now i want to get fields

*email 
*birth day

and some other permission requesting fields .

so i am doing

    $this->co_config_items = $this->ci->config->item('connections_config');
    $fbconfig = array(
    'appId' => $this->co_config_items['fb_appid'],
    'secret' => $this->co_config_items['fb_secret'],
    'cookie' => true,
    'domain' => $this->ci->config->item('domain')
    );

    $this->ci->load->library('3rd/connectors/facebook', $fbconfig);

    $facebook = new Facebook($fbconfig);
    Facebook::$CURL_OPTS[CURLOPT_SSL_VERIFYPEER] = false;
    Facebook::$CURL_OPTS[CURLOPT_SSL_VERIFYHOST] = 2;

    $session = $facebook->getSession();

    $url = $facebook->getLoginUrl(array(
                   'canvas' => 1,
                   'fbconnect' => 0,
                   'scope' => 'read_stream,friends_likes,user_birthday'
    ));     

    if(!$session){
        $url = $facebook->getLoginUrl(array(
                   'canvas' => 1,
                   'fbconnect' => 0,
                   'scope' => 'read_stream,friends_likes,user_birthday'

                  ));

        echo "<script type='text/javascript'>window.location = '$url';</script>";
    }
    else{
        //echo "<script type='text/javascript'>window.opener.location.href='" . base_url() . "home/auth/get_user_facebook_details_list" . "'; self.close();
        //</script>";
        try {

            $me = $facebook->api('/me');

            $this->ci->session->set_flashdata ( 'user_details',$me);
            $url=base_url()."home/auth/user_contact_information";               
            echo "<script type='text/javascript'>window.opener.location.href = '$url';self.close();</script>";

        } catch (FacebookApiException $e) {
            $this->ci->message->set_error(array('An errror occured , please try again'));
        }
    }

i am trying to ask permissions by

        $url = $facebook->getLoginUrl(array(
                       'canvas' => 1,
                       'fbconnect' => 0,
                       'scope' => 'read_stream,friends_likes,user_birthday'
)):

but it is not asking for any permission , the default array is always printing . why is that . please help . thanks in advance

Answer 1

i was using the version 2 of PHP sdk , now i am using version 3 , now it is working , thank you very much . i saw some changes in two versions in this function

version 2

  public function getLoginUrl($params=array()) {
        $currentUrl = $this->getCurrentUrl();
        return $this->getUrl(
                'www',
                'login.php',
                array_merge(array(
                    'api_key' => $this->getAppId(),
                    'cancel_url' => $currentUrl,
                    'display' => 'page',
                    'fbconnect' => 1,
                    'next' => $currentUrl,
                    'return_session' => 1,
                    'session_version' => 3,
                    'v' => '1.0',
                        ), $params)
        );
    }

version 3

 public function getLoginUrl($params=array()) {
    $this->establishCSRFTokenState();
    $currentUrl = $this->getCurrentUrl();

    // if 'scope' is passed as an array, convert to comma separated list
    $scopeParams = isset($params['scope']) ? $params['scope'] : null;
    if ($scopeParams && is_array($scopeParams)) {
      $params['scope'] = implode(',', $scopeParams);
    }

    return $this->getUrl(
      'www',
      'dialog/oauth',
      array_merge(array(
                    'client_id' => $this->getAppId(),
                    'redirect_uri' => $currentUrl, // possibly overwritten
                    'state' => $this->state),
                  $params));
  }

in version 3 this i can see this additional code

// if 'scope' is passed as an array, convert to comma separated list
    $scopeParams = isset($params['scope']) ? $params['scope'] : null;
    if ($scopeParams && is_array($scopeParams)) {
      $params['scope'] = implode(',', $scopeParams);
    }

in version 2 , there is nothing called scope .and also

in version 2

return $this->getUrl(
                    'www',
                    'login.php',

in version 3

return $this->getUrl(
          'www',
          'dialog/oauth',
