Multiupload not cycle

I want to create a multi-upload function, but I can only upload one file.
The upload function does not cycle

View

PHP Code:

.....
.....
echo form_open_multipart('Upload');
echo '<br/>Upload file(s):<br />';
echo '<br />'.form_upload('files[]','','multiple');
echo '<br />'.form_upload('files[]','','multiple'); 
echo '<br />'.form_upload('files[]','','multiple');
echo '<br /><br />'.form_submit('submit','Upload');
echo form_close();
.....
..... 


Controller

PHP Code:

......
......
public function upload_do()
{
  $this->load->helper('form'); $data = array(); $messaggi='';
  $data['title'] = 'Multiple file upload';
  $number_of_files = count($_FILES['files']['name']);
  $files = $_FILES['files']; $errors = array();
  $this->load->library('upload');
  $config['upload_path'] = $this->session->userdata('upload');

  for ($i=0; $i<$number_of_files; $i++)
  {
   if($_FILES['files']['size'][$i]>0){
   $_FILES['files']['name'] = $files['name'][$i];
   $_FILES['files']['type'] = $files['type'][$i];
   $_FILES['files']['tmp_name'] = $files['tmp_name'][$i];
   $_FILES['files']['error'] = $files['error'][$i];
   $_FILES['files']['size'] = $files['size'][$i];
   $this->upload->initialize($this->set_upload_options());
   if ($this->upload->do_upload('files'))
   {
    data['uploads'][$i] = $this->upload->data();
    $nome_encrypt = $data['uploads'][$i]['file_name'];
    foreach($this->upload->data() as $dati){echo 'filedata: '.$dati'<br/>'; }
   }
    else
    {
     echo 'error: '.$this->upload->display_errors();
     $data['upload_errors'][$i] = $this->upload->display_errors();
    }
  }
}
 .......
 .......
} 


Help me

If I remove $ _FILES ['files'][ 'size'] the cycle works, but does not upload any file.

Check your php.ini file, there are settings in there for uploading

Also you need to set these two in php.ini file for file sizes.

upload_max_filesize = 10M
post_max_size = 10M

These two should contain the same value.

What did you Try? What did you Get? What did you Expect?

} 


If a line is empty, the upload operation stops
Why?
