Cara upload,menampilkan,update foto user dengan php codeigniter

kalo untuk upload satu file mungkin bisa pake ini :

Controllers :

$this->load->helper(array('form', 'url'));
$photo = $photo;
$this->load->library('upload');
$config['upload_path'] = './uploads/userphoto/'; // Sesuaikan sama folder dimana foto akan d simpan
$config['allowed_types'] = 'gif|jpg|png|jpeg|bmp';
$config['max_size'] = '2048';
$config['max_width']  = '1288';
$config['max_height']  = '768';

$this->upload->initialize($config);
  if(!$this->upload->do_upload('photo')){
      $photo="";
  }else{
      $photo=$this->upload->file_name;
}
$data = array(
     'photo' => $photo,
);

$this->model_kamu->function_di_model($data); // kalo saya pake function add_account di model

Models :

function add_account($data)
{
  $this->load->database();
  $this->db->insert('tbl_user',$data);
}

Views :

<form class="form-horizontal" action="<?php echo base_url();?>controller_kamu/function_kamu"  method="post" enctype="multipart/form-data">
<div class="form-group">
    <div class="col-xs-12">
      <label for="photo">Photo Profile</label>
      <input type="file" name="photo" class="form-control" required />
    </div>
</div>

kalo untuk nampilin & update sesuaikan juga sama folder penyimpanan fotonya. saya kasih contoh gini :

<img src="<?php echo base_url('uploads/userphoto/'.$row->photo.'');?>" height="50px" width="50px">

yang di upload itu hanya nama file nya aja di database bukan foto nya, fotonya hanya di simpan di folder yang kamu udah tentuin tadi pas di simpan gambar.

CMIIW !
