thinkphp图片上传缩略图代码解释

PHP代码如下(附说明):

 

    public function add(){
        if(IS_POST){
            $goods = M("goods");
            $data = $_POST;
            $data["on_time"] = date('Y-m-d H:s');
            $conf = array(
                "rootPath" => "./app/upload/"
            );
            $uploads = new upload($conf);
            $info = $uploads -> uploadOne($_FILES["original_img"]);
            $data["original_img"] = $info["savepath"].$info["savename"];
            $image = new Image();
            $big_img = $uploads ->rootPath.$info["savepath"].$info["savename"];
            $image ->open($big_img);
            $image ->thumb(150,150,6);
            $small_img = $uploads ->rootPath.$info["savepath"].'small_'.$info["savename"];
            $image ->save($small_img);
            $data['keywords'] = $info["savepath"].'small_'.$info["savename"];
            $goods -> add($data);
            $this -> redirect("zhanshi",array(),1,"添加成功");
            
        }
