Hi,


Just call the sfGuardSecurityUser::signIn with an extra parameter :

  $user = sfGuardUserPeer::retrieveByUsername($email);



  // Please note the use of "instanceof" in the condition

  if ( $user instanceof sfGuardUser ) 

  {

    $this->getUser()->signin( $user, true );  // TRUE means "remember me"

    $this->setFlash('notice', 'You are logged in');

    $this->forward('user', 'home');

    return sfView::SUCCESS;

  }

For more details, see sfGuardPlugin code source :
