不能包括drupal_get_form

Question

我有drupal 6模块，我尝试将手册升级到drupal 7，我尝试加载另一个用drupal_get_form显示表单的功能但没有发生任何事情，

这是代码

function page_dashboard_penjualan() {
  global $user;

  $rid=db_query("select rid from users_roles where uid = '$user->uid'")->fetchAssoc();
  //$rid = db_select('users_roles','rid')
  //->fields('rid')
  //->condition('uid',$user->uid)
  //->execute()
  //->fetchAssoc();

  if($user->uid=="1" or $rid->rid=="32"){
        module_load_include('modules', 'display_ket', 'modules/product/display_ket/display_ket.module'); 
    $output = drupal_get_form('findlstappkr_dashboard');
        $output = tabel_dashboard_penjualan();

  } else {
    $output = "Maaf, Halaman ini hanya bisa diakses oleh bagian Penjualan";
  }
  return $output;
}
