某些PHP字段不会显示在来自表单的电子邮件中

Question

我正在使用模板，并且主题随附的表单中的预制字段正在发送到我的电子邮件中，但是，我添加了其他字段，但这些字段未发布。电话，位置，联系时间和日期标签都会显示，但这些字段的输入数据不会随表格一起发送。

<?php
// Your Email
$recipient = "myemail@email.com"; // PLEASE SET YOUR EMAIL ADDRESS
$recaptcha_secret_key = 'yourAPIkey'; // PLEASE SET YOUR GOOGLE RECAPTCHA API KEY. If you are not using, please leave it blank.

if(!empty($recaptcha_secret_key) && array_key_exists('recaptcha',$_POST) ) {
    returnAndExitAjaxResponse(
        constructAjaxResponseArray(
            FALSE,
            'RECAPTCHA_FAILED_CHECK',
            array('error_message'=> 'RECAPTCHA_FAILED_CHECK')
