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!

This snippets will help you “get” the list of cross-sells that you’ve added in the edit product page.

PHP Snippet 1: Get Product Cross-Sells

/** * @snippet Get Product Cross-Sell IDs * @how-to Get CustomizeWoo.com FREE * @author Rodolfo Melogli * @compatible WooCommerce 7 * @donate $9 https://businessbloomer.com/bloomer-armada/ */ $product->get_cross_sell_ids();

PHP Snippet 2: Get Order Cross-Sells

This is as easy as looping through the order items, adding the cross sell IDs to an array, and remove the duplicates from the final array.

/** * @snippet Get Order Cross-Sell IDs * @how-to Get CustomizeWoo.com FREE * @author Rodolfo Melogli * @compatible WooCommerce 7 * @donate $9 https://businessbloomer.com/bloomer-armada/ */ $items = $order->get_items(); $cross_sells = array(); foreach ( $items as $item ) { $cross_sells = array_merge( $item->get_product()->get_cross_sell_ids(), $cross_sells ); } $cross_sells = array_unique( $cross_sells );

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files – if you need more guidance, please take a look at my guide “Should I Add Custom Code Via WP Editor, FTP or Code Snippets?” and my video tutorial “Where to Place WooCommerce Customization?”

Does this snippet (still) work?

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.
