What should I put in my updating.php when I need to update users status if online or offline every 5 seconds?

Hi I've made a messaging feature,it displays the receivers of the message in an account, beside the receiver's name is a green or red dot, for online or offline, it is successful when I log in 2 accounts and messaged each other, when I open the first account, the other account is offline, when I open the second account, the other is online, what my problem is I want to update their status in every five seconds so that their dot will be accurate whenever they log out or log in. I have made a javascript and ajax below this page left-col.php and I've tried copying the whole code, putting it to updating.php but it did not work, what should be the appropriate data inorder to update user receiver status in every 5 seconds inside the updating.php? and also, does my the javascript and ajax needs a library to be included that's why it didn't work? Please help.

innerHtml on responding ajax method

I am using ajax for sending data to PHP script and set a query in my database. my codes :
HTML script :
<span id="btn_span_<?php echo $user_id ?>">
<?php if ($online == 1) { ?>
<button onclick="update_online(1,<?php echo $user_id; ?>,'btn_span_<?php echo $user_id ?>')" class="btn-custom-delete btn btn-status">is active</button>
<?php } elseif ($online == 0) { ?>
<button onclick="update_online(0,<?php echo $user_id; ?>,'btn_span_<?php echo $user_id ?>')" class="btn-custom-services btn btn-status">active
</button>
<?php } ?>
</span>
JAVASCRIPT script :
function update_online(status, id, span_id) {
var settings = {
"async": true,
"crossDomain": true,
"url": "script_edit_status.php?status=" + status + '&id=' + id + '&span_id=' + span_id,
"method": "GET"
};
$.ajax(settings).done(function (response) {
var obj = JSON.parse(response);
var btn = document.getElementById(span_id);
if (obj.status == "1") {
btn.innerHTML = "<button onclick='update_online(1,obj.id,obj.span_id)' class='btn-custom-services btn btn-status'>active</button>";
} else if (obj.status == "0") {
btn.innerHTML = "<button onclick='update_online(0,obj.id,obj.span_id)' class='btn-custom-delete btn btn-status'>is active</button>";
}
});
}
PHP script :
<?php
include_once "../db/connection.php";
$id = $_GET['id'];
$status = $_GET['status'];
$span_id = $_GET['span_id'];
try {
if ($status == 1) {
$sql_edit_status = "update api_user set online=0 where id='$id';";
} elseif ($status == 0) {
$sql_edit_status = "update api_user set online=1 where id='$id';";
}
$conn->query($sql_edit_status);
$status_arr = array(
"id" => $id,
"status" => $status,
"span_id" => $span_id
);
echo json_encode($status_arr);
} catch (PDOException $e) {
echo "Error: " . $e->getMessage();
}
$conn = null;
it is ok for the first action but when I want to click to button for second time consol shows following error :
Uncaught ReferenceError: obj is not defined
The error is for innerHTML that don't send correctly methods...
Can you help me?

btn.innerHTML = "<button onclick='update_online(0," + obj.id + "," + obj.span_id + ")' class='btn-custom-delete btn btn-status'>is active</button>";

More than one timer on a page at a time

Okay I am wondering how I get two countdown timers on the one page?
<script type = 'text/javascript'>
window.onload=function() {
setInterval("<?php
$array = count($settime);
for ($i = 0; $i < $array; $i++) {
$thitime = explode(":", $settime[$i]);
echo "timeleft(" . $thitime[1] . ", " . $thitime[0] . "); ";
}
?>", 1000);
}
function timeleft(string, id)
{
var xmlhttp=GetXmlHttpObject();
if(xmlhttp==null) { alert("Sorry, Your browser doesnt support HTTP Requests");
return;
}
var elem = "time" + id;
var load = "time_left.php?string=" + string;
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState==4) {
document.getElementById(elem).innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", load, true);
xmlhttp.send(null);

The page I am trying to run the two timers off is only loading one of the timers, I have tried multiple things to try and fix the issue, and can't seem to figure out what it is that is wrong with it..
I even tried making two different timer scripts and that didn't work..
Here is the complete code of the page I want to run the two timers on..

Display a php cookie in html

I have set a cookie using php.
Here's my code:
<?php
include_once 'php/config.php';
session_start(); //starting the session for user profile page
if(!empty($_POST['username'])) //checking the 'user' name which is from Sign-In.html, is it empty or have some text
{
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
$query = mysql_query("SELECT * FROM users where username = '$username' AND password = '$password'") or die(mysql_error());
$row = mysql_num_rows($query) or die(mysql_error());
if($row==1)
{
$_SESSION['username'] = $username;
setcookie('username', $username, time() + (86400 * 30), "/"); // 86400 = 1 day
echo $_SESSION['username'];
echo "SUCCESSFULLY LOGGEDIN...";
echo "<script>setTimeout(function(){window.location.href='index.html'},2000);</script>";
}
else
{
echo "SORRY... YOU ENTERD WRONG ID AND PASSWORD... PLEASE RETRY...";
echo "<script>setTimeout(function(){window.location.href='index.html'},2000);</script>";
}
}
?>
I want display the 'username' cookie in html like Hi ""
.
Please Help.
Tried this javascript:
<script type="text/javascript">
function getCookie(name)
{
var re = new RegExp(name + "=([^;]+)");
var value = re.exec(document.cookie);
return (value != null) ? unescape(value[1]) : null;
}
</script>

Use echo $_COOKIE['username']; instead of echo $_SESSION['username'];. It will echo out of the second reload of the page. (Why?)

