Mailer - going back to previous page

I'm trying to use the above form mailer for my site. It works fine as intended except it doesn't refer me back to the page where I previously was. Rather it sends me back to the mailer form after the message has been sent. How can I have it configured to return to the actual previous page. I suppose I need to have define a variable and set the variable to read $HTTP_REFERER on the mailer form and then have the variable stored (perhaps written to a text file). The stored value would then be read at the message sent page where it will redirect me back to the correct page. What codes should I put in? Thanks.

First of all, I would put it all on one page and make it self posting. I haven't worked much with HTTP_REFERRER but the browser does not always provide one. You need to define a default value depending on your site to populate the URL with if no referrer is provided. I would also put a loop at the top of the page in case globals get turned off, then gather the referrer and populate the form with it. I have not tested this on my system but here is an example of how I would start to approach it:

<?php
foreach($_POST as $key => $val){
	$$key=$val;
}
if(!isset($email)){ // email is required
	$return=$HTTP_REFERER;
?>

<form method='post'>
<input type='hidden' name='return' value='<?php echo $return; ?>'>

//finish the table and the rest of the contact.php

<?php
}else{

//all the mail stuff here (mail.php)

echo("Your mail has been sent.<br><br>".
	"<a href=\"".$return."\">go back.</a>\n");
}
?>
