Question

我是PHP的新手，我正在努力使电子邮件提交（简报）表单工作。我有以下HTML表单：

<form class="form-inline" action="mail-handler.php" method="post">
      <div class="col-sm-5 col-sm-offset-2 col-md-4 col-md-offset-3">                       
            <label class="sr-only" for="email">Email</label>
                <input type="text" id="email" placeholder="Your email address.." />
      </div>
      <div class="col-sm-3 col-md-2">
                 <input type="submit" name="submit" class="btn btn-submit" value="Submit">
      </div>
</form>

为此，我创建了一个mail-handler.php文件，其中包含以下代码：

<?php 
$to = "horia.imperial@gmail.com"; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$subject = "Form submission";
$subject2 = "You have just subscribed to the Plantsnap newsletter!";
$message =  $from . " just subscribed for your Newsletter" ;
$message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];

//Headers
$headers .= "From: <".$from. ">"; 
$headers2 = "From:" . $to;
if(isset($_POST['submit'])){    
mail($to,$subject,$message,$headers);
mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
echo "You have subscribed to our newsletter. Thank you, we will contact you shortly.";
// You can also use header('Location: thank_you.php'); to redirect to another page.
// You cannot use header and echo together. It's one or the other.
} ?>

问题：当我按下提交按钮时，它会向我的地址发送一封电子邮件，但我收到以下电子邮件：

自：发送至：horia.imperial@gmail.com 日期：2017年3月16日星期四下午12:23 主题：表格提交加密：标准（TLS）了解更多

正如您所看到的，from：字段为空，这意味着$ from = $ _ POST ['email']返回NULL，无论我在输入字段中输入什么。

我做错了什么？

另外，我还有一个问题：

如何将表单提交中的消息显示为表单下的一个小工具提示，而不是将我重定向到link / mail-handler.php并回显“您已订阅我们的新闻通讯。谢谢，我们会联系你很快。“

提前致谢！

Answer 1

输入字段需要name属性才能与表单一起发送

<input type="text" name="email" id="email" placeholder="Your email address.." />

Answer 2

您没有设置name属性。试试这个：

<input type="text" name="email" placeholder="Your email address.." />

只是一个小建议：如果您只为自己发送电子邮件地址，某些地址可能会丢失。将电子邮件插入emails数据库表，如下所示：

$email = $_POST['email'];
mysqli_query($conn, "INSERT INTO emails (email, time) VALUES ($email, CURRENT TIME())");
