看到這段 Code 的時候真是有種喔原來有這些喔的感覺，趕快記錄下來。這些都是在 Action 裡面可以用的 method，重點是沒有查 API 誰會知道有這些可以用。[sfActions API]

class mymoduleActions extends sfActions
{
  public function executeIndex()
  {
    // Retrieving request parameters
    $password    = $this->getRequestParameter('password');

    // Retrieving controller information
    $moduleName  = $this->getModuleName();
    $actionName  = $this->getActionName();

    // Retrieving framework core objects
    $request     = $this->getRequest();
    $userSession = $this->getUser(); // 這個最不像
    $response    = $this->getResponse();
    $controller  = $this->getController();
    $context     = $this->getContext();

    // Setting action variables to pass information to the template
    $this->setVar('foo', 'bar');
    $this->foo = 'bar';            // Shorter version

  }
}

以上的 $this 如果在 Template 裡面要呼叫的話，記得使用 $sf_context 這個物件。
sfActions 的不同用法:

class mymoduleActions extends sfActions
{
  public function preExecute()
  {
    // The code inserted here is executed at the beginning of each action call
    ...
  }

  public function executeIndex()
  {
    ...
  }

  public function executeList()
  {
    ...
    $this->myCustomMethod();  // Methods of the action class are accessible
  }

  public function postExecute()
  {
    // The code inserted here is executed at the end of each action call
    ...
  }

  protected function myCustomMethod()
  {
    // You can also add your own methods, as long as they don't start with "execute"
    // In that case, it's better to declare them as protected or private
    ...
  }
}

File Upload 在 Symfony 下面非常簡單就解決，想想看如果指有用 php 寫處理個檔案上傳要寫幾行？

class mymoduleActions extends sfActions
{
  public function executeUpload()
  {
    if ($this->getRequest()->hasFiles())
    {
      foreach ($this->getRequest()->getFileNames() as $fileName)
      {
        $fileSize  = $this->getRequest()->getFileSize($fileName);
        $fileType  = $this->getRequest()->getFileType($fileName);
        $fileError = $this->getRequest()->hasFileError($fileName);
        $uploadDir = sfConfig::get('sf_upload_dir');
        $this->getRequest()->moveFile('file', $uploadDir.'/'.$fileName);
      }
    }
  }
}
