I can't redirect user after login

I have login page which take username and password from user after user will be login. I am getting response for successfully login. but I can not redirect to index.php.
I am getting console message that User successfully login, But then page is not redirect on other page.
My JS file is like this.
$(document).ready(function() {
//alert('ss');
$("#login-form").submit(function(e){
e.preventDefault();
var username = $("#email").val();
var password = $("#password").val();
var isValid = true;
var re = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if(!re.test($("#email").val())){
isValid = false;
$("#message").html("Please enter valid email.");
}
if($('#remember').is(':checked')){
$.cookie('adminCookie', $("#loginUser").val(), { expires: 7 });
}
else{
if($.cookie('adminCookie') == null) {
$.removeCookie("adminCookie");
}
}
if(password == ""){
isValid = false;
$("#message").html("Please enter password.");
}
if(isValid){
$.ajax({
type : "POST",
url : "process/login.php?rand="+Math.random(),
data : {
username : $("#email").val(),
password : $("#password").val(),
}
}).
done(function(response){
//alert(response);
var JSONArray = $.parseJSON(rawJSON);
console.log(response);
if(jsonObj.success=="1"){
window.location("index.php");
}else{
$("#userDiv").addClass("form-group has-error");
$("#passDiv").addClass("form-group has-error");
$("#passWarning").css("display","");
$("#passWarning").html("Invalid User Name or Password");
$.when($('#passWarning').fadeOut(5000)).done(function() {
$("#userDiv").attr('class', 'form-group');
$("#passDiv").attr('class', 'form-group');
});
}
}).fail(function(){
}).always(function() {
});
}
});
});
my PHP file is looks like this.
<?php
include "../connection.php";
extract($_POST);
$data = array();
$resArr = array();
if (isset($_POST['username']) && isset($_POST['password'])) {
$check_user = mysqli_query($conn, "select * from cut_users where email like '$username' and password like '$password' and user_role like 'A'");
if ($check_user) {
if (mysqli_num_rows($check_user) > 0) {
$message = "Login successfully.";
$success = 1;
while ($row = mysqli_fetch_array($check_user)) {
if ($row['is_active'] == "0") {
$message = "Your account is blocked. Please contact admin.";
$success = 0;
}
$data["id"] = $row['cut_users_id'];
$data["name"] = $row['name'];
$data["emailID"] = $row['email'];
$data["device"] = $row['device_type'];
$data["is_reset"] = $row['is_reset'];
$_SESSION['userID'] = $row['cut_users_id'];
$_SESSION['name'] = $row['name'];
$_SESSION['emailID'] = $row['email'];
}
$resArr = array("success" => $success, "data" => $data, "message" => $message);
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Email or password invalid.");
}
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Something went wrong!!!" . mysqli_error($conn));
}
} else {
$resArr = array("success" => 0, "data" => array(), "message" => "Parameter Missing");
}
header('Content-Type: application/json');
echo str_replace("\/", "/", json_encode($resArr, JSON_UNESCAPED_UNICODE));
?>

1) Why you are using variable jsonObj instead of response ?
2) Modify your if statement like this
if(response.success==1){
window.location.href="index.php";
}

window.location is not a function it is an object. Please change href property in window.location object to redirect to new url.
window.location.href = "./index.php";

Simple redirect to specific file
if(jsonObj.success==1)
{
window.location.href = "http://www.example.com/index.php";
}

How to embed Javascript function in restful api in php?

I have the following code in one of api files(DispatchJob_Public) and i need ajax here to call the other file(selectDriverForJobResult) after 2 minutes. I can do that in php with sleep(), but that will keep the server busy. Ajax call is at the end of the php code. Can i embed js in api code? Or is there any alternate to do what i am trying to do.
Moreover i have got response from the first file(DispatchJob_Public), but no response from the second file(selectDriverForJobResult) when i called the endpoint in postman. Because the call wasn't made. If the second file was called, it should have return some response. The strange thing is that i get response from second file when i run it in browser. I think that is because the browser supports the javascript but the call made from android to the end point doesn't support that.
Please can i get any solution for this?

