此代码提交表单，下面的代码是表单 有这么多代码的原因是为了使 php 安全。 我认为代码中不应该有任何错误，但这可能是问题所在

    <form id="contactform" action="processForm.php" method="post">
    <table>
      <tr>
        <td><label for="name">Name:</label></td>
        <td><input type="text" id="name" name="name" /></td>
      </tr>
      <tr>
        <td><label for="email">Email:</label></td>
        <td><input type="text" id="email" name="email" /></td>
      </tr>
      <tr>

        <td><textarea id="message" name="message" rows="5" cols="20"></textarea></td>
