Posting on a Facebook page with PHP SDK v5

I followed this guide to automatically post content to Facebook page.

Here is the sequence of steps:

1. Check to see if the user is authorized to use the application


2. Get single-use access token


3. Back on a callback url and save a session called facebook_access_token



4. In the last function, I establish the parameters for sending on Facebook. If I follow the guide above, I put :

   
   
   

   $data = array(
       'message' => 'Message',
       'link' => 'http://www.example.com',
       'picture' => 'http://www.example.com/images/test.png',
       'name' => 'Title',
       'caption' => 'www.example.com',
       'description' => 'Description'
     );
   
   # POST request in v5
   $response = $this->fb->post('/'.$this->appId.'/feed', $data, Session::get('facebook_access_token'));
   

   
   
   

   And I'm getting the following error :

   
   
   

   FacebookResponseException in FacebookResponseException.php line 108:
   Unsupported post request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api
   

   
   
   

   If I follow the Graph API Explorer directly proposed on the Facebook developers site, I put the same parameters as before (message, caption, etc ...) and then generates the code, I get this :

   
   
   

   $request = new FacebookRequest(Session::get('facebook_access_token'), 'POST', '/'.$this->appId.'/feed', array(
       'message' => 'Message',
       'link' => 'http://www.example.com',
       'picture' => 'http://www.example.com/images/test.png',
       'name' => 'Title',
       'caption' => 'www.example.com',
       'description' => 'Description'
     )
   );
   
   $response = $request->execute();
   $graphObject = $response->getGraphObject();
   

   
   
   

   Here I'm getting this error :

   
   
   

   ErrorException in FacebookUrlManipulator.php line 109:
   parse_url() expects parameter 1 to be string, array given
   

How to solve this problem?
