Question

I would like to get an access token so I can check a user into a place using Facebook PHP SDK. How would I go about that?

Answer 1

The checkins connection is in the documentation

http://developers.facebook.com/docs/reference/api/user/

issuing an HTTP POST request to PROFILE_ID/checkins

Grab your $user

$user = $facebook->getUser();

Pass the publish_checkins permission in the scope array when you call the getLoginUrl call.

$loginUrl = $facebook->getLoginUrl(array('scope' => 'publish_checkins'));

Set up the data for the checkin

$checkin['post'] = array(
'access_token' => $facebook->getAccessToken(),
'place' => 'PLACE_ID',
'message' =>'Blank Message',
'picture' => 'http://www.example.com/picture.jpg',
'coordinates' => json_encode(array(
   'latitude'  => '_latitude',
   'longitude' => '_longitude',
   'tags' => $user),
 )
 );

Issue an API call to the PROFILE_ID in question,

$facebook->api('/'.$user.'/checkins', 'post', $checkin['post']);
