this is the button edit
<button data-toggle="modal" data-target="#editModal-{{ $pelanggan->id }}" class="btn btn-sm btn-primary"><i class="fa fa-edit"></i></button>
this is the modal view
#foreach($daftar_pelanggan as $pelanggan)
<div class="modal fade" id="editModal-{{ $pelanggan->id }}" tabindex="-1" role="dialog" aria-labelledby="editModalLabel" aria-hidden="true">

</div>
#endforeach
this is the route
Route::put('daftar_pelanggan/update/{id}', '\App\Http\Controllers\DaftarPelangganController#update')->name('daftar_pelanggan.update');
and this is the controller
public function update(Request $request, $id)
{
$update_pelanggan = DaftarPelanggan::find($id);
$update_pelanggan->nama_pelanggan = $request->updateNamaPelanggan;
$update_pelanggan->alamat = $request->updateAlamat;
$update_pelanggan->no_telp = $request->updateNoTelp;
$update_pelanggan->poin = $request->updatePoin;
$update_pelanggan->status_member = $request->updateKategori;
$update_pelanggan->save();
if($simpan){
Alert::success(' Berhasil Tambah data ', ' Silahkan dicek kembali');
}else{
Alert::error('data gagal disimpan ', ' Silahkan coba lagi');
}
return redirect()->back();}
what's wrong with this code ?

Answer 1

You have named the select control as status_member in the form while you are using $request->updateKategori in controller method/action while saving update data.
You can cross check by dd($request->all()) as first line of the update method and check which key value pairs are available as request data.
Change the update method like
public function update(Request $request, $id)
{
$update_pelanggan = DaftarPelanggan::findOrFail($id);
$update_pelanggan->nama_pelanggan = $request->updateNamaPelanggan;
$update_pelanggan->alamat = $request->updateAlamat;
$update_pelanggan->no_telp = $request->updateNoTelp;
$update_pelanggan->poin = $request->updatePoin;
//name of key $request->status_member must match name=status_member on select control in the form
$update_pelanggan->status_member = $request->status_member;
$update_pelanggan->save();
//------------- OR you can simply do ---------------------------//
//$update_pelanggam = DaftarPelanggan::findOrFail($id);
//$update_pelaggan->update($request->all();
//-------------------------------------------------------------//
if($simpan){
Alert::success(' Berhasil Tambah data ', ' Silahkan dicek kembali');
}else{
Alert::error('data gagal disimpan ', ' Silahkan coba lagi');
}
return redirect()->back();
}
