"from" in a form mail script

[glennn]

how can i get a form to return a "from" field in something like this script, please, someone:

// SET VARIABLES
$incoming_fields = array_keys($POST);
$incoming_values = array_values($POST);

if($override == "no") {
$incoming_mailto = @$POST['rec_mailto'];
$incoming_subject = @$POST['rec_subject'];
$incoming_thanks = @$_POST['rec_thanks'];
}

?

glennn, you're probably going to have to be a little more specific. Are you trying to create a from field for an email the script is going to send? If so, and assuming you're trying to create the usual -- something like a feedback form, you should probably set it yourself.
