当我有这个时，我的PHP脚本不会发送回复：
$headers = "From: " . $clientEmail . "<" . $clientEmail . ">" . "\r\n" . "Reply-To: " . $clientEmail;
但是当我改变它时，它正在工作：
return mail($clientEmail, $subject . " (copy contact form xxx)", $message, $headers);
我有回复邮件，但echo无效：
echo 'Message has been sent (OK)';
当我点击正确发送时，我希望看到发送消息，就像消息现在显示丢失的用户名一样。
我不想将我转到新的回复消息页面，而是希望留在表单提交页面上并对正确的帖子发表评论。
我需要在.js和.php中更改哪些内容？
HTML：
<form action="assets/contact.php" class="contact-form long_contact" method="POST">
<div class="form-group">
<input type="text" name="username" id="username" class="username form-control" placeholder="Your Username" value="">
<i class="fa fa-user"></i>
<span class="cross">x</span>
<span class="verify"><i class="fa fa-check" aria-hidden="true"></i></span>
<div class="alert alert-danger custom-alert">

答案 0 :(得分：0)
问题在于，您希望显示文本的echo代码位于HTML的错误位置。它可以位于隐藏标记中，也可以位于script内，也可以位于HTML注释中。确保它显示在正确的位置。
