Ajax reload even without changes

To edit an event on Fullcalendar I click on an event, a modal apparead and is connected to a PHP file and has an AJAX call in JS.
The problem is: when I open the modal and close it, even if I have made no changes it reload the page. Can someone please explain what's the problems in these code, I cant seems to find a solution and it's pretty annoying that reload without making changes.
JS call:
$('#editNewEvent').modal('show').one('hidden.bs.modal', function (e) {
if(event.nomeUtente == $("#nomeUtente").data('value')){
event.title = $('#editEname').val();
event.start = $('#editStarts').val();
event.end = $('#editEnds').val();
$.ajax({
url: 'eventi/updateEvent.php',
type: 'POST',
data: {start: event.start, _id: event.idAssenza, end: event.end, title: event.title},
success: function(data) {
window.location.reload(true);
}
});
$('#calendar').fullCalendar('updateEvent', event._id);
}
});
PHP editEvents:
require_once "../config.php";
session_start();
$id = $_POST['_id'];
$ename = $_POST['title'];
$starts = $_POST['start'];
$ends = $_POST['end'];
$nomeUtente = $_SESSION['nomeUtente'];
// update the records
$sql = "UPDATE assenze SET ename = '$ename', starts = '$starts', ends = '$ends' WHERE idAssenza = $id AND nomeUtente = '$nomeUtente'"; //
if (mysqli_query($conn, $sql)) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . mysqli_error($conn);
}
mysqli_close($conn);

Because you trigger event it (hidden.bs.modal), event this will be call when you close modal -> call to -> eventi/updateEvent.php.
I suggest you should be call event update when only you click to button Salva modifiche

How do I redirect to same page on submitting a form in a bootstrap modal?

I have a bootstrap modal with form which is getting called from a link in my parent home page :
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Contact</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form method="post" action="student.php" target="_parent">
<div class="form-group row">
<div class="col">
<input type="text" class="form-control" placeholder="Name" name = "name">
</div>
<div class="col">
<label class="mr-sm-2 sr-only" for="inlineFormCustomSelect">Profession</label>
<select class="custom-select mr-sm-2" id="inlineFormCustomSelect" name="profession">
<option selected>Choose...</option>
<option value="1">Student</option>
<option value="2">Parent</option>
<option value="3">Other</option>
</select>
</div>
</div>
<div class="form-group">
<input type="text" class="form-control" placeholder="e-mail" name = "email">
</div>
<div class="form-group">
<label class="mr-sm-2 sr-only" for="inlineFormCustomSelect">Type</label>
<select class="custom-select mr-sm-2" id="inlineFormCustomSelect" name="type">
<option selected value="1">Feedback</option>
<option value="2">Grievance</option>
<option value="3">Admission</option>
<option value="4">Other</option>
</select>
</div>
<div class="form-group">
<label for="exampleFormControlTextarea1">Write..</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="3" name="message"></textarea>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-primary">Send Message</button>
</div>
</div>
</div>
</div>
PHP code in my parent page to handle data of my modal form.
<?php
if(isset($_POST["submit"]))
{
$email = $_POST["email"];
$name = $_POST['name'];
$message = $_POST["message"];
$type = $_POST["type"];
$profession = $_POST["profession"];
$message = wordwrap($message,70);
$headers = "From:".$email;
$subject = "Message by".$name." ".$profession."of type".$type;
mail("yashboura303#gmail.com", $subject, $message, $headers);
echo "Your mail has been sent successfuly ! Thank you for your feedback";
}
?>
Now I want to go back to home.php after submitting my modal form so that I can used mail() function to send mail. How can I achieve this?
I obviously used "action=home.php" in form which is not working and tired "data-dismiss='modal' " in submit button tag but it's not actually submitting the form it's just closing the modal.

keeping bootstrap modal active

hi how to keep bootstrap modal active after clicking submit button. In my case after clicking submit button it refresh the page so it close the modal. In my modal form i have a textboxes that when you click submit it will save the data in database. Now i have a php code that check the textboxes if their empty it will show/say the error and if not empty it will says success.
Thanks in advance who will help.
This is my code
<div class="modal fade" id="addtopic" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4>Add Topic</h4>
</div>
<form method="POST" action="index.php" role="form" id="saveform">
<div class="modal-body">
<div class="form-group">
<label for="cCategory">Category</label>
<input type="text" class="form-control" id="cCategory" name="category" value="<?php if (!empty($categ)) { echo $categ; } ?>">
</div>
<div class="form-group">
<label for="cTitle">Title</label>
<input type="text" class="form-control" id="cTitle" name="topicTitle" value="<?php if (!empty($topicTitle)) { echo $topicTitle; } ?>">
</div>
<div class="form-group">
<label for="cDesc">Description</label>
<textarea class="form-control custom-control" rows="3" style="resize:none" name="desc" value="<?php if (!empty($desc)) { echo $desc; } ?>"> </textarea>
</div>
<div class="form-group">
<label for="cDesc">Created By</label>
<input type="text" class="form-control" id="cDesc" name="createdby" value="<?php if (!empty($created)) { echo $created; } ?>">
</div>
</div>
<div class="modal-footer">
if($insert = $db->query("
INSERT INTO pncontent (category, title, description, createdby, dateadded)
VALUES ('$categ', '$topicTitle', '$desc', '$created', NOW() )
")) {
echo "<p class='pull-left'> Topic Save! </p>";
}else {
echo "<p class='pull-left'>Failed to Save</p>";
die($db->error);
}
}else {
echo "<p class='pull-left'>All Fields are required</p>";
$desc = $_POST['desc'];
$categ = $_POST['category'];
$topicTitle = $_POST['topicTitle'];
$created = $_POST['createdby'];
}
}
?>
<button type="submit" name="Sbt" class="btn btn-primary" >Save changes</button>
<button data-dismiss="modal" class="btn btn-danger">Close</button>
</div>
</form>
</div>
</div>
</div>

