Slide.php

这里面有个DoAdd添加操作，这操作之前要先upload 做这个操作，即上传播图upload()方法，代码如下：

<?php
namespace app\admin\controller;
use app\admin\model\SlideModel;
use app\admin\controller\Common;
use think\facade\Request;
use think\facade\Session;
class Slide extends Common{
	public function index(){
		$slides=SlideModel::all();
		$this->assign('slides',$slides);
		return $this->fetch();
	}
	
	public function add(){
		return $this->fetch();
	}
	
	public function upload(){
		$file=Request::file('file');
		if($info=$file->validate(['ext'=>'jpg,jpeg,gif,png'])->move('upload')){
			$fileName='/upload/'.$info->getSaveName();
			return json([1,'上传成功','data'=>$fileName]);
		}else{
			return $file->getError();
		}
	}
	
	public function DoAdd(){
		$data=Request::param();
		$data['time']=time();
		$data['username']=Session::get('username');
		$slide=new SlideModel();
		$info=$slide->save($data);
		if($info){
			return ['res'=>1,'msg'=>'添加成功'];
		}else{
			return ['res'=>0,'msg'=>'添加失败'];
		}
	}
	
	
	 public function del()
    {
        // 获取需要删除的id
        $slideId = Request::param('id');
        // 实例化模型
        $slide = new SlideModel();
        // 删除并验证
        if ($slide->destroy($slideId)) {
            return ['res' => 1];
        }

    }	  
}

add.html

url: "{:url('upload')}",

$.post("{:url()}",{data},function(data){})

<script>
    layui.use(['form', 'layer', 'upload'], function () {
        $ = layui.jquery;
        var form = layui.form
            , layer = layui.layer,
            upload = layui.upload;

        upload.render({
            elem: '#upload',
            url: "{:url('upload')}",
            multiple: true,
            before: function (obj) {
                //预读本地文件示例，不支持ie8
                obj.preview(function (index, file, result) {
                    $('#thumbnail').append('<img src="' + result + '" alt="' + file.name + '" class="layui-upload-img">')
                });
            },
            done: function (res) {
                //上传完毕
                $('#thumbnail').append('<input type="hidden"  name="slide_pic" id="slide_pic" value="' + res.data + '" />')
            }
        });

        //监听提交
        form.on('submit(add)', function (data) {
            console.log(data);
            //发异步，把数据提交给php
            $.post('{:url(\'DoAdd\')}', {
                'pic': $('#slide_pic').val(),
                'desc': $('#desc').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;
        });
    });
</script>

index()方法的index.html展示如下：

	{volist name="slides" id="slide"}
        <tr>
            <td>{$slide.id}</td>
            <td>
                <img src="{$slide.pic}">
            </td>
            <td>{$slide.desc}</td>
            <td>{$slide.username}</td>
            <td>{$slide.time|date="Y-m-d"}</td>
            <td class="td-manage">
                <button class="layui-btn-danger layui-btn layui-btn-xs" onclick="member_del(this,'{$slide.id}')"
                        href="javascript:;"><i class="layui-icon">&#xe640;</i>删除
                </button>
            </td>
        </tr>
        {/volist}
