摘要：新闻缩略图控制器代码：<?php namespace app\admin\controller; use app\admin\controller\Common; use app\admin\model\NewsModel; use app\admin\model\NewsPicModel; use think\facade\Request;
新闻缩略图控制器代码：
<?php namespace app\admin\controller; use app\admin\controller\Common; use app\admin\model\NewsModel; use app\admin\model\NewsPicModel; use think\facade\Request; use think\facade\Session; /** * */ class NewsPic extends Common { public function index(NewsPicModel $newPic){ $pics=$newPic->order('id','desc')->paginate(6); //新闻缩略图列表 $count = $newPic->count(1); $this->view->pics=$pics; $this->view->count=$count; return $this->view->fetch(); } public function add(NewsModel $news){ $news=NewsModel::all(); $this->view->news=$news; //添加缩略图 return $this->view->fetch(); } public function upload(){ $file=Request::file('file'); if ($info=$file->validate(['ext'=>'jpg,jpeg,png,gif'])->move('upload')) { $fileName='/upload/'.$info->getSaveName(); return json([1,'上传成功','data'=>$fileName]); }else{ return $file->getError(); } } public function DoAdd(NewsPicModel $newPic){ //获取提交的信息 $data=Request::param(); $data['time']=time(); $data['username']=Session::get('username'); if ($newPic->save($data)) { return ['res'=>1,'msg'=>'发布成功！']; }else{ return ['res'=>0,'msg'=>'发布失败！']; } } public function del(NewsPicModel $newPic){ $picId=Request::param('id'); if($newPic->destroy($picId)){ return ['res'=>1,'msg'=>'删除成功']; }else{ return ['res'=>0,'msg'=>'删除失败']; } } } ?>3.模型代码：
<?php namespace app\admin\model; use think\Model; class NewsPicModel extends Model { protected $table="news_pic"; //设置主键 protected $key="id"; } ?>4.视图中index.html代码
{include file="/public/header"} <body> <div class="x-nav"> <span class="layui-breadcrumb"> <a href="">首页</a> <a href="">演示</a> <a> <cite>导航元素</cite></a> </span> <a class="layui-btn layui-btn-small" style="line-height:1.6em;margin-top:3px;float:right" href="javascript:location.replace(location.href);" title="刷新"> <i class="layui-icon" style="line-height:30px">ဂ</i></a> </div> <div class="x-body"> <xblock> <button class="layui-btn" onclick="x_admin_show('添加用户','{:url(\'NewsPic/add\')}')"><i class="layui-icon"></i>添加</button> <span class="x-right" style="line-height:40px">共有数据：{$count} 条</span> </xblock> <table class="layui-table"> <thead> <tr> <th>图片ID</th> <th>所属新闻</th> <th>新闻图片</th> <th>发布管理员</th> <th>发布日期</th> <th >操作</th> </tr> </thead> <tbody> {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>{$pic.time|date='Y-m-d H:s:i'}</td> <td class="td-manage"> <a title="删除" onclick="member_del(this,'{$pic.id}')" href="javascript:;"> <i class="layui-icon"></i> </a> </td> </tr> {/volist} </tbody> </table> <div class="page"> </div> </div> <script> layui.use('laydate', function(){ var laydate = layui.laydate; //执行一个laydate实例 laydate.render({ elem: '#start' //指定元素 }); //执行一个laydate实例 laydate.render({ elem: '#end' //指定元素 }); }); /*用户-删除*/ function member_del(obj,id){ layer.confirm('确认要删除吗？',function(index){ //发异步删除数据 $.get('{:url("del")}','id='+id,function(data){ if (data.res==1) { $(obj).parents("tr").remove(); layer.msg(data.msg,{icon:1,time:1000});} }) $(obj).parents("tr").remove(); layer.msg(data.msg,{icon:1,time:1000}); }); } </script> </body> </html>5.视图中add.html代码：
{include file="/public/header"} <body> <div class="x-nav"> <span class="layui-breadcrumb"> <a href="">首页</a> <a href="">演示</a> <a> <cite>导航元素</cite></a> </span> <a class="layui-btn layui-btn-small" style="line-height:1.6em;margin-top:3px;float:right" href="javascript:location.replace(location.href);" title="刷新"> <i class="layui-icon" style="line-height:30px">ဂ</i></a> </div> <div class="x-body"> <xblock> <button class="layui-btn" onclick="x_admin_show('添加用户','{:url(\'NewsPic/add\')}')"><i class="layui-icon"></i>添加</button> <span class="x-right" style="line-height:40px">共有数据：{$count} 条</span> </xblock> <table class="layui-table"> <thead> <tr> <th>图片ID</th> <th>所属新闻</th> <th>新闻图片</th> <th>发布管理员</th> <th>发布日期</th> <th >操作</th> </tr> </thead> <tbody> {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>{$pic.time|date='Y-m-d H:s:i'}</td> <td class="td-manage"> <a title="删除" onclick="member_del(this,'{$pic.id}')" href="javascript:;"> <i class="layui-icon"></i> </a> </td> </tr> {/volist} </tbody> </table> <div class="page"> </div> </div> <script> layui.use('laydate', function(){ var laydate = layui.laydate; //执行一个laydate实例 laydate.render({ elem: '#start' //指定元素 }); //执行一个laydate实例 laydate.render({ elem: '#end' //指定元素 }); }); /*用户-删除*/ function member_del(obj,id){ layer.confirm('确认要删除吗？',function(index){ //发异步删除数据 $.get('{:url("del")}','id='+id,function(data){ if (data.res==1) { $(obj).parents("tr").remove(); layer.msg(data.msg,{icon:1,time:1000});} }) $(obj).parents("tr").remove(); layer.msg(data.msg,{icon:1,time:1000}); }); } </script> </body> </html>6.为返回数据更加直接易懂，利用common文件将缩略图列表中的新闻id转为新闻标题。
function GetTitle($news_id){
return Db::connect('qiye')->table('news')->where('id',$news_id)->value('title');
