分页
controller
public function demo2() { //分页配置 $config = [ 'type' => 'bootstrap', 'var_page' => 'page', ]; //每页数量 $num = 5; //是否是简单分页 $simple = false; //获取所有分页数据:返回值是分页对象: think\Paginate $paginate = StaffModel::paginate($num, $simple, $config); //渲染分页的HTML,返回分页变量 $page = $paginate->render(); //将分页对象赋值给模板 $this->view->assign('staffs', $paginate); //将分页变量赋值给模板 $this->view->assign('page', $page); //渲染模板 return $this->view->fetch(); //备注: tp51自带的分页功能很不灵活,更多时候,推荐使用自己写的分页类 }
<div class="text-center">{$page|raw}</div>
文件上传

<h3>文件上传</h3> <form action="demo4" method="post" enctype="multipart/form-data"> <input type="file" name="file"> <button>提交</button> </form>

Teacher's summary:上传、分页在实际的项目中基本上哪里有会用到!课后一定要多多练习!
