How to Process Form Request

所以我在WordPress页面中构建了一个表单，如下所示：

<form action="/help" method="GET">
                        <h2 class="heading post-title">Contact Us</h2>
                        <label>Name:</label><br>
                        <input type="text" name="name" /><br>
                        <label>Email:</label><br>
                        <input type="text" name="email" /><br>
                        <label>Subject:</label><br>
                        <input type="text" name="subject" /><br>
                        <label>Message:</label><br>
                        <textarea name="msg" style="width:200px;height:380px"></textarea><br><br>
                        <input type="submit" style="width:206px;margin:0 auto;border:1px solid gray;border-radius:3px;background-color:orange;color:white" />
                        <br>
                        <label style="color:red"><?php if(isset($_GET[\'success\'])) echo "Your message has successfully been sent!"; else echo "<br>"; ?></label>
                      </form>

和/帮助重定向到包含此代码的同一页面，因此我尝试将该页面重定向到自身
包含上述表单（page help.php）的同一页面，在开始时也包含一些用于处理数据的php，如下所示：

<?php 
if(isset($_POST[\'message\']))
{
 // require \'PHPMailerAutoload.php\';

  $mail = new PHPMailer;

  $mail->isSMTP();                                      // Set mailer to use SMTP
  $mail->Host = \'mail.arkzel.com\';  // Specify main and backup server
  $mail->SMTPAuth = true;                               // Enable SMTP authentication
  $mail->Username = \'[email protected]\';                            // SMTP username
  $mail->Password = \'Xwbs*YR!\';                           // SMTP password
  $mail->SMTPSecure = \'tls\';                            // Enable encryption, \'ssl\' also accepted

  $mail->From = $_POST[\'email\'];;
  $mail->FromName = $_POST[\'name\'];;
  $mail->addAddress(\'[email protected]\');               // Name is optional

  $mail->WordWrap = 50;                                 // Set word wrap to 50 characters
  $mail->isHTML(true);                                  // Set email format to HTML

  $mail->Subject = $_POST[\'subject\'];;
  $mail->Body    = $_POST[\'message\'];
  $mail->AltBody = \'This is the body in plain text for non-HTML mail clients\';

  if(!$mail->send()) {
     echo \'Message could not be sent.\';
     echo \'Mailer Error: \' . $mail->ErrorInfo;
     exit;
  }
  header("location: help?success=1");
}
?>

但是，我得到的是一条404：找不到的消息<非常困惑。

Hide gravity forms

我在我的网站上设置了重力表单，我想根据用户是否已在表单/数据库中发布条目来隐藏/显示表单。如果他们做了一个条目，那么我想隐藏它并显示一些简单的文本。我知道重力形式允许你限制参赛人数，但这并不是我想要的。我猜我必须查询数据库，但我不确定最好的编写方法。我是否需要使用诸如get\\u posts之类的工具来检查作者是否有条目？这是最好的方式吗？
