<?php


$phpmailmsg="Datos del Usuario:\n\n"; // beginning of email message

reset ($HTTP_POST_VARS); // reset the array pointer to the beginning, just in case
while (list ($key, $val) = each ($HTTP_POST_VARS)) {
$phpmailmsg=$phpmailmsg."$key: $val\n"; // add each key and value (html input name and value) to message
}

reset ($HTTP_GET_VARS); // same as above, except with the GET vars (to support both methods)
while (list ($key, $val) = each ($HTTP_GET_VARS)) {
$phpmailmsg=$phpmailmsg."$key: $val\n";
}



mail ("$to", "$subject", "$phpmailmsg", "From: [email protected]" ); // send the email to the variable specified in 'to', with the 'subject' and message ('phpmailmessage')
//mail ("$to", "$subject", "$phpmailmsg", "$email\n" );


if ($redirect) header("Location: $redirect"); // if there is a redirect page specified, redirect to it

//echo "Thank you for submitting your info!"; // if not, write this to the page (modify the text between the "s to suit your needs)

?>
