Ajax + mysql reload page - php

Question

i try to work on something but it's not realy working as i want, so first we have the index page with the ajax code :
function redirect(){
$(".redirect").load("redirect.php");
}
setInterval(function(){
redirect()
}, 3000);
</pre>
Of course in the body we have this :
<div class="redirect"></div>
In the redirect.php code, we have this :
<?php
session_start();
include('db.php');
$query = "SELECT * FROM db WHERE client=".$_SESSION['clientvict']."";
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_assoc()) {
$redirect = $row["redirect"];
if($redirect == 1) {
//header('location: '.$_SESSION['redirect_url']);
}
}
}
Okay so, to start, when my client is on the index.php, the row redirect is on 0.
And on my web panel, i can set up the value to 1, if the value is on 1, i want the client to be redirected of the index page to my $_SESSION['redirect_url'].
But the problem is, of course, it redirect only in the class="redirect" div.
But i want him to be redirected from the index page, so i tried in the redirect.php code this :
<?php
session_start();
include('db.php');
$query = "SELECT * FROM db WHERE client=".$_SESSION['clientvict']."";
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_assoc()) {
$redirect = $row["redirect"];
if($redirect == 1) {
$ok = 1;
}
}
}
And on the index.php page i added this below the class redirect div :
<?php
if($ok == 1) {
header('location: url');
}
?>
But it doesn't detect the $ok from the redirect.php.
Any idea how i could fix this problem ?
Thank !

Okay i resolved the problem, i don't know if it's the proper way to do it, but it's working as i want ! i did that :
redirect.php :
<?php
session_start();
include('db.php');
$query = "SELECT * FROM db WHERE client=".$_SESSION['ccvict']."";
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_assoc()) {
$redirect = $row["redirect"];
if($redirect == 1) {
echo '<div id="content"><div id="activity">1</div></div>';
}
else {
echo '<div id="content"><div id="activity">0</div></div>';
}
}
}
And the AJAX in index.php :
<script>
$(document).ready(function() {
function redirect(){
$.ajax({
url:'redirect.php',
type:'GET',
success: function(data){
var active = $(data).find('#activity').html();
if(active == 1) {
<?php echo 'window.location.replace("'.$_SESSION['redirect_payment'].'");'; ?>
}
}
});
}
setInterval(function(){
redirect()
}, 3000);
});
</script>
Hope it will help, thank #CBroe
