Laravel - controller doesn't see image input - php

Question

My form:
<form action="{{route('settings.update')}}" method="POST">
#csrf
<div class="col-sm-3">
<div class="form-group">
<label for="avatar">Upload a new one:</label>
<input type="file" id="pic" name="pic"/>
</div>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary">Upload avatar</button>
</div>
</form>
My Controller:
public function update_settings($request)
{
$this->validate($request, [
'pic' => 'required|image'
]);
$path = $request->image->store('/img/');
Auth::user()->image = $path;
return view('pages.settings');
}
The error:
Too few arguments to function App\Http\Controllers\PagesController::update_settings(), 0 passed and exactly 1 expected
I am passing only the image file in the $request, but for some reason the controller doesn't see it, what am I doing incorrectly?

Answer 1

To obtain an instance of the current HTTP request via dependency injection, you should type-hint the Illuminate\Http\Request class on your controller constructor or method. The current request instance will automatically be injected by the service container:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Routing\Controller;
class UserController extends Controller
{
/**
* Store a new user.
*
* #param Request $request
* #return Response
*/
public function store(Request $request)
{
$name = $request->input('name');
//
}
}
Look well that in the method I am injecting the dependence of Illuminate\Http\Request

You need to add enctype='multipart/form-data' to your opening form tag
<form action="{{route('settings.update')}}" method="POST" enctype="multipart/form-data">
