Creating custom tokens with Drupal Commerce order information

One thing I found lacking with Drupal Commerce was the lack of tokens with line-item level data. I wanted to send an email via Rules to the site’s managers with order/product information (no billing of course). There was nothing that listed product/line items. Here is what I used to get what I needed.

You will see some custom formatting I have in place that creates an output string. These tokens will then be accessible in Rules in other areas that use tokens.

/**
* Implements hook_token_info_alter().
*/
function mymodule_token_info_alter(&$info) {
  $info['tokens']['commerce-order']['billing-details'] = array(
    'name' => t('Billing Details token'),
    'description' => t('Custom billing details token.'),
  );
  $info['tokens']['commerce-order']['product-details'] = array(
    'name' => t('Product Details token'),
    'description' => t('Custom product details token.'),
  );
}

/**
* Implements hook_tokens().
*/
function mymodule_tokens($type, $tokens, array $data = array(), array $options = array()) {
  $url_options = array('absolute' => TRUE);
  if (isset($options['language'])) {
    $url_options['language'] = $options['language'];
    $language_code = $options['language']->language;
  }
  else {
    $language_code = NULL;
  }
  $sanitize = !empty($options['sanitize']);
  $replacements = array();
  if ($type == 'commerce-order' && !empty($data['commerce-order'])) {
    // get order details
    $order = $data['commerce-order'];
    $profile = commerce_customer_profile_load($order->commerce_customer_billing[LANGUAGE_NONE][0]['profile_id']);
    $customer = $profile->commerce_customer_address[LANGUAGE_NONE][0];
    $total = $order->commerce_order_total[LANGUAGE_NONE][0]['amount'] . $order->commerce_order_total[LANGUAGE_NONE][0]['currency_code'];
    foreach ($order->commerce_line_items[LANGUAGE_NONE] as $line_item) {
      $items[] = commerce_line_item_load($line_item['line_item_id']);
    }
    // add output to tokens
    foreach ($tokens as $name => $original) {
      switch ($name) {
        case 'billing-details':
          $replacements[$original] = $customer['name_line'] . "\n" . $customer['thoroughfare'] . "\n" . $customer['premise'] . "\n" . $customer['locality'] . ', ' . $customer['administrative_area'] . ' ' . $customer['postal_code'] . "\n\n";
          break;
        case 'product-details':
          $output = '';
          foreach ($items as $item) {
            $output .= number_format($item->quantity) . ' ' . $item->line_item_label . ' - ' . $item->commerce_total[LANGUAGE_NONE][0]['amount'] . $item->commerce_total[LANGUAGE_NONE][0]['currency_code'] . "\n";
          }
          $replacements[$original] = $output . "\nOrder total: " . $total . "\n";
          break;
      }
    }
  }
  return $replacements;
}
