How to get the referer url in symfony redirection

Question

I'm using symfony 1.4 for some web application. In there when someone try to access one action I'm redirecting it to a new action as follows.

//Assume I'm redecting from module1/action1 to module2/action2
$this->redirect('module2/action2');

I in the module2/action2 can I get the url where it get redirected. I used

$request->getReferer();

But it doesn't give any result.

I don't need to use forward instead of redirect because it doesn't match for my need. Can someone help me on this.

Solution

I can suggest you to put the referer inside the session to be able to retrieve after your redirect. This how sfGuard perform it.

Before your redirect:

// save the referer
$referer = $this->getContext()->getActionStack()->getSize() > 1 ? $request->getUri() : $request->getReferer();
$this->getUser()->setAttribute('referer', $referer);

// make your redirect
$this->redirect('module2/action2');

Then, in your module2/action2, retrieve your referer like that:

$referer = $this->getUser()->getAttribute('referer');

// finally, remove it from session
$this->getUser()->getAttributeHolder()->remove('referer');

So where do we need to do this. Is it at a filter or somewhere.

Nope, you can put every thing in your action

[Thilanka]

Yes but then every action we have to put. It won't be a generic place where we can refer.

extend your controller by a custom one where yo put this
