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{
  2. /**
  3. * 附件上传
  4. * @param string $type 文件类型:jpg,png
  5. * @param int $maxsize 最大上传容量:默认100Kb
  6. * @param string $model 上传所在模块
  7. * @param bool $insert 是否写入数据库
  8. * @param bool $thumb 是否生成缩略图
  9. * @param string $wh 缩略图的宽高
  10. * Example: $upload->upload(null,102400,APP_NAME,true,true,array('300','225'));
