Question

我有一个AJAX函数，它从提交表单中获取数据，并且应该将变量传递给process.php

index.html是主页

    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <script type="text/javascript" src="js/bootstrap.js"></script>
    <script type='text/javascript' src='js/addfield.js'></script>
    <script type='text/javascript' src='js/changebackground.js'></script>
    <script type='text/javascript' src='magic.js'></script>
</body>
</html>

这是magic.js文件

$(document).ready(function() 
{
$("#submit_button").click(function() 
{
    var game = $("#game-group:selected").val();
    var question = $("#question").val();
    var option = $("#option[]").val();
    var choice = $("#choice").val();

    if (game == '' || question == '' || option == '' || choice == '') 
    {
        alert("Insertion Failed Some Fields are Blank....!!");
    } 
    else 
    {
        // Returns successful data submission message when the entered information is stored in database.
        $.post("process.php", {
        game1: game,
        question1: question,
        option1: option,
        choice1: choice
        },
        function(data) 
        {
            alert(data);
            $('#form')[0].reset(); // To reset form fields
        });
    }
});
});

这是process.php文件

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

//Define variables
$game2=$_POST['game'];
$question2=$_POST['question'];
$option2=$_POST['option'];
$choice2=$_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 `" . $rand_value . "` (Question, Options, Choice) VALUES ('$question2', '$option2[$i]', '$choice2')";
    mysql_query(${$sql . $i});
}   
?>

问题是AJAX功能没有将数据传递给process.php，实际上我没有看到任何文件夹进入我的服务器或数据保存到数据库中

Answer 1

变化

var option = $("#option[]").val();

到

var option = $("#option").val();

您已在ID选择器中分配[]运算符

Answer 2

您的javascript属性名称与您的php数组键不匹配：

{
    game1: game,
    question1: question,
    option1: option,
    choice1: choice
}

$game2=$_POST['game'];
$question2=$_POST['question'];
$option2=$_POST['option'];
$choice2=$_POST['choice'];

改变其中一个，例如：

{
    game: game,
    question: question,
    option: option,
    choice: choice
}

Answer 3

我看到的唯一问题是在你的php中调用POST vars时，你需要使用对象中的键名。不是变量名。

//Define variables
$game2=$_POST['game1'];
$question2=$_POST['question1'];
$option2=$_POST['option1'];
$choice2=$_POST['choice1'];

希望这有帮助！
