Laravel : CRUD update a form

Question

I will wish in fact to learn to update my data on Laravel. I am able to recuperate the ID with the informations from recording but when I change several elements on my form and that I confirm.

I have a problem concerning Illuminate\\Routing\\RouteCollection methodNotAllowed the error message is Auth::routes(); route::resource('student','AdminController');

My level is yet slow to understand the problem... What should I do ?

For information here is my code

I have a file named AdminController

class AdminController extends Controller
{
    public function index()
    {
      $students = Student::paginate(5);
      return view('student.index', compact('students'))
             ->with('i', (request()->input('page',1)-1)*5);
    }

    public function create()
    {
        return view('student.create');

    }

    public function store(Request $request)
    {
        $request->validate([
                'firstname' => 'required',
                'lastname' => 'required'
        ]);

        Student::create($request->all());
        return redirect()->route('student.index')
                    ->with('success', 'save');
    }

    public function edit($id)
    {
        $student = Student::find($id);
        return view('student.edit', compact('student'));

    }

    public function update(Request $request, $id)
    {
        $request->validate([
                'firstname' => 'required',
                'lastname' => 'required'
        ]);

        $student = Student::find($id);
        $student->firstname = $request->get('firstname');
        $student->lastname = $request->get('lastname');
        $student->save();

        return redirect()->route('student.index')
                  ->with('success', 'updated successfully');

    }

}

In View I have a folder nammed Student with 2 files

index.blade.php

@section('content')
      <div class="px-content">
        <div class="page-header">
            <div class="row">

Concerning the folder route I have that

Auth::routes();
route::resource('student','AdminController');

Do you have an idea please ? Because I don't understand my problem...

Answer 1

在表单内部，添加此行

{{ method_field('PUT') }}

Answer 2

Using a resource for the routes, your update route will have method PUT|PATCH so in order to be able to make a put request in your form inside edit.blade.php you are missing

@method('PUT')

keep in mind that the method tag on your form should remain POST this is an additional field.

And please everyone read some documentation before you answer https://laravel.com/docs/master/routing#form-method-spoofing

Answer 3

in your edit.blade.php file you use POST method for form tag. You should change it to PUT

<form class="panel-body" action="/student/edit/{{$student->id}}" method="POST">

change it to

<form class="panel-body" action="/student/edit/{{$student->id}}" method="PUT">

Because route::resource() generate PUT mathod route for update.

Answer 4

just add the below code in your blade after your <form>

<input name="_method" type="hidden" value="PATCH">

and also change your route with Route::PATCH('/update/{id}','YourController@update');
