laravel模板引擎Blade

一、概述

Blade是Laravel提供的一个既简单又强大的模板引擎

和其他流行的PHP模板引擎不一样，Blade并不限制你在视图view中使用原生的PHP代码

所有的Blade视图页面都将被编译成原生的PHP代码并缓存起来，除非你的的模板文件修改，否则不会重新编译

模板继承：section,yield,extends,parent.

二、实例

1、定义布局模板 views/people/layout/layout.blade.php

 Laravel @yield('title')

     .body{margin:px;padding:px;}

     .header{width:100%;height:60px;background:red;margin-bottom:10px;}

     .sidebar{width:20%;height:500px;background:green;

         margin-right:20px;margin-bottom:10px;}

     .content{width:72%;height:500px;background:blue;margin-bottom:10px;}

     .footer{width:100%;height:60px;background:black}

     div{float:left;}

     @section('header')

     头部

     @show  

     @section('sidebar')

     侧边栏

     @show  

     @yield('content','主要内容区域')

     @section('footer')

     底部

     @show  

2、控制器方法分配数据

//模板技术

publicfunctionsection1(){

//.和/都可以

$name='helloiu';

$data=['sss','zzz'];

$students=Student::get();

returnview('people.student.section1',[

         'name'=>$name,

         'data'=>$data,

         'students'=>$students,

     ]);

}

publicfunctionurlTest(){

 return'urlTest';

}

3、子模板 views/people/student/section1.blade.php

@extends('people.layout.layout')

@section('header')

 @parent

 HEADER

@stop

@section('sidebar')

 sideBar

@stop

@section('content')

 Content    

 {{$name}}

 {{time()}}

 {{date('Y-m-d H:i:s',time())}}

 {{in_array($name,$data)?'true':'false'}}

 {{var_dump($data)}}

 {{isset($name)?$name:'default'}}

 {{$nameor'default'}}

 @{{$name}}

 {{-- 我是注释  --}}

 @include('people.common.common',['message'=>'我是error信息']);

 @if($name=='helloJiu')

     I'm {{$name}}

 @elseif($name == 'helloHu')

     I'm helloHu

 @else

     who am i?{{$name}}

 @endif

 @if(in_array($name,$data))

     true

 @else

     false

 @endif

 @unless($name=='helloJiu')

     I'm {{$name}}

 @endunless

 @for($i=0;$i

     {{ $i }}

 @endfor

 @foreach($students as $student)

     {{ $student->created_at }}

 @endforeach

 @forelse($students as $student)

     {{ $student->name }}

 @empty

     null

 @endforelse

 url

 urlAction

 route

@stop

4、people/common/common.blade.php

5、整个路由系统

Route::get('/',function(){

 returnview('welcome');

});

//路由群组

Route::group(['prefix'=>'people'],function(){

Route::get('member/index','People\MemberController@index');

Route::get('member/model','People\MemberController@model');

Route::get('student/index','People\StudentController@index');

Route::get('student/add','People\StudentController@insert');

Route::get('student/update','People\StudentController@update');

Route::get('student/select','People\StudentController@select');

Route::get('student/delete','People\StudentController@delete');

//查询构造器路由

Route::get('student/qbAdd','People\StudentController@qbAdd');

Route::get('student/qbUpdate','People\StudentController@qbUpdate');

Route::get('student/qbDelete','People\StudentController@qbDelete');

Route::get('student/qbSelect','People\StudentController@qbSelect');

Route::get('student/qbSelect','People\StudentController@qbSelect');

Route::get('student/qbSelectJH','People\StudentController@qbSelectJH');

//ORM路由

Route::get('student/ormIndex','People\StudentController@ormIndex');

Route::get('student/ormAddByAttr','People\StudentController@ormAddByAttr');

Route::get('student/ormAddByCreate','People\StudentController@ormAddByCreate');

Route::get('student/ormSelect','People\StudentController@ormSelect');

Route::get('student/ormUpdate','People\StudentController@ormUpdate');

Route::get('student/ormDelete','People\StudentController@ormDelete');

//模板路由

Route::get('student/section1','People\StudentController@section1');

Route::get('student/urlTest',[

     'as'=>'url',

     'uses'=>'People\StudentController@urlTest',

 ]);

Route::get('index',function(){

returnview('People.layout.layout');

 });

});

//路由中输出视图

Route::get('view',function(){

 returnview('welcome');

});

//绑定控制器MemberController::info()

Route::get('member/info','MemberController@info');

Route::any('member/info',[

 'uses'=>'MemberController@info',

 'as'=>'memberinfo',]

);

Route::any('getID/',['uses'=>'MemberController@getID'])

 ->where('id','[\d]*');

});
