Laravel Parameter in every url - php

Question

I have read almost everything in web and documentation but i can't find solution for my Problem.
I have a variable stored in Session , then I want to put this variable in every url generated by route('some-route') .
In Session I have sub = "mysubid"
When I generate Route route('my-route') I want to pass this sub parameter in query string: http://domain.dom/my-route-parameter?sub=mysubid
Can you help me to solve This problem? Any helpful answer will be appreciated;

Answer 1

You can use the Default Values feature.
First create a new middleware php artisan make:middleware SetSubIdFromSession. Then do the following:
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\URL;
class SetSubIdFromSession
{
public function handle($request, Closure $next)
{
URL::defaults(['sub' => \Session::get('sub')]);
return $next($request);
}
}
At the end register your new middleware in app/Http/Kernel.php by adding it to $routeMiddleware.
protected $routeMiddleware = [
// other Middlewares
'sessionDefaultValue' => App\Http\Middleware\SetSubIdFromSession::class,
];
Add {sub} and the middleware to your route definition:
Route::get('/{sub}/path', function () {
//
})
->name('my-route')
->middleware('sessionDefaultValue');
Since you want this on every web route you can also add the middleware to the web middleware group:
protected $middlewareGroups = [
'web' => [
// other Middlewares
'sessionDefaultValue',
],
'api' => [
//
]
];

Try this , You need to create middleware php artisan make:middleware SetSubSession
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\URL;
class SetSubsSession
{
public function handle($request, Closure $next)
{
if(session('sub')){
$url = url()->full();
return redirect($url.'?sub='.session('sub'));
}
return $next($request);
}
}
in app/http/Kernel.php
protected $routeMiddleware = [
........
'setsubsession' => \App\Http\Middleware\SetSubsSession::class,
]
in route.php add
Route::group(['middleware' => 'setsubsession'], function(){
//and define all the route you want to add sub parameter
});
using this you don't need to change all your routes.This will automatic add "sub" in the route define in that middleware.
