Laravel Parameter in every url

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;

I know I cann pass parameter like: `route('my-route', ['sub' => \Session::get('sub') ])` but I have too much route in my views to refactor this and I want to make it auto — Malkhazi Dartsmelidze, Jan 09 '19 at 10:46
Why would you do that? You already have that data stored in session. — Cid, Jan 09 '19 at 10:47
To be clear: you want all routes to have the same parameter _always_? — JustCarty, Jan 09 '19 at 10:48
@JustCarty That's Right. I have parameter in Session and want to pass it in every Route. — Malkhazi Dartsmelidze, Jan 09 '19 at 10:51
I think it would make more sense to nest all your routes in a single middleware group and handle what ever you are doing with that session in there. OR use the session data in the controller as adding to the route gains no benefit with it already being stored somewhere, you are just exposing it to the user. — Petay87, Jan 09 '19 at 10:54
@MalkhaziDartsmelidze more often than not, this can be done in the background, are you sure it needs to be passed through the URL? — Script47, Jan 09 '19 at 10:54
*"User must See this parameter In Url"* Is that another great idea from a non-technical manager or is there a reason for that ? Lambda users don't care about variables in URL — Cid, Jan 09 '19 at 10:56
Yes, There Is Reason for that and also great idea by manager :D — Malkhazi Dartsmelidze, Jan 09 '19 at 11:04
Why not create a helper function that will wrap the `route()` method, and accomplish it. This means you will replace the call to `route()` with your function, for example, `customRoute()`? — Oluwatobi Samuel Omisakin, Jan 09 '19 at 11:17
@MalkhaziDartsmelidze Just a note, I updated your tags a little bit to show Laravel 5.7. — Oluwatobi Samuel Omisakin, Jan 09 '19 at 14:50

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' => [
        //
    ] 
];

Great Idea, but I can't pass parameter with Query string with this code – Malkhazi Dartsmelidze Jan 09 '19 at 11:03
I don't get an error but it does not appends query on url – Malkhazi Dartsmelidze Jan 09 '19 at 11:53

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.

Please consider the performance consequences of this approach. First, this will likely result in an infinite loop, it does not check if `sub` is already set in the request, so it will attempt to redirect again. Then, if you solve that issue, every link will still end up with 2 requests: the initial request without `sub`, then the redirected request. — Adrian Gonzales, Apr 27 '21 at 16:14