<span id="myId"><span>
<script>
document.getElementById('myId').innerHTML=listCookies()
function listCookies() {
var theCookies = document.cookie.split(';');
var aString = '';
for (var i = 1 ; i <= theCookies.length; i++) {
aString += i + ' ' + theCookies[i-1] + "\n";
}
return aString;
}
</script>

php | Defend move_upload_file or delete files from input[type="file"] using jQuery

I have an input[type="file"] had multiple option. I made it preview function so that user can delete the image by clicking the button before submit. The images are deleted well on browser by remove() function however the problem is the values of input including the deleted images are posted when i submit. I don't know how to delete real value of input.
I've tried to figure it out to delete in the server side.
This is the part of html code.
<div class="col-xs-4 vcenter from-group">
<span class="glyphicon glyphicon-asterisk" style="color:red;"></span><label for="inputScreenshots">스크린샷</label>
<p style="display:inline; padding-left:270px; color:red; font-size: 12px">* 이미지 사이즈 : 800 X 450</p>
<input type="file" id="inputScreenshots" name="inputScreenshots[]" class="form-control" accept="image/*" multiple>
<div id="filenameList" style="width : 400px">
<div id="insertScreenshots" style="margin : 30px; position :relative;">
<input type="hidden" name="screenshots_filename[]" value="<?=$screenshot_urls?>">
</div>
</div>
This is the php code where im trying to defend uploading images.
$ss_upload="false";
if (isset($_POST["del_screenshots"])){
// del_screenshots are images that deleted from client.
$ds_count = $_POST["del_screenshots"];
foreach($ds_count as $del) {
echo "<br/> del_screenshots : ".$del;
}
}
$ss_count = sizeof($_FILES['inputScreenshots']['tmp_name']);
// ss_count is the size of all images including deleted images from input field.
echo "<br/>ss_cout : ". $ss_count;
for ($i = 0; $i < $ss_count; $i++) {
$tmpFilePath = $_FILES['inputScreenshots']['tmp_name'][$i];
$tmp_filename = $_FILES['inputScreenshots']['name'][$i];
// tmp_filename is the posted real file name.
echo "<br/> tmp_filename".$i. " : " .$tmp_filename;
//=========================================================================
for ($j = 0; $j < sizeof($ds_count); $j++) {
// Compare all images name and deleted images name
if (strcmp($ds_count[$j] , $tmp_filename) == 0) {
echo "<br/>".$ds_count[$j] . " == " . $tmp_filename . "==> " ."true";
// The $tmp_filename has to be deleted. not to be uploaded to server.
// $tmp_filename = null;
}else {
echo "<br/>".$ds_count[$j] . " == " . $tmp_filename . "==> " ."false";
// This files are okay to be uploaded to server.
}
}
//=========================================================================
$ext = pathinfo($tmp_filename, PATHINFO_EXTENSION);
// $ext = pathinfo($_FILES['inputScreenshots']['name'][$i], PATHINFO_EXTENSION);
echo "<br/>". $i . " ext (pathinfo) : ". $ext;
if ($ext == "") {
continue;
$ss_upload="false";
}
$newFilePath = uniqid().".".$ext;
if ($screenshots != "") {
$screenshots .= "+";
}
$screenshots .= $newFilePath;
// $screenshots has be uploaded to DB except the deleted images. (ex : uniqFileName.png + uniqFileName.png + .. )
echo "<br/> 1) screenshots : ". $screenshots;
move_uploaded_file($tmpFilePath, $SS_PATH."/".$newFilePath);
$ss_upload="true";
}
I want to defend uploading the deleted images but it is no matter to use unlink() in somewhere. The point is how cant i make the string except the deleted images.
=========================================================================
I suppose there is another way to do in jQuery but i have no idea.
I'll put the code below.
$("#inputScreenshots").change(function(){
$("#filenameList div.notyet").remove();
for(var i = 0, len = this.files.length; i < len; i++){
var file = this.files[i];
var fr = new FileReader();
fr.onload = screenshots_processFile(file);
fr.readAsDataURL(file);
}
});
var screenshots_processFile = function screenshots_processFile(file) {
return (function(file) {
return function(e) {
var div = document.createElement("div");
$(div).addClass("notyet").css({
margin: "30px",
position: "relative"
});
var html = [,'<img src="" width="100%" id="tmp_screenshots">'
,'<button type="button" class="close img-close" aria-label="Close"><span aria-hidden="true">×</span></button>'
].join("");
$(div).append(html);
$(div).find("button").click(function() {
alert("remove");
//=========================================================== * TODO : remove the files in server!
var targetDom = document.getElementById( "filenameList" );
var targetInput = document.createElement("input");
targetInput.setAttribute("name", "del_screenshots[]" );
targetInput.setAttribute("type","hidden");
targetDom.appendChild(targetInput);
alert(file.name);
targetInput.setAttribute("value", file.name);
//===========================================================
$(this).parent().remove();
});
$(div).find("img").attr("src", e.target.result);
$("#filenameList").append(div);
}
})(file)
};
How can i do this? Does anyone have an idea?
-----------------------------------------------------------------------------------------------------------
I solved it like this. I know my code is so dirty :-/
$ss_upload="false";
