title: php contact form sending blank emails sometimes
body: <p>I've gone thru tons of the forms and cant seem to find the answer. I have been working on this problem with my php form on and off for days. hope to find help here. the form is working perfect. all the fields are working correct upon submit, but there always seems to be a second form sent out from a day to two days later that is blank. If there is any suggestions to why this occurs it would be helpful. </p>
  
  <pre><code>&lt;?php
  
  
  $name = $_POST['name'];
  $email = $_POST['email'];
  $subject = $_POST['subject'];
  $comments = $_POST['comments'];
  
  // recipient address
  $to = "grandforkssuites@gmail.com";
  
  // subject of email
  $re = "Contact Us Form Delivery";
  
  // message creation
  $contact = "Name:".$name."\nEmail:".$email."\nSubject:".$subject."\r\n";
  
  $txt = "Comments:".$comments."\r\n";
  
  
  $fmsg = $contact."\r\n".$txt;
  
  $msg = wordwrap($fmsg, 70);
  
  // send email
  mail($to,$re,$msg);
