1.创建控制器 app\Http\Controllers\NewsController.php
<?php
namespace App\Http\Controllers;
use App\News;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class NewsController extends Controller {
public function index() {
$news = News::all();
//return $news;//直接返回json
return view('news.index', compact('news')); //返回视图
}
public function detail($id) {
//$row = News::findOrFail($id);
$row = News::getOne($id);
return view('news.detail', compact('row'));
}
}
2、创建模型 app\News.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use DB;
class News extends Model {
//use SoftDeletes;
static function getOne($id) {
$row = DB::table('news')->where('id', $id)->first();
//$row = DB::select("SELECT * FROM news WHERE id='$id'");
return $row;
}
}<strong>
</strong>
3、创建视图，laravel使用的是Blade模板引擎，同时也支持php原生写法
resources\views\news\index.blade.php
<html>
<head>
<title>新闻列表</title>
</head>
<body>
<h2>新闻列表</h2>
<div class="container">
@foreach($news as $row)
<article>
<a href="{{url('news/detail/'.$row->id)}}">{{$row->title}}</a>
</article>
@endforeach
</div>
</body>
</html>
resources\views\news\detail.blade.php
<html>
<head>
<title>新闻详情</title>
</head>
<body>
<h2>新闻详情</h2>
<div class="container">
<p>标题：{{$row->title}}</p>
<p>内容：{{$row->content}}</p>
<p>投稿人：{{$row->username}}</p>
</div>
</body>
</html>
创建model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Member extends Model
{
public static function getMember()
{
return 'member name is sean';
}
}
3、在控制器当中使用
<?php
namespace App\Http\Controllers;
use App\Member;
class MemberController extends Controller
{
public function info($id)
{
//调用模型
return Member::getMember();
}
}
