JS Code

function SubmitForm(e) {
e.preventDefault();
var game = $("#game").val();
var question = $("#question").val();
var option = $("#option").val();
$.post("submit.php", { game: game, question: question, option: option },
}

submit.php Code

<?php
//Include configuration file
include('includes/config.php');

//Define variables
$question=$_POST['question'];
$game=$_POST['game'];
$option=$_POST['option'];
$choice=$_POST['choice'];

//Generate random number
$rand_value=rand();

//Create temporary folder
mkdir($rand_value);

//Copy page of Ask Poll
copy('page.php', $rand_value . '/page.php');
rename($rand_value . '/page.php', $rand_value . '/index.php');

//Add data into database
mysql_connect($db_host, $db_username, $db_password) or die ("Errore di connessione!");
mysql_select_db($db_name) or die ("Impossibile selezionare database!");
$sql1="CREATE TABLE `" . $rand_value . "` (Question VARCHAR(200), Options VARCHAR(200), Choice INT(11))";
mysql_query($sql1) or die ("Impossibile eseguire la query!");

//Count number of Options available
$count=count($option);

    for ($i=0; $i<($count-1); $i++)
    {
        ${$sql . $i}="INSERT INTO `" . $rand_value . "` (Question, Options, Choice) VALUES ('$question', '$option[$i]', '$choice')";
        mysql_query(${$sql . $i});
    }   
?>

All works perfectly but the only problem is that when i click Create Poll button, the browser redirect me to submit.php blank page

UPDATE

This code doesn't work

function SubmitForm(e) {
e.preventDefault();
var game = $("#game").val();
var question = $("#question").val();
var option = $("#option").val();
$.post("submit.php", { game: game, question: question, option: option }
return false;
}

Can you write me an AJAX function as the last comment says?

You can just add onsubmit="return false;" to your form:

<form onsubmit="return false;">
*****
****
</form>

use Ajax function if you want that the page doesn't refresh on click the "Create Poll" button. It loads the part of the page without refresh the whole page.

Either place return false; at the end of the function SubmitForm or change onclick="SubmitForm();" to onclick="SubmitForm(); return false;"

place return false; at the end of your SubmitForm function and loose the comma at the end of the last sentence

function SubmitForm(e) {
  e.preventDefault();
  var game = $("#game").val();
  var question = $("#question").val();
  var option = $("#option").val();
  $.post("submit.php", { game: game, question: question, option: option }
  return false;
}
