Displaying user input from a form in verification email
<p>I'm having a little problem with my registration form: I am trying to get the UserID field displayed as inputted by the user when the verification email is sent for the user to activate the account.
Currently, I only need the <em>User provided</em> UserID and <em>randomly generated</em> PIN to be displayed in the verification email. Please can anyone correct this for me, as the PIN is displayed properly in the email, but not the UserID.</p>

<p>Below is my code:</p>

<pre><code>&lt;div id="wrap"&gt;
        &lt;!-- start PHP code --&gt;
        &lt;?php

            mysql_connect("localhost", "root", "") or die(mysql_error()); // Connect to database server(localhost) with root .
            mysql_select_db("registrations") or die(mysql_error()); // Select registration database.

            $email="";

            if( isset($_POST['fullname']) // Is the name field being posted; it does not matter whether it's empty or filled.  
    &amp;&amp; // This is the same as the AND in our statement; it allows you to check multiple statements.  
    !empty($_POST['fullname']) // Verify if the field name is not empty 
    AND isset($_POST['email']) // Is the email field being posted; it does not matter if it's empty or filled.  
    &amp;&amp; // This is the same as the AND in our statement; it allows you to check multiple statements.  
    !empty($_POST['email']) ) // Verify if the field email is not empty   
      {

                $fullname = mysql_real_escape_string($_POST['fullname']);
                $email = mysql_real_escape_string($_POST['email']);

                }
                if(!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/", $email)){
                    // Return Error - Invalid Email
                    $msg = 'The email you have entered is invalid, please try again.';
                }else{
                    // Return Success - Valid Email
                    $msg = 'Your account has been created, &lt;br /&gt; please verify it by clicking the activation link that has been send to your email.';
                    }

                    $hash = md5( rand(0,1000) ); // Generate random 32 character hash and assign it to a local variable.

                    $PIN = rand(1000,5000); // Generate random number between 1000 and 5000 and assign it to a local variable.

$to      = $email; // Send email to our user  
$subject = 'Signup | Verification of your BFS Account'; // Give the email a subject  
$message = 'Thanks for signing up! 
Your account has been created, you can login with the following credentials after you have activated your account by clicking the url below. 
------------------------ 
USER ID: '.$UserID.' // **THIS IS WHERE I HAVE THE PROBLEM DISPLAYING USER ID**

$headers = 'From:noreply@website.com' . "\r\n"; // Set from headers  
mail($to, $subject, $message, $headers); // Send our email  

        ?&gt;
        &lt;!-- stop PHP Code --&gt;           

    &lt;/div&gt;
