<section>
    <h2>Add Gallery</h2>

控制器(画廊)

public function gallery()
{

    $this->load->library('upload');

    $files = $_FILES;
    $cpt = count($_FILES['files']['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES['files']['name']= $files['files']['name'][$i];
        $_FILES['files']['type']= $files['files']['type'][$i];
        $_FILES['files']['tmp_name']= $files['files']['tmp_name'][$i];
        $_FILES['files']['error']= $files['files']['error'][$i];
        $_FILES['files']['size']= $files['files']['size'][$i];    

        $this->upload->initialize($this->set_upload_options());
        // $this->upload->do_upload('files[]');
        if (!$this->upload->do_upload('files[]'))
        {  
            $error =['error' => $this->upload->display_errors()];
            $this->load->view('admin/addGallery', $error);
        }
    }
}
public function set_upload_options()
{
    $config['upload_path'] = getcwd().'/upload/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['remove_spaces'] = true;
    return $config;
}

默认情况下，codeIgniter 不支持多文件上传。所以你可以使用这个库CodeIgniter Multiple Upload Library
