Finally, add the following line to your routes.php file:<br />
Route::get('logout', 'auth@logout');<br />
That's all! Now, when we go to http://myfirst.dev/logout, we'll be logged out and<br />
redirected to our site's index page.<br />
So, how can we find out if someone is logged in? The Eloquent and Fluent Auth drivers contain<br />
two methods for handling this, check() and guest(). Let's look at each of these in turn:<br />
ÊÊ<br />
ÊÊ<br />
Auth::check() returns true if a user is currently logged in, and false otherwise.<br />
Auth::guest() is the opposite of Auth::check(). It returns false if a user is<br />
logged in, and true otherwise.<br />
Once you've made sure that a user is logged in, you can use Auth::user() to return the user<br />
record. If you're using the Fluent driver, Auth::user() will return a dumb object containing<br />
the appropriate values from the users table. If you're using the Eloquent driver, Auth::user()<br />
will return an instance of your <strong>User</strong> model. This is very powerful. Let's look at an example:<br />
@if(Auth::check())<br />
You're logged in as {{ Auth::user()->real_name<br />
}}<br />
@endif<br />
As you've seen, <strong>Laravel</strong>'s authentication system is driver-based. In this example, we used the<br />
Eloquent driver. However, you also have the ability to create custom authentication drivers. This<br />
gives you the power to authenticate users with different means and return different types of<br />
data with the standard Auth class' API. Covering the development of custom drivers is outside<br />
the scope of this document. However, it's simple and powerful. Be sure to look into the <strong>Laravel</strong><br />
documentation for more information.<br />
3 – Filters<br />
Now that we have a user administration site with authentication, we need to restrict some pages<br />
on our site to users who have successfully authenticated. We'll do that by using filters.<br />
Filters are functions that can be run before or after routed code. A filter that runs before the<br />
routed code is called a before filter. Similarly well-named is the after filter, which runs after<br />
routed code.<br />
Filters are often used for enforcing authentication. We can create a filter that detects if a user<br />
is not logged in, then redirect him/her to the login form. Actually, we don't need to make this<br />
filter at all. <strong>Laravel</strong> ships with this filter already written. You can find it in your application/<br />
routes.php.<br />
