Showing subpages based on a session in Laravel 5.8 - php

I am begginer in Laravel. I am use Laravel 5.8 in my project.
I need to do something so that a specific route can be viewed by a user with a php adult = 1 session.
I have route:
Route::get('/', 'FrontendController#index')->name('index');
Route::get('/sample1', 'FrontendController#sample1')->name('sample1');
The SAMPLE1 view is for users with php adult = 1 session.
If the user does not have such a session - it must be automatically redirected to # index
How can you do this?

You can achieve this by creating a custom middleware, take a look at the documentation here:
https://laravel.com/docs/5.8/middleware
Instead of using session, you can maintain a user is adult or not on the users table, which means you can access this info via authenticated user (which is available throughout the whole app).
For e.g. in your app, use php artisan make:auth and this will scaffold out everything you need to for a register/login system. Before you run the migration, add a new field to the create_users_table migration, e.g. $table->boolean('adult')->default(false);
Then once the migration is ran, you can create a new middleware using: php artisan make:middleware CheckAdult with something like this:
<?php
namespace App\Http\Middleware;
use Closure;
class CheckAdult
{
public function handle($request, Closure $next)
{
if (!auth()->check() || !auth()->user()->adult) {
return redirect('/');
}
return $next($request);
}
}
The above middleware will redirect anyone who is not logged in or have adult = 0 back to index page, otherwise continue with their request.
Then register the middleware and use it in the routes; as per the documentation.

you can use auth and middleware to achieve this. the simple logic would be something like this: $id = Auth::user()->adult; in your controller to check for users. ofcorse adult is a field in your table.
//on top of your controller place this
public function __construct()
{
$this->middleware('auth');
}
//control logic to check user
if($adult==1){
//perform unique task
}else{
return redirect('/')->with('message','You are not permitted')
}

Laravel: Check if User is an admin using isAdmin column?

I'm really new to laravel and have been reading the documentations and tutorials. I'm planning on making an app that has 2 roles, admin and user. I modified my User model to have the column 'isAdmin' with boolean value since I only need 2 roles. How do I perform a check on this attribute during auth? Thank you.
TO answer your question, first of all to make protect any route using the auth middleware which ensures a user is authenticated (logged in) before they can access the route, you simply need to add the auth middleware.
e.g
web.php
<?php
Route::middleware('auth')->group(function(){
//All Routes which needs user to be logged in
});
or
//Individiual Route Middleware
Route::get('/path/to', 'controller#instance')->middleware('auth');
As for checking user role, you can basically create a middleware for this using the following steps:
run your php artisan make:middleware IsAdminMiddleware
open your IsAdminMiddleware and add this code inside the handle function:
public function handle($request, Closure $next)
{
if(!Auth::check()){
return redirect()->route('login');
}
if(Auth::user()->isAdmin == true){
return $next($request);
}
return redirect()->back()->with('unauthorised', 'You are
unauthorised to access this page');
}

how can I dynamically take users to certain routes based on the service they registered for in Laravel 6

I have three services, Tickets, Cards and Certificates, all in services table. the table columns looks like this:\
user_id, Service, amount_paid, created_at, created_by, transaction_id
this is my route:
Route::get('print/enumeration/{id}', 'TransactionController#printEnumeration');
I want the user to be taken to a separate page based on the service selected. I know i can use middlewares but I dont have a great knowlegde on how to implement it, any help will be greatly appreciated, Thanks.
First create middleware using
php artisan make:middleware midlewareName
Register middleware app/Http/Kernel.php
protected $routeMiddleware = [
'name' => \App\Http\Middleware\name::class,
];
now define your middleware app/Http/Middleware
example
public function handle($request, Closure $next)
{
if (Auth::check() && Auth::user()->isRole()=="admin") {
// Redirect...
return $next($request);
}
return redirect('login');
}
read docs for more details https://laravel.com/docs/6.x/middleware
first, create your middleware by running:
php artisan make:middleware ServiceMiddleWare
now open the file created in app/Http/Middleware directory. inside handle method you can place a switch statement and set a case per service and define redirects.
do not forget to register your middleware in kernel. take a look at this document

How is Localization in Laravel implemented?

