Question

I will get MethodNotAllowedHttpException when submitting a form in laravel

Html file

<form method="POST" action="/cards/{{$card->id}}/notes">
    <input name="_token" type="hidden" value="{{ csrf_token() }}"/>
    <textarea name="body" class="form-control"></textarea>
    <button type="submit">Add Note</button>
</form>

routes.php

Route::post('cards/{card}/notes','NotesController@store');

NotesController.php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;

class NotesController extends Controller
{
    public function store()
    {
        return request()->all();
    }
}

Answer 1

Make sure you don't have a route, say a Route::post with a parameter that lies in front of the route you are trying to hit.

For example:

Route::post('{something}', 'SomethingController@index');
Route::post('cards/{card}/notes', 'NotesController@store');

In this case, no matter what you try to send to the cards route, it will always hit the something route because {something} is intercepting cards as a valid parameter and triggers the SomethingController . Put the something route below the cards route and it should work.

Answer 2

MethodNotAllowedHttpException is thrown when no matching route (method and URI) was found, but a route with a matching URI but not matching method was found.

In your case, I guess the issue is because URI parameters differ between the route and the controller.

Here are two alternatives you can try:

1. Remove the parameter from your route:

Route::post('cards/notes','NotesController@store');

2. Add the parameter to your controller:

public function store($card)
    {
        return request()->all();
    }

I have tried to solve this error in lumen and it took me quite a lot of time to figure out the problem. The problem is with laravel itself.

Sometimes if you have another route like GET device/{variable}, laravel stops in this first route...

So what you need to do is change the route POST device to POST device/add
