Symfony : how to pass a variable between executeNew() and executeCreate()?

Question

under symfony/doctrine, i want to set to the form a value contained in an URL parameter

offer/registration/new?offer_id=23

  public function executeNew(sfWebRequest $request)
  {
    // echo $request->gerParameter('offer_id');
    // echoes 23

    $this->form = $this->configuration->getForm();
    $this->offer_registration = $this->form->getObject();
  }

  public function executeCreate(sfWebRequest $request)
  {
    // echo $request->gerParameter('offer_id');
    // echoes nothing

    $offer = new OfferRegistration();
    $offer->setOfferId($offer_id);
    $this->form = $this->configuration->getForm($offer);
    $this->offer_registration = $this->form->getObject();

    $this->processForm($request, $this->form);

    $this->setTemplate('new');
  } 

How to pass the $offer_id between executeNew() and executeCreate() so that i can set the right OfferId on the form ?

PS: I precise that i'm working with a admin backend module

You would need to pass a parameter when clicking on the NEW link. By default, the symfony generator does not pass any parameters when creating a NEW object.

In order to modify the link that is being generated, you will need to modify the template file that is created. The best way to do this, is to fetch it from your cache folder, and copy it into your /backend/modules/templates folder, and then modify that file.

More information on the admin generator template system can be found here

Once you find the file that generates the Create New link, you can then modify that link to add a parameter.
