Facebook Developers - Summary of likes requested but API keeps returning just a list of likes - any idea why?? Works fine in the Explorer?
At present I'm trying to write a php plugin that will tell me the number of likes a particular feed has.
I want to use the likes[total_count] field which needs the summary flag set.
I have the following code
$fb = new Facebook\Facebook ( /* app id/secret, etc*/ ) ;
/* the access token is appid|appsecret and it's a public page*/
$fb->setDefaultAccessToken ( $w->accessToken () ) ;
$response = $fb->get ('/xxxxx_xxxxx?fields=likes.limit(1).summary(true),id' ) ;
$graphObject = $response->getGraphObject();
print_r ( $graphObject->asArray () ) ;
The result is
Array (
[likes] => Array (
[0] => Array ( [id] => xxxxxx )
[id] => xxxxx_xxxxx )
I've also tried a number of other things like getGraphNode() (same result), getGraphEdge () (error 620 - response is not GraphEdge - which I was expecting anyway!), I've also tried it with and without the .limit(1) the only difference being I just get more like id's - so the limit seems to be working it's just summary isn't.
When I try the same thing in Graph API Explorer on the facebook developer page I get the following result
"likes": {
"data": [
{
"id": "xxxx"
}
],
"paging": {
"cursors": {
"after": "MTAxNTU4NjU4ODY0NDA0MjI=",
"before": "MTAxNTI0MTQ2NjY2ODIxODc="
}
},
"summary": {
"total_count": 6,
"can_like": true,
"has_liked": false
}
In the API Explorer there is an additional array called summary which I can't see in my array.
Yahoo answers truncated the important line of code to ... which should read
$response = $fb->get ('/390458134468686_541172056063959?fields=likes
.summary(true),id' ) ;
Anyone any idea why on earth I can't access the summary array - do I have to do something else? maybe make a call to another function to get a summary or something?
ok just found out that this code works to get the total count
$graphObject = $response->getGraphNode();
$edge = $graphObject->getField ('likes' ) ;
$total_count = $edge->getMetaData()['summary']['total_count'] ;
omg seriously is this the only way to get the total_count??? Seems very long winded just to get a bit of data that should be quite easy to obtain!!
Thanks Chris - I was originally using json_decode but getting exactly the same thing - seems the only way to get a summary is to get the edge and then the metadata!
