Answer 1

Try this

  if ($_FILES['vimage']['size'] > 0) {
    $this->load->library('upload');
     $this->upload->initialize($this->set_upload_options());
                    $this->upload->do_upload();
                    $fileName = $_FILES['vimage']['name'];

    private function set_upload_options()
      { 
      // upload an image options
             $config = array();
             $config['upload_path'] = './upload/'; //give the path to upload the image in folder
             $config['allowed_types'] = 'gif|jpg|png';
              $config['max_size'] = '0';
             $config['overwrite'] = FALSE;
      return $config;
      }

Try this

if (!empty($_FILES['vimage']))
{
    $config['upload_path'] = './uploads/';
    //$config['max_size'] = '102400';
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['overwrite'] = FALSE;
    $config['remove_spaces'] = TRUE;
    $config['encrypt_name'] = TRUE;

    $this->load->library('upload', $config);
    $this->upload->initialize($config);

    if (!$this->upload->do_upload('vimage'))
    {
        $this->session->set_flashdata('error', $this->upload->display_errors());
        //redirect('controller/method');
    }
    else
    {
        $this->session->set_flashdata('success', 'Image Has been Uploaded');
        //redirect('controller/method');
        $img = $data['file_name'];
    }

}

Please check first,

print_r(_FILES);

If you get files array then you can use below code for uploading image.

function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size']    = '100';
$config['max_width']  = '1024';
$config['max_height']  = '768';

// You can give Image formats if you want to upload any video file.

$this->load->library('upload', $config);

if ( ! $this->upload->do_upload())
{
$error = array('error' = $this->upload->display_errors());

// uploading failed. $error will holds the errors.
}
else
{
$data = array('upload_data' => $this->upload->data());

// uploading successfull, now do your further actions
}
}

I have added your code in my system it's working for fine for me.

public function add(){
        $this->load->library('upload');
        $this->load->helper('form');
        $this->load->helper('url');
         print_r($_FILES);die; 

            $this->form_validation->set_rules('title','Title','required');
            $this->form_validation->set_rules('description','Description','required');


            if ($_FILES['pro_image']['size'] > 0) {
                    $this->upload->initialize(array( 
                    "upload_path" => './uploads/',
                    "overwrite" => FALSE,
                    "encrypt_name" => TRUE,
                    "remove_spaces" => TRUE,
                    "allowed_types" => "gif|jpg|png|jpeg",
                ));


                 if (!$this->upload->do_upload('vimage')) {
                     $this->upload->display_errors();
                 }

                 $data = $this->upload->data();
                 echo 'img : '.$img = $data['file_name'];
            } 
            exit;

            if($this->form_validation->run()==FALSE){
                echo '<div class="alert alert-dismissable alert-danger"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button><small>'.  validation_errors().'</small></div>';
            }
            else {
                $title = $this->input->post('title');
                $description = $this->input->post('description');
                $artist_dir = $this->input->post('artist_dir');
                $highlight = $this->input->post('highlight');
                $this->promotions_model->add_item($title, $description,$artist_dir,$highlight);
            }


    }
