Well you can basically copy and paste your HTML code for your form and place it into a var on the post page (you would need to get rid of the form elements and use the post vars though)
//####################################################################################
//####################################################################################
//now we build our email
$to = //the to EmailAddress goes here
$subject = //what appears in the subject line of the email goes here
$header = "From: <From email address goes here>\nMIME-Version: 1.0\r\n";
$header .= "Content-type: text/html; charset=iso-8859-1\r\n";//leave alone
$message = "This is where your HTML code would go to display your form results";
//**************************************** email ***********************************************************
$from = " '-fFromEmail' ";//leave the -f put the from email address after it without spaces
mail($to, $subject, $message, $header,$from)//put any error trapping code here if you like
//****************************************end of email *******************************************************
Hope this helps
