Question

请你帮我。我创建了一个Facebook应用程序发布到墙上并向mysql数据库添加详细信息但是目前用户必须对应用程序进行身份验证，并且这样做会将空白数据发送到数据库。如何在发布权限时更新数据库。

<?php
include_once("src/facebook.php"); //include facebook SDK

$config = array(
     'appId' => 'xxxx',
    'secret' => 'xxxx',
    'allowSignedRequest' => false // optional but should be set to false for non-canvas apps
  );


  $facebook = new Facebook($config);
  $user_id = $facebook->getUser();



  $formemail = $_POST['formemail'];
  $formname = $_POST['formname'];
  $formphone = $_POST['formphone'];

  echo $email;
  echo $formname;
  echo $formemail;
  echo $formphone;

?>

  <head>

    <link rel="stylesheet" type="text/css" media="all" href="css/style.css">

  <body>




  <script type="text/javascript">
    opener.location.reload();
    window.close();
</script>



  <?php
    if($user_id) {

      // We have a user ID, so probably a logged in user.
      // If not, we'll get an exception, which we handle below.
      try {
        $ret_obj = $facebook->api('/me/feed', 'POST',
                                    array(
                                      'link' => 'https://apps.facebook.com/ahora-opening-comp',
                                      'message' => 'I have just entered the competition to WIN a table for 8 at Ahora on the 28th September at O2 Accademy, Sheffield '
                                 ));


        // Give the user a logout link

根据Facebook文档，返回值是帖子的ID，如果成功，则为字符串值。

如果publish_stream成功，只想添加到mysql数据库
