I have a scenario where the user clicks on a link received to an email which requires a sign in. if the link is http://test.url.com/product/2, the user should sign in and the page should redirect to the same path after authentication.

I tried to tackle this via the use of print_r($request->headers->get('referer')); which posted a question here : Redirect to the url of the clicked (referred) link . which was unsuccessful as it returned null.

My next aim is to pass parameters to the sign in page depending on the url.

eg: if the user clicks http://test.url.com/product/2, the sign in url would look like http://test.url.com/signin/product/2 or http://test.url.com/signing?=pruduct?2 or something like that where the system would redirect the user to the desired page.

Any document/ example on passing parameters from the config level is greatly appreciated as I am very new to this domain. thanks :)

  • Save the url in the cookie, and after authentication, redirect him – Cristian Bujoreanu Jan 12 '15 at 09:14
  • @CristianBujoreanu thank you very much for the reply. I will try this :) but is this the best way to do it? I am asking just to clarify as I am new to this field – Hasitha Shan Jan 12 '15 at 09:15
  • If your authentication process has more steps, can't use $request->headers->get('referer') anymore, so cookie solution would be very good, why not (don't forget to delete url from cookie). – Cristian Bujoreanu Jan 12 '15 at 09:18
  • @CristianBujoreanu thanks for that information :) i will try this and let you know (y) – Hasitha Shan Jan 12 '15 at 09:19

I would suggest to mention the redirect url as a query string on the login url like

http://test.url.com/signin/?redirect=http://test.url.com/product/2

Upon a successful login all you have to do is 

$url=$_GET['redirect'];
header("location:".$url);

  • Hi, this method is great. just one thing, how can I access the current url of the page so that I can attach it to the `login_path: http://test.url.com/signin/?redirect=` in `security.yml`? thank you..i tried searching but ended up empty handed – Hasitha Shan Jan 12 '15 at 06:08

Does this helps you?

public function productAction($id, Request $request){
    $url = $this->container->get("router")->generate("product_route", array("id" => $id));

    /** @var $session Session */
    $session = $request->getSession();
    $session->set("redirect_url", $url);
}         

public function signinAction(Request $request){
    // do your stuff

    /** @var $session Session */
    $session = $request->getSession();
    if ($session->has("redirect_url")){
        return new RedirectResponse($session->get("redirect_url");
    }
}

  • Hi, as the redirection happens the application never reach a controller. so I must get the current url info within the security.yml or other suited yml files :) if this possible. – Hasitha Shan Jan 13 '15 at 04:18
