<?php 
namespace app\index\controller;
use think\Controller;
use app\index\model\User as UserModel;	//引入model中命名空间里面的类->的别名;

class User extends Controller
{
	//模板赋值;
	public function demo1(){
		//通过助手函数调用all(获取所有信息)方法,$query为条件
		$users = UserModel::all(function($query){
			$query->field('*');
		});

		//模板赋值;	在视图中也可以模板赋值;
		// $this->view->assign('users',$users);
		//模板渲染;
		return $this->view->fetch();	//默认视图为user.html;
	}


	// 分页主要用到的类为paginator.php的一个抽象类,bootstrap.php类继承了这个抽象类,所以实例化bootstrap类即可
	// 分页
	public function demo2(){

		//分页配置;
		$config = ['type' =>'bootstrap','var_page' =>'page'];
		//显示数量;
		$num = 5;
		//是否为简单分页;
		$simple = false;
		//用模型获取分页数据;	think\paginate;
		$pagelist = UserModel::paginate($num,$simple,$config);
		//渲染分页html代码,(进入下一页的导航);
		$page = $pagelist->render();
		$this->view->assign('users',$pagelist);
		$this->view->assign('page',$page);
		return $this->view->fetch();
