PHP Fatal error: Uncaught Error: Call to undefined function wc_get_order()

This is error I’m getting on version 5.1.0.

PHP Fatal error: Uncaught Error: Call to undefined function wc_get_order()

I suspect the WooCommerce class hasn’t been instantiated when I go to run this function, but it’s pretty straight forward (I think).

function bought( $id ) {

    $bought = false;

    // Set HERE ine the array your specific target product IDs
    $prod_arr = array( $id );

    // // Get all customer orders
    $customer_orders = get_posts( 
                            array(
                                'posts_per_page' => -1,
                                'meta_key'    => '_customer_user',
                                'meta_value'  => get_current_user_id(),
                                'post_type'   => 'shop_order', // WC orders post type
                                'post_status' => 'wc-completed' // Only orders with status "completed"
                            ));

    // // Foreach
    foreach ( $customer_orders as $customer_order ) {

        // Updated compatibility with WooCommerce 3+
        $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
        $order = wc_get_order( $customer_order );

        // Iterating through each current customer products bought in the order
        foreach ($order->get_items() as $item) {
            // WC 3+ compatibility
            if ( version_compare( WC_VERSION, '3.0', '<' ) ) 
                $product_id = $item['product_id'];
            else
                $product_id = $item->get_product_id();

            // Your condition related to your 2 specific products Ids
            if ( in_array( $product_id, $prod_arr ) ) 
                $bought = true;
        }
    }
    // return "true" if one the specifics products have been bought before by customer
    return $bought;
}

I’m running this function from:

add_action(‘wp_head’, ‘coldstream_head’, 1);

So, I’m guessing it’s being called too early from wp_head, but this somewhat doesn’t make sense after playing with it forever. I’d love a second set of eyes here…
