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

Question

I have a problem with my edit page. When I submit I get this error:

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

I have no clue where it comes from as I am pretty new to Laravel.

routes(web.php):

Route::group(['middleware' => 'auth'], function () {
Route::get('/', 'ProjectController@index');

Route::get('/projects/{id}', 'ProjectController@show');
Route::post('/create','ProjectController@store');
Route::get('/create', 'ProjectController@create');
Route::get('/projects/{id}/delete', 'ProjectController@destroy');
Route::put('/edit','ProjectController@update');
Route::get('/projects/{id}/edit', 'ProjectController@edit');

});

Controller:

 public function edit($id)
    {
        return view('project.edit',[

            'project' => Project::find($id)
        ]);
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request)
    {
        $project = Project::find($request->id);
        $project->project_name = $request->input('project_name');
        $project->client = $request->input('client');
        $project->description = $request->input('description');
        $project->time_span = $request->input('time_span');
        $project->text_report = $request->input('text_report');
        $project->created_by = $request->input('created_by');

        $project->save();

        return  redirect('/')->with('success', 'Project aangepast');
    }

Answer 1

There are multiple ways you can handle this:

1. If you insist on using PUT you can change the form action to POST and add a hidden method_field that has a value PUTand a hidden csrf field (if you are using blade then you just need to add @csrf_field and {{ method_field('PUT') }}). This way the form would accept the request.

2. You can simply change the route and form method to POST. It will work just fine since you are the one defining the route and not using the resource group.

Answer 2

I know this is not the solution to OPs post. However, this post is the first one indexed by Google when I searched for answers to this error. For this reason I feel this will benefit others.

The following error...

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

was caused by not clearing the routing cache

php artisan route:cache

Answer 3

add @method('PUT') on the form

exp:

<form action="..." method="POST">

@csrf  

@method('PUT')



</form>
