Facebook API sdk 4.0 - post a photo onto facebook

Question

I am trying to create an application where the user can browse and submit a photo from their computer onto their facebook. For this, they will first have to upload their photo o

Answer 1

Assuming that the user has correctly uploaded the image and $location.$name is the path:

 $request = new FacebookRequest(
     $session,
     'POST',
     '/me/photos',
     array (
        'source' => file_get_contents($location.$name),
     )
  );

 $response = $request->execute();
 $graphObject = $response->getGraphObject();

Or another possibility is via URL:

 $request = new FacebookRequest(
   $session,
   'POST',
   '/me/photos',
   array (
     'url' => $the_url_to_the_image,
   )
 );

 $response = $request->execute();
 $graphObject = $response->getGraphObject();

And the API call you do AFTER the upload is done by the user but that is not more than logical.
