php - Codeigniter Upload Files/image only works when offline -


i made code upload files on web, when still using xampp, going well, after upload hosting, file uploading not working..

here's code :

model (for updating database record)

function edit_logo_web()     {     $timestamp = date('ymdhi');     $img = $_files['userfile']['name'];     $logo = $timestamp."_".$img;     $data = array (     'logo'  => $logo     );     $id = 1;     $this->db->where('site.id', $id);        if($this->upload->do_upload()){     $this->db->update('site', $data);}     else{     }     }

controller (for uploading img/file web directory)

    function logo_web()         {         $timestamp = date('ymdhi');         $img = $_files['userfile']['name'];         $config['file_name'] = $timestamp."_".$img;         $config['upload_path'] ='asset/img/';         $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg|png';         $config['max_size']    = '1024';         $config['max_width']  = '1600';         $config['max_height']  = '1200';         $config['remove_spaces'] = false;         $this->load->library('upload', $config);         $data = array('upload_data' => $this->upload->data());         $this->m_cmm_bimbel->edit_logo_web();         echo "<script>         alert('success !!');         window.location.href='logo_web';         </script>";     }
