Laravel Util

Laravel Util provides some useful method, such like enum and presenter

Installation

To get the latest version, simply require the project using Composer:

$ composer require orbas/util

and register the Orbas\Util\ServiceProvider::class service provider in your config/app.php

Enum

A enum is a distinct type that consists of a set of named constants called the enumerator list.

You can use it in a easier way to make your own enum.

Create a enum class

$ php artisan util:make:enum Gender

That will create a class to app/Enums/ folder

Define the enum

namespace App\Enums;

use Orbas\Util\Enum\Enumable;

class Gender implements Enumable
{
    /**
     *
     * @return array
     */
    public function create()
    {
        return ['female', 'male'];
    }
}

or you can define the key

namespace App\Enums;

use Orbas\Util\Enum\Enumable;

class Weekday implements Enumable
{
    /**
     *
     * @return array
     */
    public function create()
    {
        return [
            1 => 'Monday',
            2 => 'Tuesday',
            3 => 'Wednesday',
            4 => 'Thursday',
            5 => 'Friday',
            6 => 'Saturday',
            7 => 'Sunday'
        ];
    }
}

Enjoy using it

Generate a collection of gender

app('enum')->create('gender');

Get value from key

app('enum')->value(1, 'weekday'); // this will echo Monday  

Use Facade

Add class aliases to the aliases array of config/app.php:

  'aliases' => [
    // ...
      'Enum' => \Orbas\Util\Facades\Enum::class,
    // ...
  ],

then you can use it like this

// equal to app('enum')->create('gender');
Enum::create('gender');
Enum::gender();

More functionality will be released in the future.

Presenter

or you can call it view presenter. Sometimes you have some logic need to be performed before you put the data.

for example

{{ $user->first_name }} {{ $user->last_name }}
{{ $user->gender == 0 ? 'female' : 'male' }}
{{ Carbon\Carbon::parse($user->birthday->format('d/m/Y') }}

A presenter is a pattern that you can put the logic far from view and model. (keep model clean, and do what it should do.)

Create a presenter class

$ php artisan util:make:presenter User

That will create a class to app/Presenters folder

Edit your presenter logic

namespace App\Presenters;

use Orbas\Util\Presenter;

class User extends Presenter
{
    public function full_name()
    {
        return $this->attribute('first_name') . ' ' . $this->last_name;
    }
    
    public function birthday()
    {
        return Carbon\Carbon::parse($this->attribute('')
    }
}

Put present trait to your model

namespace App;

use Illuminate\Database\Eloquent\Model;
use Orbas\Util\Traits\Presenter;

class User extends Model
{
    use Presenter;   
}

Usage

$user = App\User::find(1);

$user->present()->full_name;

// or
$user->present('full_name');

Multi-language with Enum

Presenter provides auto translation.

Put enums.php to resources/lang/YOUR_LOCALE/enums.php

// resources/lang/zh-TW/enums.php
return [
    'gender' => [    // enum name
        'female' => '女',    // enum key => translation word
        'male'   => '男'
    ]
];

Presenter will translate for you

$user = App\User::first();
$user->present('gender');
// or
$user->present()->gender;

//or given a enum name and locale
$user->present()->enum('gender', 'Gender', 'zh-TW');
