Need Confirmation Message to Remain on Page Options

[chome4]

I have a working php contact form:

<?php
$msg = "";
use PHPMailer\PHPMailer\PHPMailer;
include_once "PHPMailer/PHPMailer.php";
include_once "PHPMailer/Exception.php";
include_once "PHPMailer/SMTP.php";

if (isset($_POST['submit'])) {
$subject = $_POST['subject'];
$email = $_POST['email'];
$message = $_POST['message'];

$mail = new PHPMailer();

//if we want to send via SMTP
$mail->Host = "smtp.34sp.com";
//$mail->isSMTP();
$mail->SMTPAuth = true;
$mail->Username = "email";
$mail->Password = "password";
$mail->SMTPSecure = "ssl"; //TLS
$mail->Port = 465; //587

$mail->addAddress('email');
$mail->setFrom($email);
$mail->Subject = $subject;
$mail->isHTML(true);
$mail->Body = $message;
//$mail->addAttachment($file);

if ($mail->send())
echo "<h1>Sent Successfully! Thank you"." ".$name.", We will contact you shortly!</h1></br>
Use the 'back' arrow to go back to the main page...";
else
echo "Something went wrong!";
}
?>

The confirmation message is echoed out to a new, white page. Still getting to grips with php, but I cannot work out how to get the confirmation message to appear above the form instead of appearing on a new page.

This is the form's code

<form method="post" action="contact.php" enctype="multipart/form-data">
<input name="subject" placeholder="Subject..."><br>
<input name="email" type="email" placeholder="Email..."><br>
<textarea placeholder="Message..." name="message"></textarea><br>
<input name="submit" type="submit" value="Send Email">
</form>



Any ideas?

Hope someone can help.

I had some time so I put together an example page. You will have to adjust the code to fit your logic but it should get you going.
The form has 1 input, leave it blank and click Submit. An error message will now appear above the form.
Next, type some text into the input and click Submit. A success message will now appear above the form and the form will be blank.

Working on it....

Incorporating it into the existing page is giving some formatting issues but will let you know when it's behaving itself.....
