thinkphp图片上传缩略图代码解释

PHP代码如下(附说明):

 1     public function add(){
 2         if(IS_POST){
 3             $goods = M("goods");
 4             $data = $_POST;
 5             $data["on_time"] = date('Y-m-d H:s');
 7             $conf = array(
 8                 "rootPath" => "./app/upload/"
 9             );
10             $uploads = new upload($conf);
11             $info = $uploads -> uploadOne($_FILES["original_img"]);
14             $data["original_img"] = $info["savepath"].$info["savename"];
16             $image = new Image();
17             $big_img = $uploads ->rootPath.$info["savepath"].$info["savename"];
19             $image ->open($big_img);
21             $image ->thumb(150,150,6);
23             $small_img = $uploads ->rootPath.$info["savepath"].'small_'.$info["savename"];
24             $image ->save($small_img);
25             $data['keywords'] = $info["savepath"].'small_'.$info["savename"];
26             $goods -> add($data);
27             $this -> redirect("zhanshi",array(),1,"添加成功");
28             
29         }

html视图代码(附说明):

2 <td><img src="{$Think.const.UPLOAD_PATH}{$vo.keywords}" height="40" width="40"></td>

　　路径常量代码(附说明):
