Data update without Page refresh after Select Query - php

Question

Kindly pardon me if i look silly mates.
My issue is , i have a profile page which on update and submit changes the data in db. To refresh the data then, i use select query after that. Then i save it in the current session. still the changes happens only in the page where the update and select query presents . I have some pages which is been included like top bar, left nav . which changes only if i refresh the page . My code is as follows
<?php
if(isset($_POST['update'])) {
$name_t = $_POST['name'];
$email_t = $_POST['email'];
$pass_t = $_POST['password'];
$contact_t = $_POST['contact'];
$address_t = $_POST['address'];
$dob_t = $_POST['dob'];
$religion_t = $_POST['religion'];
$pic_t = ($_FILES['imagefile']['name']);
$sql = "
UPDATE teacher
SET t_name = '$name_t'
, t_email = '$email_t'
, t_password = '$pass_t'
, t_phone = '$contact_t'
, t_address = '$address_t'
, t_dob = '$dob_t'
, t_religion = '$religion_t'
where teacher_id='$update_id'
";
$retval = mysql_query($sql,$link);
if(! $retval ) {
die('Could not update data: ' . mysql_error());
}
if (!empty($_FILES['imagefile']['name'])) {
$sql = "UPDATE teacher SET t_photo = '$pic_t' where teacher_id='$update_id' ";
$retval = mysql_query($sql,$link);
$info = pathinfo($_FILES['imagefile']['name']);
$ext = $info['extension']; // get the extension of the file
$target = 'img/upload/'.$pic_t;
move_uploaded_file( $_FILES['imagefile']['tmp_name'], $target);
}
}
$result = mysql_query("SELECT * FROM teacher where teacher_id='$update_id' ",$link);
while($row = mysql_fetch_array($result)){
$name = $row['t_name'];
$email = $row['t_email'];
$password = $row['t_password'];
$contact = $row['t_phone'];
$address = $row['t_address'];
$dob = $row['t_dob'];
$religion = $row['t_religion'];
$img = WEB_URL . 'img/upload/'.$row['t_photo'];
$_SESSION['objLogin'] = $row;
}
mysql_close($link);
?>
Kindly help me in updating the included page too without refresh . Because for instance there is the username displayed at top bar .
