Facebook API sdk 4.0 – отправить фотографию на facebook

Я пытаюсь создать приложение, в котором пользователь может просматривать и отправлять фотографии со своего компьютера на свою электронную почту. Для этого им сначала нужно будет загрузить свою фотографию на сервер, а затем воспользоваться запросом facebook, разместив это изображение на facebook. Я использую multipart / form-data.

Это то, что у меня до сих пор для этого, предполагая, что у меня есть действующий сеанс, мой запрос api:

$request = new Facebook{ $session, 'POST', '/me/photos', array ( 'source' => '{image-data}', ) ); $response = $request->execute(); $graphObject = $response->getGraphObject(); /* handle the result*/ 

Я не уверен, что заменить изображения-данные.

Для загрузки фотографии мой код выглядит следующим образом:

• CodeIgniter Facebook SDK 4 с композитором
• Facebook PHP SDK v4.0 FacebookJavaScriptLoginHelper возвращает состояние NULL

  if(isset($_POST['submit'])){ $file_type = $_FILES['file']['type']; //returns the file type $allowed = array("image/jpeg", "image/gif", "image/png", "image/jpg"); //specifies allowed file types if(!in_array($file_type, $allowed)) { $error_message = 'Only jpeg, jpg, gif, and png files are allowed. <br> Please click back and try again.'; echo $error_message; exit(); } $name = $_FILES['file']['name']; //original path of the uploaded file $temp_name = $_FILES['file']['tmp_name']; //contains the path to the temporary file that resides on the server if(isset($name)){ if(!empty($name)){ $location = 'uploads/'; //save photo to the folder: uploads if(move_uploaded_file($temp_name, $location.$name)){ echo 'Photo was successfully uploaded.'; } } } else { echo 'Photo was unsuccessfully uploaded, click back and try again.'; } } 

Я новичок в facebook api и новичок в кодировании. Любая помощь или совет будут высоко оценены. Благодарю.

Весь код:
