Woocommerce: Get all orders for a product

Question

In the Woocommerce API I see a method wc_get_orders

WooCommerce Order Functions

In the mentioned args I do not see an argument in which I could provide a product ID or Object to limit order results only for that specific product.

Is there a way I could filter orders only for specific products?

I need to use this method since some arguments are necessary

Edited This function doesn't exist, but it can be built. So the function below will return an array of all orders IDs for a given product ID, making the right SQL query:

/**
 * Get All orders IDs for a given product ID.
 *
 * @param  integer  $product_id (required)
 * @param  array    $order_status (optional) Default is 'wc-completed'
 *
 * @return array
 */
function get_orders_ids_by_product_id( $product_id, $order_status = array( 'wc-completed' ) ){
    global $wpdb;

    $results = $wpdb->get_col("
        SELECT order_items.order_id
        FROM {$wpdb->prefix}woocommerce_order_items as order_items
        LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
        LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID
        WHERE posts.post_type = 'shop_order'
        AND posts.post_status IN ( '" . implode( "','", $order_status ) . "' )
        AND order_items.order_item_type = 'line_item'
        AND order_item_meta.meta_key = '_product_id'
        AND order_item_meta.meta_value = '$product_id'
    ");

    return $results;
}

USAGE 1 (for a given product ID 37 and default Completed orders status):

$orders_ids = get_orders_ids_by_product_id( 37 );

// The output (for testing)
print_r( $orders_ids );

USAGE 2 (for a given product ID 37 and some defined orders statuses):

// Set the orders statuses
$statuses = array( 'wc-completed', 'wc-processing', 'wc-on-hold' );

$orders_ids = get_orders_ids_by_product_id( 37, $statuses );

// The output (for testing)
print_r( $orders_ids );

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works.
