SQL Form submit result - php

Question

I want to display a message something like: "Congrats! you have been registered".
But the message appears on the top left corner of the page. I want to display it in the same page below the "Submit Button".
Here's my code:
if($result)
{
//send the email
$to = "xyz#abc.com";
$subject = "New order for Weaving Hope";
//headers and subject
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: ".$name." <".$email.">\r\n";
$body = "New contact<br />";
$body .= "Name: ".$name."<br />";
$body .= "Email: ".$email."<br />";
$body .= "Contact No.: ".$contact."<br />";
$body .= "Item Id: ".$itemid."<br />";
$body .= "Quantity: ".$itemquantity."<br />";
$body .= "Comment: ".$comment."<br />";
$body .= "IP: ".$ip."<br />";
mail($to, $subject, $body, $headers);
//ok message
echo "Congrats!";
}

Answer 2

If you need to do this without AJAX, then you need to process the form data in the same PHP page that sends the form to the browser, and set a flag to determine whether or not the data submission was successful.
For example:
<?php // Call this page register.php
$success = false;
if( $result)
{
// .. Your code from above
$success = true;
}
?>
<form action="register.php" method="post">
<!-- Output the form for submission here -->
<input type="submit" name="register" value="Register" />
<?php if( $success): ?>
<span>Congrats, you are registered!</span>
<?php endif; ?>
</form>
