Facebook Graph API，扩展权限(Facebook Graph API, extended permissions)

 我正在尝试使用facebook Graph API来更新用户staus消息。 
 
 我在使用它时遇到以下错误，我认为新的图形sdk没有被正确引用？ 
 
Notice: Undefined property: Facebook::$api_client in /users/home/aafhe7vh/web/public/update.php  on line 9

Fatal error: Call to a member function users_hasAppPermission() on a non-object in /users/home/aafhe7vh/web/public/update.php on line 9
 
 这是我正在使用的文件http://github.com/facebook/php-sdk/blob/master/src/facebook.php 
 
 以下是我的update.php的内容： 
 
 
# <?php  

  include_once ('facebook.php');
  $api_key = '@@@@@@@@@@@@@@@@@@@2';
  $secret  = '$$$$$$$$$$$$$$$$$$$$44';
  global $facebook;
  $facebook = new Facebook($api_key, $secret);

# include_once("config.php");  
# if (!$facebook->api_client->users_hasAppPermission("status_update")){  
# echo '<fb:prompt-permission perms="status_update" next_fbjs="greet()">Let us update your status </fb:prompt-permission>';  
# $visibility = "none";  
# }  
# else  
# $visibility = "block";  
#   
# if(isset($_POST['hello']))  
# {  
#     $facebook->api_client->users_setStatus($_POST['hello']);  
#     echo "<p>Your status has been updated</p>";  
# }  
# ?>  
# <div id="statusdiv" style="display:<?=$visibility;?>;">  
#     <form method="POST">  
#         Please update your status:<br/>  
#         <input type="text" name="status" /> <br/>  
#         <input type="submit" value="change status" />  
#     </form>  
# </div>  
#   
# <script>  
# 
function greet()  
# {  
#     var session = "<?=$facebook->api_client->session_key;?>";  
#     document.getElementById("statusdiv").setStyle("display","block");  
#     new Dialog().showMessage("Info","Thank you for granting us this permission! ");  
# }  
</script>
 
 我在这里使用了上面的代码， http：//fbcookbook.ofhas.in/tag/extended-permission/ 
 
 我不确定config.php应该包含什么，所以我在代码中删除了该行。 
 
 谢谢。 

I am trying to use facebook Graph API, to update a users staus message. 
 
I am getting the following error while using it, I think the new graph sdk is not being properly referenced ?
 
Notice: Undefined property: Facebook::$api_client in /users/home/aafhe7vh/web/public/update.php  on line 9

Fatal error: Call to a member function users_hasAppPermission() on a non-object in /users/home/aafhe7vh/web/public/update.php on line 9
 
This is the file I am using http://github.com/facebook/php-sdk/blob/master/src/facebook.php
 
Following is the content of my update.php:
 
 
# <?php  

  include_once ('facebook.php');
  $api_key = '@@@@@@@@@@@@@@@@@@@2';
  $secret  = '$$$$$$$$$$$$$$$$$$$$44';
  global $facebook;
  $facebook = new Facebook($api_key, $secret);

# include_once("config.php");  
# if (!$facebook->api_client->users_hasAppPermission("status_update")){  
# echo '<fb:prompt-permission perms="status_update" next_fbjs="greet()">Let us update your status </fb:prompt-permission>';  
# $visibility = "none";  
# }  
# else  
# $visibility = "block";  
#   
# if(isset($_POST['hello']))  
# {  
#     $facebook->api_client->users_setStatus($_POST['hello']);  
#     echo "<p>Your status has been updated</p>";  
# }  
# ?>  
# <div id="statusdiv" style="display:<?=$visibility;?>;">  
#     <form method="POST">  
#         Please update your status:<br/>  
#         <input type="text" name="status" /> <br/>  
#         <input type="submit" value="change status" />  
#     </form>  
# </div>  
#   
# <script>  
# 
function greet()  
# {  
#     var session = "<?=$facebook->api_client->session_key;?>";  
#     document.getElementById("statusdiv").setStyle("display","block");  
#     new Dialog().showMessage("Info","Thank you for granting us this permission! ");  
# }  
</script>
 
I used the above code from here , http://fbcookbook.ofhas.in/tag/extended-permission/
 
I am not sure what the config.php should contain so I have removed that line in my code. 
 
Thanks.
