I am working on a profile page for users and would like to give them the option of adding an avatar or profile image. The code I am using is not working. Images are not being moved into the tmp folder named "avatars." Not sure how to fix! Here is my code:

<?php
include("functions/globals.php"); 
include("databasefunctions.php");
include("functions/userfunctions.php"); 
?>

<?php session_start(); ?>

<?php
if($_SESSION['user'])
{?>
                      
Welcome: <?php echo $_SESSION['user']->username; ?>
                <?php
                      }?>
                      
                      
<?php

if($_POST['submit'] == 'Upload')
{
//get file attributes
$name = $_FILES['avatar']['name'];
$tmp_name = $_FILES['avatar']['tmp_name'];
$location = "avatars/$name";

if ($name)
{
//start upload process


move_uploaded_file($tmp_name,$location);

$result = mysql_query("UPDATE users SET imagelocation='$location' WHERE username='$username'");

die("Your avatar has been uploaded <a href='view.php'>Home</a>");
}
	else
	if(!$name)
$error = "Please select an image";

}


?>
<form action='profile.php' method='post' enctype='multipart/form-data'>
Upload:<input type='file' name='avatar'><input type='submit' name='submit' value='Upload'>
</form>

I also added this before move_uploaded_file:

echo '<pre>';
print_r($_FILES);
echo '</pre>';

This is what returned:

Array
(
[avatar] => Array
(
[name] => me.jpg
[type] => image/jpeg
[tmp_name] => /var/tmp/phpFZKL9d
[error] => 0
[size] => 35433
)

)

Any ideas???
