Can you push seri auto like facebook Grap api for people?

Awesome video

What would we do without you?

to retrieve using php you can go this route see code below

require_once( 'C:fakepathvendorfacebookgraph-sdksrcFacebookautoload.php' );

class Facebook {

public $ci;

public $accessToken;

public $fb;

public function __construct() {

// Get CI object.

$this->ci =& get_instance();

$this->fb = new FacebookFacebook([

'app_id' => *"your-app-id"*,

'app_secret' => *"your-app-secret"*,

'default_graph_version' => 'v2.10',

//'default_access_token' => '{access-token}', // optional

]);

}

public function login(){

$helper = $this->fb->getRedirectLoginHelper();

$permissions = ['email','publish_to_groups','publish_pages'];
//you can visit the facebook page and add more scopes
$loginUrl = $helper->getLoginUrl(base_url('/client/FaceBookHandler'), $permissions);

echo '<script>window.open("'.$loginUrl.'", "Facebook Popup", "height=500,width=400,resizable=no");</script>';
//custom popup window
}

public function getAccessToken(){

$helper = $this->fb->getRedirectLoginHelper();

$accessToken = '';

try {

$accessToken = $helper->getAccessToken();

} catch(FacebookExceptionsFacebookResponseException $e) {

return false;

} catch(FacebookExceptionsFacebookSDKException $e) {

return false;

}

$oAuth2Client = $this->fb->getOAuth2Client();

$tokenMetadata = $oAuth2Client->debugToken($accessToken);

$tokenMetadata->validateAppId("*your-app-id*");

$tokenMetadata->validateExpiration();

if (! $accessToken->isLongLived()) {

try {

$accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);

} catch (FacebookExceptionsFacebookSDKException $e) {

return false;

}

}

if(isset($accessToken) && !empty($accessToken)){

return $accessToken;

}

return false;

}

/*Seeting the access token */
public function setAccessToken($token){

//$_SESSION['fb_access_token'] = (string) $accessToken;

$_SESSION['fb_access_token'] = (string) $token->getValue();

$_SESSION['fb_expires_at'] = strtotime($token->getExpiresAt()->format('Y-m-d H:i:s'));

try {

$response = $this->fb->get('/me?fields=id,name', (string) $token->getValue());

} catch(FacebookExceptionsFacebookResponseException $e) {

return false;

} catch(FacebookExceptionsFacebookSDKException $e) {

return false;

}

$user = $response->getGraphUser();

$_SESSION['fb_user_id'] = $user->getId();

return array(

'fb_access_token'=>(string) $token->getValue(),

'fb_expires_at'=>strtotime($token->getExpiresAt()->format('Y-m-d H:i:s')),

'fb_user_id',$user->getId());

}

}

/*Testing the code*/
public function RequestBlogs(){

// echo "my user id = ".$_SESSION['fb_user_id'];

echo $this->face->login();

}

public function FaceBookHandler(){

$token = $this->face->getAccessToken();

if($token != false){

$result = $this->face->setAccessToken($token);

if($result != false){

print_r($result);

}else{

echo "Failed to set access token";

}

}else{

echo "Login Failed";

}
