Redirect to current URL while changing a query parameter in Laravel

Question

Is there a built-in way to do something like this?

Let's say I have a search-page that has a few parameters in the URL:

example.com/search?term=foo&type=user

A link on that page would redirect to an URL where type is link. I'm looking for a method to do this without manually constructing the URL.

Edit:
I could build the URL manually like so:

$qs = http_build_query(array(
    'term' => Input::get('term'),
    'type' => Input::get('type')
));
$url = URL::to('search?'.$qs);

However, what I wanted to know is if there is a nicer, built-in way of doing this in Laravel, because the code gets messier when I want to change one of those values.

Giving the URL generator a second argument ($parameters) adds them to the URL as segments, not in the query string.

Answer 1

You can use the URL Generator to accomplish this. Assuming that search is a named route:

$queryToAdd = array('type' => 'user');
$currentQuery = Input::query();

// Merge our new query parameters into the current query string
$query = array_merge($queryToAdd, $currentQuery);

// Redirect to our route with the new query string
return Redirect::route('search', $query);

Laravel will take the positional parameters out of the passed array (which doesn't seem to apply to this scenario), and append the rest as a query string to the generated URL.
