    Hey there,

    I recently came accross a php code that logs all info submitted into all text boxes on a webpage.

    $handle = fopen("log.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
    Code (markup):
    Its going to be a registration form that will be asking questions.

    Presuming that username is the variable for username

    and fav_game is the variable for favorite game.


    How would I log these parts of the webpage rather than all of it.

$handle = fopen("log.txt", "a");
fwrite($handle, "username=".$_POST['username']);
fwrite($handle, "\r\n");
fwrite($handle, "\r\n");
fwrite($handle, "fav_game=".$_POST['fav_game']);
fwrite($handle, "\r\n");
fwrite($handle, "\r\n");
fclose($handle);
    PHP:
    Or if you wish to add some more fields to log in future
    
$fields = array('username','fav_game');
$handle = fopen("log.txt", "a");
foreach($fields as $variable) {
  if(!isset($_POST[$variable])) continue;
  fwrite($handle, $variable);
  fwrite($handle, "=");
  fwrite($handle, $_POST[$variable]);
  fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
