Passing parameters to middleware in Laravel

Question

Let's say I have a route pointing to middleware;

Route::get("/user/{id}", ['middleware' => 'auth', function ($id) {  }]); 

And my middleware code is as follows:

public function handle($request, Closure $next) {     return $next($request); } 

If I want to use $id in the middleware, how do I do that?

Answer 1

In you case you cannot pass $id into the middleware.

Generally you can pass parameters to middleware via using : symbol like this:

Route::get('user/{id}', ['middleware' => 'auth:owner', function ($id) {     // Your logic here... }]); 

And get the passed parameter into middleware method like this:

<?php  namespace App\Http\Middleware;  use Closure;  class Authentication {     public function handle($request, Closure $next, $role)     {         if (auth()->check() && auth()->user()->hasRole($role)) {             return $next($request);         }          return redirect('login');     } } 

Note that the handle() method, which usually only takes a $request and a $next closure, has a third parameter, which is our middleware parameter.

If you passed in multiple parameters like auth:owner,subscription to your middleware call in the route definition, just add more parameters to your handle method which will look like this - handle($request, Closure $next, $role,$subscription)

Answer 2

You can use one of the following method to access the route parameter in a middleware:

First Method

$request->route()->parameters();

This method will return an array of all the parameters.

Second Method

$request->route('parameter_name');

Here parameter_name refers to what you called the parameter in the route.
