class Crud extends BaseController

{

public function __construct(){

}

public function index()

{

$data['title'] = "Form Tambah";

$model = new CrudModel();

$data['posts'] = $model->findAll();

return view('tampil',$data);

}

public function create()

{

return view('crud');

}




public function save(){

$data = $this->request->getVar();

$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);

}

public function update($id = null){

$data = $this->request->getVar();

$id = $this->request->getVar('id');

$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'] = "Crud Codeigniter";

echo view('update',$data, [

'validation' => $validation

]);

}

else{

//$CrudModel = new \App\Models\CrudModel();

$session = \Config\Services::session();

try{

$model = new CrudModel();

$user = $model->update($id,$data);

$session->setFlashdata('msg', 'Record Updated successfully');

}

catch(\Exception $e){

$session->setFlashdata('msg', 'Something went wrong');

}

$data['title'] = "Crud Codeigniter";

return redirect()->to( base_url('index.php/crud') );

}

}

}
