In Symfony2 how do I redirect within a Controller to a URL with an anchor tag/hash

问题

I'm in a Controller and I want to redirect back to a URL, say /home/news/example#comment1423

How can I add the hash in to the return params?

return $this->redirect(
    $this->generateUrl("news_view", array("permalink" => "example"))
);

回答1:

The simplest solution would probably be concatenation:

$url = $this->generateUrl("news_view", array("permalink" => "example"));
return $this->redirect(
    sprintf('%s#%s', $url, 'comment1423')
);

回答2:

In Symfony 3.2 you can do this:

// generating a URL with a fragment (/settings#password)
$this->redirectToRoute('user_settings', ['_fragment' => 'password']);