I want to implement localization on my website using Laravel 5.5.
However, I am not sure what the standard practice when using localization should be. I have used the LocalizationController module from the Laravel documentation. My goal is to have the localization option selected via a dropdown. Then the user's selection should be remember.
Do I store their selection in a database for future use?
Or, is this something to keep in a cookie?
Side note:
(I want to avoid having their selection in the url. I'll either pass the data in a request or get method.)
For registered and logged-in users i recommend to store the users language in the database. Everytime a user logs in the application should set the language for the current user. Maybe you take a closer look on middleware. Build a language middleware, register it as new middlewaregroup and assign it to every route (-group) you need. A middleware could look like this:
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
class LanguageMiddleware
{
public function handle($request, Closure $next)
{
if(Auth::check()){
// user is logged in
App::setLocale(Auth::user()->language);
return $next($request);
}
App::setLocale(config('app.locale'));
return $next($request);
}
}
Now register the new middleware in app/Http/Kernel.php as new middleware-group under protected $middlwareGroups:
// other middleware-groups
'language' => [
\App\Http\Middleware\LanguageMiddleware::class
]
Finally assign middelware-group to route (-group):
Route::group(['middleware' => ['language']], function(){
// Routes...
});
Unfortunately there is no build-in function to show a dropdown-language-select. But you can simply build a blade-partial which you can integrate in your navbar or where-ever you want to show/use it. You could ask new users during registration for their preferred language.
Guests/unregistered users could use the dropdown. By default they should see the default language.
Hopefully this helps you.

modify Laravel Auth registration page

I am trying to modify the Laravel Auth registration system in that I'd like to require that a token parameter be provided in order for the user to be able to access the registration page (ie http://website.dev/register/{tokenhere}). Below is the pertinent code:
From my routes\web.php file:
Route::get('/register/{token}', function() {
//
})->middleware('token');
From my \App\Http\Middleware\CheckToken.php file:
<?php
namespace App\Http\Middleware;
use Closure;
class CheckToken
{
public function handle($request, Closure $next)
{
if($request->token != 'test') { #just hard coding something here for testing purposes
return redirect('home');
}
return $next($request);
}
}
I also added 'token' => \App\Http\Middleware\CheckToken::class to the $routeMiddleware array in \App\Http\Kernel.php
However, I go to http://website.dev/register and I'm able to access the page, despite not providing a token parameter. I can also see that if I provide the 'test' parameter that the middleware is looking for (http://website.dev/register/test), I get a blank page.
Hoping someone can point me in the right direction. I'm quite new to MVC and Laravel. Thanks for your time!
You can just create custom route, like /register/{token} and handle this token in the controller. Maybe even set in middleware group if you want.

How can we redirect a page to another if a session is not found using route in Laravel 5.3

I am using a session separately other than the default authentication sessions. If an user try to access my secured page, he should have the session set. If anyone without that session try to access means, they will be redirected to error page. I am using Laravel 5.3
The user can view the below two pages only if the session variable named 'secured_user' is set. Otherwise they will be redirect to the error page
Route::get('/secured-page1', 'ValidationController#CheckSecuredLogin_1');
Route::get('/secured-page2', 'ValidationController#CheckSecuredLogin_2');
The best option would be a policy.
You can create certain constrains and couple it with your models. Policies are especially suitable for changing your logic later on.
See here: Create Policy
Within you PagesPolicy, you can add this function:
public function before(User $user, $ability)
{
if ($user->isSuperAdmin()) {
return true;
}
}
public function seeSecurePage(User $user)
{
// Your custom Code and session handling
if(session("secured_user")) return true;
return false;
}
and in your controller.
$user->can("seeSecurePage","Pages");
If "can" fails, it will automatically redirect to error 403.
P.S.: Another possibility are Gates
You should use Laravel Middlewares to achieve this, I think middlewares are made for the work you need:
First create a new middleware by running the artisan command:
php artisan make:middleware CheckSesison
Then the CheckSession would look like this:
<?php
namespace App\Http\Middleware;
use Closure;
class CheckSession
{
public function handle($request, Closure $next)
{
if ($session_value != 'YOUR_DESIRED_VALUE') {
return redirect('home');
}
return $next($request);
}
}
Now in your routes file you can use laravel's route middleware() method to implement it like this:
Route::get('/secured-page1', 'ValidationController#CheckSecuredLogin_1')
->middleware(CheckSession::class);
Hope this helps!
In addition to the awnser above, you could also use middleware that's used on the routes and even group them if required. It is a simple, quick and clean solution. Inside the middelware you simple check if the session you require is there and depending on the result you take any action necessary.
