How to retrieve data according to date range from mysql database using ajax in laravel php?

Question

I am building a simple holiday management system which allows the user to perform CRUD operation and to retrieve data according to a date range . However my CRUD operation is working as expected. But I am not able to retrieve the data according to user selected date range from an ajax call . Also this is the very first application that am developing by using laravel framework as well as ajax. I hope someone here may identify the reason for the problem am having with my code and will be able to help me.

index.blade.php

 <div class="input-group input-daterange">
       <input type="text" name="from_date" id="from_date" readonly class="form-control">
       <div class="input-group-addon to-text"> to </div>
       <input type="text"  name="to_date" id="to_date" readonly class="form-control">
 </div>

ajax request handler method in HolidayController.php

    public function fetch_data(Request $request)
    {
        if($request->ajax()) {
            if($request->from_date != '' && $request->to_date != '') {
                $data = DB::table('holidays')
                    ->whereBetween('startdate', 
                    array($request->from_date, $request->to_date))
                    ->get();
            }
            else {
                $data = DB::table('holidays')->orderBy('startdate', 'desc')
                ->get();
            }
            echo json_encode($data);

        }
    }

web.php

<?php

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::Resource('holiday', 'HolidayController');

make ajax request from custom_script.js

$(document).ready(function() {


    var date = new Date();

    $('.input-daterange').datepicker( {
        todayBtn: 'linked',
        format: 'yyyy-mm-dd',
        autoclose: true
    });

    var _token = $('input[name="_token"]').val();

    fetch_data();

    function fetch_data(from_date = '', to_date = '') {
        $.ajax({
            url:"{{ route('holiday.fetch_data')}}",
            method:"POST",
            data:{
                from_date:from_date, to_date:to_date, _token:_token
            },
            dataType:"json",
            success:function(data) {
                var output = '';
                $('#total_records').text(data.length);
                for(var count = 0; count < data.length; count++) {
                    output += '<tr>';
                    output += '<td>' + data[count].id + '</td>';
                    output += '<td>' + data[count].firstname + '</td>';
                    output += '<td>' + data[count].lastname + '</td>';
                    output += '<td>' + data[count].startdate + '</td>';
                    output += '<td>' + data[count].enddate + '</td></tr>';
                }
                $('tbody').html(output);
            }
        })
    }

    $('#filter').click(function() {
        var from_date = $('#from_date').val();
        var to_date = $('#to_date').val();
        if(from_date != '' && to_date != '') {
            fetch_data(from_date, to_date);
        }
        else {
            alert('Both Date is required');
        }
    });

    $('#refresh').click(function() {
        $('#from_date').val('');
        $('#to_date').val('');
        fetch_data();
    });

});

There is no problem with query ,unless $request->ajax() might remove for now. And change your blade file as follows, input type should be date , not text and remove readonly attribute.

<input type="date" name="from_date" id="from_date" class="form-control">
   <div class="input-group-addon to-text"> to </div>
<input type="date"  name="to_date" id="to_date" class="form-control">

And make sure that date data is valid data with database

For demonstration

 $(document).ready(function() { function fetch_data(from_date = '', to_date = '') { if(from_date != '' && to_date != '') { console.log(from_date+' | '+to_date) } } $('#filter').click(function() { var from_date = $('#from_date').val(); var to_date = $('#to_date').val(); if(from_date != '' && to_date != '') { fetch_data(from_date, to_date); } else { alert('Both Date is required'); } }); $('#refresh').click(function() { $('#from_date').val(''); $('#to_date').val(''); fetch_data(); }); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="input-group input-daterange"> <input type="date" name="from_date" id="from_date" class="form-control"> <div class="input-group-addon to-text"> to </div> <input type="date" name="to_date" id="to_date" class="form-control"> <button id="filter">filter</button> <button id="refresh">refresh</button> </div>

1. First of all, you can't use {{ route('holiday.fetch_data')}} inside your .js file . Use the simple route by typing the url or somehow, retrieve route from .blade.php file into .js file. eg using data-* attributes.

in #filter element pass the route with date-route="{{ route('holiday.fetch_data') }}"

and afterwards, in $('#filter').click(function() do

var route = $(this).data('route');

2. Please make sure your ajax request reach in your fetch_data in your Controller. In order to do that, just write inside your fetch_data

dd($request->all());

If you get the requests from ajax, means that your connections with fetch_data work just fine.

3. Try parsing the dates with Carbon , as I'm doing right below. Also, remove $request->ajax() and return json data with return .

use Carbon\Carbon;

public function fetch_data(Request $request)
{     
   if($request->from_date != '' && $request->to_date != '') {
        $from = Carbon::parse($request->from_date)->toDateString();
        $to = Carbon::parse($request->to_date)->toDateString();

       $data = DB::table('holidays')->whereBetween('startdate',[$from, $to])->get();
   }else {
       $data = DB::table('holidays')->orderBy('startdate', 'desc')->get();
   }

   return json_encode($data);
}
