Command list

php artisan list

Every command has a description, defined inputs, etc.

Database

Schema Builder

Schema::create('posts', function($table) {  $table->increments('id');
  $table->string('title');  $table->string('tagline', 64); // constraint as second argument  $table->text('body');
  $table->integer('category_id')        ->unsigned()  // chain methods for other options        ->nullable(); // for optional fields
  $table->softDeletes();  $table->timestamps();});

Migrations

database version control

prefixed with timestamp

ordered alphabetically

good for teams / feature branching in git

seeding

Fills the database with sample data

Brilliant for development

Even better for Acceptance Testing

Eloquent

works with MySQL, PostgreSQL, SQLite, SQL Server

class Company extends Eloquent {}
$company = Company::create(array(
           'address' => '155 Harbor Blvd',
           'city' => 'Fullerton'
));
$company = Company::find(1);

echo $company->address; // 155 Harbor Blvd 
$company = Company::where('city', "Fullerton")->first();
$companies = Company::orderBy('city', 'desc')->take(10)->get();
       Pagination built in! Example:
$companies = Company::orderBy('city', 'desc')->paginate(10);

Chainable Relationships

function comments(){  return $this->hasMany('Comment');}

$post->comments()->where('user_id', $user->id)->get();

Dynamic properties:

$post->comments;

RELATIONSHIPS

One to One

class Company extends Eloquent {
     public function salesperson()
     {
          return $this->hasOne('Salesperson');
     }
}
$salesperson = Company::find(1)->salesperson->name;

Many to One

class Company extends Eloquent {
     public function customers()
     {
          return $this->hasMany('Customer');
     }
}
$customers = Company::find(1)->customers;

Many to Many + Polymorphic

Eager Loading

function friends(){  return $this->belongsToMany('User');}

User::with('friends')->get();

Blade

SYNTAX

PHP

<a href="<?php echo $post->link; ?>">  <?php echo $post->title; ?></a>

Blade

<a href="{{ $post->link }}">  {{ $post->title }}</a>

BLADE

Control Statements

@if( $a > 3 )  {{ $a }}
@endif
@foreach ($users as $user)
    <p>This is user {{ $user->id }}</p>
@endforeach

Partials

@section('content')
    <p>This is my body content.</p>
@stop

@yield('content')

helper

Form::open();

Form::text('username');
Form::password('password');
Form::checkbox('name', 'value', true);
Form::file('image');
Form::select('size', array('L' => 'Large', 'S' => 'Small'));

Form::submit('Click Me!');

Form::close();

Routing

Routes

Route::get('/posts/{post}', function($post){  return "Post title: $post!";});

Passing parameters

Route Constraints

Route::get('user/{id}/{name}', function($id, $name)
{
    //
})
->where(array('id' => '[0-9]+', 'name' => '[a-z]+'))

Controllers

Route::get('home', ['as' => 'home', 'uses' => 'SiteController@index']);

Route::controller('/', 'SiteController');

/* In SiteController.php */public function getIndex() { return ''; } 
public function postIndex() { return ''; }

Resource Controllers

Route::resource('post', 'PostController');

Filters

Route::get('create', array('before' => 'auth|csrf', function()
{
    //
}));

Route Groups

Route::group(['prefix' => 'post'], function() {  Route::get('{post-slug}', function($post) { return 'the post'; });
  Route::get('{post-slug}/edit', function($post) { return 'edit post'; });
  Route::post('{post-slug}/edit', function($post) {    // Validate    // Save    return Redirect::route('blog.post');  });
});

Named Routes

Route::get('posts', ['as' => 'posts.list', function(){  return 'list of posts';}]);

Redirect::route('posts.list);

URL::route('posts.list');

URL::route('posts.show', ['post-slug' => $post->slug]);

Security

User logins, auth checks, secure hashing, password resets

all built in.

Authentication

$credentials = array(
  'username' => 'example@gmail.com', 
  'password' => 'secret'
);

if (Auth::attempt($credentials))
{
     return Redirect::to('user/profile');
}
Get user's info : 
$email = Auth::user()->email;

Logout:
Auth::logout();

input

Session

cookie

Easy to manage, easy to use

example

$name = Input::get('name', 'Sally');
$input = Input::only('username', 'password');
$input = Input::except('credit_card');
$input = Input::get('products.0.name');

Session::put('key', 'value');
Session::flash('key', 'value'); 
$value = Session::get('key');
Session::forget('key');
Session::flush(); 
$value = Cookie::get('name');
$cookie = Cookie::forever('name', 'value');

Validation

$input = Input::all();

$rules = array(
	'name' => 'required|min:3|max:32|alpha',
	'age'  => 'required|integer',
        'image'=> 'image|max:1500',
        'password' => 'confirmed'
);

$v = Validator::make($input, $rules);

if( $v->fails() ){
	// code for validation failure :(
}else{
	// code for validation success!
}

+ 14 more types(including RegEx)

Environments

bootstrap/start.php

$env = $app->detectEnvironment(array(
    'local'      => array('http://localhost*', '*.dev'),
    'test'    => array('http://test.mywebsite.com*'),
    'production' => array('http://mywebsite.com*'),
));

add environment config files under app/config

app
  - config
     - test
        - database.php
        - session.php
     - production
        - database.php
...

Testing

Support for PHPUnit out of the box

Unit Testing

IOC Container

Dependancy Injection

Mockery

Example of a test:

$response = $this->call('GET', 'user/profile');

DOM crawler:

$this->assertCount(1, $crawler->filter('h1:contains("Hello World!")'));
