PHPMailer sending to blank page - php

Question

I am trying to get PHPMailer to work to send mail from form data(obviously).
ISSUE:
When submitting form, I am getting sent to a blank page. No errors are being reported. I have followed as many stackoverflow threads surrounding this issue as I could find, and no solutions in those threads resolved the issue for myself.
Thanks
ERRORS:
Fixed all errors aside from: 2016-03-26 22:10:43 SMTP ERROR: Failed to connect to server: Connection refused (111) 2016-03-26 22:10:43 SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

require 'PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer();
$mail->SMTPDebug = 2; // Enable verbose debug output

$mail->CharSet = 'UTF-8';

Answer 1

You need to redirect the header back to the form (I assume that is where you want to send them) Replace the location inside the header with your URL
<?php
$message=
'First Name: '.$_POST['first'].'<br />
Last Name: '.$_POST['last'].'<br />
Phone: '.$_POST['phone'].'<br />
Email: '.$_POST['email'].'<br />
Message: '.$_POST['message'].'
';
require 'PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer();
$mail->SMTPDebug = 2; // Enable verbose debug output
$mail->IsSMTP(); // Sets up a SMTP connection
$mail->CharSet = 'UTF-8';
$mail->SMTPAuth = true; // Connection with the SMTP does require authorization
$mail->SMTPSecure = "tls"; // Connect using a TLS connection
$mail->Host = "smtp.gmail.com"; //Gmail SMTP server address
$mail->Port = 587;
// Authentication
$mail->Username = "xxxx#gmail.com"; // Your full Gmail address
$mail->Password = "xxxx"; // Your Gmail password
// Compose
$mail->SetFrom($_POST['email'], $_POST['firstname'] . ' ' . $_POST['lastname']);
$mail->AddReplyTo($_POST['email'], $_POST['firstname'] . ' ' . $_POST['lastname']);
$mail->Subject = "New Contact Form Enquiry"; // Subject (which isn't required)
$mail->MsgHTML($message);
// Send To
$mail->AddAddress("xxxx#gmail.com", "xxxx"); // Where to send it - Recipient
$result = $mail->Send(); // Send!
if ($result)
{
header("Location: : http://www.example.com/contactform.php");
}
else {
echo "sending mail failed: " . $mail->ErrorInfo;
}
unset($mail);
}
?>

You should make sure there are no errors. Try placing this code at the top of your file to make sure all errors/warnings are reported and run the script again.
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(E_ALL);
