为自然语言形式开发配套php的问题 - Issues developing companion php for natural language form

请原谅，我是新手，我尝试过的不同的php并没有真正起作用。我已经找到了自然语言形式的例子，但没有一个与工作的PHP和我熟悉的PHP，当使用传统的形式，但我有问题把两者放在一起。

一般的表单布局如下:
我的名字是[你的名字]。
今天，我要[你要做什么?]。
我这么做是因为[拜托，为什么?]。
我[你说过你会做的]很重要，因为[大局]。
给我发封邮件，把我的新宣言发到[你的邮箱]
按钮1(发送电子邮件)
按钮2(复制所有文本和输入字段到剪贴板-现在不那么重要)

按钮1，我想用硬编码的电子邮件地址发送一份给我自己，也用他们输入的电子邮件地址发送一份给用户。

现在有点乱，因为我只是想让它工作…同样，我没有包含PHP，因为在这一点上——我已经把自己弄糊涂了，我不知道该包含什么。

<form method="post" action="todayiam.php">
  <div class="naturallanguageform">
    <div class="nlfinner">
      <p class="line">
<span class="copy">My name is </span>
        <span class="inputcontainer"><input class="textinput" name="name" value="" placeholder="[your name]">.</span>
        <span class="copy">Today, I am </span>
        <span class="inputcontainer"><input class="textinput" name="todayiam" value="" placeholder="[whatchya gonna do?]">.</span> 
        <span class="copy">I'm doing this because </span>
        <span class="inputcontainer"><input class="textinput" name="why" value="" placeholder="[c'mon, why?]">.</span>
<span class="copy"> It's important that I </span>
        <span class="inputcontainer"><input class="textinput" name="whatusaid" value="" placeholder="[what you said you'd do]"></span>
        <span class="copy"> because </span>
        <span class="inputcontainer"><input class="textinput" name="because" value="" placeholder="[the big picture]">.</span>
      </p>    
<span class="copy">Shoot me an email with my awesome new declaration at</span>
        <span class="inputcontainer"><input class="textinput" name="email" value="" placeholder="[your email]"></span>
      <p class="line">
        <button class="button">Send to E-mail</button>
      </p>
 <p class="line">
        <button class="button">Copy to post in comments</button>
      </p>
    </div>
  </div>
</form>

任何帮助都将是非常感谢的。

更新:

<?php
       // from the form
       $name = trim(strip_tags($_POST['name']));
       $email = trim(strip_tags($_POST['email']));
       $message = htmlentities($_POST['todayiam']);
       // set here
       $subject = "Contact form submitted!";
       $to = 'email@gmail.com';
       $body = <<<HTML
$message
HTML;
       $headers = "From: $email'r'n";
       $headers .= "Content-type: text/html'r'n";
       // send the email
       mail($to, $subject, $body, $headers);
       // redirect afterwords, if needed
       header('Location: index.html');
?>

另一个更新

我已经改变$headers = "From: $email'r'n";to $headers = "From: email@gmail.com"。"' r ' n";设置一个静态地址(我的支持电子邮件)，电子邮件仍然被识别为来自CGI Mailer。我已经验证了这不是缓存问题，并且正在使用正确的文件。

<?php 
if (isset($_POST['name'], $_POST['todayiam'], $_POST['why'], $_POST['whatusaid'], $_POST['because'], $_POST['email']) {
    // We enter this statement only if all the fields has been properly defined, this to avoid getting undefined index
    $name = $_POST['name'];
    $todayIam = $_POST['todayiam'];
    $why = $_POST['why'];
    $whatYouSaid = $_POST['whatusaid'];
    $because = $_POST['because'];
    $email = $_POST['email'];
    // We define the variables for using in mail()
    $to  = 'email@gmail.com';
    $to .= ', '.$email; // You wanted them to recieve a copy
    $subject = "Contact form submitted!";
    // You can put a lot more headers, check out the mail() documentation
    $headers = "From: email@gmail.com" . "'r'n" ;
    $headers .= "Content-type: text/html'r'n";
    // Compose a $message from all the variables
    $message = "My name is $name. ";
    $message .= "Today, I am $todayIam.";
    $message .= "I'm doing this because $why.";
    $message .= "It's important that I $whatYouSaid";
    $message .= "because $because.";
    if (mail($to, $subject, $message, $header)) {
        // Mail was successfully sent! Do something here
    }
}
?>

在你发布你的答案之前，我正在写这个脚本:

<?php
 // from the form
       $name = trim(strip_tags($_POST['name']));
       $email = trim(strip_tags($_POST['email']));
       $message = htmlentities($_POST['todayiam']);

       // set here
       $subject = "Contact form submitted!";
       $to = 'email@gmail.com';
       $body = <<<HTML
$message
HTML;
       $headers = "From: $email'r'n";
       $headers .= "Content-type: text/html'r'n";
       // send the email
       mail($to, $subject, $body, $headers);
       // redirect afterwords, if needed
       header('Location: index.html');
?>

邮件=美元削减(strip_tags ($ _POST['邮件']));字段正在提取用户的电子邮件，并使用它作为$header中所述的发送来源…所以它工作得很好。有了新的脚本，你张贴，我不能让它与我的硬编码电子邮件或用户的电子邮件作为FROM工作。一开始，我真的很想了解剧本之间的区别，为什么一个能成功，而另一个不行，但现在……我真的只是希望我的电子邮件被硬编码为FROM。我以后再担心这些差异。就像我之前说过的，我确实尝试过以各种不同的形式来实现它。我相信这是一些简单的东西，我是一个PHP新手。谢谢。

对，所以经过一些评论的讨论，我决定发布一个答案，给出更多的细节，这样更容易读。

您的PHP代码缺少$message中所有字段的组合。这很容易做到，因为您可以在PHP中将变量放入字符串中。我来告诉你怎么做。我还将向您展示如何避免未定义索引。

<?php 
if (isset($_POST['name'], $_POST['todayiam'], $_POST['why'], $_POST['whatusaid'], $_POST['because'], $_POST['email']) {
    // We enter this statement only if all the fields has been properly defined, this to avoid getting undefined index
    $name = $_POST['name'];
    $todayIam = $_POST['todayiam'];
    $why = $_POST['why'];
    $whatYouSaid = $_POST['whatusaid'];
    $because = $_POST['because'];
    $email = $_POST['email'];
    // We define the variables for using in mail()
    $to  = 'email@gmail.com';
    $to .= ', '.$email; // You wanted them to recieve a copy
    $subject = "Contact form submitted!";
    // You can put a lot more headers, check out the mail() documentation
    $headers = "From: $email'r'n";
    $headers .= "Content-type: text/html'r'n";
    // Compose a $message from all the variables
    $message = "My name is $name. ";
    $message .= "Today, I am $todayIam.";
    $message .= "I'm doing this because $why.";
    $message .= "It's important that I $whatYouSaid";
    $message .= "because $because.";
    if (mail($to, $subject, $message, $header)) {
        // Mail was sucsessfullly sent! Do something here
    }
}
?>
