i'm new to laravel, just started building my first laravel application (v.5.2). I come from codeigniter. In CI i used to create a pre-controller hook to check login status and set language before any controller loads. Application-wide stuff.
I can't find anything on pre-controller hooks in the laravel docs. There is something called "middleware" however that might do the job. At what point does this Middleware kick in?
Am i on the right track? or is there a better way do these jobs in laravel.
Yes you can do that with middleware.
Middleware will execute before hitting your controller's method.
Though I would suggest you to make a base controller where you can create a method to do this stuff and call that method from the constructor of the base class.
Edit
So I just read that you want to check if the user is logged in. For this purpose you have auth middleware.
Yes, middleware is the best option. I'm using Auth Middleware to implement this kind of feature in my application.
Like below.
public function __construct()
{
$this->middleware('auth' , ['except' => ['show']]);
parent::__construct($this);
}
Here I want to give permission to only show action without login.
You can also use form request to check permission/authentication for each action.
For Laravel 5 # (5.2)
You can have a look on App\Http\Controllers\Controller
Actually all other controllers extends this base controller.
Issue :
1. If routes are not use controller in this case it not works.

I am really struggling with Laravel auth. I read the manual many times, went to the code, but I still don't understand how the level of intrication of the Auth module.
As far as I understood, the app files that take part of the Auth are:
Manager: Auth (Illuminate\Auth\AuthManager)
Service Provider: AuthServiceProvider (Illuinate\Foundation\Support\ProvidersAuthServiceProvider)
Middleware: Authenticate
Gate
Model: User
Controller: LoginController
It seems these controllers LoginController, RegisterController, ... are called by magic, hardcoded deep down in Illuminate\Routing\Router. But, I do not want to use or register any ResetPasswordController, neither ForgotPasswordController simply because I do not hold any passwords on my application.
So in my case I do no store any email or password in my database. My authentication is done with OAuth2, the only think I do, is collecting an access token that I store on my database.
The question is:
How can I use the builtin Laravel Auth system that I am forced to use anyway because some providers require an access to app('auth')?
What then is the best solution in my case?
Rewrite the whole Auth Manager and override the Router to remove the burred links to the unneeded controllers
Tweak the existing Auth system to fulfill my needs
I am quite lost...
I've Blog website where all user can post Blog.I have learned about Gates,Policy and Middleware .Please come to know that i am using Auth() Default Authentication Process in Laravel. I want to protect user (A) blog from other users.
Now I have many things to handle this.
Using Auth if(Auth()->user->id==$blog->user_id)
Using Gate if(Gate::Allow('blog_protection',$blog))
Using Policy if(Auth::user()->cant('blog_protection',$post))
Using Middleware $this->middleware('blog_access')
Please tell if i am wrong Meaning of that functions then what is best method to handle this request for more reusable . Many Thanks In Advance.
I would consider writing a policy class for blog model resource. Multiple reasons :
You can list all access methods related to blog in one file to easy to track
You can do just $this->authorize('access_method_name', Blog::class) in controller
You can pass extra arguments to the method to filter it conditionally
If you have a method outside controller and you need to add filter(ideally the controller authorize() would filter it out) but still you can use
$user->can() or $user->cant()..
which will internally use the same policy.
Also to mention you can use this in blade directives #can()...# endcan #cannot...#endcannot
Middleware is something which would intervene in every request specified in the route group or all requests if its registered as global middleware group. If you want an access filter applicable globally in all routes then middleware is a better option. But for specific resource, I would prefer policies.
In short middleware for request filtering and handling whereas Policy for managing granular level access controls.
I am new in laravel and I have one problem with middleware. On official laravel site, I found code for creating controller.
When I creating controller it is recommended to add middleware in constructor or this is only if I need some additional functionalities?
Also, if I include auth middleware, did I get some benefits by default, like security checks or similar or I must to rewrite middleware code first?
class UserController extends Controller {
/**
* Instantiate a new controller instance.
*
* #return void
*/
public function __construct() {
**//this part includes some protection or similar by default ?**
$this->middleware('auth');
}
}
Middleware is used when you want to filter the HTTP requests entering your application.
