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 4 Framework

    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

Usage

$hashids = $this->get('hashids');

Next it's the same things of official documentation.

Other Features

The Roukmoute\HashidsBundle\Hashids has extra features:

$minHashLength = 42;

// Edit the minimum hash length.
$this->get('hashids')->setMinHashLength($minHashLength)->encode(1, 2, 3);

// Encode with a custom minimum hash length.
$this->get('hashids')->encodeWithCustomHashLength($minHashLength, 1, 2, 3);

Hashids Converter

Converter Name: hashids.converter

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

You could use hashid or id to add :

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

or

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

For specific case, just add "hashid" = "{parameter_name}" in ParamConverter
options:

/**
 * @Route("/users/{slug}")
 *
 * @ParamConverter("user", class="RoukmouteBundle\Entity\User", options={"hashid" = "user"})
 */
public function getAction(int $user)
{
}

You could have several hashids one the same URL:

/**
 * @Route("/users/{user}/status/{status}")
 *
 * @ParamConverter("user", class="RoukmouteBundle\Entity\User", options={"hashid" = "user"})
 * @ParamConverter("status", class="RoukmouteBundle\Entity\Notification", options={"hashid" = "status"})
 */
public function getAction(int $user, int $status)
{
}

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 ParamConverter you would have created.

Twig Extension

Usage

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