Question

我有这个代码，如果我提供图像的直接链接，它的工作非常好。

只是一个问题我无法将我上传的图像传递给facebook-＆gt; api（无论是否有效）以及以下内容始终回显

echo'仅支持jpg，png和gif图像类型！';

我甚至删除了对图像类型的检查并尝试从中获取图像 $ img = realpath（$ _ FILES [“pic”] [“tmp_name”]）; 但$ img没有任何内容，并在Facebook上作为我的页面上传默认的空图像请检查我的以下代码，让我知道我的代码有什么问题，我该怎么办才能上传图片

 <?


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!';
 }

  #Upload photo here
  $img = realpath($_FILES["pic"]["tmp_name"]);
