foreach和volist标签实现数据库中的记录在网页中分页显示。
实现效果:
foreach分页
volist分页
<?php namespace app\index\controller; use think\Controller; use app\index\model\Car as CarModel; class Car extends Controller { // 分页 public function pages() { // 分页配置 $config = [ 'type' => 'bootstrap', 'var_page' => 'page' ]; // 每个分页显示数量 $num = 5; // 是否简单分页 $simple = false; // 用模型获取所有分页数量:think\paginate $paginate = CarModel::paginate($num, $simple, $config); // 渲染分页html,返回分页变量(生成html代码) $page = $paginate->render(); // 将分页数据赋值给模板 $this->view->assign('cars', $paginate); // 将分页变量赋值给模板 $this->view->assign('page', $page); // 渲染模板(将生成的html代码编译到网页中显示) return $this->view->fetch(); } }

知识点:
分页类是抽象类,无法直接实例化,需要继承在子类中实例化;
thinkphp5.1.14中使用bootstrap为分页默认前端框架,如果要自定义,自己写分页类放到thinkphp/library/paginator/driver下,并继承paginator
模板标签{in}:枚举,离散值
模板标签{between}:连续数据
