伙计们，这是我的主页

<?php
$random = rand(4, 5);
$random2 = rand(1, 12);
$random3 = rand(1, 60);
$random4 = rand(1, 60);
$random5 = rand(1, 60);
if ($random2 % 4 != 0) {
$random2 += 4 - ($random2 % 4);
$call = $random;
} else {
$random2 += 4 - ($random2 % 4);
$call = $random2;
}
$answer = $random * $random2;
?>

这是我的DO页面，用于在用户单击他/她在每个问题上选择的所有单选按钮后检查EasyGame页面，它将带到Dopage以验证他/她提交的答案是否正确。 

<?php
$random = isset($_POST['random']) ? intval($_POST['random']) : 0;
$random2 = isset($_POST['random2']) ? intval($_POST['random2']) : 0;
$random3 = isset($_POST['random3'])? intval($_POST['random3']) : 0;
$random4 = isset($_POST['random4'])? intval($_POST['random4']) : 0;
$random5 = isset($_POST['random5'])? intval($_POST['random5']) : 0;
$answer = isset($_POST['answer'])? intval($_POST['answer']) : 0;
$mcq = $_POST['mcq'];
?>

为什么当我单击第一页的单选按钮并提交时，下一页上的值为 0，而我验证的答案是错误的？

我查看了您的代码，发现您没有在第一页存储选项，当您尝试将其发布到下一页时，它将变为零，因为所有单选按钮都具有相同的名称，当您将其发布到下一页时，它只会发布选定的无线电值。

为了满足您的要求，您只需要在下面使用我的代码作为第一页：

<?php
$random = rand(4, 5);
$random2 = rand(1, 12);
$random3 = rand(1, 60);
$random4 = rand(1, 60);
$random5 = rand(1, 60);
if ($random2 % 4 != 0) {
$random2 += 4 - ($random2 % 4);
$call = $random;
} else {
$random2 += 4 - ($random2 % 4);
$call = $random2;
}
$answer = $random * $random2;
?>

    <h1> Easy Game 2 </h1>
    <h2> Multiple Choice! </h2>
    <div class="border_solid">
        <div id="timer"></div>
    </div>

</head>
<body>
<form method="post" action="doeasygame2.php">
<table cellspacing="40" class="table">
        <tr>
            <td>
                <label for="question_1"><?php echo $random; ?> X <?php echo $random2; ?> =?</label>

                <input type="radio" id="mcq" name="mcq" value="<?php echo $answer; ?>"><?php echo $answer; ?>
            </td>
            <td>

    <input type="hidden" name="random" value="<?php print $random ?>">

var d = 0;
function myTimer() {

请在第二页使用以下代码：

<?php
$random = isset($_POST['random']) ? intval($_POST['random']) : 0;
$random2 = isset($_POST['random2']) ? intval($_POST['random2']) : 0;
$random3 = isset($_POST['random3'])? intval($_POST['random3']) : 0;
$random4 = isset($_POST['random4'])? intval($_POST['random4']) : 0;
$random5 = isset($_POST['random5'])? intval($_POST['random5']) : 0;
$answer = isset($_POST['answer'])? intval($_POST['answer']) : 0;
$mcq = $_POST['mcq'];
?>
