Laravel 九淺一深

LARAVEL 九淺⼀一深 JohnsonLu

九淺⼀一深 • Installation • Install • Route • Blade(View)
• Controller • Artisan • Autoload • Session • Input • Eloquent ORM 2

Introduction 3

Laravel Framework • Trademark of Taylor Otwell • Use Symfony
Component • Like Ruby on Rails 、 ASP.NET MVC • Version 4.2 4

優點 • 優雅 • 快樂 • 潮 5

優點 • Authentication • Routing • Session • Cache •
Migration • IoC Container 6

Installation 7

Composer Install composer create-project laravel/laravel <project> -- prefer-dist 8

⺫⽬目錄 • app/conﬁg/app.php • 紀錄debug、url、timezone、key • app/storage • 暫存檔⺫⽬目錄 •
app/routes.php • 控制 Route 的檔案 • app/ﬁlters.php • 控制 Route Filter 檔案 9

⺫⽬目錄 • app/controllers • Controller ⺫⽬目錄 • app/view • View
⺫⽬目錄 • bootstrap/paths.php • 設定基本⺫⽬目錄路徑的檔案(app,public…etc) ! 10

設定 • chmod -R 777 app/storage • public/.htaccess • RewriteRule
^(.+)$ /index.php [L] 11

Route 12

Default Route • app/routes.php ! ! // Demo 1 Route::get('demo1',
function() { return 'Hello World'; }); 13

POST • app/routes.php ! ! // Demo 2 Route::post('demo2', function()
{ return 'Hello World'; }); ! 14

Match HTTP Verbs • app/routes.php ! ! // Demo 3
Route::match(array('GET', 'POST'), 'demo3', function() { return 'Hello World'; }); ! 15

Use https • app/routes.php ! ! // Demo 4 Route::get('demo4',
array('https', function() { return 'Must be over HTTPS'; })); ! 16

Parameters • app/routes.php ! // Demo 5 Route::get('demo5/{id}', function($id) {
return 'No.' . intval($id); }); ! 17

Route Filters • app/routes.php or app/filters.php ! // Demo 6
Route::filter('old', function() { if (Input::get('age') < 30) { return 'Go back to my home'; } }); ! Route::get('demo6', array('before' => 'old', function() { return 'Too old'; })); ! 18

Blade 19

Blade • Blade 就是 Laravel 提供的 Template Engine • 在
Laravel 中，使⽤用 Blade 時必須在 View 的檔名加上 blade.php 20

Blade • app/views • ├── hello.php • ├── includes •
│ └── header.blade.php • ├── layouts • │ └── default.blade.php • └── pages • ├── demo7.blade.php • └── home.blade.php 21

Blade 參數 • app/routes.php ! // Demo 7 Route::get('demo7', function()
{ return View::make('pages.demo7', array('name' => 'Johnson')); }); ! 22

Blade 參數 • app/view/pages/demo8.blade.php <!DOCTYPE HTML> <html> <head>  @include('includes.header') </head> <body>  !  {{{ $name or 'Default' }}} !  @{{ not execute }} !  Hello, {{ $name }} </body> </html> ! 23

Blade 連續技 • app/routes.php ! // Demo 8 Route::get('demo8', function()
{ return View::make('pages.home'); }); ! ! 24

Blade 連續技 • app/view/includes/header.blade.php  <meta charset="utf-8">
<meta name="description" content="This is Test Layout"> <meta name="author" content="Johnson"> ! <title>Test Layout</title> 25

Blade 連續技 • app/view/layouts/default.blade.php <!DOCTYPE HTML> 
<html> <head>  @include('includes.header') </head> <body> <div class="content">  @yield('content') </div> </body> </html> ! 26

Blade 連續技 • app/view/pages/home.blade.php {{-- Demo 8 --}} {{-- Use
Default Layout --}} @extends('layouts.default') ! {{-- Render content --}} @section('content') i am the home page @stop ! ! 27

Controller 28

Basic Controller • app/routes.php ! // Demo 9 Route::get('demo9', 'Demo9Controller@sayHello');
! 29

