HashidsBundle

Integrates hashids/hashids in a Symfony project.

Installation using composer

These commands requires you to have Composer installed globally.
Open a command console, enter your project directory and execute the following commands to download the latest stable version of this bundle:

Using Symfony Flex

    composer config extra.symfony.allow-contrib true
    composer req roukmoute/hashids-bundle

Using Symfony Framework only

    composer require roukmoute/hashids-bundle

If this has not been done automatically, enable the bundle by adding the following line in the config/bundles.php file of your project:

<?php

return [
    …,
    Roukmoute\HashidsBundle\RoukmouteHashidsBundle::class => ['all' => true],
];

Configuration

The configuration (config/packages/roukmoute_hashids.yaml) looks as follows :

roukmoute_hashids:

    # if set, the hashids will differ from everyone else's
    salt:            ""

    # if set, will generate minimum length for the id
    # 0 — meaning hashes will be the shortest possible length
    min_hash_length: 0

    # if set, will use only characters of alphabet string
    alphabet:        "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"

    # if set to true, it will continue with the next available param converters
    passthrough:     false

    # if set to true, it tries to convert all arguments passed to the controller
    auto_convert:    false

Usage

use Hashids\HashidsInterface;

public function postShow(HashidsInterface $hashids): Response
{
    $hashids->…
}

Next it's the same things of official documentation.

Hashids Converter

Converter Name: hashids.converter

The hashids converter attempts to convert any attribute set in the route into an integer parameter.

You could use hashid or id:

/**
 * @Route("/users/{hashid}")
 */
public function getAction(int $user)
{
}

or

/**
 * @Route("/users/{id}")
 */
public function getAction(int $user)
{
}

You could have several hashids in the same URL prefixed with _hash_.

/**
 * @Route("/users/{_hash_user}/status/{_hash_status}")
 */
public function getAction(int $user, int $status)
{
}

The keys must be the same as in parameters controller:

/**
 *                          _hash_user _hash_status
 *                                 ↕            ↕
 * public function getAction(int $user, int $status)
 */

You will receive a LogicException if a hash could not be decoded correctly.

Using auto_convert

auto_convert tries to convert all arguments in controller.

roukmoute_hashids:
  auto_convert: true

Base on the example above:

/**
 * @Route("/users/{user}/status/{status}")
 */
public function getAction(int $user, int $status)
{
}

It will not be possible to get an exception of type LogicException from the bundle if it is activated.

Using passthrough

passthrough allows to continue with the next available param converters.
So if you would like to retrieve an object instead of an integer, just active passthrough :

roukmoute_hashids:
    passthrough: true

Base on the example above:

/**
 * @Route("/users/{hashid}")
 */
public function getAction(User $user)
{
}

As you can see, the passthrough feature allows to use DoctrineParamConverter or any another ParamConverterInterface you would have created.

Twig Extension

Usage

{{ path('users.show', {'hashid': user.id | hashids_encode }) }}
{{ app.request.query.get('hashid') | hashids_decode }}
