Could not figure out what your after I think what you are trying to do is something like code below.

Would recommend think about your question first next time.

Just Examples Only

Also check you have set your routes and in form action use

$routes['controller_name'] = "controller_name/index";
$routes['controller_name/add'] = "controller_name/add";
$routes['controller_name/edit/(:any)'] = "controller_name/edit/$1";

Read User Guide. http://localhost/project/something/edit/1 $this->uri->segment(what_your_id_is_in_url);

View Form

action="<?php echo base_url('controller_name/edit' .'/'. $this->uri->segment(3));?>"

Example:

<?php

class Controller_name extends CI_Controller {

public function index() {

  if ($this->uri->segment(3) == TRUE) {
    $this->edit_prop();
  } else {
    $this->add_prop();
  }
}

public function add_prop() { 
}

public function edit_prop(){

$this->load->library('form_validation');

$data['design'] = 'update_property';
$data['title'] = 'Properties Corner!';

$this->form_validation->set_rules('description','Description','required');
$this->form_validation->set_rules('quantity','Quantity','required');
$this->form_validation->set_rules('lifeyears','Life Years','required');
$this->form_validation->set_rules('cost','Cost','required');
$this->form_validation->set_rules('accountable_officer','Accountable Officer','required');

if($this->form_validation->run() == false){

$this->load->view('template_dashboard', $data);

} else {

$this->load->model('model_name');

$id = $this->uri->segment(3); // Read User Guide. http://localhost/project/something/edit/1 $this->uri->segment(what_your_id_is_in_url);

$this->model_name->edit($id);

$this->session->set_flashdata('updated', 'Updated Successfully!');
redirect('properties_controller/view_properties');

}

}

Model

class Model_name extends CI_Model {

public function edit($id) {
    $data = array(
        'id' => $this->input->post('id'),
        'description' => $this->input->post('description'),
        'accountable' => $this->input->post('accountable'),
        'lifeyears' => $this->input->post('lifeyears'),
        'cost' => $this->input->post('cost'),
        'accountable_officer' => $this->input->post('accountable_officer'),
        'quantity' => $this->input->post('quantity')
    );    

    $this->db->where('id', $id);
    $this->db->update('table_name', $data);      

}
}
