how do i send a user message to their mail from phpmailer? - php

Question

Hi guys, please I'm having problem with my code. I want to accept user
email and verify it from my database then send the user an email using
PHPMailer but it's giving me error, I guess I did some bunch of error
coding here. please how do I go about it? this question might be silly
but I really need assistance from anyone, please. Thanks.
here is what I've tried out.
<?php
require 'PHPMailer/PHPMailerAutoload.php';
$con = mysqli_connect("localhost","root","password007","voting");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
// username and password sent from form
$email = mysqli_real_escape_string($con,$_POST['email']);
$sql = "SELECT VotersID,Email,First_name FROM voters WHERE Email = '$email' ";
$result = mysqli_query($con,$sql);
$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
$count = mysqli_num_rows($result);
$votersID = $row['VotersID'];
$first = $row['First_name'];
if($count == 1) {
$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = '******#gmail.com';
$mail->Password = '*******';
$mail->SMTPSecure = 'tls';
$mail->Port = '587';
$mail->From = '*****#gmail.com';
$mail->FromName = 'West End University College';
$mail->addAddress($email, $first);
$mail->addReplyTo('*****#gmail.com', 'West End University College');
$mail->WordWrap = 50;
$mail->isHTML(true);
$mail->Subject = 'code for login Confirmation';
$mail->Body = 'Hi, your code is:';
$mail->addAttachment($votersID);
}
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
exit;
}
else{
echo "Message sent successfully";
}
}
?>
