PHP / MySQL“测验”游戏 - 表单输入值

好吧,所以我现在已经做了两天了 - 我的代码有些草率和混乱,但我已经超过了数百个问题,网站等等寻找答案或只是我理解的解释;不幸的是,我的尝试仍未成功。

我在PHP / HTML中构建一个“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,有关网站上的一些信息 - 一旦用户登录,他/她就可以“玩”游戏;游戏只是一个HTML表单,上面显示一个随机的“答案表”问题。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)目前是:

<?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,而不是整个事情:

 <?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");
 }
 ?>

作为一个注释,gameSubmit.php页面也有相同的消息,如果... elseif ...则为player3Answer&amp; player4Answer。

所以我的问题是......

如果用户登录并打开index.php页面,则会提示他/她使用“echo $ row [”Question“]”(这是使用$ 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的相应文本输入中输入答案。一旦用户点击提交按钮,表单重定向到gameSubmit.php - 一旦加载,if(isset) ($ _POST ['submitted'])){启动并交叉检查每个用户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以获得正确的答案 - 因此,纯粹的运气在“评分”答案时会出现相同的答案。

为了在表单操作页面上实现输入验证,我需要做什么/需要纠正什么?

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和正确的答案 - 我也希望我的代码能够找到正确的答案而不是我必须输出每个答案,这样一来,如果添加一条记录,我就不必更新代码了。

感谢您的时间和帮助,非常感谢! (这是决赛周,我不能再强调了)

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

在索引页面中添加隐藏元素,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
