Facebook错误:；创建formpost数据失败”；将照片上传到粉丝页面 - Facebook Error: "failed creating formpost data" upload photo to fan page

我想上传一张照片到粉丝页面订阅源，但我不能，我读过一次才能发送，必须是POST FORM！是吗？

index.php

<html>
<head>
    <title>Index Page Facebook</title>
</head>
<body>
    <?php 
        require('config.php');

        if($user){
            $_SESSION['user_id'] = $user;
?>
        <form action="facebook3.php" method="post" accept-charset="utf-8">
            Message <input type="text" name="message"> <br>
            Photo: <input type="file" name="pictureFile">
                <input type="submit" value="Postar">
        </form>
<?php       
            exit();         
        }else{
    ?>
            <a href="<?php $facebook->getLoginUrl(array('scope' => $fbPermissions, 'redirect_uri' => $homeurl)); ?>">Login Facebook</a>;
    <?php       
        }
    ?>  
</body>
</html>

fb.php

<?php
include_once("config.php");
//destroy facebook session if user clicks reset

if($_POST)
{
    //$loginUrl = $facebook->getLoginUrl(array('scope' =>  'manage_pages'));    
    //$loginUrl = $facebook->getLoginUrl(array('scope' =>  'publish_stream'));  
    @include_once("config.php");

    //Post variables we received from user
    $userPhoto  = $_FILES["pictureFile"]["tmp_name"];
    $userMessage    = $_POST["message"];
    if(strlen($userMessage)<1)
    {
        //message is empty
        $userMessage = '';
    }
        //HTTP POST request to PAGE_ID/photos with the publish_stream
        $post_url = '/228433913910358/feed';
        //posts message on page statues
        $msg_body = array(
        'source'=>'@'.$userPhoto,
        'message' => $userMessage
        );
    if ($user) {
      try {
            $postResult = $facebook->api($post_url, 'post', $msg_body );
        } catch (FacebookApiException $e) {
        echo $e->getMessage();
      }
    }else{
     header("Location: index.php ");
    }
    //Show sucess message
    if($user && !empty($postResult))
     {
         echo '<html><head><title>Message Posted</title><link href="style.css" rel="stylesheet" type="text/css" /></head><body>';
         echo '<div id="fbpageform" class="pageform" align="center">';
         echo '<h1>Your message is posted on your facebook wall.</h1>';
         echo '<a class="button" href="'.$homeurl.'">Back to Main Page</a> <a target="_blank" class="button" href="http://www.facebook.com/'.$fbuser.'">Visit Your Page</a>';
         echo '</div>';
         echo '</body></html>';
     }
}
?>

所以，我尝试过邮寄，直接写路径$photo，但错误仍然存在！

创建formpost数据失败

我知道这是一个迟到的回复，但对于其他人来说，这可能会落在这里。。。

我看到了4件可能有问题的事情：
1.您需要确保$userPhoto包含图片的有效服务器路径
2.我用"图片"而不是"来源"来发布图片。（但可能两者都有效）3.由于您正在上传照片，因此它应该上传到//照片而不是//提要（或使用/photos上传到相册）
4.你需要确保你的$facebook-config的fileUpload设置为true，或者确保写下以下行：
$facebook->setFileUploadSupport（true）；在调用api之前。

以下是代码的样子（未经测试的代码）

<?php
include_once("config.php");
//destroy facebook session if user clicks reset
if($_POST)
{
    //$loginUrl = $facebook->getLoginUrl(array('scope' =>  'manage_pages'));    
    //$loginUrl = $facebook->getLoginUrl(array('scope' =>  'publish_stream'));  
    @include_once("config.php");
    $facebook->setFileUploadSupport(true);

//Post variables we received from user
$userPhoto  = $_FILES["pictureFile"]["tmp_name"];
$userMessage    = $_POST["message"];
if(strlen($userMessage)<1)
{
    //message is empty
    $userMessage = '';
}
    //HTTP POST request to PAGE_ID/photos with the publish_stream
    $post_url = '/228433913910358/photos';
    //posts message on page statues
    $msg_body = array(
    'image'=>'@'.$userPhoto,
    'message' => $userMessage
    );
if ($user) {
  try {
        $postResult = $facebook->api($post_url, 'post', $msg_body );
    } catch (FacebookApiException $e) {
    echo $e->getMessage();
  }
}else{
 header("Location: index.php ");
}
//Show sucess message
if($user && !empty($postResult))
 {
     echo '<html><head><title>Message Posted</title><link href="style.css" rel="stylesheet" type="text/css" /></head><body>';
     echo '<div id="fbpageform" class="pageform" align="center">';
     echo '<h1>Your message is posted on your facebook wall.</h1>';
     echo '<a class="button" href="'.$homeurl.'">Back to Main Page</a> <a target="_blank" class="button" href="http://www.facebook.com/'.$fbuser.'">Visit Your Page</a>';
     echo '</div>';
     echo '</body></html>';
 }
}
?>
