Question

我有一份包含5个问题的问卷表，每个问题有5个单选按钮选项。现在，我想按下提交按钮捕获此表单数据。我在使用POST方法发送的这些单选按钮的值填充数组时遇到困难。

我写的代码是抛出错误：“注意：第11行的E：\ xampp \ htdocs \ dataCollect \ form1.php中的未定义索引：'radio11'

代码如下：

<?php
if (isset($_POST['btnForm1'])){
for($count = 1; $count < 6; $count++){
$radioName = "radio1".$count;
$arrForm1 = array($_POST["'".$radioName."'"]);
}}
<?>

Answer 1

这是不正确的：

$arrForm1 = array($_POST["'".$radioName."'"]);
                         ^^^^----------^^^^----useless

"'"引号绝对是不必要的。这就是你应该拥有的一切：

$arrForm1 = array($_POST[$radioName]);

为什么将单选按钮的值包含在数组中。你只会从每个单选按钮集中取回一个值。
