set values after form submit

Question

I am using codeigniter and have a form for add transfers. I have written validation rules in the controller but when the form submitted the errors message appear but the form forget the values which was entered by the user.

I try to use set_value and it works but sometimes I want to make if statements and I think it mus be in the controller not in the view. Is there a way to make the set value in the controller and return it in $data to the view

view

<?php $type_val= set_value('type');  ?>
<select class="form-control show-tick" id="type" name="type">
    <option value="<?=set_value('type');?>" ><?=($type_val == 1) ? 'Exit' : 'Come';?></option>
    <option value="1">Exit</option>
    <option value="2">COME</option>                         
 </select>

controller

public function add(){

if($this->input->post('submit')){

$rules = $this->get_rules_validation();
$this->form_validation->set_rules($rules);

        if ($this->form_validation->run() == FALSE) {
            $data['title'] = 'Add Transfer';
            $data['view'] = 'admin/transfer/transfer_add';
            $data['validation_error'] = true;
            $this->load->view('layout', $data);
        }
        else{
            $data = array(
                'type' => $this->input->post('type'),

            );
            $data = $this->security->xss_clean($data);
            $result = $this->transfer_model->add_transfer($data);
            if($result){
                $this->session->set_flashdata('msg', 'Transfer is Added Successfully!');
                redirect(base_url('admin/transfer'));                   
            }
            else{
            $this->session->set_flashdata('msg', 'Transfer Cant Be added!');
            redirect(base_url('admin/transfer'));
            }

        }
    }
    else{
        $data['title'] = 'Add Transfer';
        $data['view'] = 'admin/transfer/transfer_add';
        $this->load->view('layout', $data);
    }
}

@Samira, There is no such a way to set_value in the controller. However, you can check the posted value and mark it as selected and pass in the $data but you have to check again that value to show an option as selection in the view that will make no sense.

And you should use set_select instead of set_value.

For example

<select class="form-control show-tick" id="type" name="type">
  <option value="1" <?php echo  set_select('type', '1'); ?>>Exit</option>
  <option value="2" <?php echo  set_select('type', '2'); ?>>COME</option>                         
</select>

You can see full documentation here. Set select codeigniter

One more thing, you don't need to load view twice. You can load it only once.

$this->form_validation->run() will execute only when your form is submitted.
