    $this->form_validation->set_rules('price', 'price', 'required'); 

    $this->load->helper(array('form', 'url')); 
    if ($this->form_validation->run() == TRUE) 
    { 
     $this->load->view('admin/add_view.php'); 
     $config['upload_path'] = './files/'; 
     $config['allowed_types'] = 'jpg'; 
     $this->load->library('upload', $config); 
     $this->upload->do_upload('picture'); 
     $this->upload->data(); 

     $data = array(
      'name' => $this->input->post('name'),

enctype="multipart/form-data" in Form fehlt

Read php file upload

Und Upload-Code sollte wie folgt sein. Seine leicht zu Ihre Fehler

if(!$this->upload->do_upload()) # do_upload('picture'); 
{ 
    echo $this->upload->display_errors(); 
} 
else 
{ 
    $data = $this->upload->data(); 
    print_r($data); 
}
