htmlspecialchars() expects parameter 1 to be string, array given laravel

Question

I'm trying to short records(tours) according to price (high to low and low to high) in search page, with a form that has submits on change event. Below is the code for the form:

{!!Form::open(['route' => 'short','method' => 'GET', 'role' => 'search','class'=>'select-filters'])!!}
    <input type="hidden" name="country" value="{{$country}}">
    <input type="hidden" name="category" value="{{$category}}">
    <input type="hidden" name="days" value="{{$days}}">
    <select name="sort_price" id="sort-price"  onchange="this.form.submit()">
    <option value="" selected="">Sort by price</option>
    <option value="lower">Lowest price</option>
    <option value="higher">Highest price</option>
    </select>
{!! Form::close() !!}

and I've initialized the values in the same page but give the error htmlspecialchars() expects parameter 1 to be string, array given:

@if(Request::only('country') != null)
    {{$country = Request::only('country')}}
@else
    {{ $country = null }}
@endif
@if(Request::only('category') != null)
    {{$category = Request::only('category')}}
@else
    {{ $category = null }}
@endif
@if(Request::only('days') != null)
    {{$days = Request::only('days')}}
@else
    {{ $days = null }}
@endif

The values in Request::only() is being passed from the search form in index page. When I die and dump:

{{dd(Request::only('country','category','days'))}}

I throws the incoming value in array form

It dumps individual key value pair if i pass only one argument:

    {{dd(Request::only('country'))}}

or

        {{dd(Request::only('category'))}}

or

        {{dd(Request::only('days'))}}

your name attributes without double quote!

only() always returns an array, so to get a string do this:

{{ request('country') }}

Instead of this:

{{ Request::only('country') }}
