Link to append parameter to current query in URL

I once watched a video on the site about the following but can't seem to find it anywhere.

I have a form which is used to search by subject and postcode. The form makes a get request and the url then looks like:

Now I want to add a link to append another query, say within=10 to look like this:

I have two questions:

How do I use a link to reload the page but add a parameter while not loosing the old ones.
How do I use str_slug to make the url prettier (currently subjects[] is encoded as subjects%5B%5D

Thank you for your time! I'm happy to be pointed to a discussion or video!

Thank you for your reply, but I can't add a hidden field as I want it to be a link like Jeffrey uses to filter lessons say.
You're probably right, but the devil is in the detail?

Would be nice to have subject=piano&subject=guitar

You cant have what you want it would erase piano value with guitar.

Route::get('/search', ['as' => 'search', 'uses' => 'SomeController@search']);

route('search', ['subject' => ['piano', 'guitar'], 'other_value' => 'whatever']);

Thank you! That worked :)

{!! link_to_route('search', 'Within 10 miles', ['subject' =>Input::get('subjects'), 'postcode' => Input::get('postcode'), 'within' => '10'] ) !!}

Is it ok to use Input::get() in a view?

This is what I went with in the end:

 {!! link_to_route('search', 'Link', array_merge(Request::all(), ['anything'=>'else'])) !!}

Very simple method, when not using laravel collective html

<p>Already signed up? <a href="{{ route('login', array_merge(request()->all())) }}">Log in</a>  </p>