Basic Controller • app/controllers/Demo9Controller.php class Demo9Controller extends BaseController { //
Demo 9 public function sayHello() { return View::make('hello'); } } ! ! 30

RESTful Controllers • app/routes.php ! // Demo 10 Route::Controller('demo10', 'Demo10Controller');
! 31

RESTful Controllers • app/controllers/Demo10Controller.php class Demo10Controller extends BaseController { //
Demo 10 public function getIndex() { return "Hello"; } ! public function postProfile() { return 'Profile'; } ! // Any Http Verbs public function anyLogin() { return 'Login'; } ! public function getAdminProfile() { return 'demo10/admin-profile'; } } ! 32

Controller Filter ! class UsersController extends BaseController { public function
__construct() { // Filter use auth except getLogin $this->beforeFilter('auth', array('except' => 'getLogin')); ! // Filter use csrf on post $this->beforeFilter('csrf', array('on' => 'post')); ! // Filter only foo,bar action $this->afterFilter('log', array('only' => array('fooAction', 'barAction'))); ! // After Filter $this->afterFilter(function() { echo "After"; }); } } ! 33

Controller Filter • app/controllers/Demo11Controller.php ! class Demo11Controller extends BaseController {
// Demo 11 public function __construct() { $this->beforeFilter('@filterRequests'); } ! public function index(){} ! public function filterRequests($route, $request) { echo 'Filter'; } } ! 34

Artisan 35

Artisan • Laravel CLI • ⼟土炮⼯工具幫⼿手 ! 36

Artisan • # 查看可以使⽤用的指令清單 • php artisan list ! •
# 指令參數查詢 (指令前⾯面加上help) • php artisan help migrate ! • # 查詢 Laravel 版本 • php artisan --version 37

Artisan • # 建⽴立 Resource Controller • php artisan controller:make
PhotoController ! • # 條件判斷，只建⽴立index, show • php artisan controller:make PhotoController --only=index,show ! • # 條件判斷，除了index以外全部建⽴立 • php artisan controller:make PhotoController --except=index 38

Autoload 39

Autoload • composer.json "autoload": { "classmap": [ "app/commands", "app/controllers", "app/models",
"app/database/migrations", "app/database/seeds", "app/tests/TestCase.php" ], "psr-0": { "KK": "app/lib/kklibs" } } 40

Autoload • Update autoload conﬁg composer dump-autoload ! ! !
! 41

Session 42

Session ! // put session(key, value) Session::put('name', 'Johnson'); ! //
get session $value = Session::get('name'); ! // getAll session $data = Session::all(); ! // default value $value = Session::get('name', 'default'); 43

Session ! // push array Session::push('user.teams', 'developers'); $value = Session::get('user');
echo $value['teams'][0]; ! // isset if (Session::has('name')) { echo 'Have'; } ! // release session Session::forget('key'); ! // release all session Session::flush(); ! 44

Input 45

Input ! // get name $name = Input::get('name'); ! //
default value $name = Input::get('name', 'Johnson'); ! // isset if (Input::has('name')) {} ! // getAll $input = Input::all(); ! // get name, password $input = Input::only('name', 'password'); ! // except name $input = Input::except('name'); 46

Eloquent ORM 47

Eloquent ORM • 1.DB Conﬁg • app/conﬁg/database.php ! ! !
48

Eloquent ORM • app/models/Member.php ! class Member extends Eloquent {
protected $table = 'member'; protected $primaryKey = 'account'; } ! 49

Eloquent ORM • Eloquent 預設的資料表名稱會去抓取class名稱⼩小寫的複數單字 • 以Member為例，會去抓取’members’ • 預設的
primaryKey會去抓取 ‘id’ 這個欄位 50

Eloquent ORM • app/models/Member.php ! class Member extends Eloquent {
protected $table = 'member'; protected $primaryKey = 'account'; public $timestamps = false; } 51

Eloquent ORM • Elquent 預設在新增修改時會更動updated_at和 created_at兩個欄位。如果要省略這兩個欄位必須在Model中調整timestamps ! 52
