【问题描述】：
如果有人可以告诉我，我需要这方面的帮助，那将非常棒且很有帮助。
我试图通过复选框显示多个值，PHP 中的此信息已发送到电子邮件。应用时，我可以让所选列表中的任何人单独工作
这是我的 PHP 和 HTML 代码，一切正常，只是程序只会发送所选列表中的一个，即使我选择了多个。
$ch1、$ch2、$ch3、$ch4、$ch5
PHP
<?php
if(isset($_POST['email'])) {
$email_to = "";
$email_subject = "";
function died($error) {
// Error Code
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['firstname']) ||

一个常见的技巧是将您的复选框命名为
checkboxes[]，尽管这显然不是首选，真正的答案是给它们不同的名称。
