Register.php....Need Help

[cc9of13]

Hello again. I am a web development student, currently studying PHP. I've been trying to get this script to work correctly for days and still no luck. I'm not sure if my issue is with the script or maybe a php.ini setting related to the mail server. Anyway, this is a simple registration form. It accepts input and adds it to the DB, but it does not send the activation email or redirect me to "thanks for registering page. Does anyone have any input? I truly appreciate it!

 

<?php // register.php

// Include the configuration file for error management and such.
require_once ('./includes/config.inc.php');
// Set the page title and include the HTML header.
$page_title = 'Register';
include ('./includes/header.html');

// Handle the form.
if (isset($_POST['submitted'])) { 
    // Connect to the database.
    require_once ('includes/mysql_connect.php');
    
    // Check for a first name.
    if (preg_match("/^[A-Za-z’ -]{2,15}$/i", stripslashes(trim($_POST ['first_name'])))) {
        $fn = escape_data($_POST ['first_name']);
    } else {
        $fn = false;
        echo '<p><font color="red" size="+1">Please enter your first name!</font></p>';
    }  
    // Check for a last name.
        if (preg_match("/^[A-Za-z’ -]{2,30}$/i", stripslashes(trim($_POST ['last_name'])))) {
            $ln = escape_data($_POST ['last_name']);
        } else {
            $ln = false;
            echo '<p><font color="red" size="+1">Please enter your last name!</font></p>';
        }
    // Check for an email address.
        if(preg_match("/^.+@.+\\..+$/i", stripslashes(trim($_POST ['email'])))) {
            $e = escape_data($_POST['email']);
        } else {
            $e = false;
            echo '<p><font color="red" size="+1">Please enter a valid email address!</font></p>';
        }
    // Check for a password and match against the confirmed password.
        if (preg_match("/^[a-z0-9]{4,20}$/i", stripslashes(trim($_POST ['pass'])))) {
            if ($_POST['pass'] = $_POST['pass2']) {
                $p = escape_data($_POST ['pass']);
            } else {
                $p = false;

            }
        } else {

            echo '<p><font color="red" size="+1">Please enter a valid password!</font></p>';
        }

      // Make sure the email address is available.
      $query = "SELECT user_id FROM users WHERE email='$e'";
      $result = mysql_query ($query) or trigger_error("Query: 
      $query\n<br/>MySQL Error: " . mysql_error());
      if (mysql_num_rows($result) == 0) {

        // Add the user.
        $query = "INSERT INTO users (email, pass, first_name, last_name, active, registration_date) VALUES ('$e', SHA('$p'), '$fn', '$ln','$a', NOW() )";
        $result = mysql_query ($query) or trigger_error("Query: $query\n<br/>MySQL Error: " . mysql_error());
           if (mysql_affected_rows()== 1) {
             // Send the email.
