Validation Form Edit Codeigniter.

Selamat siang para suhu dan master, Mohon pencerahannya sudah stuck beberapa hari ini, untuk validasi form edit pada codeigniter berikut saya preview tampilan code saya.

Ini file controller dengan methode create() untuk simpan datanya.

	 public function create()
		{
			if (!$_POST){

				$input = (object) $this->electric->getDefaultValues();

			}else{
				$startdate  = $this->input->post('startdate',true);
				$enddate	= $this->input->post('enddate',true);
				$periode	= $startdate .'-'.$enddate;

				$setting 	= $this->input->post('setting',true);
				$fix 		= $this->input->post('fix',true);
				$usages 	= $this->input->post('usages',true);
				$rates 		= $this->input->post('rates',true);
				$basic 		= $this->input->post('basic',true);
				$budget 	= $this->input->post('budget',true);

				$input		= array('periode' => $periode,'setting' => $setting,'fix' => $fix ,
									'usages' => $usages,'rate' => $rates,'basic' => $basic,
									'plan' => $budget,'status' => 'open');

			}


			if(!$this->electric->validate()){
				$halaman		= $this->halaman;
				$main_view		= 'electric/form';
				$form_action	= 'controlelectric/create';


				$dataawal	  	= $this->input->post('startdate',true);
				$dataakhir		= $this->input->post('enddate',true);
				$datasetting	= $this->input->post('setting',true);
				$datafix		= $this->input->post('fix',true);
				$datausages		= $this->input->post('usages',true);
				$datarates		= $this->input->post('rates',true);
				$databasic		= $this->input->post('basic',true);
				$databudget		= $this->input->post('budget',true);


				$this->load->view('template', compact('halaman','main_view','form_action',
														'dataawal','dataakhir','datasetting',
														'datafix','datausages','datarates','databasic','databudget'));

					return;
			}


			if($this->electric->insert($input)){

				$this->session->set_flashdata('success','Data Cost Basic berhasil disimpan.');

			}else{

				$this->session->set_flashdata('error','Data Cost Basic Gagal disimpan.');

			}
			redirect('controlelectric/index');

		}

File controller dengan method edit().

		public function edit($id = null)
		{

			$electric = $this->electric->where('id', $id)->get();

			if (!$electric) {
				$this->session->set_flashdata('warning', 'Data Basic Electric tidak ada.');
				redirect('controlelectric');
			}

			if (!$_POST) {
				$input = (object) $electric;



			} else {
				$input = (object) $this->input->post(null, true);
			}


			if (!$this->electric->validate()) {
				$halaman     = $this->halaman;
				$main_view   = 'electric/form';
				$form_action = "controlelectric/edit/$id";

				$this->load->view('template', compact('halaman', 'main_view', 'form_action', 'input'));
				return;
			}

			if ($this->electric->where('id', $id)->update($input)) {
				$this->session->set_flashdata('success', 'Data Basic Cost berhasil diupdate.');
			} else {
				$this->session->set_flashdata('error', 'Data Basic Cost gagal diupdate.');
			}

			redirect('controlelectric');

		}

Ini form untuk tambah data sekaligus edit.

Bagaimana cara validasinya,saya bingung pada inputan form untuk default value di form_input('name',$value). variable $value harus diisi variable apa ya gan...
