//设值name为username的验证规则
$this->form_validation->set_rules('username','用户姓名','required|min_length[6]');

//设置myfile的验证   
$this->form_validation->set_rules('myfile','上传文件','required');

//执行以上验证
$res = $this->form_validation->run();
//返回结果验证通过为true,验证失败为false
var_dump($res);
//echo form_error('username');

/*  $config = array(
