Get method not supported, use post - php

Question

I'm getting the error when I try to create a post and I don't know how to fix it since I just began using laravel and I'm still a noobie.
Route (web.php)
Route::put('/create_action', [App\Http\Controllers\ActionController::class, 'createAction'])->name('auditor.create_action');
This is my controller method:
public function createAction(Request $request) {
$sectors = \DB::table('sector')->get();
$risicosoorten = \DB::table('risicosoort')->get();
$risicoclassificaties = \DB::table('risicoclassificatie')->get();
$users = \DB::table('users')->where('name')->get();
$statussen = \DB::table('status')->get();
return view('auditor.create_action' , [
'sectors' => $sectors,
'risicosoorten' => $risicosoorten,
'risicoclassificaties' => $risicoclassificaties,
'users' => $users,
'statussen' => $statussen
]);
$actie->create([
'create_date' => $req->create_date,
'bron_detail' => $req->bron_detail,
'audit_oordel' => $req->audit_oordel,
'process' => $req->process,
'nummer_bevinding' => $req->nummer_bevinding,
'omschrijving_bevinding' => $req->omschrijving_bevinding,
'probleem' => $req->probleem,
'risico_beschrijving' => $req->risico_beschrijving,
'oorzaak' => $req->oorzaak,
'aanbeveling_ia' => $req->aanbeveling_ia,
'map' => $req->map,
'datum_deadline' => $req->datum_deadline,
'datum_bijgesteld' => $req->datum_bijgesteld,
'datum_gesloten' => $req->datum_gesloten,
'voortgang' => $req->voortgang,
'aantekeningen_ia' => $req->aantekeningen_ia,
'oordeel_ia' => $req->oordeel_ia,
'sector' => $req->sector,
'pr' => $req->pr,
'sr' => $req->sr,
'arc' => $req->arc,
'orc' => $req->orc,
'grc' => $req->grc,
'status' => $req->status,
'sub_status' => $req->sub_status
]);
}
my blade file with the form:
#extends('layouts.master')
#section('title')
#endsection
#section('content')
<div class="create_action" id="post">
<form action="{{ route('auditor.create_action') }}" method="POST">
#method('PUT')
#csrf
<form>
<div class="form-group">
<label for="creation_date">Datum ontstaan actie</label>
<input type="date" class="form-control" name="create_date">
</div>
<div class="form-group">
<label for="bron_detail">Bron detail</label>
<input type="text" class="form-control" name="bron_detail">
</div>
<button type="submit" class="btn btn-primary" name="submitBtn" value="submitPost"><strong>Maak actie aan</strong></button>
#endsection
and wayy more form input fields but trying to keep it as short as possible!

Answer 1

You have two opening form tags in your view. Right after the #csrf directive. Is this intentional? Because you can not nest form tags.
This may be what is causing your error because the application is trying to use the 'Get' method for the inner form tag since no method was stated.
