路由
在 learnlaravel5/app/Http/routes.php 的末尾添加以下代码：
Route::group(['prefix' => 'admin', 'namespace' => 'Admin'], function()
{
Route::get('/', 'AdminHomeController@index');
});
这表示创建了一个路由组。
'prefix' => 'admin' 表示这个路由组的 url 前缀是 /admin，也就是说中间那一行代码 Route::get('/' 对应的链接不是 http://fuck.io:88/ 而是 http://fuck.io:88/admin ，如果这段代码是 Route::get('fuck' 的话，那么 URL 就应该是 http://fuck.io:88/admin/fuck 。
'namespace' => 'Admin' 表示下面的 AdminHomeController@index 不是在 \App\Http\Controllers\AdminHomeController@index 而是在 \App\Http\Controllers\Admin\AdminHomeController@index，加上了一个命名空间的前缀。
控制器
执行命令
php artisan make:controller Admin/AdminHomeController
得到 learnlaravel5/app/Http/Controllers/Admin/AdminHomeController.php 文件。
在 class AdminHomeController extends Controller { 上面增加一行：
use App\Page;
修改 index() 的代码如下：
public function index()
{
return view('AdminHome')->withPages(Page::all());
}
视图
新建 learnlaravel5/resources/views/AdminHome.blade.php：
@extends('app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-10 col-md-offset-1">
<div class="panel panel-default">
<div class="panel-heading">后台首页</div>
<div class="panel-body">
<a href="{{ URL('admin/pages/create') }}" class="btn btn-lg btn-primary">新增</a>
@foreach ($pages as $page)
<hr>
<div class="page">
<h4>{{ $page->title }}</h4>
<div class="content">
<p>
{{ $page->body }}
</p>
</div>
</div>
<a href="{{ URL('admin/pages/'.$page->id.'/edit') }}" class="btn btn-success">编辑</a>
<form action="{{ URL('admin/pages/'.$page->id) }}" method="POST" style="display: inline;">
<input name="_method" type="hidden" value="DELETE">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<button type="submit" class="btn btn-danger">删除</button>
</form>
@endforeach
</div>
</div>
</div>
</div>
</div>

完成 Pages 管理功能
4.1 修改路由 learnlaravel5/app/Http/routes.php
Route::group(['prefix' => 'admin', 'namespace' => 'Admin'], function()
{
Route::get('/', 'AdminHomeController@index');
Route::resource('pages', 'PagesController');
});
4.2 创建 learnlaravel5/app/Http/Controllers/Admin/PagesController.php
运行：
php artisan make:controller Admin/PagesController
4.3 修改 learnlaravel5/app/Http/Controllers/Admin/PagesController.php 为：
<?php namespace App\Http\Controllers\Admin;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Page;
use Redirect, Input, Auth;
class PagesController extends Controller {
/**
*Show the form for creating a new resource.
*@return Response
*/
public function create()
{
return view('admin.pages.create');
}
/**
*Store a newly created resource in storage.
*@return Response
*/
public function store(Request $request)
{
$this->validate($request, [
'title' => 'required|unique:pages|max:255',
'body' => 'required',
]);
$page = new Page;
$page->title = Input::get('title');
$page->body = Input::get('body');
$page->user_id = 1;//Auth::user()->id;
if ($page->save()) {
return Redirect::to('admin');
} else {
return Redirect::back()->withInput()->withErrors('保存失败！');
}
}
/**
* Show the form for editing the specified resource.
* @param int $id
* @return Response
*/
public function edit($id)
{
return view('admin.pages.edit')->withPage(Page::find($id));
}
/**
* Update the specified resource in storage.
* @param int $id
* @return Response
*/
public function update(Request $request,$id)
{
$this->validate($request, [
'title' => 'required|unique:pages,title,'.$id.'|max:255',
'body' => 'required',
]);
$page = Page::find($id);
$page->title = Input::get('title');
$page->body = Input::get('body');
$page->user_id = 1;//Auth::user()->id;
if ($page->save()) {
return Redirect::to('admin');
} else {
return Redirect::back()->withInput()->withErrors('保存失败！');
}
}
/**
* Remove the specified resource from storage.
* @param int $id
* @return Response
*/
public function destroy($id)
{
$page = Page::find($id);
$page->delete();
return Redirect::to('admin');
}
}4.4 创建视图文件
首先在 learnlaravel5/resources/views 下创建 admin/pages 两级文件夹。
然后创建 learnlaravel5/resources/views/admin/pages/create.blade.php：
@extends('app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-10 col-md-offset-1">
<div class="panel panel-default">
<div class="panel-heading">新增 Page</div>
<div class="panel-body">
@if (count($errors) > 0)
<div class="alert alert-danger">
<strong>Whoops!</strong> There were some problems with your input.<br><br>
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form action="{{ URL('admin/pages') }}" method="POST">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="text" name="title" class="form-control" required="required">
<br>
<textarea name="body" rows="10" class="form-control" required="required"></textarea>
<br>
<button class="btn btn-lg btn-info">新增 Page</button>
</form>
</div>
</div>
</div>
</div>
</div>
@endsection
之后创建 learnlaravel5/resources/views/admin/pages/edit.blade.php：
@extends('app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-10 col-md-offset-1">
<div class="panel panel-default">
<div class="panel-heading">编辑 Page</div>
<div class="panel-body">
@if (count($errors) > 0)
<div class="alert alert-danger">
<strong>Whoops!</strong> There were some problems with your input.<br><br>
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form action="{{ URL('admin/pages/'.$page->id) }}" method="POST">
<input name="_method" type="hidden" value="PUT">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="text" name="title" class="form-control" required="required" value="{{ $page->title }}">
<br>
<textarea name="body" rows="10" class="form-control" required="required">{{ $page->body }}</textarea>
<br>
<button class="btn btn-lg btn-info">新增 Page</button>
</form>
</div>
</div>
</div>
</div>
</div>
@endsection
