Auth is a module for the Yii PHP framework that provides a web user interface for Yii's built-in authorization manager (CAuthManager). You can read more about Yii's authorization manager in the framework documentation under Authentication and Authorization.

Auth was developed to provide a modern and responsive user interface for managing user permissions in Yii projects. To achieve its goals it was built using my popular Twitter Bootstrap extension.

Auth is written according to Yii's conventions and it follows the separation of concerns priciple and therefore it doesn't require you to extend from its classes. Instead it provides additional functionality for the authorization manager through a single behavior.

You can try out the live demo here.

• Twitter Bootstrap extension for Yii version 2.0.0 or above

Unzip the module under protected/modules/auth and add the following to your application config:

return array(
  'modules' => array(
    'auth',
  ),
  'components' => array(
    'authManager' => array(
      .....
      'behaviors' => array(
        'auth.components.AuthBehavior',
      ),
    ),
  ),
);

protected/config/main.php

Please note that while the module doesn't require you to use a database, if you wish to use CDbAuthManager you need it's schema (it can be found in the framework under web/auth).

Configure the module to suit your needs. Here's a list of the available configurations (with default values).

'auth' => array(
  'strictMode' => true, // when enabled authorization items cannot be assigned children of the same type.
  'users' => array('admin'), // a list of users who has access to the module.
  'userClass' => 'User', // the name of the user model class.
  'userIdColumn' => 'id', // the name of the user id column.
  'userNameColumn' => 'name', // the name of the user name column.
  'appLayout' => 'application.views.layouts.main', // the layout used by the module.
  'viewDir' => null, // the path to view files to use with this module.
),

To enable caching for CDbAuthManager you can use CachedDbAuthManager that provides caching for access checks. Here's an example configuration for the component:

'authManager'=>array(
  'class'=>'auth.components.CachedDbAuthManager',
  'cachingDuration'=>3600,
),

When you wish to check if the current user has a certain permission you can use the CWebUser::checkAccess() method which can be access from anywhere in your application through Yii::app() like so:

if (Yii::app()->user->checkAccess('itemName')) // itemName = name of the operation
{
  // access is allowed.
}

In order to keep your permissions dynamic you should never check for a specific role or task, instead you should always check for an operation. For more information on Yii's authorization manager refer to the framework documentation on Authentication and Authorization.

You can also use a filter to automatically check access before controller actions are called. Operations used with this filter has to be named as follows (moduleId.)controllerId.actionId, where moduleId is optional. You can also use a wildcard controllerId.* instead of the actionId to cover all actions in the controller.

public function filters()
{
  return array(
    array('auth.components.AuthFilter'),
  ),
}

For more information on how filters work refer to the framework documentation on Controllers.

If you wish to allow certain users to access all content without any restrictions you can use the AuthWebUser component. Here's an example configuration for the component:

'user'=>array(
  'class'=>'auth.components.AuthWebUser',
  'admins'=>array('admin', 'foo', 'bar'),
),

Do you wish to provide a translation for Auth? If so, please do a pull request for it. Translations should be placed in the messages folder under a folder named according to its locale (e.g. en_us).
