Answer 1

Something is wrong/odd with your opening brace in your second if statement. This is the fixed version:

if ($operation == 'upload') {

    if(isset($data -> paper) && !empty($data -> paper) && isset($data -> paper -> author) && isset($data -> paper -> description) && isset($data -> paper -> title)) {

        $author = $data->paper->author;
        $description = $data->paper->description;
        $title = $data->paper->title;

        echo $fun->uploadPaper($author, $description, $title);

    }

}
