Symfony CMF Slugifier API

This package is part of the Symfony Content Management Framework (CMF) and licensed under the MIT License.

A "slugifier" is a function which transforms a string such as this into a URL-friendly string such-as-this. Slugifiers are also known as "urlizers".

This package does not contain a slugifier implementation, it provides a standard interface (SlugifierInterface) for use by third party slugifiers and a CallbackSlugifier that is capable of wrapping most non-implementing third-party slugifiers to the SlugifierInterface.

Requirements

• See also the require section of composer.json

Documentation

Perhaps the best way to document this simple component is with a demonstration. You have an event subscriber which slugifies the title of a blog post:

<?php

use Symfony\Cmf\Api\Slugifier\SlugifierInterface;

class FooSubscriber
{
    private $slugifier;

    public function __construct(SlugifierInterface $slugifier)
    {
        $this->slugifier = $slugifier;
    }

    public function onEntitySave(\Some\Event $event)
    {
         $entity = $event->getEntity();
         $entity->setSlug($this->slugifier->slugify($entity->getTitle());
    }
}

You can then inject either a slugifier which already implements the CMF SlugifierInterface or you can use non-implementing libraries using the CallbackSlugifier. Using non-implementing libraries is very easy, assume you want to use the aferrandini/urlizer package (which is also used by the RoutingAutoBundle), you can configure the CallbackSlugifier object to call the Ferrandini\Urlizer::urlize() method:

$slugifier = new CallbackSlugifier('Ferrandini\Urlizer::urlize');
$fooSubscriber = new FooSubscriber($slugifier);

By using the Slugifier package you decouple your application from the slugifier implementation.

FIG Proposal

We proposed this to FIG but unfortunately the proposal did not get enough interest. We would still be happy to contribute this to a PSR should the interest come up and deprecate this package in favor of the PSR one.