Empty POST on Angular/PHP

I'm new to Angular 4. I've added a simple HTTP POST login & connected it to another, simple, PHP receiver which then connects to the DB to check if the credentials are correct.
Bad Code:
login(username: string, password: string){
var headers = new Headers();
var creds ='http://localhost/crm/login/login.php';
headers.append('content-type', 'application/X-www-form=urlencoded');
return this._http.post(creds, {username: username, password: password}, {headers})
.map((response: Response) => {
let user = response.json();
if(user && user.accid){
this.isLoggedIn = true;
this.loginType = user.accid;
sessionStorage.setItem('accid', JSON.stringify(user.accid));
sessionStorage.setItem('status', JSON.stringify(user.status));
sessionStorage.setItem('username', JSON.stringify(user.user));
sessionStorage.setItem('uniqid', JSON.stringify(user.uniqid));
return user;
}else
return false;
});
}
The issue is, if I POST, the PHP server does not read any input at all, as if I POSTed nothing.
This is how I "fixed" it, but really this isn't a fix at all. This is basically using GET, except that I format the string itself. Obviously this is a horrible walkaround since now I have to accept GET requests on the PHP body, and the request itself is literally printed out in the browser's console on login.
login(username: string, password: string){
var headers = new Headers();
var creds ='http://localhost/crm/login/login.php?' + 'username=' + username + '&password=' + password;
headers.append('content-type', 'application/X-www-form=urlencoded');
return this._http.post(creds, '', {headers})
.map((response: Response) => {
let user = response.json();
if(user && user.accid){
this.isLoggedIn = true;
this.loginType = user.accid;
sessionStorage.setItem('accid', JSON.stringify(user.accid));
sessionStorage.setItem('status', JSON.stringify(user.status));
sessionStorage.setItem('username', JSON.stringify(user.user));
sessionStorage.setItem('uniqid', JSON.stringify(user.uniqid));
return user;
}else
return false;
});
}
PHP body
<?php
require_once '../config.php';
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
$parmSir = [];
if($_GET)
foreach($_GET as $gettie)
$parmSir[] = $gettie;
if($_POST)
foreach($_POST as $postie)
$parmSir[] = $postie;
$username = isset($parmSir[0]) ? $parmSir[0] : NULL;
$password = isset($parmSir[1]) ? $parmSir[1] : NULL;
$username = stripslashes($username);
$password = stripslashes($password);
$username = mysqli_real_escape_string($connection, $username);
$password = sha1($password, true);
$response = [];
$query = mysqli_query($connection, "SELECT * FROM user_accounts WHERE password='$password' AND username='$username'");
$rows = mysqli_num_rows($query);
if ($rows == 1){
$query = mysqli_query($connection, "SELECT account_type, employee_ID FROM user_accounts WHERE username ='$username'");
$row = $query->fetch_assoc();
$response['status'] = 'loggedin';
$response['accid'] = $row['account_type'];
$response['user'] = $username;
$response['uniqid'] = $row['employee_ID'];
}
else
$response['status'] = 'error';
echo json_encode($response);
?>
Not exactly sure why the PHP isn't recognizing POST/GET requests unless if I format the string in that specific manner. What am I doing wrong?

The solution is to ensure the header's 'content-type' is 'application/json'. Otherwise, _POST and _GET will not read the content as required (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Type).
Other posts have recommended to use $HTTP_RAW_POST_DATA (now deprecated, replaced with php://input which I now use).
Here is how it now looks like:
login(username: string, password: string){
var headers = new Headers();
var creds ='http://localhost/crm/login/login.php';
headers.append('content-type', 'application/json');
return this._http.post(creds, {username: username, password: password}, {headers})
.map((response: Response) => {
let user = response.json();
if(user && user.accid){
this.isLoggedIn = true;
this.loginType = user.accid;
sessionStorage.setItem('accid', JSON.stringify(user.accid));
sessionStorage.setItem('status', JSON.stringify(user.status));
sessionStorage.setItem('username', JSON.stringify(user.user));
sessionStorage.setItem('uniqid', JSON.stringify(user.uniqid));
return user;
}else if(user.status == "error"){
return false;
}else
return false;
});
}
And the .PHP:
<?php
require_once '../config.php';
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
if(strcasecmp($_SERVER['REQUEST_METHOD'], 'POST') != 0){
throw new Exception('Request method must be POST!');
}
$input = json_decode(trim(file_get_contents('php://input')),true);
$username = $input['username'];
$password = $input['password'];
$username = stripslashes($username);
$password = stripslashes($password);
$username = mysqli_real_escape_string($connection, $username);
$password = sha1($password, true);
$response = [];
$query = mysqli_query($connection, "SELECT * FROM user_accounts WHERE password='$password' AND username='$username'");
$rows = mysqli_num_rows($query);
if ($rows == 1){
$query = mysqli_query($connection, "SELECT account_type, employee_ID FROM user_accounts WHERE username ='$username'");
$row = $query->fetch_assoc();
$response['status'] = 'loggedin';
$response['accid'] = $row['account_type'];
$response['user'] = $username;
$response['uniqid'] = $row['employee_ID'];
}
else
$response['status'] = 'error';
echo json_encode($response);
?>

Alert message not working using php

I was trying to code where whenever I hit the submit button it will show an alert message when there's no data fetch. Can anyone help me?
if(isset($_POST['submitEstatus'])) {
if($_POST['empValue'] == $valEmp AND $_POST['ageValue'] == $valAge AND $_POST['genValue'] == $valGen){
$query = "SELECT * FROM users $valEmp $valAge $valGen";
$result = mysql_query($query);
if ($result = 0) {
$message = "No Data";
echo "<script type='text/javascript'>alert('$message');</script>";
} else {
while($row = mysql_fetch_array($result)){
$lat = $row['lat'];
$lon = $row['lon'];
$fname = $row['fname'];
$address = $row['address'];
echo("addMarker($lat, $lon, '<b>$fname</b><br />$address');\n");
$ageSelected = $valAge;
$empSelected = $valEmp;
$genSelected = $valGen;
}
}
}
I have this error:
mysql_fetch_array() expects parameter 1 to be resource, integer given
in C:\xampp\htdocs\admin\mapcon.php on line 20

On your if statement you are not comparing the value:
if ($result = 0) { ....
You are setting 0 to $result.
You should use

Variable getting via Ajax is empty ( Phonegap-Ajax-Json-PHP-MySQL )

I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_POST);) right after i am getting the $usernamefrom ajax in the PHP and run my app, I saw this alert: array(1){ [\"username\"]=> string(2) \"hi"\" }
When I added these lines: if (empty($username)) { echo '...' } , after I run my app, I saw that in the alert inside the error: ... part of the ajax, it is printed the echo that is inside this if. So, the $username is empty for sure.
This is my JavaScript file: (I get correctly for sure all the values from html so Focus on the two Ajax parts of code)

This is my PHP file in which I check if the username already exists (Username = Primary Key):

//var_dump($_POST);
//if (empty($username)) {

$sql = "SELECT COUNT(*) as Count FROM `user` WHERE `username`='$username'";
$result= mysql_query($sql, $con);

if (!$result) {

//$response_array['status'] = 'error';
//echo json_encode($response_array);
