Using php array in fullCalendar

I used the latest javascript fullCalendar (https://fullcalendar.io/) on a wordpress webpage to be able to display appointments of a wordress my users. So far the Callendar shows up on the page. Now I want to get the appointments from the db and display them in the Calendar.
If I create an array in php, with the appointments to display as a string, the appoinment shows up in the calendar.
Example:
$events = $wpdb->get_results("SELECT * FROM wp_projekt_calendar WHERE calendar_author=$uid");
foreach($events AS $event){
$array['title']= 'rtrt';
$array['start']= '2020-08-10 10:00:00';
$array['end'] = '2020-08-10 11:00:00';
}
echo json_encode($array);
But if I use the query results to show the appointment it doesent work (query works well!):
foreach($events AS $event){
$array['title']= $event_array->calendar_title;
$array['start']= $event_array->calendar_startdate .' '.$event_array->calendar_starttime;
$array['end'] = $event_array->calendar_enddate .' '.$event_array->calendar_endtime;;
}
echo json_encode($array);
This is how my calendar looks like:
<script>
document.addEventListener('DOMContentLoaded', function() {
var initialLocaleCode = 'de';
var localeSelectorEl = document.getElementById('locale-selector');
var calendarEl = document.getElementById('calendar');
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
var calendar = new FullCalendar.Calendar(calendarEl, {
height: '100%',
expandRows: true,
headerToolbar: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
initialView: 'dayGridMonth',
locale: initialLocaleCode,
navLinks: true, // can click day/week names to navigate views
editable: true,
selectable: true,
nowIndicator: true,
dayMaxEvents: true, // allow "more" link when too many events
events: {
url: "https://mydomainxy.com/wp-content/themes/gambit-child/events.php?uid='<?php // $anwender_id ?>'",
//url: "https://mydomainxy.com/wp-content/themes/gambit-child/php/get-events.php'",
type: 'POST',
error: function() {
alert('There was an error while fetching events.');
}
}
});
calendar.render();
});
</script>
What am I doing wrong or how can I get this to work?

DateTime conversion from FullCalendar to Controller PHP

I'm using FullCalendar to display a calendar on the web page (no surprise there).
A user can add events on the calendar, which is then passed through POST to the CodeIgniter controller. The controller executes a function in the model to insert the data in the database.
The problem I'm facing is that the date time, when inserted in the database adds 4 minutes for a reason i do not understand.
This is the JavaScript used for FullCalendar:
$(document).ready(function() {
var today = moment().day();
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
center: 'title',
right: 'month,agendaWeek,agendaDay'
},
editable: true,
defaultView: 'agendaWeek',
eventLimit: true, // allow "more" link when too many events
selectable: true,
selectHelper: true,
select: function(start, end) {
var title = "<?=$anim['NOMANIM']?>";
var id = "<?=$anim['CODEANIM']?>";
if (title) {
start = moment(start).format('YYYY-MM-DD HH:mm:ss');
end = moment(end).format('YYYY-MM-DD HH:mm:ss');
$.ajax({
url: '<?php echo base_url("index.php/activite/add_activite"); ?>',
data: 'title='+ title+'&id='+ id+'&start='+ start +'&end='+ end,
type: "POST",
success: function(json) {
alert(start); // THIS SHOWS THE CORRECT DATETIME
}
})
};
$('#calendar').fullCalendar('renderEvent',
{
title: title,
start: start,
end: end,
}, true); // stick? = true
$('#calendar').fullCalendar('unselect');
},
events: <?=$events?>
});
});
And here is the controller function:
public function add_activite() {
$title = $_POST['title'];
$id = $_POST['id'];
$datetime_start = strtotime($_POST['start']);
$datetime_end = strtotime($_POST['end']);
$date = date('Y-m-d', $datetime_start);
$start = date('H:m:s', $datetime_start);
$end = date('H:m:s', $datetime_end);
$this->EZ_query->insert_activite($date, $start, $end);
}
If you think there is something I'm doing not correctly beside the time problem, I'm open to any pointers :), Thanks!

