This module defines the "money" CCK field. It uses the Currency API, which is included in the Currency module, to get a list of valid currencies.

Code

function money_field($op, &$node, $field, &$items, $teaser, $page) {
  switch ($op) {
    case 'validate':
      $allowed_currencies = _money_parse_currencies($field['allowed_currencies']);
      if (is_array($items)) {
        foreach ($items as $delta => $item) {

          // Generate the regular expression to validate the entered amounts.
          $decimal_separator = preg_quote(_money_get_decimal_separator($field['decimal_separator']));
          $digit_group_separator = preg_quote(_money_get_digit_group_separator($field['digit_group_separator']));
          $regexp = "/^-?(((\\d{1,3}" . $digit_group_separator . ")?(\\d{3}" . $digit_group_separator . ")*(\\d{3}){1})|\\d+)(" . $decimal_separator . "\\d{1,2})?\$/";

          // Validate the currency.
          if (!in_array($item['currency'], $allowed_currencies)) {
            form_set_error($field['field_name'] . '][' . $delta . '][currency', t('The currency %currency is not allowed.', array(
              '%currency' => t($item['currency']),
            )));
          }

          // Validate the amount:
          // - allow empty value when the field is not required
          // - ensure the amount was entered according to the format
          if ($field['required'] && $item['amount'] == '') {
            form_set_error($field['field_name'] . '][' . $delta . '][amount', t('You did not enter an amount.'));
          }
          else {
            if (!empty($item['amount']) && !preg_match($regexp, $item['amount'])) {
              form_set_error($field['field_name'] . '][' . $delta . '][amount', t('The amount is formatted invalidly.'));
            }
          }
