$this->data['option_pengujian'][$row->id_penguji] = $row->penguji; this code of function
public function tambah() { $this->data['breadcrumb'] = 'pengujian > tambah'; $this->data['main_view'] = 'view_pengujian/pengujian_form'; $this->data['form_action'] = 'pengujian/tambah'; $penguji = $this->penguji->cari_semua(); if($penguji) { foreach($penguji $row) { $this->data['option_pengujian'][$row->id_penguji] = $row->penguji; } } else { $this->data['option_pengujian']['00'] = '-'; $this->data['pesan'] = 'data penguji tidak tersedia. silahkan isi dahulu data penguji.'; // if submit if($this->input->post('submit')) { if($this->siswa->validasi_tambah()) { if($this->siswa->tambah()) { $this->session->set_flashdata('pesan', ' proses tambah data berhasil'); redirect('pengujian'); } else { $this->data['pesan'] = 'proses tambah data gagal'; $this->load->view('template', $this->data); } } else { $this->load->view('template', $this->data); } } else { $this->load->view('template', $this->data); } } } this cari_semua() in model
public function cari_semua() { return $this->db->order_by('id_penguji', 'asc')->get($this->db_tabel)->result(); }
... foreach($penguji->row() $row){ ... or
... foreach($penguji->result() $row){ ... or : if want return ($penguji) array model, add (->row() or ->result()) @ end of variable you'd return.
if want easier learn, please write script neatly.
here's model
public function cari_semua() { $this->db->order_by('id_penguji', 'asc'); return $this->db->get($this->db_tabel)->result(); // have made result array here. //so, don't need use `->result` in controller. } but, if model function contains errors, never result shows up, there error page instead of it.
