我正在创建一个类似于 http://www.sqlquiz.com/ 的测验系统我的结果页面有问题。 我已经创建了 4 个页面
index.php ---->welcomePage 我在查询字符串中使用变量 n
index.php
<p><a href="quizmain.php?n=1">Start SQL Quiz</a></p>
2.quizmain.php------------>此页面显示问题及其选项以及之后的内容 获取每个问题的响应后，它将转到 process.php 页面，在该页面中计算分数，并且每次计数器都会增加 1，以便在达到第 10 个问题后将显示最终结果页面
quizmain.php
<?php
session_start();
require_once("connection.php");
extract($_REQUEST);
$number = (int) $_GET['n']; //starting value 1
echo $number;
$n1=rand(1,100);
$_SESSION['RQuestionNumber']=$n1;
$q=mysql_query("select * from quiz WHERE qno = '".$n1."'");
$a=mysql_fetch_array($q);
echo $a['qno'];
echo $a['ans'];
?>
<body>
<table>
<tr>
<td width="757" height="390"><div align="center">
<form method="post" action="process1.php">
<input type="radio" name="question" value="a" />
<?php echo $a[2]?></label>
</p>
<p><br />
<label>
<input type="radio" name="question" value="b" />
<?php echo $a[3]?></label>
</p>
<p><br />

<input type="radio" name="question" value="c" />
<?php echo $a[4]?></label>
</p>
<p><br />
<label> </label>
<label>
<input type="radio" name="question" value="d" />
<?php echo $a[5]?></label>
</p>
<p> </p>
<p>
<label>
<input type="submit" value="Submit" name="Submit" />
<input type="hidden" name="number" value="<?php echo $number; ?>" />
</form>
</label>
<br />
<br />
<br />
</p></td>
</tr>
</table>
</body>
</html>
process.php
<?php
session_start();
require_once('connection.php');
extract($_REQUEST);
//Check to see if score is set_error_handler
if(!isset($_SESSION['score'])){
$_SESSION['score'] = 0;
}
if($_POST)
{
$number = $_REQUEST['number']; //value of number is 1 initially
$selected_choice = $_REQUEST['question'];
$next = $number+1; //
$total=10;
$_SESSION['RQuestionNumber'];
$q = mysql_query("SELECT ans FROM quiz WHERE qno = '".$_SESSION['RQuestionNumber']."'");
$result=mysql_fetch_array($q);
//$store=array();
//Compare
if($result[0][0] == $selected_choice){
//Answer is correct
$_SESSION['score']++;
}
//Check if last question
if($number == $total){
header("location: resultTable.php");
exit();
} else {
header("location: quizmain.php?n=".$next); //now the value of n is 2
}
}
?>
结果表.php
现在在此页面中，我想打印测验期间出现的所有问题(同一组问题)以及标记的答案和正确的答案 我尝试过使用 session 变量，但它不起作用。
<?php session_start(); ?>
<p>Final Score: <?php echo $_SESSION['score']; ?></p>
<?php session_destroy(); ?>
最佳答案
您的 session 值每次都会被覆盖，因此最后您将获得最后一个问题 ID。如果您想要所有问题 ID，请使用数组。试试这个:
quizmain.php
<?php
session_start();
require_once("connection.php");
extract($_REQUEST);
$number = (int) $_GET['n']; //starting value 1
echo $number;
$n1=rand(1,100);
$_SESSION['RQuestionNumber'][]=$n1;
$q=mysql_query("select * from quiz WHERE qno = '".$n1."'");
$a=mysql_fetch_array($q);
echo $a['qno'];
echo $a['ans'];
?>
<body>
<table>
<tr>
<td width="757" height="390"><div align="center">
<form method="post" action="process1.php">
<input type="radio" name="question" value="a" />
<?php echo $a[2]?></label>
</p>
<p><br />
<label>
<input type="radio" name="question" value="b" />
<?php echo $a[3]?></label>
</p>
<p><br />
<label>
<input type="radio" name="question" value="c" />
<?php echo $a[4]?></label>
</p>
<p><br />
<label> </label>
<label>
<input type="radio" name="question" value="d" />
<?php echo $a[5]?></label>
</p>
<p> </p>
<p>
<label>
<input type="submit" value="Submit" name="Submit" />
<input type="hidden" name="number" value="<?php echo $number; ?>" />
</form>
</label>
<br />
<br />
<br />
</p></td>
</tr>

process.php
<?php
session_start();
require_once('connection.php');

$_SESSION['score'] = 0;
}
if($_POST)
{
$number = $_REQUEST['number']; //value of number is 1 initially
$selected_choice = $_REQUEST['question'];
$next = $number+1; //
$total=10;
$last_que = $_SESSION['RQuestionNumber'][count($_SESSION['RQuestionNumber'])-1];
// $_SESSION['RQuestionNumber'];
$q = mysql_query("SELECT ans FROM quiz WHERE qno = '".$last_que."'");
$result=mysql_fetch_array($q);

<?php
