controller

public function new_inventory(){         $data['item_name']=$this->commissary_model->get_items();          $this->form_validation->set_rules('date_added','date added','required');         $this->form_validation->set_rules('item_name','item name','callback_combo_check');         $this->form_validation->set_rules('quantity','quantity','required');         $this->form_validation->set_rules('amount','amount','required|numeric');         $this->form_validation->set_rules('username','user name');          if($this->form_validation->run()==false){             // $data="";             $this->load->view('new_inventory_view',$data);         }else{             $data=array(                     'date_added'=>@date('y-m-d',@strtotime($this->input->post('date_added'))),                     'item_name'=>$this->input->post('item_name'),                     'quantity'=>$this->input->post('quantity'),                     'amount'=>$this->input->post('amount'),                     'username'=>$this->session->userdata('username')                 );             $this->db->insert('add_inventory',$data);             $this->session->set_flashdata('msg','<div class="alert alert-success text-center">item added inventory.</div>');             redirect('commissary/added_to_inventory');         }     } 

instead of "text value" inside form dropdown, index 1 or 2 or 3 or 4 or 5 etc.... thank you.

that how <select> options work - value of select option returned.

if want text have setup $item_names differently , have index same text. accomplished little restructuring in model.

function get_items() {   $this->db->select('item_name');   $this->db->from('commissary_items');   $query = $this->db->get();   $result = $query->result();    $item_names = array();    foreach($result $item)   {     $item_names[$item->item_name] = $item->item_name;   }    return $item_names; }
