Is it possible to do dependency injection in a controller with a condition?

Question

Laravel

Good day, toaster! Is it possible somehow in the controller to perform dependency injection with a condition? Those. it's about this:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;

class UserController extends Controller
{
    public function update(Request $request, User $user)
    {
        //
    }
}

I'm interested in the option with dependency injection, and not this one:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;

class UserController extends Controller
{
    public function update(Request $request, $user)
    {
        if(!$user = User::where('age', '>', 20)->find($user))
        {
            abort(404);
        }
    }
}

Thank you in advance!

Answer 1

It is not very clear what the conditions depend on, but there are at least two options: one , two .

Answer 2

If you use binding to routing, then this is a good option .
