  1. You can use the following code:

    // Add custom column headers here
add_action('woocommerce_admin_order_item_headers', 'my_woocommerce_admin_order_item_headers');
function my_woocommerce_admin_order_item_headers() {
    // set the column name
    $column_name = 'Test Column';

    // display the column name
    echo '<th>' . $column_name . '</th>';
}

// Add custom column values here
add_action('woocommerce_admin_order_item_values', 'my_woocommerce_admin_order_item_values', 10, 3);
function my_woocommerce_admin_order_item_values($_product, $item, $item_id = null) {
    // get the post meta value from the associated product
    $value = get_post_meta($_product->post->ID, '_custom_field_name', 1);

    // display the value
    echo '<td>' . $value . '</td>';
}

    I’ve commented it so it should be clear enough, but in a nutshell this code adds a custom column, named “Test Column”, and this column pulls the value from the custom field of the product, called “_custom_field_name”.

  2. Since WooCommerce 3.0 you are not allowed to call the product_id directly. You need to replace this:

    $product_id = $_product->get_id();
$value = get_post_meta($product_id, '_custom_field_name', 1);

    This will do the trick and remove all errors and notices.
