How to insert data to database with Laravel - php

Question

I'm trying to insert my data to database from form.
My URL to create the data is web.com/siswa/create
But when I click submit system show error MethodNotAllowedHttpException.
How I can fix it? Is there anything wrong with my code?
Here is my form:
<form action="{{ url('siswa') }}" method="POST">
<div class="form-group">
<label for="exampleInputEmail1">NISN</label>
<input type="text" class="form-control" name="nisn" id="nisn" placeholder="NISN"></div>
<div class="form-group">
<label for="exampleInputEmail1">Nama Siswa</label>
<input type="text" class="form-control" name="nama_siswa" id="nama_siswa" placeholder="Nama Siswa"> </div>
<button type="submit" class="btn btn-success btn-sm font-weight-bold">Submit</button></form>
Controller:
public function tambah()
{
return view('siswa.create');
}
public function store(Request $request)
{
$siswa = new \App\Siswa;
$siswa->nisn = $request->nisn;
$siswa->nama_siswa = $request->nama_siswa;
$siswa->tanggal_lahir = $request->tanggal_lahir;
$siswa->jenis_kelamin = $request->jenis_kelamin;
$siswa->save();
return redirect('siswa');
}
Route:
Route::get('/siswa/create', [
'uses' => 'SiswaController#tambah',
'as' => 'tambah_siswa'
]);
Route::get('/siswa', [
'uses' => 'SiswaController#store',
'as' => 'simpan_siswa'
]);

Answer 1

change your store function route from get to post
Route::post('/siswa', [
'uses' => 'SiswaController#store',
'as' => 'simpan_siswa'
]);
Use Csrf protection field in your form for the session timeout error
{{ csrf_field() }}
OR
<input type="hidden" name="_token" id="csrf-token" value="{{ Session::token() }}" />
OR if you are using Form builder
{!! Form::token() !!}

Answer 2

In Route please use post instead of get
Route::post('/siswa','SiswaController#store');
and also include {{ csrf_field() }} in form

Answer 3

you are using method="POST" on your form but in on your route you are using Route::get
Use Route::post for your route

Answer 4

In your form you've given POST method, but your router doesn't have any POST handler. So all you have to do is , when you are trying to store data from form to DB you have to post the data, and the router should handle it.
Try this
Route::post('/siswa', [
'uses' => 'SiswaController#store',
'as' => 'simpan_siswa'
]);

Answer 5

You are using POST method in your form and using GET in route.
try this
Route::post( '/siswa', [
'uses' => 'SiswaController#store',
'as' => 'simpan_siswa'
] );
