本文旨在解决在使用PHP发送邮件后，状态信息（成功或失败）无法在HTML页面上显示的问题。通过修改文件后缀名、使用$_GET传递状态信息，并进行URL编码和解码，可以有效地在mailSend.php页面上显示邮件发送状态。
原始代码存在的问题在于，邮件发送状态信息在 example.php 中生成，但 mailSend.html 页面无法直接访问这些信息，因为 HTML 页面不会执行 PHP 代码。使用 header('Location: mailSend.html') 只是简单地重定向页面，而没有传递任何状态信息。
要解决这个问题，需要以下几个步骤：
将 mailSend.html 重命名为 mailSend.php： 这是因为只有 .php 文件才能被服务器解析并执行 PHP 代码。

使用 $_GET 传递状态信息： 在 example.php 中，将状态信息（$statusMsg 和 $msgClass）附加到 URL 上，然后进行重定向。
在 mailSend.php 中获取状态信息： 使用 $_GET 变量获取传递过来的状态信息，并在页面上显示。
将 header('Location: mailSend.html') 替换为以下代码：
$target_url = 'mailSend.php';
$get_data = '?statusMsg=' . urlencode($statusMsg) . '&msgClass=' . urlencode($msgClass);
header('Location: ' . $target_url . $get_data);
exit(); // 确保在重定向后停止执行脚本代码解释：
在 mailSend.php 文件的顶部，添加以下代码：
<?php
if (isset($_GET['statusMsg']) && isset($_GET['msgClass'])) {
$statusMsg = urldecode($_GET['statusMsg']);
$msgClass = urldecode($_GET['msgClass']);
} else {
$statusMsg = '';
$msgClass = '';
}
?>代码解释：
确保以下代码存在于 mailSend.php 文件中，用于显示状态信息：
<?php if(!empty($statusMsg)){ ?>
<p class="statusMsg <?php echo !empty($msgClass)?$msgClass:''; ?>"><?php echo $statusMsg; ?></p>
<?php } ?>代码解释：
以下是修改后的 example.php 示例：
<?php
//first we leave this input field blank
$recipient = "";
//if user click the send button
if(isset($_POST['submit'])){
//access user entered data
$recipient = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$sender = "From: <a href="https://www.php.cn/link/89fee0513b6668e555959f5dc23238e9" rel="nofollow" target="_blank" >[email protected]</a>";
//if user leave empty field among one of them
if(empty($recipient) || empty($subject) || empty($message)){
$statusMsg = "All inputs are required!";
$msgClass = 'errordiv';

通过将 mailSend.html 重命名为 mailSend.php，并使用 $_GET 传递状态信息，可以有效地解决 PHP 邮件发送后状态信息无法显示的问题。这种方法简单易懂，适用于大多数情况。在实际应用中，可以根据具体需求选择更合适的解决方案。
