简单的PHP联系人表单返回500内部服务器错误 - simple PHP contact form returns 500 internal server error

simple PHP contact form returns 500 internal server error

我试图实现一个简单的形式，为游客联系我通过。我使用php(我是一个非常初学者)，我有问题，它是返回500内部服务器错误。表单显示良好的一切，只是当我按下提交，它发生了。表单在本页

代码如下:

<?php 
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
  {
  //send email
  $email = $_REQUEST['email'] ;
  $subject = $_REQUEST['subject'] ;
  $message = $_REQUEST['message'] ;
  mail('tburn76@gmail.com', $subject,
  $message, 'From:' . $email);
  echo "Thank you for using our mail form";
  }
else
//if "email" is not filled out, display the form
  {
  echo "<form method='post' action='mailform.php'>
  Email : <input name='email' type='text'><br>
  Subject: <input name='subject' type='text'><br>
  Message:<br>
  <textarea name='message' rows='15' cols='40'>
  </textarea><br>
  <input type='submit'  value='Send'>
  </form>";
  }
?>

很多谢谢,汤米

这是您的主机提供商的问题。500是服务器错误没有一个程序但是你应该在
之前做这个

将第二回显更改为

  echo "<form method='post' action='".$_SERVER['PHP_SELF']."' name='email'>
  Email : <input name='email' type='text'><br>
  Subject: <input name='subject' type='text'><br>
  Message:<br>
  <textarea name='message' rows='15' cols='40'>
  </textarea><br>
  <input type='submit' name='email' value='Send'>
  </form>";

代码将是

<?php 
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
  {
  //send email
  $email = $_REQUEST['email'] ;
  $subject = $_REQUEST['subject'] ;
  $message = $_REQUEST['message'] ;
  mail('tburn76@gmail.com', $subject,
  $message, 'From:' . $email);
  echo "Thank you for using our mail form";
  }
else
//if "email" is not filled out, display the form
  {
  echo "<form method='post' action='".$_SERVER['PHP_SELF']."' name='email'>
  Email : <input name='email' type='text'><br>
  Subject: <input name='subject' type='text'><br>
  Message:<br>
  <textarea name='message' rows='15' cols='40'>
  </textarea><br>
  <input type='submit' name='email' value='Send'>
  </form>";
  }
?>

PS:我认为这不是一个代码错误，但这将帮助你
好运！
