getting unexpected output from ajax

I am creating wishlist where I am sending data via ajax but it's not returning data as I implemented in the code I fail to figure out what is the main reason behind this. Here is the code
<li><span><i style="color:red;" class="<?php
if(isset($_SESSION['email'])){
$selwishlist = $con->prepare("SELECT * FROM wishlist WHERE user_id =:userid and product_id =:productid ");
$selwishlist->bindParam(":userid",$userid);
$selwishlist->bindParam(":productid",$id);
$selwishlist->execute();
$selresultwishlis = $selwishlist->rowCount();
if($selresultwishlis > 0){
echo "fa fa-heart";}else{
echo "ion-android-favorite-outline";
}}else{
echo "ion-android-favorite-outline";
}
?> wishlist-click" id="wishlist-product-id-<?php echo $id; ?>"></i></span>
</li>
if(isset($_SESSION['email'])){
$email = $_SESSION['email'];
$userdetail = $con->prepare("SELECT * FROM user WHERE email = :email");
$userdetail->bindParam(":email",$email);
$userdetail->execute();
$userres = $userdetail->fetch();
$userid = $userres['id'];
}
else{
$email = '';
$userid = '';
}
This is my input button Where first I check if the session is running or not an then check if the item is in the user wishlist or not and according to that I change the class of wishlist icon
$(".wishlist-click").click(function(e){
e.preventDefault();
var el = $(this);
alert('I am clicked')
var ids = this.id;
var splitids = ids.split('-');
var wishlistid = splitids[3];
$.ajax({
url:'wishlistajax.php',
type:'POST',
data:{ids:wishlistid},
success:function(response){
if(response == 1){
alert('1');
}else if(response == '0'){
alert('0');
}else if(response == '3'){
alert('its 3');
}
else{
alert('Not in All');
}
}
});
});
This is my jquery code and I am getting Not in both in response AND HERE IS MY AJAX CODE
<?php
session_start();
if(isset($_SESSION['email'])){
echo "1";
exit();
if(isset($_POST['ids'])){
$email = $_SESSION['email'];
$productid = htmlspecialchars($_POST['ids']);
include "conn.php";
$userdetail = $con->prepare("SELECT * FROM user WHERE email = :email");
$userdetail->bindParam(":email",$email);
$userdetail->execute();
$userres = $userdetail->fetch();
$userid = $userres['id'];
$ip = $_SERVER['REMOTE_ADDR'];
$insertquery = $con->prepare("INSERT INTO wishlist (product_id, user_id) VALUES (:productid, :userid)");
$insertquery->bindParam(":productid",$productid);
$insertquery->bindParam(":userid",$userid);
$insertquery->execute();
echo 'Item added';
exit();
}}
else{
echo '2';
header("location:loginregister.php");
exit();
}
echo '3';
exit();
?>

Why is this AJAX call not working in IE 11?

I have a notifications system on my site, that utilizes AJAX to update in real-time. The problem is that it works on every browser except IE 11. After looking around I noticed some people advising to use cache:false in the call. However, this makes the code non-functional across all browsers. Anyone know what the solution is?
JAVASCRIPT:
<script>
$(document).ready(function(){
$('.notif_count').html('0');
function load_unseen_notification(view = '')
{
$.ajax({
url:"notif_follow.php",
method:"POST",
data:{view:view},
dataType:"json",
success:function(data)
{
$('.notif_follow').html(data.notification);
if(data.notif_count > 0)
{
$('.notif_count').html(data.notif_count);
}
}
});
}
load_unseen_notification();
$(document).on('click', '.notif', function(){
$('.notif_count').html('0');
load_unseen_notification('yes');
});
setInterval(function(){
load_unseen_notification();;
}, 5000);
});
</script>
PHP:
<?php
session_start();
require_once 'class.channel.php';
$user_notif = new USER();
$user_id = $_SESSION['userID'];
if(isset($_POST["view"]))
{
if($_POST["view"] != '')
{
$stmt = $user_notif->runQuery("UPDATE notif_follow SET status = 1 WHERE receive_id = ?");
$stmt->bindValue(1,$user_id);
$stmt->execute();
}
$stmt = $user_notif->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid"=>$user_id));
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$stmt = $user_notif->runQuery("SELECT * FROM notif_follow WHERE receive_id= ? ORDER BY id DESC LIMIT 5");
$stmt->bindValue(1,$user_id);
$stmt->execute();
$notifs = $stmt->fetchAll(PDO::FETCH_ASSOC);
$notification = '';
if(count($notifs) > 0)
{
foreach($notifs as $notif)
{
$send_id = $notif['send_id'];
$query2 = $user_notif->runQuery("SELECT * FROM following WHERE user1_id=:uid1 AND user2_id=:uid2");
$query2->execute(array(":uid1"=>$user_id,":uid2"=>$send_id));
$query2result = $query2->fetchAll(PDO::FETCH_ASSOC);
if(count($query2result) > 0){
$follow = '<button class="button" style="margin:2px;">Remove Channel</button>';
}
else{

