Populate the department select with the current value in the Edit Employee Form

I need to do the following to finish off my project and as im just learning but need bit of guidance to do the following:
it seems im not populating the department select with the current value in the 'edit employee form', ive been told if i use the getPersonnel.php file it returns the JSON to populate the department select, then all i need to do is set the value of the select to the departmentID value of the employee.
I also know and im going to change my php code to prepared statements to avoid sql injection.
this is my code below:
function updateEditEmployeeModal(employee) {
$.ajax({
url: './php/getPersonnel.php',
type: 'POST',
datatype: 'json',
data: {employeeId: employee.id},
success:function(result){
// console.log(result);
$('#editEmployeeId').html(result.data.personnel[0].id);
$('#editEmployeeFirstNameInput').val(`${result.data.personnel[0].firstName}`);
$('#editEmployeeLastNameInput').val(`${result.data.personnel[0].lastName}`);
$('#editEmployeePositionInput').val(result.data.personnel[0].jobTitle);
$('#editEmployeeEmailInput').val(result.data.personnel[0].email);
$("#editEmployeeDepartmentSelect").val(result.data.personnel[0].departmentId).change();
},
error: function(err){
console.log(err);
}
});
and getPersonnel.php file ::
<?php
// example use from browser
// http://localhost/companydirectory/libs/php/getPersonnel.php?id=1
// remove next two lines for production
ini_set('display_errors', 'On');
error_reporting(E_ALL);
$executionStartTime = microtime(true);
include("config.php");
header('Content-Type: application/json; charset=UTF-8');
$conn = new mysqli($cd_host, $cd_user, $cd_password, $cd_dbname, $cd_port, $cd_socket);
if (mysqli_connect_errno()) {
$output['status']['code'] = "300";
$output['status']['name'] = "failure";
$output['status']['description'] = "database unavailable";
$output['status']['returnedIn'] = (microtime(true) - $executionStartTime) / 1000 . " ms";
$output['data'] = [];
mysqli_close($conn);
echo json_encode($output);
exit;
}
// first query
$employeeId = $_REQUEST['employeeId'];
$query = $query = "SELECT p.id, p.lastName, p.firstName, p.jobTitle, p.email, p.departmentID as departmentId, d.name as department, l.name as location FROM personnel p LEFT JOIN department d ON (d.id = p.departmentID) LEFT JOIN location l ON (l.id = d.locationID) WHERE p.id = '$employeeId';";
$result = $conn->query($query);
if (!$result) {
$output['status']['code'] = "400";
$output['status']['name'] = "executed";
$output['status']['description'] = "query failed";
$output['data'] = [];
mysqli_close($conn);
echo json_encode($output);
exit;
}
$personnel = [];
while ($row = mysqli_fetch_assoc($result)) {
array_push($personnel, $row);
}
$output['status']['code'] = "200";
$output['status']['name'] = "ok";
$output['status']['description'] = "success";
$output['status']['returnedIn'] = (microtime(true) - $executionStartTime) / 1000 . " ms";
$output['data']['personnel'] = $personnel;

Print directly to printer without displaying dialog box with php or javascript

I have a system for a restaurant that is running on a web server and I need to print the order that is made, in a POS printer but I would like when the user clicks on "save order" button, automatically the ticket is printed with all details of the order, without showing any print dialog box (the dialog box is shown when I print with javascript and I don't want that).
I tried to do it with the php library "Mike42" and setting the shared printer but it does not print anything.
If I do it from my system in Local with XAMPP it is printed, but if I do it from the system that is hosted in my web hosting it does not print anything.
Here I show the code of the php files that does the job of sending to print:
windows-usb.php (this file is include in Mike42 library):
/* Change to the correct path if you copy this example! */
require __DIR__ . '/../../autoload.php';
use Mike42\Escpos\Printer;
use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;
/**
* Install the printer using USB printing support, and the "Generic / Text Only" driver,
* then share it (you can use a firewall so that it can only be seen locally).
*
* Use a WindowsPrintConnector with the share name to print.
*
* Troubleshooting: Fire up a command prompt, and ensure that (if your printer is shared as
* "Receipt Printer), the following commands work:
*
* echo "Hello World" > testfile
* copy testfile "\\%COMPUTERNAME%\Receipt Printer"
* del testfile
*/
try {
// Enter the share name for your USB printer here
//$connector = null;
$connector = new WindowsPrintConnector("THERMAL PRINTER");
/* Print a "Hello world" receipt" */
$printer = new Printer($connector);
$printer -> text("<table border='0' align='center' width='385px'><tr><td align='center'>.::<strong> ". $restaurent ." </strong>::.\n ". $celphone ." - ID: ". $IDRest ."</td></tr><tr><td align='center'>Date/Time:" . date('d-m-Y H:i:s') .

