完成模型中的CURD操作,全部采用静态方法;


实例

<?php
namespace app\index\controller;
use app\model\User;
use traits\controller\Jump;
class Demo2
{
    use Jump;
    public function getOne(){
//        $res = User::get(1);
//        dump($res);

        $salary = 5000;
        $res = User::all(function ($query)use ($salary){
            $query->where('age','>',25)
                ->where('salary','>',$salary);
        });
        foreach ($res as $user){
            echo $user->name,'->',$user->salary,'<br>';
        }
    }

    public function getAll(){
        $salary = 5000;
        $res = User::all(function ($query)use ($salary){
            $query->where('age','>',25)
                ->where('salary','>',$salary);
        });
        dump($res);
    }

    public function update(){
        User::update(['age'=>33],['id'=>4]);
        $this->success('更新成功','show');
    }

    public function show(){
        dump(User::where('id',4)->field('id,age,name')->select());
    }

练习视图中的assign()和fetch()方法


实例

<?php
namespace app\index\controller;
use think\facade\View;
use app\model\User;
class Demo3
{
    public function index(){
        $site = '小渣渣';
        $user = User::get(4);
        $list = User::all();


        View::assign('lee',$site);
        View::assign('user',$user);
        View::assign('list',$list);


        return View::fetch('index');

试着找一个后台模块,并将首页导入到框架项目中。


实例

<?php
namespace app\index\controller;
use think\facade\View;
class Index
{
    public function index()
    {
        return View::fetch('index');
    }

    public function welcome(){
        return View::fetch('welcome');
    }

    public function hello($name = 'ThinkPHP5')
    {
        return 'hello,' . $name;
    }
}