Your data formatting in php is not correct, minutes are denoted by i not m (which is used my month already). See here: http://php.net/manual/en/function.date.php
So change:
$start = date('H:i:s', $datetime_start);
$end = date('H:i:s', $datetime_end);

Display date from database using jquery fullcalendar

I'm using the jquery fullcalendar plugin. I can display dynamic dates on a button click. The issue I have now is when loading the dates from the db all the dates populate just one day.
Here is the code with the call to the web service:
$('#calendar').fullCalendar({
header: {
left: 'prev, next today',
center: 'title',
right: 'month, agendaWeek, agendaDay'
},
defaultView: 'month',
editable: true,
allDaySlot: false,
selectable: true,
slotMinutes: 15,
events: 'DAL/WebService1.asmx/GetEvents',
allDay:false
});
Here is the date from that web method

$('#calendar').fullcalendar('renderEvent',event_object,'stick')
This will attach your event to its date on the calendar. The event_object only needs a title and a start date to be valid, but I'd suggest adding an id to make editing/deleting easier.
Render event documentation

Figured out how to get the calendar to render dates separately with this code here. Hopefully helps somebody in the future
var events = [];
$('#calendar').fullCalendar({
events: function (start, end, timezone,callback) {
$.ajax({
url: 'DAL/WebService1.asmx/GetEvents',
dataType: 'json',
success: function (data) {
console.log(data);
var events = [];
$(data).each(function (index, d) {
events.push({
title: d.title,
start: d.startDate
});
});
callback(events);
}
});
}
});

How can i read events from my database table and show them in their respective dates in java script and jquery

i use Full calendar plugin to do this and i have done something but still did not get up to mark.
hear is my scripting code
$('#calendar').fullCalendar({
//theme: true,
header: {
left: 'prev,next today',
center: 'title',
right: 'month,agendaWeek,agendaDay'
},
buttonText: {//This is to add icons to the visible buttons
prev: "<span class='fa fa-caret-left'></span>",
next: "<span class='fa fa-caret-right'></span>",
today: 'today',
month: 'month',
week: 'week',
day: 'day'
},
editable: true,
droppable: true, // this allows things to be dropped onto the calendar
drop: function(date) { // this function is called when something is dropped
// retrieve the dropped element's stored Event Object
var originalEventObject = $(this).data('eventObject');
// we need to copy it, so that multiple events don't have a reference to the same object
var copiedEventObject = $.extend({}, originalEventObject);
// assign it the date that was reported
copiedEventObject.start = date;
copiedEventObject.backgroundColor = $(this).css("background-color");
copiedEventObject.borderColor = $(this).css("border-color");
console.log(copiedEventObject);
// render the event on the calendar
// the last `true` argument determines if the event "sticks" (http://arshaw.com/fullcalendar/docs/event_rendering/renderEvent/)
$('#calendar').fullCalendar('renderEvent', copiedEventObject, true);
// is the "remove after drop" checkbox checked?
/*alert(date + ' was moved ' + allDay + ' days\n' +
'(should probably update your database)');*/
},
//events:"web_master/mycal/ajax_fetch_calendar_data",
events: function(start, end, timezone, callback) {
$.ajax({
url: 'web_master/mycal/ajax_fetch_calendar_data',
dataType: 'json',
type: "POST",
success: function(doc) {
//console.log(doc);
var events = [];
$(doc).find('event').each(function(){
console.log(doc);
events.push({
title: $(this).attr('title'),
start: $(this).attr('start') // will be parsed
});
});
}
});
},
});
in this i successfully found my doc in events section.
here is the code to fetch events from DB
public function ajax_fetch_calendar_data()
{
try
{
$info = $this->mod_rect->fetch_calendar();
#pr($info);
for($i = 0 ; $i < count($info) ; $i++)
{
$rows[]= array("id"=>$info[$i]['i_id'],
"title"=> $info[$i]['s_title'],
"start"=> $info[$i]['dt_start_date'],
"end"=>$info[$i]['dt_end_date'],
"allDay"=> $info[$i]['s_allDay']);
}
if($rows)
{
echo json_encode($rows);
}
}
catch(Exception $err_obj)
{
show_error($err_obj->getMessage());
}
}
but there is an find(event) function which is didn't found.
Basically what i need to do that
i have some events, those are fetch from DB and i have to drag them on the specific date on the date that comes(upto this done), but i want to store that in Db and fetch them from DB.
I am new to java script and jquery and i didn't know about JSON also.
any help regarding this will helpfull to me.
Thanks.

Well
After few days I have done it myself.
And I think it would be help full to someone So i update my Question
In the Events Section of Fullcalendar for reading multiple events and showing them in your Fullcalendar
events: function(start, end, callback) {
$.ajax({
url: 'web_master/mycal/ajax_fetch_calendar_data',
dataType: 'json',
type: "POST",
success: function(doc) {
var eventObject = [];
for(i=0;i<doc.length;i++)
{
eventObject.push({
id : doc[i].id,
start : doc[i].start,
end : doc[i].end,
title : doc[i].title
//allDay : doc[i].allDay,
//backgroundColor : doc[i].backgroundColor,
//borderColor : doc[i].borderColor
});
}
callback(eventObject);
}
});
},
And i fetch it from my DB in this way
public function ajax_fetch_calendar_data()
{
try
{
$info = $this->mod_rect->fetch_calendar();
echo json_encode($info);
}
catch(Exception $err_obj)
{
show_error($err_obj->getMessage());
}
}

