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>";

JavaScript/AJAX prints weirdly

My JavaScript/AJAX prints comments. It's all good, until I want to insert/get more than one comment. It duplicates itself. This feels like a nesting/missed parenthesis problem in my code, but I can't be able to find it...
My JS code:
$(document).ready(function(){
var url = 'comment-get.inc.php';
$.getJSON(url, function(data) {
$.each(data, function(index, item) {
var t = '';
t += '<div class="comment_holder" id="_'+item.id+'">';
t += '<div class="user"> <img src="src/img/page3_img7.jpg" alt="" class="img_inner fleft">';
t += '<div class="extra_wrapper">';
t += ''+item.username+'<br>';
t += ''+item.date+'<br>';
t += '<button class="button2" type="button" id="'+item.id+'">Delete</button>';
t += '</div></div>';
t += ''+item.message+'<br><br>';
t += '</div>';
$('.comment_holder').prepend(t);
add_delete_handlers();
});
});
add_delete_handlers();
$('#postButton').click(function(){
comment_post_btn_click();
});
function comment_post_btn_click()
{
//text in textarea with username, page and date
var _username = $('#postUsername').val();
var _page = $('#postPage').val();
var _date = $('#postDate').val();
var _message = $('#postMessage').val();
if(_message.length > 0)
{
//proceed with ajax callback
$('#postMessage').css('border', '1px solid #ABABAB');
$.post("comment-set.inc.php",
{
task : "comment-set",
username : _username,
page : _page,
date : _date,
message : _message
}
).success(
function(data)
{
//Task: Insert html into the div
comment_set(jQuery.parseJSON(data));
console.log("ResponseText: " + data);
});
}
else
{
//text in area is empty
$('#postMessage').css('border', '1px solid #FF0000');
console.log("Comment is empty");
}
//remove text after posting
$('#postMessage').val("");
}
function add_delete_handlers()
{
$('.button2').each(function()
{
var btn = this;
$(btn).click(function()
{
comment_delete(btn.id);
});
});
}
function comment_delete(_id)
{
$.post("comment-del.inc.php",
{
task : "comment-del",
id : _id
}
).success(
function(data)
{
$('#_' + _id).detach();
});
}

$std->comment = $commentInfo;
echo json_encode($std);
}
}
?>
Picture of the problem (json_encode in the bottom of the picture containing 3 comments):

your comments div container has class .comment_holder so each time with new comment you prepend to all class's so create comment container with unique id an prepend to this. like this $('#comment_container').prepend(t); this with work.

PHP/HTML button picture change and script call

I have a page with buttons that a user clicks on.
When the button gets clicked I need it to change the image and call a php script to save the change.
I somehow can't get the button to do both, it changes the pic but won't call the php.
CODE:
<?php
$db = new PDO('mysql:host=localhost;dbname=MySettings;charset=utf8mb4', 'TestUser', '1234567890');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
try {
$mytable = $_SESSION["SESS_myuserid"];
if($mytable == null)
{$url='login.php';
echo '<META HTTP-EQUIV=REFRESH CONTENT="1; '.$url.'">';}
$stmt = $db->prepare("SELECT * FROM ".$mytable);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
$conn = null;
echo'<script>';
$count = count($result);
for ($i = 0; $i < $count; $i++) {
$TheId = $result[$i]['Id'];
$TheFunction = $result[$i]['TheFunction'];
$TheSetting = $result[$i]['TheSetting'];
if ($TheSetting == "0"){

}
echo'</script>';
$myLeft=0;
$myTop=0;
$myRow=0;

}
catch(PDOException $e) {

Fixed :
Changed the script function. Added a hidden div to be called to load the php which outputs nothing so stays invisible.
echo'<script>';

$TheId = $result[$i]['Id'];

when in the database search i have two result this code work properly but when the result is more than two the code doesnt work, i know the problem is about my variable in javascript but i have no idea to fix it , can any one help me to solve it??

PHP :
<?php mysql_connect('localhost','root',"");
mysql_select_db('geo-image');
$ARR_DATA = array();
$sql="SELECT * FROM images WHERE satellite='".$_POST["satellite"]."'";
$result=mysql_query($sql)or die(mysql_error());
while($rows = mysql_fetch_array($result)
{
$arr_temp['a'] = $rows['xpos'];
$arr_temp['b'] = $rows['ypos'];
$arr_temp['c'] = $rows['width'];
$arr_temp['d'] = $rows['height'];
$arr_temp['e'] = $rows['xoffset'];
$arr_temp['f'] = $rows['yoffset'];
$arr_temp['g'] = $rows['rotation'];
$arr_temp['h'] = $rows['resolution'];
$arr_temp['i'] = $rows['name'];
$arr_temp['j'] = $rows['url'];
$ARR_DATA[] = $arr_temp;
}
$count = count($ARR_DATA);
?>
JS :
<script>
<?php
foreach($ARR_DATA as $key=>$arr_temp)
{
?>
var a = "<?php echo $arr_temp['a'];?>";
var b = "<?php echo $arr_temp['b'];?>";
var c = "<?php echo $arr_temp['c'];?>";
var d = "<?php echo $arr_temp['d'];?>";
var e = "<?php echo $arr_temp['e'];?>";
var f = "<?php echo $arr_temp['f'];?>";
var g = "<?php echo $arr_temp['g'];?>";
var h = "<?php echo $arr_temp['h'];?>";
var i = "<?php echo $arr_temp['i'];?>";
var j = "<?php echo $arr_temp['j'];?>";
var img = "image/"+j+".jpg";
anArray[<?php echo $key;?>] = [ a, b, c, d, e, f, g, h, i, j];
<?php
}
?>
</script>

try
in php code
<?php mysql_connect('localhost','root',"");
mysql_select_db('geo-image');
$am=0 ;
$sql="SELECT * FROM images WHERE satellite='".$_POST["satellite"]."'";
$result=mysql_query($sql)or die(mysql_error());
$count = mysql_num_rows($result);
$images = array();
for ($i=1; $i<=$count; $i++)
{
$rows = mysql_fetch_array($result);
$images[] = $rows;
}
?>
in js code
<?php
foreach ($images as $image){
?>
anArray[anArray.length] = [ "<?php echo $image['xpos'];?>","<?php echo $image['ypos'];?>", "<?php echo $image['width'];?>", "<?php echo $image['height'];?>", "<?php echo $image['xoffset'];?>", "<?php echo $image['yoffset'];?>", "<?php echo $image['rotation'];?>", "<?php echo $image['resolution'];?>","<?php echo $image['name'];?>","image/<?php echo $image['url']?>.jpg"];
<?php
}
?>

the safiest way to communicate between php and js is to use json in my opinion. additionnaly, I would suggest you to use pdo or mysqli instead of mysql for the communication with your database.
