fullcalendar json is not working - fullcalendar

Question

I am having a hardtime trying to populate events on fullcalendar, following is my code, trying to fetch data from mysql
class mycalendarleaves extends Generic{
function calendar_LeaveDetails(){
$year = date('Y');
$month = date('m');
$this->user_id = $_SESSION['user_id'];
$params = array( ':user_id' => $this->user_id );
$stmt = parent::query("SELECT * FROM messages WHERE TYPE = 'leave' AND leave_status='approved' AND sender_id = :user_id;", $params);
while($value = $stmt->fetch()) :
$_SESSION['cal_data'] = array(
'id' => $value['id'],
'title' => $value['sender_name'],
'start' => "$year-$month-10"
);
endwhile;
}
}
echo json_encode($_SESSION['cal_data']);
$mycalendarleaves = new mycalendarleaves();
here is the script
<script type='text/javascript'>
$(document).ready(function() {
$('#calendar').fullCalendar({
editable: true,
events: "calendar.php",
eventDrop: function(event, delta) {
alert(event.title + ' was moved ' + delta + ' days\n' +
'(should probably update your database)');
},
loading: function(bool) {
if (bool) $('#loading').show();
else $('#loading').hide();
}
});
});
I dont get any error, the calendar still appears blank without data. what am i doing wrong?

I got it to work, incase someone else is having a problem may be this will help them as well.
following is my function that is fetching data from mysql
function calendar_EventDetails(){
$year = date('Y');
$month = date('m');
$this->id = $_SESSION['id'];
$params = array( ':id' => $this->id );
$stmt = parent::query("SELECT * FROM TABLENAME WHERE TYPE = 'event' AND status='approved' AND id = :id;", $params);
unset($_SESSION['events']);
while($value = $stmt->fetch()) :
$_SESSION['events'][] = array(
'id' => $value['id'],
'title' => $value['name'],
'start' => "$year-$month-10"
);
endwhile;
}
Following is the script which is calling the php file where the above function is placed
<script type='text/javascript'>
$(document).ready(function() {
$('#calendar').fullCalendar({
editable: true,
events: "calendar.php",
eventDrop: function(event, delta) {
alert(event.title + ' was moved ' + delta + ' days\n' +
'(should probably update your database)');
},
loading: function(bool) {
if (bool) $('#loading').show();
else $('#loading').hide();
}
});
});
