[FIXED] How to get the record if Count is zero in Laravel


Im using Chart.js to show the number of bookings for each month. This is my query. It is working fine.
My problem is if there is no booking in a month then it doesnt show anything. No zero value. On the chart i get the value like

  • January 23
  • February 34
  • April 23
  • May 25
  • July 42

March and June are shown on the chart..How can i get the value Zero for months where there is no booking..

$graph = DB::table('bookings')
    ->select(DB::raw('MONTHNAME(created_at) as month'), DB::raw("DATE_FORMAT(created_At,'%M %Y') as monthNum"),    DB::raw('count(*) as totalbook'))
    ->orderBy('created_at', 'asc')

To get months,`

@foreach ($graph as $dat) 
                "{!! $dat->monthNum !!}",

And to get booking numbers

@foreach ($graph as $dat) 
                {!! $dat->totalbook !!},


MySQL will not fill in the months that aren’t available, it will simply group by what you have available and then give you those results.

What you could do is use DatePeriod and Laravel’s Collection class:

$results = DB::table('bookings')
    ->selectRaw("DATE_FORMAT(created_At,'%Y-%m-01') as monthNum, count(*) as totalbook")

$results = collect($results)->keyBy('monthNum')->map(function ($item) {
    $item->monthNum = \Carbon\Carbon::parse($item->monthNum);

    return $item;

$periods = new DatePeriod($results->min('monthNum'), \Carbon\CarbonInterval::month(), $results->max('monthNum')->addMonth());

$graph = array_map(function ($period) use ($results) {

    $month = $period->format('Y-m-d');

    return (object)[
        'monthNum'  => $period->format('M Y'),
        'totalbook' => $results->has($month) ? $results->get($month)->totalbook : 0,

}, iterator_to_array($periods));

Please note I have updated monthNum in the query as it will be reformatted later.

Also, you should need to use the blade raw tags ({!! !!}) for this as {{ $dat->totalbook }} should work absolutely fine.

Hope this helps!
