retrieve cross sell product in woocommerce

3 Views

I have been here for the last 5 hours trying to figure out something. I need to be able to fetch the cross sell id of a product in the woo commerce in the order confirmation email. Up to now I have 

         $items = $order->get_items(); 
        foreach ( $items as $item ) {
            $product_id = $item['product_id'];
            }

And this retrive the id of the product. As there is always just going to be one cross sell product how can I get the id of that product in a variable?

  2. First you need cross sell product id for that product
    so it can be like: 

    $crosssellProductIds   =   get_post_meta( get_the_ID(), '_crosssell_ids' );
$crosssellProductIds    =   $crosssellProductIds[0];

    Now as we have all related cross cell product’s id, let’s get there information 

    foreach($crosssellProductIds as $id):
    $crosssellProduct = wc_get_product( $id );
    print_r($crosssellProduct);
endforeach;
