How to pass a variable to datepicker

@ksi Thank you my friend for your support I have a few questions.

should I set the $from and $to variable to be empty like this:

 $from = date('');
 $to = date('');

when I set the dates while inspecting the page, the console doesn't show anything, if you noticed I have a search button, how can I make it execute the script?

My Controller and view after modifications:

Controller:

<?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use Gate;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Symfony\Component\HttpFoundation\Response;

class VouchersAccountingController extends Controller
{
    public function index()
    {
        abort_if(Gate::denies('vouchers_accounting_access'), Response::HTTP_FORBIDDEN, '403 Forbidden');

        $from = date('');
        $to = date('');

        $Reports = DB::table('create_vouchers')
            ->select('create_vouchers.id', 'client_name', 'night', 'hotels.hotel_name', 'arrivaldate', 'departuredate', 'total_amount', 'number_of_room', 'payment_mode')
            ->join('hotels', 'hotels.id', 'create_vouchers.hotel_name_id')
            ->whereBetween('arrivaldate', [$from, $to])->get();


        //return view('admin.vouchersAccountings.index', compact(['Reports']));
        // send from & to to the view
        return view('admin.vouchersAccountings.index', compact('Reports', 'from', 'to'));
    }
}

@tzak9022 you set those variables to whatever you want them to be. Probably you want them to be populated from the request

@ksi yes thats what im talking about how to populate them from the request through the script?
