Answer 1

You should create a select of your users and do something like this

$('#users').on('change', function() {
    var userId = this.value;

    $('#calendar-holder').fullCalendar({ 
        eventSources: [{
            url: "{{ path('fullcalendar_load_events') }}",
            type: 'POST',
            data:  {
                filters: {
                    user_id: userId,
                }
            },
            error: function () {
                alert('There was an error while fetching FullCalendar!');
            }
        }]
    });
    $('#calendar-holder').fullCalendar('refetchEvents');
});

in your listener you can now update the query accordingly

$bookings = $this->em->getRepository(Booking::class)
    ->createQueryBuilder('booking')
    ->where('booking.beginAt BETWEEN :startDate and :endDate')
    ->innerJoin('booking.user', 'user')
    ->andWhere('user.id = :userId')
    ->setParameter('userId', $filters['user_id'])
    ->setParameter('startDate', $startDate->format('Y-m-d H:i:s'))
    ->setParameter('endDate', $endDate->format('Y-m-d H:i:s'))
    ->getQuery()->getResult();
