A handler to provide a field that is completely customizable by the administrator.

Code

function options_form(&$form, &$form_state) {
  parent::options_form($form, $form_state);

  // Get a list of the available fields and arguments for token replacement.
  $options = array();
  $fields = array(

    // We only use fields up to (and including) this one.
    if ($field == $this->options['id']) {
      break;
    }

    // If the instance has a custom name use that or use the title.
    // This helps if the same field is used more than once.