For example, including the built-in auth middleware will restrict non-authenticated users from accessing a page and redirect them to the login screen.
You can include middleware into your controller and routes.
In the controller you do it like so:
public function __construct()
{
$this->middleware('auth');
}
For a route you do this:
Route::get('/page', 'MyController#myMethod')->middleware('auth');
Do I need to include this part of code when I creating controller or not ?
As I said in my comment, it really depends on the desired functionality whether you use it or not.
An example
Your homepage should probably be accessible for anyone who visits you website, while your dashboard should only be displayed to authenticated users.
That's where you would include the auth middleware.
Question #1
Do you need to use $this->middleware('auth'); in your controller?
Answer: Only if you want to protect all of the methods of that controller from non-authenticated users and only allow signed in users to access controller actions.
Question #2
Do you get benefits for using the auth middleware?
Answer: Yes you do, only authenticated users can access the controller or routes protected by auth.
** Question #3**
Do you need to write your own middleware?
Answer: Only if you need to override a middleware or need extra functionality that is not already provided (php artisan make:auth), but if you are rolling your own login functionality then you will likely need/want to create your own middleware.
Resources:
Look in App\Http\Kernel.php and you will see that the $routeMiddleware array matches the auth middleware to the \Illuminate\Auth\Middleware\Authenticate::class which actually verifies that the current user is logged in and allows them to pass, if they are not logged in then it will redirect them to the '/login' route.
You will see that Laravel uses quite a bit of middleware by default, such as starting the session, encrypting cookies and protecting against CSRF forgery.
There are several ways to implement middleware, which I'm sure you saw in the docs.
Some Helpful Video Tutorials:
I suggest you watch each of the free series usually titled Laravel from Scratch on Laracasts.com. I would also suggest watching all of from Laravel 5.7 back to 5.1 or 5.0 as Jeffrey Way may use different techniques in similar situations and it will provide you with a great tips and helpful information as to how things work along with some Laravel best practices along the way. I've subscribed to him for years and work in Laravel everyday and I still learn some new things from watching his videos, a subscription is easily worth 10-20 what he charges.
I am using Laravel 5.3 and am having some issues with the authentication.
Prior to me working on this program the developer set it up so all of the controllers that need to authenticated are extended from an account controller class (which extends the base controller etc). The account controller class just runs $this->middleware('auth') which should run the handle method in the authenticate class to check if there is an active session and if not redirect the user to the login page.
The strange thing is that this works for some controllers but not for others even though the controllers are all extended from the same account controller. In the controllers it is not working, it does not seem to even get to the handle method in the authenticate class.
I was wondering if there is something in laravel that specifies what routes to authenticate and i need to define in there or does anyone have any other idea of why this seems to work for some pages and not others even though the controllers are setup the same?
You can put a check at Route level like:
Route::group(['middleware' => 'auth'], function () {
// All the routes enclosed in this block are protected
});
// Put unprotected routes outside the block
SO community!
I have a project, that I've built on Laravel 5.2. As its authorization I am using the built in one, that can be generated by running
php artisan make:auth
It serves well, but the system's users will be mostly invited by the administrator, whose account is created by the built-in auth action under the route /register. There will be multiple instances of my project hosted separately.
Once the system is set up I do need the route to create the administrator account, but after that I would like the route to be not be accessible.
The customization I need is as follows:
I am thinking about an "if" that would check how many administrator accounts there currently are. If there is at least one, the /register route would redirect to /login.
Something like this:
$administrators = User::where( 'role', User::ROLE_ADMIN )->get();
if ( count( $administrators ) != 0 ) return redirect( url('/login') );
It is a simple piece of code, but I do not know where to put it.
First possible solution:
At first I was thinking that I would need to customize the register action by adding the check to it, but the AuthController does not have register action and I do not understand how the AuthController works.
Second possible solution:
I was thinking of creating a middleware with the admin count check for the /register route, but in the routes file the built-in authorization routes are somehow condensed and added with this piece of code:
Route::auth();
Is there some way of extracting the /register route out of that, so I bind the middleware on to it?
Or maybe there is a better way of adding the check.
Any help will be much appreciated!
