  109. Another method for filtering after the submit might look like the following. Be sure to change $_POST to $_GET if you are using that method.
  110.  
  111. foreach( $_POST as $value ){
  112. if( stripos($value,'Content-Type:') !== FALSE ){
  113. mail('[email protected]','Spammer Bot Attempt',$_SERVER['REMOTE_ADDR']);
  114. exit("{$_SERVER['REMOTE_ADDR']} Has been Recorded");
  115. }
  116. }
