    foreach($data as $field => $value){
        $messageData .= "$field: $value \n";
    }
 
    sendmail(array(
        'to' => 'employee@company.com',
        'name' => 'Recipient Name',
         
        'subject' => 'A new record needs your attention',
         
        'message' => "The following new record was submitted by {$memberInfo['username']}: \n\n" . $messageData
