提交.php代码
<?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
一切正常，但唯一的问题是，当我单击“创建投票”按钮时，浏览器将我重定向到 submit.php 空白页面
UPDATE
更新
This code doesn't work
此代码不起作用
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?
你能像最后一条评论所说的那样给我写一个 AJAX 函数吗？
回答by Wezy
place return false;at the end of your SubmitFormfunction and loose the comma at the end of the last sentence
放置return false;在你的结尾SubmitForm功能，并在最后一句的结尾松逗号
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;
}

Either place return false;at the end of the function SubmitForm or change onclick="SubmitForm();"to onclick="SubmitForm(); return false;"
放在return false;函数 SubmitForm 的末尾或更改onclick="SubmitForm();"为onclick="SubmitForm(); return false;"
回答by Pooya Behravesh
You can just add onsubmit="return false;" to your form:
你可以添加 onsubmit="return false;" 到您的表格：
<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.
如果您希望页面在单击“创建投票”按钮时不刷新，请使用 Ajax 功能。它加载页面的一部分而不刷新整个页面。
