Symfony: pass parameter between actions (with a redirect)

问题

I am redirecting from one action (executeProcess) to another (executeIndex). I want to be able to pass a parameter/variable along, without using GET (e.g. $this->redirect('index', array('example'=>'true')))

Is there a way I can directly pass parameters without having it directly displayed in the URL? (e.g. POST). thanks.

Why dont you use sessions to store values before redirecting, and then getting them on the other action after you redirected? like:

class ActionClass1 extendes sfActions
{
  public function executeAction1(sfWebRequest $request)
  {
    [..]//Do Some stuff
    $this->getUser()->setAttribute('var',$variable1);
    $this->redirect('another_module/action2');
  }
}

class ActionClass2 extends sfActions
{
  public function executeAction2(sfWebRequest $request)
  {
    $this->other_action_var = $this->getUser()->getAttribute('var');
    //Now we need to remove it so this dont create any inconsistence
    //regarding user navigation
    $this->getUser()->getAttributeHolder()->remove('var');
    [...]//Do some stuff
  }
}

The best way of passing a variable between two Actions is by using FlashBag

public function fooAction() {
    $this->get('session')->getFlashBag()->add('baz', 'Some variable');
    return $this->redirect(/*Your Redirect Code to barAction*/);
}

public function barAction() {
    $baz = $this->get('session')->getFlashBag()->get('baz');
}

To use the variable in Twig template use this --

{% for flashVar in app.session.flashbag.get('baz') %}
    {{ flashVar }}
{% endfor %}

Another solution that does not redirect the browser

class someActionClass extends sfActions{
  function myExecute(){
    $this->getRequest()->setParameter('myvar', 'myval');
    $this->forward('mymodule', 'myaction')
  }
}


//Here are your actions in another module

class someActionClass2 extends sfActions{
  function myExecute2(){

    $myvar = $this->getRequest()->getParameter('myvar');

  }
}
