Laravel - The POST method is not supported for this route. Supported methods: GET, HEAD

Question

I am trying to add an event on a calendar I have created, however I am getting the following error

The POST method is not supported for this route. Supported methods: GET, HEAD

I have used the methods @csrf and {{ method_field('PUT') }} to no avail. I have also cleared route cache which did not help. Any help is much appreciated.

Routes:

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::namespace('Admin')->prefix('admin')->name('admin.')->group(function(){
    Route::middleware('can:manage-users')->group(function(){
        Route::resource('/users', 'UsersController', ['except' => ['show']]);
        Route::resource('/courses', 'CoursesController', ['except' => ['show']]);
    });
    Route::middleware('can:manage-calendar')->group(function(){
        Route::get('events', 'EventsController@index')->name('events.index');
        Route::post('/addEvents', 'EventsController@addEvent')->name('events.add');
    });
})

index.blade.php

@extends('layouts.app')
@section ('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-14">
                <div class="card">
                        <div class="card-header">Calendar</div>
                        <div class="card-body">
                        {!! Form::open(array('route' => 'admin.events.index', 'method' => 'POST', 'files' => 'true'))!!}
                            {{-- {{method_field('PUT') }}  
                             @csrf  --}}
                        <div class="row">
                            <div class="col-xs-12 col-sm-12 col-md-12"></div>
                            <div class="col-xs-4 col-sm-4 col-md-4">
                            <div class="form-group">
                            {!! Form::label('event_name', 'Event Name:') !!}
                                <div class="">
                                    {!! Form::text('event_name', null, ['class' => 'form-control']) !!}
                                    {!! $errors->first('event_name', '<p class="alert alert-danger">:message</p>') !!}
                                </div>

The error actually explains the problem. The method POST is not supported for the route you're using. You are trying to post to the route: admin.events.index but you actually want to post to the route events.add.

Route::post('/addEvents', 'EventsController@addEvent')->name('events.add');

  {!! Form::open(array('route' => 'admin.events.add', 'method' => 'POST', 'files' => 'true'))!!}

                            {{-- @csrf  --}}

Adding to this awnser is a possible solution for the validator exception the OP has mentioned in the comments.

The validator not found error can possibly come from the following:

When adding the the following code:

    public function addEvent(Request $request) 
{ 
$validator = Validator::make($request->all(), 
[ 'event_name' => 'required', 
'start_date' => 'required', 
'end_date' => 'required' ]); 

if ($validator->fails()) 
{ \Session::flash('warning', 'Please enter the valid details'); return Redirect::to('admin.events.index')->withInput()->withErrors($validator);

Try adding:

use Illuminate\Support\Facades\Validator;

Hi, thanks for you reply I have added "use Illuminate\Support\Facades\Validator;" to my EventsController but I am still getting the error '404 Not Found' when the 'addEvent' attempts to redirect to 'admin.events.index'.. I am a bit baffled as this route does exist? I appreciate your help. Thanks. – Zak Feb 21 '20 at 13:22
can you do php artisan route:list, Does the route show up? – Collin Feb 21 '20 at 13:40
Managed to fix the redirect issue, I trialled a few different methods of redirecting a route and this worked - return redirect()->route('admin.events.index'); ..as opposed to return Redirect::to('admin.events.index'); which did not work and returned 'not found'... i was unaware there was multiple ways to route .. anyway its all a learning curve.. thank you again for your help - much appreciated. – Zak Feb 21 '20 at 19:31

Just check your form action url route. You have to pass 'route('admin.events.add)' rather than 'route('admin.events.index')' and also dont use 'PUT' it will accept 'POST' as well.

Hi, thank you for your response.. i made your change as suggested however another error appeared in my EventsController - 'validator class not found'.. i proceeded to add this and that is fine. I wonder if you would be able to help further.. the redirect i am returning within the validator is now appearing as '404 not found', I'm not sure what I'm doing wrong.. I am trying to redirect to the 'admin.events.index' when an event is added successfully.. I will paste my code below. I appreciate your help. – Zak Feb 21 '20 at 11:44
EventsController: public function addEvent(Request $request) { $validator = Validator::make($request->all(), [ 'event_name' => 'required', 'start_date' => 'required', 'end_date' => 'required' ]); if ($validator->fails()) { \Session::flash('warning', 'Please enter the valid details'); return Redirect::to('admin.events.index')->withInput()->withErrors($validator); – Zak Feb 21 '20 at 11:44
@KerryMckinney Check my awnser, i will add a possible solution for the validator exception – Collin Feb 21 '20 at 13:07
