Laravel - Method Illuminate\Http\Request::request does not exist - php

Question

I have created a view to create new courses 'create.blade.php'. And I am trying to store this data in the DB however I am getting the following error:
BadMethodCallException Method Illuminate\Http\Request::request does
not exist.
I am not sure what is causing the error as I have referred to the the request namespace in my controller. See below;
CoursesController.php;
<?php
namespace App\Http\Controllers\Admin;
use Gate;
use App\User;
use App\Course;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;
class CoursesController extends Controller
{
public function __construct()
{
//calling auth middleware to check whether user is logged in, if no logged in user they will be redirected to login page
$this->middleware('auth');
}
public function index()
{
if(Gate::denies('manage_courses')){
return redirect(route('home'));
}
$courses = Course::all();
return view('admin.course.index')->with('course', $courses); //pass data down to view
}
public function create()
{
if(Gate::denies('create_courses')){
return redirect(route('home'));
}
$courses = Course::all()->pluck('title');
$instructors = User::all()->pluck('name', 'id'); //defining instructor variable
return view('admin.course.create', compact('instructors')); //passing instructor to view
}
public function store(Request $request)
{
$course = Course::create($request->all()); //request all the data fields to store in DB
$course->courses()->sync($request->request('courses', [])); //
if($course->save()){
$request->session()->flash('success', 'The course ' . $course->title . ' has been created successfully.');
}else{
$request->session()->flash('error', 'There was an error creating the course');
}
return redirect()->route ('admin.courses.index');
}
}
Create.blade.php
#extends('layouts.app')
#section('content')
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Create Course</div>
<div class="card-body">
<form method="POST" action="{{ route('admin.courses.store') }}" enctype="multipart/form-data">

<input class="form-control {{ $errors->has('title') ? 'is-invalid' : '' }}" type="text" name="title" id="id" value="{{ old('title', '') }}" required>
#if($errors->has('name'))
<div class="invalid-feedback">
{{ $errors->first('name') }}
</div>
#endif
</div>
<div class="form-group">
#if (Auth::user()->isAdmin())
{!! Form::label('Instructor', 'Instructor', ['class' => 'control-label']) !!}
{!! Form::select('Instructor[]', $instructors, Input::get('Instructor'), ['class' => 'form-control select2', 'multiple' => 'multiple']) !!}
#if($errors->has('Instructor'))
{{ $errors->first('Instructor') }}
</p>
#endif
</div>
<div class="form-group">
<button class="btn btn-danger" type="submit">
Save
</button>
</div>
</div>
#endif
</form>
</div>
</div>
#endsection
I am new to laravel so i would appreciate any help. Thanks.

Answer 1

The error message
BadMethodCallException Method Illuminate\Http\Request::request does
not exist
speaks to an attempt to call a method/function named request on the Illuminate\Http\Request class, and that function not existing.
it looks like you are indeed trying to use a request() method here:
$course->courses()->sync($request->request('courses', []));
You most likely want the input() method instead, which would get data posted as 'courses'.
$course->courses()->sync($request->input('courses', []));
as described at https://laravel.com/docs/master/requests#input-trimming-and-normalization
I hope this helps!

Answer 2

change
$course->courses()->sync($request->input('courses', []));
