Mysql insertion problem with Multi upload

Question

I have a system that performs multi file upload, I am using the Codeigniter framework that extends to Class Upload CI. The files are being moved correctly to the desired folder, however when entering the database records only one.

Controller:

  if ($this->form_validation->run() == TRUE):
        $upload = $this->protocolo->do_upload('arquivo');
        if (is_array($upload) && $upload['file_name'] != ''):
        $dados['arquivo'] = $upload['file_name'];
        $this->protocolo->do_insert($dados);
    endif;

View:

echo form_label('Arquivo');
echo form_upload(array('name' => 'arquivo[]', 'class' => 'arquivo', 'multiple' => ''), set_value('arquivo'));

Upload model:

 public function do_upload($campo = 'arquivo') {
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|pdf';
    $config['encrypt_name'] = TRUE;
    $this->load->library('upload', $config);
    if ($this->upload->do_multi_upload($campo)):
        return $this->upload->data();
        else:
        return $this->upload->display_errors();
    endif;
}

Data insertion model:

public function do_insert($dados = NULL) {
    if ($dados != NULL):
        $this->db->insert('protocolo', $dados);
    endif;
}

I performed a test, I used a function that the multi upload class offers, called get_multi_upload_data() and she returned me the data correctly:

 if ($this->form_validation->run() == TRUE):
    $upload = $this->protocolo->do_upload('arquivo');
    if (is_array($upload) && $upload['file_name'] != ''):
        echo '<pre>';
            $upload = $this->upload->get_multi_upload_data();
            print_r($upload);
        echo '</pre>';

            [image_size_str] => width="1029" height="772"
        )

)

The problem is only in the insertion of the BD, it is inserting only one record, someone has idea of what can be?

See if this code can help you.

<?php

                $len2 = count($_FILES['files']['name']);

                        // Adiciona no array para inserir no banco
                        $arr[] = array(

            }
