Bogardo\Multiauth

Laravel authentication driver which enables you to use multiple Eloquent models for authentication.

This package supports Laravel's password reminders by default and needs no extra configuration.

Installation

Currently only compatible with Laravel 4.2
Support for Laravel 5 is on the roadmap

Install the package with composer

$ composer require bogardo\multiauth

Add the service provider

Add the following to your providers array in app/config/app.php

'Bogardo\Multiauth\MultiauthServiceProvider',

Configuration

Change the following in your app/config/auth.php file.

Set your driver to multiauth

'driver'    => 'multiauth'

Add your multiauth settings

'multiauth' => [
 
    'identifier_key' => 'email',

    'entities' => [
        [
            'type'       => 'user',
            'table'      => 'users',
            'model'      => 'User',
            'identifier' => 'username'
        ],
        [
            'type'       => 'administrator',
            'table'      => 'admins',
            'model'      => 'Admin',
            'identifier' => 'email'
        ]
    ]
]

Usage

Prepare your models

There are 2 things that must be changed in your models

1. Add the Bogardo\Multiauth\User\UserTrait (replace it if it is already present)
   
2. Add a public $authtype property. The value of the property should match the type key defined in the multiauth configuration.

Examples

User model

use Bogardo\Multiauth\User\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface
{

    use UserTrait, RemindableTrait;

    public $authtype = 'user';
    
}

Admin model

use Bogardo\Multiauth\User\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class Admin extends Eloquent implements UserInterface, RemindableInterface
{

    use UserTrait, RemindableTrait;

    public $authtype = 'administrator';
    
}

Validation

When working with just one table for users you'd normally only check for unique emails/usernames in your users table. But when you're working with multiple tables you have to make sure that your emails/usernames are unique on all relevant tables.

This package provides a convient validation rule to do exactly that.

It will check if the supplied value (email/username) exists on any of the tables defined in the multiauth configuration. It will take note of the identifier (email/username/custom) defined in the configuration.

When using the rule without extra parameters it will make sure the supplied value does not exist in any of the tables. You'd probably use this for creating new users.

multiAuthUnique

When updating an existing user you'd want to check if the supplied value is unique except for the record you are updating. You can do this by supplying two parameters:

• The type of the user being updated
• The id of the user being updated

multiAuthUnique:user,2

Usage

Creating new record

Validator::make(
    ['email' => '[email protected]'], // data array
    ['email' => 'multiAuthUnique']    // rules array
);

Updating an existing Admin user with an id of 5

Validator::make(
    ['email' => '[email protected]'],              // data array
    ['email' => 'multiAuthUnique:administrator,5'] // rules array
);

API

Get the Multiauth service

/** @var Bogardo\Multiauth\Service $service */
$service = App::make('multiauth.service');

Get a collection of all registered entities The EntityCollection extends Laravel's Collection

$entities = $service->getEntities();

// $entities Output
object(Bogardo\Multiauth\Entity\EntityCollection)
  protected 'items' => 
    array (size=2)
	   0 => 
        object(Bogardo\Multiauth\Entity\Entity)
          public 'type' => string 'user'
          public 'table' => string 'users'
          public 'model' => string 'User'
          public 'identifier' => string 'username'
      1 => 
        object(Bogardo\Multiauth\Entity\Entity)
          public 'type' => string 'administator'
          public 'table' => string 'admins'
          public 'model' => string 'Admin'
          public 'identifier' => string 'email'
      

Get an entity by type

$entity = $service->getEntityByType('user');

// $entity Output
object(Bogardo\Multiauth\Entity\Entity)
  public 'type' => string 'user'
  public 'table' => string 'users'
  public 'model' => string 'User'
  public 'identifier' => string 'username'

Filters example implementation

You could use this, for example, to create custom route filters for each user type.

/** @var Bogardo\Multiauth\Service $service */
$service = App::make('multiauth.service');
$types = $service->getEntities()->lists('type');

foreach ($types as $type) {
    Route::filter('multiauth.' . $type, function($route, $request) use ($type) {

        if (Auth::guest()) {
            // The user is not logged in.
            return Redirect::to('/');
        }

        if (Auth::user()->authtype !== $type) {
            // The user is logged in, but is not of correct type
            return Redirect::to('/');
        }
    });
}

This will create a route filter for every registered user type:

• user: multiauth.user
• administrator: multiauth.administrator

Which you could use to restrict access to a route which should only be accessible for a specific user type.

Route::get('admin', ['before' => 'multiauth.administrator', function() {
    echo 'Admins Only!!';
}]);

FAQ

- I'm unable to login using the loginUsingId and onceUsingId methods

The loginUsingId() and onceUsingId() methods should be passed the type and the id of the user, separated by a dot. This deviates from the default usage, where you'd only have to pass the ID of the user.

Auth::loginUsingId('administrator.2');

Auth::onceUsingId('user.54')