';
}
}
else

}
$count = $user_notif->runQuery("SELECT * FROM notif_follow WHERE receive_id= ? AND status= 0");
$count->bindValue(1,$user_id);
$count->execute();
$countresult = $count->fetchAll(PDO::FETCH_NUM);
if(count($countresult) > 0){
$notif_count = count($countresult);
}
else{
$notif_count = 0;
}

echo json_encode($notif_array);

php and ajax JavaScript pagination comment system

Trying to build a commenting system. Were comments are posted with AJAX. With comment count with Pagination. I have success achieving both, but putting them together is another story. I have tried doing 2 ajax calls. One for getting records from the database and showing pagination. The other call for recording records to the database.
// this is the first ajax call to to get the results and show pagination buttons

How to push data from database and see vote count after each data?

What I'm trying to do is to allow students answer questions and see each vote after each question and then the teacher can push the next question. The votes will then be entered into the database which I can use to produce a chart. I currently have the student answering questions but I'm having problem on stopping the next question from coming so the poll vote can show and how to show the vote before the next question comes.
This gets the questions from the database:
function getQuestion(){
var hr = new XMLHttpRequest();
hr.onreadystatechange = function(){
if (hr.readyState==4 && hr.status==200){
var response = hr.responseText.split("|");
if(response[0] == "finished"){
document.getElementById('status').innerHTML = response[1];
}
var nums = hr.responseText.split(",");
document.getElementById('question').innerHTML = nums[0];
document.getElementById('answers').innerHTML = nums[1];
document.getElementById('answers').innerHTML += nums[2];
}
}
hr.open("GET", "questions.php?question=" + <?php echo $question; ?>, true);
hr.send();
function post_answer(){
var p = new XMLHttpRequest();
var id = document.getElementById('qid').value;
var url = "userAnswers.php";
var vars = "qid="+id+"&radio="+x();
p.open("POST", url, true);
p.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
p.onreadystatechange = function() {
if(p.readyState == 4 && p.status == 200) {
document.getElementById("status").innerHTML = '';
alert("Your answer was submitted"+ p.responseText);
var url = 'quiz.php?question=<?php echo $next; ?>';
window.location = url;
}
}
p.send(vars);
document.getElementById("status").innerHTML = "processing...";
}
On a different php file:
require_once 'core/init.php';
$arrCount = "";
if(isset($_GET['question'])){
$question = preg_replace('/[^0-9]/', "", $_GET['question']);
$output = "";
$answers = "";
$q = "";
$connection = mysqli_connect('localhost', 'root', '', 'alsp');
$sql = mysqli_query($connection,"SELECT id FROM questions");
$numQuestions = mysqli_num_rows($sql);
if(!isset($_SESSION['answer_array']) || $_SESSION['answer_array'] < 1){
$currQuestion = "1";
}else{
$arrCount = count($_SESSION['answer_array']);
}
if($arrCount > $numQuestions){
unset($_SESSION['answer_array']);
header("location: start-quiz.php");
exit();
}
if($arrCount >= $numQuestions){
echo 'finished|<p>There are no more questions. Please enter your username and submit</p>
<form action="userAnswers.php" method="post">
<input type="hidden" name="complete" value="true">
<input type="text" name="username">
<button class="btn btn-action" type="submit" value="finish">Submit</button>
</form>';
exit();
}
$singleSQL = mysqli_query($connection,"SELECT * FROM questions WHERE id='$question' LIMIT 1");
while($row = mysqli_fetch_array($singleSQL)){
$id = $row['id'];
$thisQuestion = $row['question'];
$type = $row['type'];
$question_id = $row['question_id'];
$q = '<h2>'.$thisQuestion.'</h2>';
$sql2 = mysqli_query($connection,"SELECT * FROM answers WHERE question_id='$question' ORDER BY rand()");
while($row2 = mysqli_fetch_array($sql2)){
$answer = $row2['answer'];
$correct = $row2['correct'];
$answers .= '<label style="cursor:pointer;"><input type="radio" name="rads" value="'.$correct.'">'.$answer.'</label>
<input type="hidden" id="qid" value="'.$id.'" name="qid"><br /><br />
';
}
$output = ''.$q.','.$answers.',<span id="btnSpan"><button onclick="post_answer()"class="btn btn-action">Submit</button></span>';
echo $output;
}
}
I'm guessing rather than have a submit button that takes you to the next page, after clicking on a radio button, the vote should show and then the teacher can push the next question. That's were the main issue is.
