Redirect user to previous page after registration

Question

I'd like users registering on my website are redirected to the page where they clicked the "create account" button which is in a modal.

First, I tried to redirect to an absolute url I tried

$form_state->setRedirect($myUrl);

I tried

$_REQUEST['destination'] = '<front>';

I tried this too :

$response = new \Drupal\Core\Routing\TrustedRedirectResponse('http://www.google.be');
$form_state->setResponse($response);

I'm always redirected to /user/[uid]/edit

Answer 1

You could use Rules module to achieve that..

Answer 2

You can accomplish this with the Rules Link module, and using the php variable php variables %server[HTTP_REFERER]

Or, without having to enable php in rules, you can use a custom 'previous page' token, explained in this drupal.org issue.

Create a rule that triggers when the link is clicked, stores the previous page a a variable, do some other actions you want and at the end a redirect action to that previous page variable.
