Add help link to send module links

Hi-

I wanted the option of having a help link on the links that send modules create. I added this code to send.inc in _send_settings_form()

$form['send_link_settings'] = array(
    '#type'          => 'fieldset',
    '#title'         => 'Link settings',
  );

  $form['send_link_settings']["{$module}{$type}_linktext"] = array(
    '#type'          => 'textfield',
    '#title'         => t("Link text"),
    '#default_value' => _send_value('linktext', $module, $nodetype, $node),
    '#size'          => 30,
    '#maxsize'       => 100,
    '#description'   => t('Leave blank to suppress link'),
  );

  $form['send_link_settings']["{$module}{$type}_linktext_help_display"] = array(
    '#type'            => 'checkbox', 
    '#title'           => t('Display help link.'),
    '#default_value'   => _send_value('linktext_help_display', $module, $nodetype, $node),
    '#description'     => t('When this is enabled, the text below will be displayed in line with the link.'),
  );
  $form['send_link_settings']["{$module}{$type}_linktext_help_text"] = array(
    '#type'            => 'textarea',
    '#title'           => t('Guest pass help text'),
    '#default_value'   => _send_value('linktext_help_text', $module, $nodetype, $node ),
    '#description'     => t("This text is appended to the link on pages where it is displayed."),
  );

in send.module, in function send_link(), i modified the function to look like this:

function send_link($type, $node=null) {
  if (!$node) return;
  foreach(_send_modules() as $m) {
    $on = variable_get("{$m}_{$node->type}", 0) && module_invoke($m, 'send', 'access', $m);
    if ($on && $linktext = _send_value('linktext', $m, $node->type, $node)) {
      // check if there is help text, if so, append it to the link
      if (_send_value('linktext_help_display', $m, $node->type, $node)) { 
         $append = _send_value('linktext_help_text', $m, $node->type, $node); 
      } else { $append = null; }
      $links[] = l($linktext, "send/{$m}/{$node->nid}", array("class" => 'send-link send-'.$m) ) . $append; 
    }
  }
  return $links;
}