This prints very well if I do it in Local, using Xampp, but when I try to do it from the system that I have hosted in my web hosting it does not work, it does not send anything to print.
I also tried creating the ticket in a pdf file with the fpdf library and then calling the Autoprint () function but the disadvantage is that I must open the generated pdf file to the printing process starts, and that's not a good
idea.
¿is There some way to print directly to a printer with php or javascript (without displaying dialogue boxes.)?

Why does my ajax login script won't work?

I need an AJAX Login Script for my school project.
But it actually won't work because when I try to login, I get kicked to the startpage (login-form) without any message.
That's my backend-script (login2.php):
if(empty($_POST['loginEmail']) || empty($_POST['loginPassword'])) {
$error[] = "Bitte füllen Sie alle Felder aus!";
}
if (!empty($_POST['loginEmail']) && !filter_var($_POST['loginEmail'], FILTER_VALIDATE_EMAIL)) {
$error[] = "Bitte geben Sie eine gültige E-Mail-Adresse an!";
}
if(count($error)>0) {
$resp['msg'] = $error;
$resp['status'] = false;
echo json_encode($resp);
exit;
}
$sql = "SELECT * FROM `users` WHERE `uEmail` = :email AND `uPassword` = :password";
$stmt = $conn->prepare($sql);
$stmt->execute(array(':email' => $_POST['loginEmail']));
$row = $stmt->fetchAll(PDO::FETCH_ASSOC);
if(count($row)>0) {
if(!password_verify($_POST['loginPassword'],$row[0]['uPassword'])) {
$error[] = "Falsches Passwort!";
$resp['msg'] = $error;
$resp['status'] = false;
echo json_encode($resp);
exit;
}
session_start();
$_SESSION['Email'] = $row[0]['uEmail'];
$resp['redirect'] = "dashboard.php";
$resp['status'] = true;
echo json_encode($resp);
exit;
}
else {
$error[] = "Falsche E-Mail-Adresse!";
$resp['msg'] = $error;
$resp['status'] = false;
echo json_encode($resp);
exit;
}
And this is my JS part of the login form:
$(function() {
$('#login').click(function(e){
let self = $(this);
e.preventDefault();
self.prop('disabled',true);
var data = $('#login-form').serialize();
$.ajax({
url: '/login2.php',
type: "POST",
data: data,
}).done(function(res) {
res = JSON.parse(res);
if(res['status']) {
location.href = "dashboard.php";
} else {
var errorMessage = "";
console.log(res.msg);
$.each(res['msg'],function(index,message) {
errorMessage += '<p>' + message + '</p>';
});
$("#error-msg").html(errorMessage);
$("#error-msg").show();
self.prop('disabled',false);
}
}).fail(function() {
alert("error");
}).always(function(){
self.prop('disabled',false);
});
});
});
When I try to add action="/login2.php" in the form I get a HTTP 500 Error and the message, that it can not process this request at this time.

I'm not sure if this is your main problem, but it's a significant one. You're preparing two parameters:
$sql = "SELECT * FROM `users` WHERE `uEmail` = :email AND `uPassword` = :password";
But you're only binding one:
$stmt->execute(array(':email' => $_POST['loginEmail']));
You don't want to include the password in the select, since you're using password_verify() to validate it later. Change your SQL to this:
$sql = "SELECT * FROM `users` WHERE `uEmail` = :email";

Having json inside autocomplete

How come autocomplete doesnt work when I got json data that has items in it? I can se that it is becoming a list, but it is not filling with names.
Example of my json data: http://nettport.com/no/stram/search.php?term=e
<script>
$(function() {
$( "#inp_meal_a_0" ).autocomplete({
source: 'search.php'
});
$('#inp_meal_a_0').on('autocompleteselect', function (e, ui) {
var val = $('#inp_size_a_0').val();
var energy = ui.item.energy;
var proteins = ui.item.proteins;
var carbohydrates = ui.item.carbohydrates;
var fat = ui.item.fat;
$("#inp_energy_a_0").val((energy*val)/100);
$("#inp_proteins_a_0").val((proteins*val)/100);
$("#inp_carbs_a_0").val((carbohydrates*val)/100);
$("#inp_fat_a_0").val((fat*val)/100);
});
});
