###Demo | Demo Source Code

• OpenID
• Google
• Facebook

Additional social networks providers can be found at HybridAuth website. And how to configure them here at the bottom of the page.

A little about how it's woks

The users of yii-user extension can skip this section, because hoauth will do all the stuff automatically. This extension authenticates and if it's need creates new user. When user was registered "locally" (so he has login (email) and password), then he can also log in with it's social account (extension checks if user with provided email exists in db, when yes, the he will be logged in and it is no matter how had he registered earlier - locally or not). After the user logged in he will be redirected to Yii::app()->user->returnUrl.

This extension requires UserIdentity class, but doesn't use authenticate() method of UserIdentity class. Class constructor called with parameters new UserIdentity($mail, null) and than called CWebUser::login() method (while authentication work did for us social network). When social network didn't give us user's email, the hoauth will ask user for email, when email exists in our db, the password will be asked too. At the end we bind provided by social network unique user identifier to user id for future sign in. Example of UserIdentity class.

If you need to perform some access check for user, you can use hoauthCheckAccess($user) callback (simply create new method in controller where you added HOAuthAction). This method will be called with one input argument - User model of the user being authorized. This method should return integer values (accessCode) depending on the scenario needed:

• 0 - user shouldn't get access
• 1 - user may login
• 2 - user may login, but not now (e.g. the email should be verified and activated) You can also not only return the accessCode, but also render the page with error or any information you need.

NOTE: This extension will also automatically create user_oauth table in your database. About it see "UserOAuth model" section.

Installation and Usage

• instruction for yii-user

1. Make hoauth directory in your extensions directory (or in any other directory you want) and copy the content files there. Directory structure example:

/protected/
   extesions/
      hoauth/
         hybridauth/
         messages/
         models/
         views/
         widgets/
         .gitignore
         CHANGELOG
         DummyUserIdentity.php
         HOAuthAction.php
         HOAuthAdminAction.php
         MIT-LICENSE.txt
         README.md
         UPGRADE.md

2. Edit your controller source code (eg. SiteController class with actionLogin() method) to add new actions:

class SiteController extends Controller
{
	/**
	 * Declares class-based actions.
	 */
	public function actions()
	{
		return array(
      'oauth' => array(
        // the list of additional properties of this action is below
        'class'=>'ext.hoauth.HOAuthAction',
        // Yii alias for your user's model, or simply class name, when it already on yii's import path
        // default value of this property is: User
        'model' => 'User', 
        // map model attributes to attributes of user's social profile
        // model attribute => profile attribute
        // the list of avaible attributes is below
        'attributes' => array(
          'email' => 'email',
          'fname' => 'firstName',
          'lname' => 'lastName',
          'gender' => 'genderShort',
          'birthday' => 'birthDate',
          // you can also specify additional values, 
          // that will be applied to your model (eg. account activation status)
          'acc_status' => 1,
        ),
      ),
      // this is an admin action that will help you to configure HybridAuth 
      // (you must delete this action, when you'll be ready with configuration, or 
      // specify rules for admin role. User shouldn't have access to this action!)
      'oauthadmin' => array(
        'class'=>'ext.hoauth.HOAuthAdminAction',
      ),
		);
	}
}

3. Add the findByEmail method to your user`s model class:

  /**
   * Returns User model by its email
   * 
   * @param string $email 
   * @access public
   * @return User
   */
  public function findByEmail($email)
  {
    return self::model()->findByAttributes(array('email' => $email));
  }

4. Visit your oauthadmin action (eg. http://yoursite.com/site/oauthadmin) to create the HybridAuth config. For your HybridAuth Endpoint URL use this: http://yoursite.com/site/oauth. After install you can leave install.php in your file system, while it's in Yii protected directory. But you must remove oauthadmin action, or make such rules, that give access only for admin users. Config file can be found at application.config.hoauth

5. Add social login widget to your login page view (you can use route property, when you placing your widget not in the same module/controller as your oauth action):

<?php $this->widget('ext.hoauth.widgets.HOAuth'); ?>

This widget can be switched to icon view using onlyIcons property. It may be also usefull the properties to adjust popup window size: popupWidth and popupHeight. See HOAuth.php file for details.

Optional: 6. When you planning to use social networks like Twitter, that returns no email from user profile, you should declare verifyPassword($password) or validatePassword($password) method in User model, that should take the password (not hash) and return true if it is valid. 7. You can also declare the sendActivationMail() method, that should mark the user account as inactive and send the mail for activation. This method, when it's exists will be used for social networks like Twitter, that give us no data about user's email (because we need to proof that user entered the right email).

Note

If you want to correctly display the facebook popup, you should add "display" => "popup" to the Facebook configuration array in protected/config/hoauth.php. E.g.:

...
"Facebook" => array ( 
  "enabled" => true,
  "keys"    => array ( "id" => "PUT_YOURS_HERE", "secret" => "PUT_YOURS_HERE" ), 
  "scope"   => "email, user_about_me, user_birthday, user_hometown", // you can change the data, that will be asked from user
  "display" => "popup" // <- this one
)
...

Available social profile fields

You can find them at HybridAuth website. And here is some additional fields, that I needed in my project, you can use them too:

• birthDate - The full date of birthday (eg. 1991-09-03)
• genderShort - short representation of gender (eg. 'm', 'f')

Additional properties for HOAuthAction

• useYiiUser - enables support for yii-user (default: false). hoauth will find yii-user module automatically, so you can leave this property as default. You may also leave attributes and model properties as default.
• enabled - defines whether the ouath functionality is active. Useful for example for CMS, where user can enable or disable oauth functionality in control panel. (default: true)
• scenario - scenario name for the $model (optional)
• loginAction - name of a local login action (should be in the same controller as oauth action). (default: 'actionLogin')
• duration - 'remember me' duration in ms. (default: 2592000 //30days)
• usernameAttribute - you can specify username attribute, when it must be unique (like in yii-user extension), that hoauth will try to validate it's uniqueness.
• alwaysCheckPass - flag to control password checking for the scenario, when when social network returned email of existing local account. If set to false user will be automatically logged in without confirming account with password. (default: true)

Available Callbacks

To make you able to customize the behavior of hoauth, it is provide some useful callbacks. Here the list of them:

• Controller::hoauthCheckAccess($user)
• Controller::hoauthAfterLogin($user)
• User::findByEmail($email
• User::verifyPassword($password) or User::validatePassword($password)
• User::sendActivationMail())

More about callbacks

UserOAuth model

UserOAuth model used to bind social services to user's account and to store session with social network profile. If you want to use this data (user profile) later, please use UserOAuth::getProfile() method:

$userOAuths = UserOAuth::model()->findUser(5); // find all authorizations from user with id=5
foreach($userOAuths as $userOAuth)
{
  $profile = $userOAuth->profile;
  echo "Your email is {$profile->email} and social network - {$userOAuth->provider}<br />";
}

or

$userOAuth = UserOAuth::model()->findUser(5, "Google"); // find all authorizations from user with id=5
$profile = $userOAuth->profile;
echo "Your email is {$profile->email} and social network - {$userOAuth->provider}<br />";

You can also use UserOAuth::profileCache property to access cached copy of the profile, without making any request to the social network. About how to use HybridAuth object you can read here.
