return view('tampil',$data);
}

$validation = \Config\Services::validation();
$validation->setRules([
'username' => 'required|string',
'password' => 'required|string',
'email' => 'required|valid_email'
]);
$res = $validation->withRequest($this->request)->run();
if(!$res){
$data['title'] = "Validasi Input";
echo view('crud',$data, [
'validation' => $validation
]);
}
else{
$crudModel = new \App\Models\CrudModel();
$session = \Config\Services::session();
try{
$crudModel->insert($data);
$session->setFlashdata('msg', 'Record Inserted successfully');
}
catch(\Exception $e){
$session->setFlashdata('msg', 'Something went wrong');
}
$data['title'] = "Form Tambah";
echo view('crud',$data);

public function view_edit($id = null)
{
$model = new CrudModel();
$data['user'] = $model->where('id', $id)->first();
return view('update', $data);
