FullCalendar and json events - php

Question

I try to make availability calendar with FullCalendar.js. Everything works fine if I call events from database in my index.php, but when I try to get events via json I get nothing. Calendar is showing but normally, but not showing events. When I look in smjestaj-rezervacija-kalendar.php I get:
[ { title: 'Rezervirano', start: '2015-01-30', allDay: true } , { title: 'Rezervirano', start: '2015-01-31', allDay: true } , { title: 'Rezervirano', start: '2015-02-01', allDay: true } ]
so it works. Anyone having idea why it doesn't show on calendar, what am I doing wrong?
index.php
<script type="text/javascript">
$(document).ready(function(){
// Event calendar js
try{
$('#utopia-fullcalendar-2').fullCalendar({
header:{
left:'prev,next',
center:'title',
right:''
},
dayNames: ['Nedjelja','Ponedjeljak','Utorak','Srijeda','Četvrtak','Petak','Subota'],
dayNamesShort: ['Ned','Pon','Uto','Sri','Čet','Pet','Sub'],
monthNames: ['Siječanj','Veljača','Ožujak','Travanj','Svibanj','Lipanj','Srpanj','Kolovoz','Rujan','Listopad','Studeni','Prosinac'],
monthNamesShort: ['Sij','Velj','Ožu','Tra','Svi','Lip','Srp','Kol','Ruj','Lis','Stu','Pro'],
firstDay:1,
editable:false,
height:540,
events: 'smjestaj-rezervacija-kalendar.php?SmjestajID=<?=$_GET['SmjestajID'];?>'
});
} catch (e){
errorMessage(e);
}
});
</script>
and here is my smjestaj-rezervacija-kalendar.php:
<?php
header('Content-type: text/json; charset=utf-8');
include($_SERVER['DOCUMENT_ROOT']."/admin/config.php");
echo '[';
$SmjestajID = $_GET['SmjestajID'];
$rezultat_kalendar = mysqli_query($link, "SELECT * FROM smjestaj_kalendar WHERE KalendarSmjestaj=$SmjestajID ORDER BY KalendarID ASC");
$broj_unosa = mysqli_num_rows($rezultat_kalendar);
$i = 1;
while ($redak_kalendar = mysqli_fetch_array($rezultat_kalendar))
{ ?> {
title: 'Rezervirano',
start: '<?=$redak_kalendar['KalendarDatum']?>',
allDay: true
}
<?php
if ($i <> $broj_unosa){
echo ',';
}
$i ++;
}
echo ']';
?>
I try with http://fajitanachos.com/Fullcalendar-and-recurring-events/ json file, but still get nothing.

Answer 1

I googled and find that in json should be no html object, so I remove header('Content-type: text/json; charset=utf-8'); and go with array instead of html. This answer was helpfull: How do I get FullCalendar to display information from my JSON feed?
<?php
include($_SERVER['DOCUMENT_ROOT']."/admin/config.php");
$SmjestajID = $_GET['SmjestajID'];
$rezultat_kalendar = mysqli_query($link, "SELECT * FROM smjestaj_kalendar WHERE KalendarSmjestaj=$SmjestajID ORDER BY KalendarID ASC");
while ($record = mysqli_fetch_array($rezultat_kalendar)) {
$event_array[] = array(
'id' => $record['KalendarID'],
'title' => "Rezervirano",
'start' => $record['KalendarDatum'],
'allDay' => true
);
}
echo json_encode($event_array);
?>
