I have this code in all the pages of my web to display the username.
<p>Welcome <?php echo $_SESSION['username']; ?>!</p>
And i allow users to update their username, but when they update it. It won´t update the session variable, the user have to re-login to see the changes. There is any way to update it without re-login?
Here is the code I´m using to update
<?php
include_once 'db_connect.php';
include_once 'functions.php';
sec_session_start();
echo $_SESSION['username'];
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Secure Login: Protected Page</title>
<link rel="stylesheet" href="styles/main.css" />
</head>
<body>
<?php if (login_check($mysqli) == true) : ?>
<p>Welcome <?php echo htmlentities($_SESSION['username']); ?>!</p>
<a href="logout.php">Log out</a>
<?php
mysql_connect("localhost","root");
mysql_select_db("userdata");
$sql_query="SELECT * FROM users";
$result_set=mysql_query($sql_query);
?>
<?php
if(isset($_GET['user_id']))
{
$result_set=mysql_query($sql_query);
$fetched_row=mysql_fetch_array($result_set);
}
if(isset($_POST['btn-update']))
{
// variables for input data
$username = $_POST['username'];
$email = $_POST['email'];
$user_id = $_SESSION['user_id'];
// variables for input data
// sql query for update data into database
$sql_query = "UPDATE users SET username='$username',email='$email' WHERE id= '$user_id'";
// sql query for update data into database
// sql query execution function
if(mysql_query($sql_query))
{
?>
<script type="text/javascript">
alert('Data Are Updated Successfully');
window.location.href='publish_page.php';
</script>
<?php
}
else
{
?>
<script type="text/javascript">
alert('error occured while updating data');
</script>
<?php
}
// sql query execution function
}
if(isset($_POST['btn-cancel']))
{
header("Location: publish_page.php");
}
?>

<?php endif; ?>

I already tried to delete cache and didn´t solve. Any ideas how i can update it automatically?
