如何从iframe应用程序中获取用户细节?

the problem is when i try to authenticate the user it authenticating and redirecting to the SITE not to facebook .

事实上,如果像需要利用图表复制件(任何其他方式/javascript )获取用户细节,则使用已签名的“要求”检查用户喜欢或不喜欢。这样,就可以在数据库中节省费用。

This is my current code

if (isset($_REQUEST[ signed_request ]))
        {
            $encoded_sig = null;
            $payload = null;
            list($encoded_sig, $payload) = explode( . , $_REQUEST[ signed_request ], 2);
            $sig = base64_decode(strtr($encoded_sig,  -_ ,  +/ ));
            $data = json_decode(base64_decode(strtr($payload,  -_ ,  +/ ), true));
            if($data->page->liked)
            {
                //liked


                $questions = $this->functions->get_questions();

                if($questions["status"] ==TRUE)
                {
                    $questions["data"] = $questions["data"]->result_array();
                    $this->load->view("public/contest",$questions);


                }
                else
                {
                    echo "FALSE";
                }



            }
            else {

                //not liked

                $this->load->view("public/continue");



            }
        }

谢谢。

我建议使用Facebook SDK。这使你能够得到用户的帮助,然后询问图象对一些基本信息的影响。 http://developers.facebook.com
