可能重复：
将上传的图像传递给 facebook->api 函数的 PHP SCRIPT 问题

我有这段代码，它的工作非常好，只有一个问题我无法将我上传的图像传递给 facebook->api（无论它是否有效），以下总是回显 echo 'Only jpg、png 和 gif 图像支持类型！'; 我什至删除了对图像类型的检查并尝试从 $img = realpath($_FILES["pic"]["tmp_name"]); 但是 $img 什么都没有，并默认在 facebook 上上传一个空图像作为我的页面 请检查我的以下代码，让我知道我的代码应该有什么问题，这样我就可以上传图像了

 <?


require 'src/facebook.php';

$app_id = "364900470214655";
$app_secret = "xxxxxxxx";

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

$user = $facebook->getUser();
//echo $user;

if(($facebook->getUser())==0)
{
 header("Location:{$facebook->getLoginUrl(array('req_perms' => 'user_status,publish_stream,user_photos,offline_access,manage_pages'))}");
 exit;
}
else {
$accounts_list = $facebook->api('/me/accounts');
echo "i am connected";
}
  $valid_files = array('image/jpeg', 'image/png', 'image/gif');


//to get the page access token to post as a page
foreach($accounts_list['data'] as $account){
      if($account['id'] == 194458563914948){      // my page id =123456789
        $access_token = $account['access_token'];
        echo "<p>Page Access Token: $access_token</p>";
        }
    }

//posting to the page wall

if (isset($_FILES) && !empty($_FILES))
{  
if( !in_array($_FILES['pic']['type'], $valid_files ) )
{
  echo 'Only jpg, png and gif image types are supported!';
 }
 else{
  #Upload photo here
  $img = realpath($_FILES["pic"]["tmp_name"]);
$attachment = array('message' => 'this is my message',
                'access_token'  => $access_token,
                'name' => 'This is my demo Facebook application!',
                'caption' => "Caption of the Post",
                'link' => 'example.org',
                'description' => 'this is a description',
                'picture' => '@' . $img,
                'actions' => array(array('name' => 'Get Search',
                                  'link' => 'http://www.google.com'))
                );
$status = $facebook->api('/194458563914948/feed', 'POST', $attachment);   // my page id =123456789
var_dump($status);
}
}
?>

创建新相册并添加照片

这是您将照片上传到 ALBUM_ID/photos Graph API 端点的场景。此示例的用户界面允许用户在提交新照片之前选择照片并添加标题。

使用 PHP：

<?php

       $app_id = "YOUR_APP_ID";
       $app_secret = "YOUR_APP_SECRET";
       $post_login_url = "YOUR_POST-LOGIN_URL";
       $album_name = 'YOUR_ALBUM_NAME';
       $album_description = 'YOUR_ALBUM_DESCRIPTION';

       $code = $_REQUEST["code"];

       //Obtain the access_token with publish_stream permission 
       if(empty($code))
         {
           $dialog_url= "http://www.facebook.com/dialog/oauth?"
           . "client_id=" . $app_id 
           . "&redirect_uri=" . urlencode($post_login_url)
           . "&scope=publish_stream";
           echo("<script>top.location.href='" . $dialog_url . 
           "'</script>");
       } 
       else {
         $token_url= "https://graph.facebook.com/oauth/"
         . "access_token?"
         . "client_id=" .  $app_id 
         . "&redirect_uri=" . urlencode( $post_login_url)
         . "&client_secret=" . $app_secret
         . "&code=" . $code;
         $response = file_get_contents($token_url);
         $params = null;
         parse_str($response, $params);
         $access_token = $params['access_token'];

         // Create a new album
         $graph_url = "https://graph.facebook.com/me/albums?"
         . "access_token=". $access_token;

         $postdata = http_build_query(
         array(
          'name' => $album_name,
          'message' => $album_description
            )
          );
         $opts = array('http' =>
         array(
          'method'=> 'POST',
          'header'=>
            'Content-type: application/x-www-form-urlencoded',
          'content' => $postdata
          )
         );
         $context  = stream_context_create($opts);
         $result = json_decode(file_get_contents($graph_url, false, 
           $context));

         // Get the new album ID
         $album_id = $result->id;

         //Show photo upload form and post to the Graph URL
         $graph_url = "https://graph.facebook.com/". $album_id
           . "/photos?access_token=" . $access_token;
         echo '<html><body>';
         echo '<form enctype="multipart/form-data" action="'
         .$graph_url. ' "method="POST">';
         echo 'Adding photo to album: ' . $album_name .'<br/><br/>';
         echo 'Please choose a photo: ';
         echo '<input name="source" type="file"><br/><br/>';
         echo 'Say something about this photo: ';
         echo '<input name="message" type="text"
            value=""><br/><br/>';
         echo '<input type="submit" value="Upload" /><br/>';
         echo '</form>';
         echo '</body></html>';
      }
 ?>
