ThinkPHP上传图片是否存否数据库类

看下项目要求：可以选择是否存入数据库，指定文件类型，文件大小，缩略图及缩略图大小

1. class AttachModel extends Model{
3. /**
4. * 附件上传
5. * @param string $type 文件类型：jpg,png
6. * @param int $maxsize 最大上传容量:默认100Kb
7. * @param string $model 上传所在模块
8. * @param bool $insert 是否写入数据库
9. * @param bool $thumb 是否生成缩略图
10. * @param string $wh 缩略图的宽高
11. * Example: $upload->upload(null,102400,APP_NAME,true,true,array('300','225'));
12. */
