我正在尝试创建一个多项选择测验。问题和选择在应用程序中显示得非常好。
在测验结束时，我可以计算出有多少答案是正确的，错误的和未成功的答案，但我无法显示所选答案并将其标记为正确，不正确或未答复。
我一直在尝试编写应用程序的这一部分差不多一个月，我似乎无法弄明白。
如何在多项选择测验结束时显示所选答案并将其标记为正确，不正确或未答复？
这是questions.php代码，下面是result.php代码。
<?php
session_start();
?>
<?php
require 'config.php';
$category='';
if(!empty($_POST['name'])){
$name=$_POST['name'];
$category=$_POST['category'];
mysql_query("INSERT INTO users (id, user_name,score,category_id)VALUES ('0','$name',0,'$category')") or die(mysql_error());
$_SESSION['name']= $name;
$_SESSION['id'] = mysql_insert_id();
}
$category=$_POST['category'];
if(!empty($_SESSION['name'])){
?>
