Example on how to connect with your user system
table for providers:
--
-- Structure for table `social`
--
DROP TABLE IF EXISTS `social`;
CREATE TABLE IF NOT EXISTS `tbl_social` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`yiiuser` int(11) NOT NULL,
`provider` varchar(50) NOT NULL,
`provideruser` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
Use gii to create the the model file.
In Your UserIdentity model (usually protected/components unless u have some user module)
public function hybridauth($username)
{
$user=User::model()->find("username = '" . $username . "'");
if ( $user === null )
$this->errorCode = self::ERROR_USERNAME_INVALID;
else
{
$this->_id = $user->id;
$this->username = $user->username;
$this->errorCode = self::ERROR_NONE;
}
return $this->errorCode == self::ERROR_NONE;
}
and for simplicity to make the example the new protected/modules/yiiauth/controllers/DefaultController.php
Its probably bad practise to put all the methods in here but its example demo so…
<?php
class DefaultController extends Controller
{
public function actionIndex(){
$this->renderPartial('index');
}
public function actionauthenticatewith( $provider="" ) {
require_once( '/hybridauth/Hybrid/Auth.php' );
$hybridauth_config = $this->hybridAuthConfig();
$error = false;
$user_profile = false;
try{
// create an instance for Hybridauth with the configuration file path as parameter
$hybridauth = new Hybrid_Auth( $hybridauth_config );
// try to authenticate the selected $provider
if ( isset( $_GET['openid'] ) ){
$provider = "openid";
$adapter = $hybridauth->authenticate( $provider,array( "openid_identifier" => $_GET['openid'] ) );
}else{
$adapter = $hybridauth->authenticate( $provider );
}
// grab the user profile
$user_profile = $adapter->getUserProfile();
}
catch( Exception $e ){
// Display the recived error
switch( $e->getCode() ){
case 0 : $error = "Unspecified error."; break;
case 1 : $error = "Hybriauth configuration error."; break;
case 2 : $error = "Provider not properly configured."; break;
case 3 : $error = "Unknown or disabled provider."; break;
case 4 : $error = "Missing provider application credentials."; break;
case 5 : $error = "Authentification failed. The user has canceled the authentication or the provider refused the connection."; break;
case 6 : $error = "User profile request failed. Most likely the user is not connected to the provider and he should to authenticate again.";
$adapter->logout();
break;
case 7 : $error = "User not connected to the provider.";
$adapter->logout();
break;
}
// well, basically your should not display this to the end user, just give him a hint and move on..
$error .= "<br /><br /><b>Original error message:</b> " . $e->getMessage();
$error .= "<hr /><pre>Trace:<br />" . $e->getTraceAsString() . "</pre>";
}
/**$user_profile->identifier; //unique id
$provider; // the provider name
$_GET['openid'];//the extra_info
**/
// workOnUser returns an user object
$user = $this->workOnUser($provider,$user_profile->identifier);
if ( $this->autoLogin($user) ){
$this->render('profile',
array(
'error'=>$error,
'provideruser'=>$user_profile,
'yiiuser'=>$user,
'provider'=>$provider,
) );
}else{
$this->render('authenticatewith',array('error'=>$error,'user_profile'=>$user_profile ) );
}
}
public function workOnUser($provider,$provideruser){
$social = Social::model()->find("provider='".$provider."' AND provideruser='".$provideruser."'");
if ( $social ){
$user = User::model()->find("id=".$social->yiiuser);
return $user;
}else{
// we want to create a new user, but since we get no user input the validation rules will cause
//errors on save to counter this i added 'on'=>'validation' to all my user validation rules
//example: array('username, password', 'required','on'=>'validation'),
// on normal user registration with user input I use: new User('validation')
$user = new User;
$user->username = $provideruser;
if ( $user->save() ){ //we get an user id
//add a social connection between the newly created yii user and the provider user account to avoid double regestrations and enable the same yii user to have many providers associated with it.
$social = new Social;
$social->yiiuser = $user->id;
$social->provider = $provider;
$social->provideruser = $provideruser;
if($social->save())
return $user;
}
}
}
public function autoLogin($user) //accepts a user object
{
$identity=new UserIdentity($user->username, "");
$identity->hybridauth($user->username);
if ( $identity->errorCode == UserIdentity::ERROR_NONE )
{
$duration= 3600*24*30; // 30 days
Yii::app()->user->login($identity,$duration);
return true;
}
else
{
echo $identity->errorCode;
return false;
}
}
}?>
then create protected/modules/yiiauth/views/default/profile.php
<?php
if( isset( $error ) ){
echo $error;
}
echo $yiiuser->id. "<br/>"; // the yii user id
echo $yiiuser->username."<br/>"; // the yii user name
echo $provider ."<br/>"; // provider,twitter,fb etc
var_dump($provideruser); //the object with all info u mby want to use from the provider
?>
I developed my user system for one app and its still pretty tight to that app, meaning If I moved it all to another app I would get a shitload of tiny errors like missing variables etc. So I have to clear all this outh.
