Facebook API-发布照片并同时链接到墙上

Question

Is it possible to post image and link together? Here is my code :

try {
$facebook->setFileUploadSupport(true);

if(!isset($userLink)){
   $postResult = $facebook->api(
                  '/'.$userGroupId.'/photos/',
                  'post',
                  array(
                     'message' => $userMessage,
                     'source' => '@'.$_FILES["source"]["tmp_name"] ));
}else{
   $postResult = $facebook->api(
                  '/'.$userGroupId.'/photos/',
                  'post',
                  array(
                     'message' => $userMessage,
                     'link' => $userLink,
                     'source' => '@'.$_FILES["source"]["tmp_name"] ));
  }
}
catch (FacebookApiException $e) {
    error_log('Could not post image to Facebook.');
}

Without 'link' everything is ok, but if I insert link into array i got an error : Notice: Undefined variable: postResult in..

Is there something wrong with my code? Please help, Thank you.

If you read the documentation , the link parameter is-

A link to the photo on Facebook (that you wish to upload)

But you are using it in another way, to share link along with the photo- which is not possible. For sharing a link on wall you have to use Feed instead.
