Symfony validators, widgets for backend

I use symfony 1.4.8 . I add ReCaptcha to my form , using SfExtraFormPlugin. I have widget and validator for it in my " public function configure() "

....     
$this->widgetSchema['captcha'] = new sfWidgetFormReCaptcha(array(
      'public_key' => sfConfig::get('app_recaptcha_public_key')
    ));


$this->validatorSchema['captcha'] = new sfValidatorReCaptcha(array(
      'private_key' => sfConfig::get('app_recaptcha_private_key')
    ));
...

I also have bac开发者_C百科kend app , and my "public function configure()" for it :

 public function configure()
  {
    parent::configure();
....
}

So when I want to add post from my backend I have an error:The item has not been saved due to some errors. Is there a way to remove widget and validators for ReCaptcha only to my backend? Now I see only one way, it is to remove

parent::configure();

and write all widget and validators to backend separately from the frontend widget and validators.. :( p.s Sorry for my bad English p.p.s Thank you in advance for your answers ;-)

Add an option to your form. When you instantiate it, you should know if you're on the backend or the frontend.

// in your actions.class.php
$this->form = new MyForm(null, array('from_backend' => true)); // or false...

// in your form
if (!$this->getOption('from_backend'))
{
  // add the recaptcha widget and validator...
}

It should work :)

I find second way :

if ( sfConfig::get('sf_app') == "frontend" )
{
   widget and validator
}
elseif ( sfConfig::get('sf_app') == "backend" )
{
   widget and validator
}