Where you return
echo "<p class='pull-left'>All Fields are required</p>";
Add this bit of code to open the modal on page load.
<script type="text/javascript">
$(window).load(function(){
$('#addtopic').modal('show');
});
</script>

Can't access DOM from SCM Music Player

I am building a website using SCM Music Player (an open source web player), and I would like to use the "finish" callback to modify my DOM when the music stops. I can access this callback and execute a "console.log()", but I can't access DOM... I've noticed that this script uses Knockout library, but I don't know how it works and if it is necessary... Here is my code from scm.js:
finish = function(){
//repeat one start again, otherwise next song
if(repeatMode()==2) start();
else {
console.log('Next son de scm.js :');
var div = ko.observable($('#ajouterSon').attr('role'));
console.log('Div: ' + div);
next();
}
};
And the kind of changes I do when I play a song :
$('.musiqueLink').on('click', function(event) {
console.log('clic musique - last id = ' + lastidmusique);
event.preventDefault();
if(lastidmusique != null)
document.getElementById('row'+lastidmusique).setAttribute("class", "row");
document.getElementById('row'+$(this).attr('data-idmusique')).setAttribute("class", "row highlighted");
SCM.play({title:$(this).attr('data-titre'),url:$(this).attr('data-lien')});
lastidmusique = $(this).attr('data-idmusique');
});
The dom which contains 'ajouterSon' :
<body style=" background-image: url('imgs/backgrnd.jpg'); background-size: 100% 100%; background-repeat:no-repeat; background-attachment:fixed;">
<div id="ajouterSon" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true">

passing result from php if statement, to javascript/html

I have a html file including this form with two hidden dialogues above it:
<div class="alert alert-success alert-dismissable" style="display:none;" id="success">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Success!</strong> Your asset has been added! </div>
<div class="alert alert-warning alert-dismissable" style="display:none;" id="fail">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Oops!</strong> Something went wrong! </div>
<form class="form-horizontal" action="http://localhost/php/insert.php" method="post">
<fieldset>
<!-- Form Name -->
<legend>Add An Asset</legend>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="name">Name</label>
<div class="col-md-5">
<input id="name" name="name" type="text" placeholder="" class="form-control input-md">
</div>
</div>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="serial">Serial Number</label>
<div class="col-md-5">
<input id="serial" name="serial" type="text" placeholder="" class="form-control input-md">
</div>
</div>
<!-- Select Basic -->
<div class="form-group">
<label class="col-md-4 control-label" for="location">Location</label>
<div class="col-md-5">
<select id="location" name="location" class="form-control">
<option value="1">Option one</option>
<option value="2">Option two</option>
</select>
</div>
</div>
<!-- Button -->
<div class="form-group">
<label class="col-md-4 control-label" for="singlebutton"></label>
<div class="col-md-4">
<button id="singlebutton" name="singlebutton" class="btn btn-primary" type="submit">Submit</button>
</div>
</div>
</fieldset>
</form>
and the php for the form is here, which is stored on a separate server and referenced:
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dissertation", $con);
$sql="INSERT INTO asset (name, serial)
VALUES
('$_POST[name]','$_POST[serial]')";
if (!mysql_query($sql,$con)) {
$errcode = "error_code=003";
}
$referer = $_SERVER['HTTP_REFERER'];
if ($errcode) {
if (strpos($referer, '?') === false) {
$referer .= "?";
}
header("Location: $referer&$errcode");
} else {
header("Location: $referer");
}
exit;
mysql_close($con)
?>
I need to some how change the if statement in the php to make the warning dialogue shown if there is an error code, and the success dialogue if not. I realise I'll need to use javascript .show() and .hide() but I don't know how to send the php response to the javascript/html file. I can't put the php in the html/javascript file, they need to stay separate.

)in your html file, do something like:
<div class="alert alert-success alert-dismissable" style="<?php echo (!isset($_GET['error_code'])||empty($_GET['error_code']))?"display:none;":"";?>" id="success">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Success!</strong> Your asset has been added! </div>
<div class="alert alert-warning alert-dismissable" style="<?php echo (isset($_GET['error_code'])&&!empty($_GET['error_code']))?"display:none;":"";?>" id="fail">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Oops!</strong> Something went wrong! </div>
...
...
:-)

Echo inline JavaScript:
<?php
if (error) {
echo "<script>$('selector').show()</script>";
} else {
echo "<script>$('selector').hide()</script>";
}
