Can I pass a view's exposed filter values to the next page?

Question

I have a D8 site view with exposed filters. I want the selected filters from that view to carry over to the next page's URL.

For example: The page lists software titles. If someone filters on OS, and picks MacOS, the URL of the view page changes from "viewpage" to "viewpage?os=MacOS". I want to make the links in the view change from "drupalpage" to "drupalpage?os=MacOS".

I can't figure out how to add the "?os=MacOS" query string to a link in the view. Is there a way to do that?

Answer 1

I think what you needed to get in on your preprocess and pass it to your views.

In a hook_preprocess_views_view() implementation in your theme or module:

$values = $view->getExposedInput();
// for example $values["os"];

Or, you can access the values directly from the views-view.html.twig template:

// Assuming `os` is configured to be the Filter identifier in the 

// view's Filter Criteria exposed filter.
{{ view.getExposedInput.os }}
