我有一个订阅表，只有两个文本框的名称和电子邮件。我希望这些信息存储在mysql数据库中。提交表单时，我可以连接到数据库，但信息不会发送。这是表单的代码（只是感兴趣的部分）：

<div class="jumbotron text-center">
  <h1>Community Garden</h1>
  <p>We are a local community that
  grows organic vegetables and fruit</p>
  <img src="Front.jpg" class="img-rounded" alt="front" > <br><br>
  <form class="form-inline" action="news.php" method="post'>
    <div class="input-group">
      <input type="text" name="name" class="form-control" size="50" placeholder="Name" required> 
      <input type="text" name="email" class="form-control" size="50" placeholder="Email Address" required>
     <br><br> <div class="input-group-btn">
        <button type="submit" name="submit" value="submit" class="btn btn-danger">Subscribe</button>
      </div>
    </div>
  </form>
</div>

这是用于数据库连接和信息存储的php脚本。这个文件名为news.php。非常感谢您的帮助。
