On my website i have a submit form:

When i press this submit button the name is being saved on to my database, which is fine but i also want that button to take me to the homepage. Right now it take me to a page saying Fatal error like this

But when i press on the URL link and press enter it take me to the homepage. How can i redirect the page to homepage without selecting/pressing on the URL link and hitting enter? This is my code:

IMG:

CODE:

<?php
  require_once "library/connection.php";
  $stmt = $conn->prepare("SELECT * FROM usernames ORDER BY scores DESC LIMIT 10");
  function createLeaderBoard($stmt)
  {
    $stmt->execute();
    $stmt->rowCount();
    $data = $stmt->fetchAll();
    foreach ($data as $row) 
    {
?>
       <tr>
          <td><?php echo $row['users']; ?></td>
          <td><?php echo $row['Scores']; ?></td>
       </tr>
<?php
    }
  }
  if (isset($_POST["firstname"])) 
  {
     $firstname = $_POST["firstname"];
     $score     = $_POST["score"];
     $stmt      = $conn->prepare("INSERT INTO `usernames` (`users`, `Scores`)     VALUES ('" . $firstname . "','" . $score . "');");
     $stmt->execute();
     $result = $stmt->fetch(PDO::FETCH_ASSOC);
  }
?>

Hope my English is good and i also hope you can understand me. All the help will be appreciated :)
