Facebook：php上傳照片和張貼在牆上

我正在創建我的第一個fb應用程序。它允許用戶瀏覽他們的本地驅動器並選擇一張照片。一旦提交，它將重定向到下一頁並處理到存儲到我的服務器上，然後張貼到用戶的牆上。

這個應用程序並沒有太多的工作。用戶瀏覽和將照片存儲到我的服務器上的部分正在工作，但無法從我的服務器中取回照片並將其張貼到用戶的牆上。

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文件包含表單：

<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運行過程

$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); 
    }

我一直在嘗試許多不同的方法，其我可以在網上找到，但它不起作用。我曾嘗試添加$ facebook-> setFileUploadSupport（true）;但收到錯誤。

請指教我如何才能將照片上傳到用戶牆上。非常感謝您

難道不是Facebook已經讓你這樣做？ – Benubird 2011-03-02 17:07:03

我想創建一個應用程序，他們將能夠通過它上傳照片。然後，照片將張貼到牆上，併發送到我的服務器。我會抓住這些照片，然後將它們顯示爲拼貼畫。 – meAtStackOverflow 2011-03-03 04:11:40

我認爲這應該工作：

$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 />"; 
}

感謝您的幫助，我試圖實現您的方法，但它仍然無法正常工作。 – meAtStackOverflow 2011-03-03 04:08:58

@meAtStackOverflow：歡迎您！介意分享您的工作方式，以便其他用戶從您的經驗中學習？ – ifaour 2011-03-04 08:02:30

你好老兄此代碼對我的作品完全一樣。你的代碼是什麼，它會將帖子發佈到你的相冊或應用程序相冊中。

 
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); 
     } 
    } 
    /**/ 

}

當您從應用程序上傳任何圖片時，facebook會在您的應用程序配置文件中創建一個相冊。但是這段代碼會將照片發佈到你的相冊中。

$_POST['album']

是我在文本框中輸入的專輯名稱。然後，我只需發佈表單並上傳照片。我希望這會幫助你

感謝您的協助。我相信我的設置有問題。不太清楚爲什麼我的工作不能繼續。但非常感謝你的幫助。 – meAtStackOverflow 2011-03-04 07:14:43

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

請添加一些細節以使您的答案更有用。 – akjoshi 2013-01-08 12:04:41

更換getSession()與getUser() 因爲舊的PHP版本不識別getSession()功能。
