Filter FullCalendar and DataTables

This guide will provide an outline on integrating a set of input filters with an instance of FullCalendar and DataTables on the same page.

Filters

Don’t forget to add the `table-filters` class to your filter elements.

The filters are standard inputs, except these are not inside a form element, instead, this data will be sent via AJAX.

<div class="form-group">
    <label for='title'>{{ __('Title') }}</label>
    <input class="form-control table-filters" id='title' type="text" name="title" value="{{ old('title', request('title')) }}">
</div>

<div class="form-group">
    <label for='status_id'>{{ __('Status') }}</label>
    <select name="status_id" class="form-control select2Ajax table-filters" id="status_id" data-url="{{ route('admin.ajax.statuses.search') }}">
        <option value=""></option>
    </select>
</div>

FullCalendar setup

Here is a simplified example of our main initialisation for our FullCalendar instance.

const calendarElement = document.getElementById('calendar');
const bookingsCalendar = new FullCalendar.Calendar(calendarElement, {
    headerToolbar: {
      start: 'prev,next today',
      center: 'title',
      end: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
    },
    events: {
        url: '{{ route('admin.ajax.bookings.get-calendar') }}',
        method: 'GET',
        extraParams: function() {
            /*
              Here we will grab the values of each of our filter input
              These will then be sent to the server
            */
            return {
                title: $('[name="title"]').val(),
                status_id: $('[name="status_id"]').val(),
            };
        }
    },
});

DataTable setup

This is our simplified DataTable setup.

const bookingsTable = $('#bookings-table').DataTable({
  processing: true,
  serverSide: true,
  responsive: true,
  searching: false,
  ajax: {
      url: '{{ route('admin.ajax.bookings.get-table') }}',
      data: function(data) {
          // this is the equivalent of the 'extraParams' method used in FullCalendar
          data.title = $('[name="title"]').val();
          data.status_id = $('[name="status_id"]').val();
      }
  },
  columns: [
      { data: 'title' },
      { data: 'status' },
  ]
});

Listening for filter actions

Finally, we need to listen for updates on our filters, when we detect a change we will then manually reload the calendar and table with the updated data parameters.

$('.table-filters').on('change keyup', function() {
  bookingsTable.draw();
  bookingsCalendar.refetchEvents().render();
});
