PHP/MySQL "Quiz"游戏 - 表单输入值

好的,所以我已经为此工作了两天 - 我的代码有些草率和困惑,但我已经检查了数百个问题、网站等。寻找答案或简单的解释我了解;不幸的是,我的尝试仍然没有成功。

我正在用 PHP/HTML 构建一个“测验”游戏 - 该网站引用了一个数据库,特别是一个标有“答案”的表格,其中包含以下信息:

 - ID: Auto-Increment
- Question: Varchar
- Answer: Varchar
- Comment: Varchar

现在,关于该站点的一些信息 - 一旦用户登录,他/她就可以“玩”游戏;该游戏只是一个 HTML 表单,在其上方显示一个随机的“答案表”问题。该表单有 4 个用户输入,但只需要两个。让我进入代码细节,然后我会问我的问题:

我的 index.php 页面(包含游戏表单)当前是:

<?php # index.php
session_start();
//check session first
if (!isset($_SESSION['email'])){
include ('../includes/header.php');
}else
{
session_start();
include ('../includes/header.php');
require_once ('../../mysql_connect.php');
$query = "SELECT * FROM answers ORDER BY RAND() LIMIT 1";
$result = @mysql_query ($query);
$num = mysql_num_rows($result);
if ($num > 0) { // If it ran OK, display all the records.
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
?>

<div class="newGame">
<h2>Are you a Question Master?<hr /></h2>
<h3 style="color:#000">Find Out Now!</h3>
</div>
<br />

<div class="newGameContain">
<form action="gameSubmit.php" method="post" autocomplete="off">
<h2><? echo $row["Question"]."<hr />"; ?></h2>
<h3>Enter Player Answers</h3>
<p><input type="text" placeholder="Player 1" name="player1" value="<? echo $_POST['player1']; ?>" /> <input type="text" placeholder="Player 2" name="player2" value="<? echo $_POST['player2']; ?>" /></p>
<p><input type="text" placeholder="Player 3" name="player3" value="<? echo $_POST['player3']; ?>" /> <input type="text" placeholder="Player 4" name="player4" value="<? echo $_POST['player4']; ?>" /></p>
<p><input type="submit" class="submitButton" /> <input type="reset" class="resetButton" value="Reset" /> </p>
<input type="hidden" name="ID" value="<?php echo $row["ID"]; ?>" />
<input type="hidden" name"Answer" value="<?php echo $row['Answer']; ?>" />
<input type="hidden" name="submitted" value="TRUE" />
</form>
<p></p>
</div>
<br />


<?php
} //end while statement
} //end if statement
mysql_close();
//include the footer
include ("../includes/footer.php");
}
?>

然后我的 gameSubmit.php 页面(表单操作)看起来像这样 - 我只会给出一个快照,而不是整个内容:

 <?php # index.php
session_start();
//check session first
if (!isset($_SESSION['email'])){
include ('../includes/header.php');
}else
{
session_start();
include ('../includes/header.php');
require_once ('../../mysql_connect.php');
$query = "SELECT * FROM answers ORDER BY RAND() LIMIT 1";
$result = @mysql_query ($query);
$num = mysql_num_rows($result);
if ($num > 0) { // If it ran OK, display all the records.
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
?>

<? if (isset($_POST['submitted'])){

$correct1Msg = "<div class='correct1Msg'><p style='color:#000;font-family:Arial, Helvetica, sans-serif;'>Player 1 entered the <span id='answerUnder'>correct answer</span>.</p></div><p></p>";
$correct2Msg = "<div class='correct2Msg'><p style='color:#000;font-family:Arial, Helvetica, sans-serif;'>Player 2 entered the <span id='answerUnder'>correct answer</span>.</p></div><p></p>";

$incorrect1Msg = "<div class='incorrect1Msg'><p style='color:#F00;font-family:Arial, Helvetica, sans-serif;'>Player 1 entered the <span id='answerUnder'>incorrect answer</span>.</p></div><p></p>";
$incorrect2Msg = "<div class='incorrect2Msg'><p style='color:#F00;font-family:Arial, Helvetica, sans-serif;'>Player 2 entered the <span id='answerUnder'>incorrect answer</span>.</p></div><p></p>";

$player1Answer = $_POST['player1'];
$player2Answer = $_POST['player2'];
$player3Answer = $_POST['player3'];
$player4Answer = $_POST['player4'];

$questionID = $row['ID'];

if ($questionID == "1" && $player1Answer != "Red"){
echo $incorrect1Msg;
}elseif ($questionID == "2" && $player1Answer != "4"){
echo $incorrect1Msg;
}else {
echo $correct1Msg;
}

if ($questionID == "1" && $player2Answer == "Red"){
echo $correct2Msg;
}elseif ($questionID == "2" && $player2Answer == "4"){
echo $correct2Msg;
}else{
echo $incorrect2Msg;
}
}
?>

<?php
} //end while statement
} //end if statement
mysql_close();
//include the footer
include ("../includes/footer.php");
}
?>

请注意,gameSubmit.php 页面也有相同的消息和 if...elseif... player3Answer 和 player4Answer 的语句。

所以我的问题是...

如果用户登录并打开 index.php 页面,系统会提示他/她“echo $row ["Question"]”(这是一个使用 $query = "SELECT 从 MySQL 数据库中提取的问题* FROM answers ORDER BY RAND() LIMIT 1"; - 然后用户继续在每个玩家各自的文本输入中输入答案。一旦用户单击提交按钮,表单将重定向到 gameSubmit.php - 一旦加载,如果(isset ($_POST['submitted'])){ 启动并交叉检查每个用户的回答并显示相应的消息。

目前,我的表单重定向到 gameSubmit.php,但是,它没有引用上一个问题的正确答案 - 因此,在对答案进行“评分”时出现完全相同的答案真是太幸运了。

为了在表单操作页面上实现输入验证,我需要做什么/需要更正什么?

再一次,我只是想随机检索一个问题并在提交时检查输入的答案是否正确 - 我还希望我的代码能够检索正确答案而不是我必须输入每个答案,这样一来,如果添加了一条记录,我就不必更新代码。

感谢您的宝贵时间和帮助,非常感谢! (这是期末考试周,我的压力再大不过了)

最佳答案

只需将带有问题 ID 的 POST 元素从索引页面传递到 gameSubmit.php。

在索引页中添加一个隐藏元素,例如..

<input type="hidden" name="questionId" value="<?php echo $row['id']; ?>">

因此,您可以使用 $_POST['questionId']

在 pageSubmit.php 中获取问题 ID
