在facebook上发布图片用户的时间线

Question

我有一个使用Facebook PHP API的应用程序。这是我的代码的一部分，我不知道我做错了什么，或者我现在错过了什么。我似乎无法在Facebook上发布用户时间线上的图片。任何帮助将非常感激。非常感谢。

 <?php 
      echo "<p> Hello World!</p>"; 
     // php 5.3 and up can throw an error if this is not set 
     date_default_timezone_set("Europe/London");

您尚未设置上传文件。

$response = (new FacebookRequest(
           $session, 'POST', '/me/photos', 
            array(
             'source'=>'$IMAGE_FILENAME', 
             'message'=>'$IMAGE_MESSAGE' 
             ) 
               ))->execute()->getGraphObject(); 

您的报价，这将使它成为一个字符串包围的变量，因此源越来越文字串$ IMAGE_FILENAME

下面是一个简单的例子

$IMAGE_FILENAME='@images/Flower.jpg'; 
$IMAGE_MESSAGE='hello flower'; 

$arr = array(
    'source'=>'$IMAGE_FILENAME', 
    'message'=>'$IMAGE_MESSAGE' 
); 


$correct_arr = array(
    'source'=>$IMAGE_FILENAME, 
    'message'=>$IMAGE_MESSAGE 
); 

print_r($arr); 

print_r($correct_arr); 

响应

Array 
(
    [source] => $IMAGE_FILENAME 
    [message] => $IMAGE_MESSAGE 
) 
Array 
(
    [source] => @images/Flower.jpg 
    [message] => hello flower 
)
