我正在尝试从联系人页面发送电子邮件。该功能工作正常，我能够从html页面发送邮件，但我面临的唯一问题是我无法看到状态div(成功或失败)。
最初页面被重定向到php文件，没有任何状态消息。我在php中使用header()添加了页面重定向到实际的mailsend.html。现在我想在发送操作之后显示邮件是否已发送的状态。
下面是代码片段。请帮助。提前谢谢。
mailSend.html代码:
<?php if(!empty($statusMsg)){ ?>
<p class="statusMsg <?php echo !empty($msgClass)?$msgClass:''; ?>"><?php echo $statusMsg; ?></p>
<?php } ?>
<form action="example.php" method="post" enctype="multipart/form-data">
<div class="form-group">
<input style = "padding-left:2%; width: 97%;" type="text" name="name" class="form-control" value="" placeholder="Name" required="">
</div>
<div class="form-group">
<input style = "padding-left:2%; width: 97%;" type="email" name="email" class="form-control" value="" placeholder="Email address" required="">
</div>
<div class="form-group">
<input style = "padding-left:2%; width: 97%;" type="text" name="subject" class="form-control" value="" placeholder="Subject" required="">
</div>
<div class="form-group">
<textarea name="message" class="form-control" placeholder="Write your message here" required="" style = 'border :0.5px solid '></textarea>
</div>
<div class="form-group">
<input type="file" name="attachment" class="form-control" style = 'border :0.5px solid; height: auto;'>
</div>
<div class="submit">
<input type="submit" name="submit" class="btn" value="SUBMIT" style= 'float : right;'>
</div>
</form>

<?php
//first we leave this input field blank
$recipient = "";
//if user click the send button
if(isset($_POST['submit'])){

$recipient = $_POST['email'];

$message = $_POST['message'];
$sender = "From: xyz@gmail.com";

您正在发送到一个.html页面，该页面默认情况下不处理PHP代码，服务器只提供它，除非在服务器上特别配置。将页面从mailSend.html重命名为mailSend.php，它应该会解析它。请确保将代码更改为发送到.php页面。

您需要传递消息本身，或者让脚本知道要显示哪条消息。最简单的方法是通过$_GET传递它，通过将它附加到您试图重定向的URL的末尾。像这样:
$target_url = mailSend.php;
$get_data = '?statusMsg=' . urlencode($statusMsg) . '&$msgClass=' . urlencode($msgClass);
header( 'Location: ' . $target_url . $get_data );
$_GET变量在mailSend.php上恢复。如:
$statusMsg = urldecode($_GET['statusMsg']);
$msgClass= urldecode($_GET['msgClass']);
还有其他方法可以将数据从一页获取到另一页，但我将把它留给你做研究。因为这超出了简单回答的范围。
