Slug is a component which generates slugs easily whatever persistence mecanism you use (Propel2, Doctrine2, custom ORM...).

To generate a slug of a string there is always two 2 steps:

• The transliteration step which converts a given string from any writing system (French, Deutsh, Greek, Arabic...) into its ASCII representation.
• The slug generation step which basically separates each word and field by a custom delimiter.

Therefore Slug component has 2 services: TransliteratorInterface and SlugGeneratorInterface. Each of these services can have multiple implementations:

• LatinTransliterator: Transliterate a string written in any Latin alphabet (French, Deutsh, Spanish...) into its ASCII equivalent.
• DefaultSlugGenerator: Customize the word and field separator.
• PatternSlugGenerator: Complete customization of slug generation.

Installation

Using Composer, just require the ddd/components package:

{
    "require": {
        "ddd/components": "dev-master"
    }
}

Usage

To be able to slugify an entity or model, you just have to implement the SluggableInterface:

<?php

use Ddd\Slug\Model\SluggableInterface;
use Ddd\Slug\Service\SlugGeneratorInterface;

class Article implements SluggableInterface
{
    private $createdAt;
    private $title;
    private $slug;

    public function slugify(SlugGeneratorInterface $slugifier)
    {
        $this->slug = $slugifier->slugify(array($this->createdAt->format('Y'), $this->title));
    }

    // other methods...
}

Then you just have to call the slugify method to generate the slug:

use Ddd\Slug\Infra\SlugGenerator\DefaultSlugGenerator;
use Ddd\Slug\Infra\Transliterator\LatinTransliterator;

$article = new Article();
$article->setTitle('Hello world!');
$article->slugify(new DefaultSlugGenerator(array(new LatinTransliterator())));

echo $article->getSlug(); // writes "2013-hello-world"
