Question

我试图在php中创建一个粘性表单，包括文本框，文本区域，单选按钮组，复选框组和下拉列表。我设法让粘性部分与文本框一起工作，但对于其他一切，它要么不在重新加载，要么在特定元素之后不显示内容。例如，我的代码如下，Male单选按钮后没有显示任何内容。只是文字＆＃34;男＆＃34;，但之后什么都没有。我不确定我做错了什么，我不知道如何使剩余的元素变得粘稠（文本区域，复选框和单选按钮）。

<?php
function display_form()
{
   $self = $_SERVER['PHP_SELF'];
   global $nameErr,$emailErr,$subjectErr,$commentErr,$termErr;
   $name = isset($_POST['name']) ? $_POST['name'] : '';
   $email = isset($_POST['email']) ? $_POST['email'] : '';  
   $subject = isset($_POST['subject']) ? $_POST['subject'] : '';
   $comment = isset($_POST['comment']) ? $_POST['comment'] : '';
?>
