如何在使用 PHP 邮件程序成功发送电子邮件后打印 html 中的消息？

Question

我正在使用 PHP 邮件发送我的 html 联系表，使用 action="mail.php"。好吧，我从 youtube 教程中获取了代码，我唯一的问题是这行代码 <?php print r($message);?> 为了使这行代码工作，索引文件必须 be.php 所以我必须使用 form method="post" enctype="multipart/form-data" 而不是 action="mail.php" 我测试了它，它工作得很好；按下发送按钮后，我在联系表的顶部收到了一条打印消息。但是，如果我将 PHP 配置和 link 分开到我的 html 联系表格中，该表格仍会执行并且我会收到电子邮件，但打印消息不会出现，因为它是 html。请找到以下代码。

          <form method="post" action="mail.php" role="form">
                 <div class="row">
                    <div class="col-md-6">

                          <input type="text" name="name" placeholder="Full Name" class="form- 
             control" required />

将消息放入会话中，提交表单后重定向到当前页面并显示保存在会话中的消息，然后清除该会话消息（即闪消息）。
