记录一次php图片上传浏览删除操作

总会遇到一些问题,比如上传图片,我采用thinkphp来作为服务端操作,上代码:

Public function upload($folderName) {
        import('ORG.Net.UploadFile');
        $upload = new \Think\Upload(); // 实例化上传类
        $upload->replace = true;
        $upload->maxSize = 5242880; // 设置附件上传大小
        $upload->exts = array('jpg', 'gif', 'png', 'jpeg','bmp'); // 设置附件上传类型
        $upload->rootPath = './Public/Uploads/'; // 设置附件上传根目录
        $upload->savePath = ''; // 设置附件上传(子)目录
        $upload->autoSub = true;//设置是否自动创建文件夹
        $upload->subName = $folderName?$folderName:array('date','Y-m-d');
        // 上传文件 
        $info = $upload->upload();
        $path = $upload->rootPath;
        $data['msg']='';
        if (!$info) {// 上传错误提示错误信息
            $data['ok'] = false;
            $data['msg']=$upload->getError();
        } else {// 上传成功
            $savefile = $info['file'];
            $path.=$savefile['savepath'] . $savefile['savename'];
            $data['msg'] = '上传成功';
            $data['ok'] = true;
            $data['path'] = $path;
            //$this->success('上传成功!');
        }
        return $data;
//        $this->ajaxReturn($data);
    }
  /**
     * 删除上传文件
     * @param type $filename
     * @return type
     */
    public function delFile($filename){
        return unlink($filename);
    }
 /**
     * 根据文件目录循环文件名
     */
    public function openCktp() {
        $dir = opendir('./Public/Uploads/cktp');
        $list = array();
        while ($file = readdir($dir)) {
            if (($file == '.' || $file == '..')) {
                continue;
            }
            array_push($list, $file);
        }
        closedir($dir);
        $this->ajaxReturn($list);
    }
