README

This Bundle provides translator service, translator twig filter and form type for consistence/consistence enums.

Installation

Applications that use Symfony Flex

Open a command console, enter your project directory and execute:

$ composer require mhujer/consistence-bundle

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require mhujer/consistence-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    Mhujer\ConsistenceBundle\MhujerConsistenceBundle::class => ['all' => true],
];

Usage

Examples consider having the following enum:

<?php declare(strict_types = 1);

namespace App\Card;

final class CardColor extends \Consistence\Enum\Enum
{

    public const BLACK = 'black';
    public const RED = 'red';

}

Translation file

The translator automatically converts an instance of enum to a translation key consisting of FQCN of the enum, colon and its value, e.g.:

App\Card\CardColor:red

Best approach is to create a translation file using the PHP format (enums.en.php) which allows you to use the class name:

<?php declare(strict_types = 1);

use App\Card\CardColor;

return [
    CardColor::class . ':' . CardColor::RED => 'red',
    CardColor::class . ':' . CardColor::BLACK => 'black',
];

As you might have noticed, the translation domain is set to enums.

Twig

In Twig templates you can use transEnum filter to convert an enum to a translated string:

{{ variableContainingEnum | transEnum }}

Translation domain

Sometimes it is useful to have different translations for the same enum (e.g. when the enum is used in admin and frontend UI). This is achieved by an translationDomain parameter which can be passed to transEnum:

{{ variableContainingEnum | transEnum('enums-frontend') }}

It loads translations transparently from another domain using Symfony translator:

// enums-frontend.en.php
<?php declare(strict_types = 1);

use App\Card\CardColor;

return [
    CardColor::class . ':' . CardColor::RED => 'Red',
    CardColor::class . ':' . CardColor::BLACK => 'Black',
];

Forms

In forms, you can use EnumType as a field type. You need to set an option enum_class to an enum class:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('cardColor', EnumType::class, [
            'enum_class' => CardColor::class,
            'label' => 'Card Color',
        ])
    //...

Property in your request object should look like this (it contains an instance of CardColor):

/**
 * @Assert\NotBlank()
 * @var \App\Card\CardColor
 */
public $cardColor;

Requirements

Works with PHP 7.4 or higher and Symfony 5.4 or higher.
