Omitting blank fields in formmail results

[JDJones]

I have a form processing script that takes my form info and emails to
me. Pretty basic and it works. But I'd like to be able to have it not
print a form variable if the value is empty. I know about using
if $($incoming_fields[$i] = "") {
to find the empty value. I'm just not sure about how to tell it to not
print the empty ones in the results. Can anyone help? Thanks.
Below is the current info used to populate the email sent to me:

//GET POST INFO
$incoming_fields = array_keys($_POST);
$incoming_values = array_values($_POST);

// LOAD EMAIL CONTENTS
for ($i = 0; $i < count($incoming_fields); $i++) {
if($incoming_fields[$i] != "rec_mailto") {
if($incoming_fields[$i] != "rec_subject") {
if($incoming_fields[$i] != "rec_thanks") {
if($incoming_fields[$i] != "opt_mailto_cc") {
if($incoming_fields[$i] != "opt_mailto_bcc") {
// ADD FIELD TO OUTGOING MESSAGE
$message .= "$incoming_fields[$i]: $incoming_values[$i]\n";
}}}}}}

Replace your 'ADD FIELD' line above with something like:
if ($incoming_fields[$i] != '')
$message .= "$incoming_fields[$i]: $incoming_fields[$i]\n";

HTH =)

foreach($_POST as $field => $value){

if((!preg_match("/^(rec_(mailto|subject|thanks)|opt_mailto_(bcc|cc)) $/",
$field)) && empty($field) == false){
$message .= "$field: $value\n";
}
}

This should work, smaller code, and faster (I think).
