html代码，主要处理都是在jq中，完成方法全部原创，也许不是最简单的，但也能实现效果

                'size'=>320000000,//最大3M
            ];
            //6、对上传的文件进行较验，如果合格就进行转移到预定设定好的public/uploads目录下
            //返回保存的文件信息info，包括文件名和大小等数据
            $info = $file->validate($map)->move(ROOT_PATH . 'public/uploads/img');
            //获取图片宽高
            list( $width , $height , $type , $attr ) = getimagesize ($info->getPathName());
 
            if(is_null($info)){

 //多选图片添加页面
    public function addImages(){

            if(is_null($res)){
                $this->error('文件添加失败');
            }else{
                $this->success('文件添加成功...',url('imagesList'));
            }
            return;
        }
        return $this->fetch('images_add');
