            return json([1, '上传成功！', 'data' => $fileName]);

            // 返回上传失败的错误信息
            return $file->getError();
        }

执行添加操作

	public function doAdd(){
		 $data = Request::param();
        $data['time'] = time();
        $data['username'] = Session::get('username');
        $newPic = new NewsPicModel();
        if ($newPic->save($data)) {
            return ['res' => 1, 'msg' => '发布成功！'];
        } else {
            return ['res' => 0, 'msg' => '发布失败！'];
        }
	}

 form.on('submit(add)', function(data){
            console.log(data);
            //发异步，把数据提交给php
            $.post('{:url(\'doAdd\')}',{
                'news_id':$('#news_id').val(),
                'pic':$('#pic').val()
            },function (data) {
                if (data.res == 1){
                    layer.alert(data.msg, {icon: 6},function () {
                        // 获得frame索引
                        var index = parent.layer.getFrameIndex(window.name);
                        //关闭当前frame
                        parent.layer.close(index);
                    });
                }else{
                    layer.alert(data.msg, {icon: 6},function () {
                        // 获得frame索引
                        var index = parent.layer.getFrameIndex(window.name);
                        //关闭当前frame
                        parent.layer.close(index);
                    });
                }
            })

            return false;
        });

NewsPic主页面显示代码如下：

	public function index(){
		$newPic=new NewsPicModel();
		$pics=$newPic->order('id','desc')->paginate(6);
		$this->assign('pics',$pics);
		
		return $this->fetch();
	}

	{volist name="pics" id="pic"}
          <tr>
     
            <td>{$pic.id}</td>
            <td>{:getTitle($pic.news_id)}</td>
            <td><img src="{$pic.pic}"></td>
      
            <td>{$pic.username}</td>
            <td>{$pic.time|date="Y-m-d H:i:s"}</td>
           
        <td class="td-manage">
                <a title="删除" onclick="member_del(this,'{$pic.id}')" href="javascript:;">
                    <i class="layui-icon">&#xe640;</i>
                </a>
            </td>
          </tr>
          {/volist}