Full calendar filtering

My view code where full calendar is displayed is below:
<div class="content">
<div id='input'>
<?php echo form_dropdown("package_id", $packagelist, "",'id="packageid"'); ?>
</div>
<div id='calendar'></div>
</div>
<style>
#calendar {
max-width: 900px;
margin: 0 auto;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
$('#packageid').change(function() { //any select change on the dropdown with id country trigger this code
//$('#calendar').fullCalendar ('removeEvents');
var packageid = $('#packageid').val();
alert(packageid);
if(packageid !== null)
{ $('#calendar').fullCalendar({
//var $pid = packageid;
header: {
left: 'prev,next today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
displayEventEnd: {
month: true,
basicWeek: true,
"default": true
},
defaultDate: '2014-11-12',
//editable: true,
eventLimit: false, // allow "more" link when too many events
events:
"<?php echo base_url('admin/schedule/scheduledetails/hel/');?>"+"/"+packageid,
});
}
});
});
</script>
When i click the dropdown selection for the first time , then the filtered events is displayed on calendar. But when i click another item on the dropdown menu then no change occurs on the calendar. Now if i refresh the page and select another item from dropdown, then the calendar with filtered events is displayed. Now again if i try to change the dropdown selection, no change occurs on the calendar. What am i doing wrong. I have called the javascript to display the calendar after the onchange function.
EDIT 2: Now I have edited my code to something like this:
<script type="text/javascript">
$(document).ready(function(e) {
$('#calendar').fullCalendar('removeEvents');
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
displayEventEnd: {
month: true,
basicWeek: true,
"default": true
},
defaultDate: '2015-11-12',
//editable: true,
eventLimit: false, // allow "more" link when too many events
events: "<?php echo base_url('admin/schedule/scheduledetails/json/')?>",
cache : false,
});
});
</script>
this script is for displaying the calendar initially with the overall events.
Now the following script is done for filtering the events:
<script>
$(document).ready(function() {
$('#packageid').change(function() { //any select change on the dropdown with id country trigger this code
$('#calendar').fullCalendar ('removeEvents');
var packageid = $('#packageid').val();
// alert(packageid);
$('#calendar').fullCalendar('removeEvents');
$('#calendar').fullCalendar('addEventSource', '<?php echo base_url();?>admin/schedule/scheduledetails/hel/'+packageid);
//$('#calendar').fullCalendar('removeEvents');
});
});
</script>
The problem that is occuring is that . The calendar is initially loaded with the whole data. And when i click the dropdown button for filtering , the filtering ocurs. If i click the prev or next button on full calendar , then also it works without event being duplicated.
Now if i select the next event from the database, again the filtering occurs perfectly. But when i click the previous or next button , the events of previous dropdown selection plus the present dropdown selection is displayed on the fullcalendar view. Why is it happening? I have used removeEvents . Why isnot it working?

Your calling fullCalendar to create the calendar new each time, you need to destroy it, or just change the source and refresh:
what i do here is add a new source; if you want to change/remove the old source you can do that, just save the event source in a variable to be used in the 'removeEventSource' call before the 'addEventSource' call.
<script type="text/javascript">
$(document).ready(function() {
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
displayEventEnd: {
month: true,
basicWeek: true,
"default": true
},
defaultDate: '2014-11-12',
//editable: true,
eventLimit: false, // allow "more" link when too many events
events:
"<?php echo base_url('admin/schedule/scheduledetails/hel/');?>"+"/"+packageid,
});
$('#packageid').change(function() { //any select change on the dropdown with id country trigger this code
var packageid = $('#packageid').val();
alert(packageid);
if( packageid != null ) {
$('#calendar').fullCalendar('addEventSource', '/admin/schedule/scheduledetails/hel/'+packageid);
}
}
});
});
</script>

Here is what I did to implement filtering with FullCalendar. Event is triggered by use of a dropdown. Initial view shows all events. Using dropdown triggers the filters. Filters hold across month, week and day views.
$(document).ready(function() {
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
defaultDate: (new Date()).toISOString().substring(0, 10),
navLinks: true, // can click day/week names to navigate views
editable: true,
eventLimit: true, // allow "more" link when too many events
events: 'include/myfeed.php'
});
});
function filterByDealer(dealer){
$('#calendar').fullCalendar('removeEvents');
$('#calendar').fullCalendar('addEventSource','include/myfeed.php?d='+dealer);
}
