Why won't my delete function respond to the button? - php

Question

I have a problem my delete function does not work he does not delete the organisation. When I press the button it show the text if I want to delete it I say yes but it only refreshes the site. I am not an advanced programmer and some of the code I did not write myself someone else worked on the project before me so idk why he some codes are written this way and he did not use any framework.
My code
<?php
if ($_SERVER['REQUEST_METHOD'] == "POST") {
if (isset($_FILES['croppedImage'])) logoChange();
// change organisation information is not made yet
if (isset($_POST['update'])) echo "This function is not made yet!";
if (isset($_POST['deleteOrganisation'])) DeleteOrganisations();
}
//this is the logoChange function
function logoChange() {
include '../../../include/db_conn.php';
//get organisation_id
$organisation_id = $_POST['organisation_id'];
//blob file info
$fileName = $_FILES['croppedImage']['name'];
$fileTmpName = $_FILES['croppedImage']['tmp_name'];
$fileSize = $_FILES['croppedImage']['size'];
$fileError = $_FILES['croppedImage']['error'];
//change blob to png
$fileType = 'png';
//check if image is able to upload
if ($fileError === 0) {
//check if file is not too big change number to needs!
if ($fileSize < 1000000) {
//make new random filename
$fileNameNew = uniqid('', true).".".$fileType;
$fileDesination = '../../../img/uploads/'.$fileNameNew;
move_uploaded_file($fileTmpName, $fileDesination);
//check if organisation already has a logo
$get_organisation_stmt = $conn->prepare('SELECT `organisation_logo` FROM `organisations` WHERE `organisation_id` = ?');
$get_organisation_stmt->bind_param('s', $organisation_id);
$get_organisation_stmt->execute();
$result_organisation = $get_organisation_stmt->get_result();
$row = mysqli_fetch_assoc($result_organisation);
if (is_null($row['organisation_logo'])) {
//if not inserted it
$sqlUpdateLogo = 'UPDATE `organisations` SET `organisation_logo`="'.$fileNameNew.'" WHERE `organisation_id` ="'.$organisation_id.'"';
mysqli_query($conn, $sqlUpdateLogo);
echo 'image inserted';
} else {
//else replace it
unlink('../../../img/uploads/'.$row['organisation_logo']);
$sqlUpdateLogo = 'UPDATE `organisations` SET `organisation_logo`="'.$fileNameNew.'" WHERE `organisation_id` ="'.$organisation_id.'"';
mysqli_query($conn, $sqlUpdateLogo);
echo 'image replaced';
}
}
else {
echo "File to big";
}
} else {
echo "Error in file";
}
}
// here i made the delete function
function DeleteOrganisations() {
include '../../../include/db_conn.php';
//delete the organisation
$getDeleteOrganisation = $_POST['deleteOrganisation'];
$delete_organisation_stmt = $conn->prepare('DELETE FROM `organisations` WHERE `organisation_id`= ?');
$delete_organisation_stmt->bind_param('i', $getDeleteOrganisation);
$delete_organisation_stmt->execute();
$delete_organisation_stmt->close();
}
here are the functions and here is JavaScript
//link for datatable functions
$(document).ready(function(){
$('#organisations').DataTable({
"columnDefs": [
{ "orderable": false, "targets": [0, 5] }
],
"order": [[ 1, "asc" ]]
});
});
//open edit modal for logo
$(document).on("click", ".btnopenEditLogo", function(e) {
event.preventDefault();
var organisationId = $(this).val();
var url = "functions/getOrganisationActions.php";
$.ajax({
type: 'POST',
url : url,
data: {'HiddenLogoid': organisationId},
success: function (data) {
$('#myLogoEditModal').modal('show');
$("#myLogoEditModal .modal-body").html(data);

$("#myOrganisationEditModal .modal-body").html(data);
}
});
});
//delete organisation
$(document).on("click", ".btnRemoveOrganisation", function(e) {
event.preventDefault();
var remove = $(this).val();
var url = "../cms/organisations/functions/postOrganisationActions.php";
Swal.fire({
title: 'Delete this test?',
text: "If you delete the test the questions and all statistics will be lost!",
type: 'warning',
showCancelButton: true,

}).then((result) => {
if (result.value) {
$.ajax({

url : url,
data: {'deleteOrganisation': remove},
success: function (data) {
Swal.fire({
title: 'Deleted!',
text: "You deleted the survey!",
type: 'success',
confirmButtonColor: '#3085d6',
confirmButtonText: 'OK'
}).then((result) => {
if (result.value) {
window.location.reload();
}
});
}
});
} else if (result.dismiss === Swal.DismissReason.cancel) {
Swal.fire (
'Cancelled',
'Your test is safe :)',
'error'
)
}
});
});
