sells for an entire order, made of different products?
In this short tutorial for developers we’ll see both: how to get the cross-sell IDs for a product, and how to get the entire range of cross-sells based on what’s been purchased in a given order. Enjoy!
Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
