laravel的MVC

一、laravel路由（应用中的大多数路由都会定义在 app/routes.php 文件中）

routes.php

1 Route::get('/test','TestController@index');

一个路由就定义好了，当访问 http://xxx.com/public/index.php/test 时就会去找 app/controllers/TestController.php的index方法 
TestController.php 

1 class TestController extends Controller{
2     public function index(){
3         echo "hello world";
4     }
5 }

一个控制器就建立好了，控制器也可以设置闭包，也可以设置别名 

1 Route::get('user/profile', array('as' => 'profile', function()
2 {
3     echo "hello world";
4 }));

更多路由请看手册：  http://www.golaravel.com/docs/4.1/routing/

二、模型 
普通数据库操作

1 $results = DB::select('select * from users where id = ?', array(1));//查
2 $results = DB::insert('insert into users (id, name) values (?, ?)', array(1, 'Dayle'));//增
3 $results = DB::update('update users set votes = 100 where name = ?', array('John'));//更新
4 $results = DB::delete('delete from users where id = ?',array(1));//删

查询生成器

01 //查
02 $obj = DB::table('archives')->select('archives.*','arctype.typename')->where('archives.id','>',2)->join('arctype','arctype.id','=','archives.typeid','left')->orderBy('archives.id','desc')->skip(10)->take(5)->get();//查多条数据
03 $obj = DB::table('archives')->where('typeid','=','1')->orderBy('id','desc')->first();//查询一条数据
04 //where条件分组
05 $sql = DB::table('archives')
06     ->where('typeid', '=', 1)
07     ->orWhere(function($query)
08     {
09         $query->where('id', '>', 2)
10                 ->where('title', '<>', 'Admin');
11     })
12     ->get();//sql语句: select * from `la_archives` where `typeid` = 1 or (`id` > 2 and `title` <> 'Admin')
13 //聚合查询
14 $users = DB::table('archives')->count();//查总数
15 $price = DB::table('archives')->max('id');//查最大值
16 $price = DB::table('archives')->min('id');//查最小值
17 $price = DB::table('archives')->avg('id');//查平均值
18 $total = DB::table('archives')->sum('id');//查和
19 //增
20 $data = array('title'=>'标题八','body'=>'内容八','typeid'=>2);
21 $obj = DB::table('archives')->insert($data);
22 //改
23 $data2 = array('title'=>'标题九','body'=>'内容九','typeid'=>2);
24 $obj = DB::table('archives')->where('id',2)->update($data2);
25 //删
26 $obj = DB::table('archives')->where('id','>','100')->delete();

//模型（app/models/Archives.php）

1 class Archives extends Eloquent{
2     protected $table = 'archives';//表名
3     public $timestamps  = false;//不自动维护更新时间
4 }

//模型操作和普通SQL查询一样 

1 $arr = Archives::select('archives.*','arctype.typename')->where('archives.id','>',2)->join('arctype','arctype.id','=','archives.typeid','left')->orderBy('archives.id','desc')->skip(0)->take(10)->get();
2 $data = array('title'=>'新标题','body'=>'新内容');
3 $arr = Archives::where('id','=',2)->update($data);

三、视图（app/views/home/test.blade.php）

1 <?php
2     foreach($items as $k=>$v){
3         echo $v->title.'<br>';
4     }
5 ?>

 

 

控制器中

 

 

1 public function test(){
2    $data = Archives::select('*')->get();
3    return View::make('home.test')->with('items',$data);
4 }
