Facebook：php上传照片和张贴在墙上

Question

新的PHP请原谅我愚蠢的问题。

我正在创建我的第一个fb应用程序。它允许用户浏览他们的本地驱动器并选择一张照片。一旦提交，它将重定向到下一页并处理到存储到我的服务器上，然后张贴到用户的墙上。

这个应用程序并没有太多的工作。用户浏览和将照片存储到我的服务器上的部分正在工作，但无法从我的服务器中取回照片并将其张贴到用户的墙上。

的config.php：

<?php 
require_once 'facebook.php'; 

$app_id = ""; 
$app_key = ""; 
$app_secret = ""; 
$canvas_url = ""; 

$facebook = new Facebook(array(
'appId' => $app_id, 
'secret' => $app_secret, 
'cookie' => true 
)); 

$session = $facebook->getSession(); 

if (!$session) { 

     $url = $facebook->getLoginUrl(array(
     'canvas' => 1, 
     'fbconnect' => 0, 
     'req_perms' => 'publish_stream, user_photos, read_stream, read_friendlists' 
     )); 

     echo "<script type='text/javascript'>top.location.href = '$url';</script>"; 

    }//end if session user 
else 
{ 

     try { 

     $uid = $facebook->getUser(); 
     $me = $facebook->api('/me'); 

     $updated = date("l, F j, Y", strtotime($me['updated_time'])); 

     echo "Hello " . $me['name'] . "<br />"; 
     echo "You last updated your profile on " . $updated . "<br />" ; 
     echo "<img src='https://graph.facebook.com/".$uid."/picture'/>"; 
     }//end try getUser 
     catch (FacebookApiException $e) { 

     echo "Error:" . print_r($e, true); 

     }//end catch getUser 
}//end else user 

index.php文件包含表单：

<form enctype="multipart/form-data" action="uploader.php" method="POST"> 
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" /> 
Choose a file to upload: <input name="uploadedfile" type="file" /><br /> 
<input type="submit" value="Upload File" /> 
</form> 

uploader.php运行过程

$target_path = "uploads/"; 
     $target_path = $target_path . basename($_FILES['uploadedfile']['name']); 

     if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { 
      echo "The file ". basename($_FILES['uploadedfile']['name']). 
      " has been uploaded" . "<br />"; 
     } else{ 
      echo "There was an error uploading the file, please try again!" . "<br />"; 
     } 
     try { 
    $post_id = $facebook->api("/".$uid."/feed", "post", array("picture"=>$target_path)); 
    if(isset($post_id)) 
     echo "A new post to your wall has been posted with id: $post_id"; 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    } 

我一直在尝试许多不同的方法，其我可以在网上找到，但它不起作用。我曾尝试添加$ facebook-> setFileUploadSupport（true）;但收到错误。

请指教我如何才能将照片上传到用户墙上。 非常感谢您

我认为这应该工作：

$target_folder = "uploads/"; 
$target_path = $target_folder . basename($_FILES['uploadedfile']['name']); 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { 
    echo "The file ". basename($_FILES['uploadedfile']['name']). 
    " has been uploaded" . "<br />"; 

    $file_path = $target_folder . $_FILES['uploadedfile']['name']; 
    $arr = array(); 
    $arr["image"] = '@' . realpath($file_path); 
    try { 
     $post_id = $facebook->api("/".$uid."/feed", "post", $arr); 
     if(isset($post_id)) 
     echo "A new post to your wall has been posted with id: $post_id"; 
    } catch (FacebookApiException $e) { 
     error_log($e); 
    } 
} else{ 
    echo "There was an error uploading the file, please try again!" . "<br />"; 
}

你好老兄此代码对我的作品完全一样。你的代码是什么，它会将帖子发布到你的相册或应用程序相册中。

 
if(isset($_POST['upload'])) 
{ 
    if (isset($_FILES["file"]) && $_FILES["file"]["error"]==0) 
    { 
     $file='images/'.$_FILES["file"]['name']; 
     if(move_uploaded_file($_FILES["file"]["tmp_name"],$file)) 
     { 
      $facebook->setFileUploadSupport(true); 
      $post_data = array(
      'name'=>$_POST['album'], 
      'description'=>$_POST['album'] 
      ); 
      $data['album'] = $facebook->api("/me/albums", 'post', $post_data); 
      //$file = $file_name; 
      $post_data = array(
      "message" => $_POST['message'], 
      "source" => '@' . realpath($file) 
      ); 
      $album_id = $data['album']['id']; 
      $data['photo'] = $facebook->api("/$album_id/photos", 'post', $post_data); 
     } 
    } 
    /**/ 

} 

当您从应用程序上传任何图片时，facebook会在您的应用程序配置文件中创建一个相册。但是这段代码会将照片发布到你的相册中。

$_POST['album']

是我在文本框中输入的专辑名称。然后，我只需发布表单并上传照片。我希望这会帮助你

Answer 3

$session = $facebook->getSession(); 
use getUser(); 

Answer 4

更换getSession()与getUser() 因为旧的PHP版本不识别getSession()功能。

使用此代码和它的工作对你罚款如Facebook文档这里How-To: Use the Graph API to Upload Photos to a user’s profile说

     // Create a new album

     $postdata = http_build_query(
