Build Status Scrutinizer Code Quality

Are you often tired to repeat static choices like gender or civility in your apps ?

Notice: This bundle is a fork from KnpLabs/DictionaryBundle. We are working on releasing a 3.0 version but for now the released version is 2.x. You should refere to the right branch to have a good documentation.


  • Symfony >= 3.4
  • PHP >= 7.1


Add the DictionaryBundle to your composer.json:

    "require": {
        "biig/dictionary-bundle": "^3.0"

Or install it directly with composer command

composer require biig/dictionary-bundle

Register the bundle in app/AppKernel.php

$bundles = array(
    // ...
    new Knp\DictionaryBundle\KnpDictionaryBundle(),

Basic usage

Define dictionaries in your config.yaml file:

        my_dictionary:      # your dictionary name
            - Foo           # your dictionary content
            - Bar
            - Baz

You will be able to retrieve it through the dictionary registry service:


Dictionary form type

Now, use them in your forms:

use Knp\DictionaryBundle\Form\Type\DictionaryType;

public function buildForm(FormBuilderInterface $builder, array $options)
        ->add('civility', DictionaryType::class, [
            'name' => 'my_dictionary'

The dictionary form type extends the symfony's choice type and its options.

Validation constraint

You can also use the constraint for validation. The value have to be set.

use Knp\DictionaryBundle\Validator\Constraints\Dictionary;

class User
     * @ORM\Column
     * @Dictionary(name="my_dictionary", multiple=false)
    private $civility;

Advanced usage

You can specify the indexation mode of each dictionary

        my_dictionary:                  # your dictionary name
            type: 'key_value'           # your dictionary type
            content:                    # your dictionary content
                "foo": "foo_value"
                "bar": "bar_value"
                "baz": "baz_value"

Available types

  • value (default) : Natural indexation
  • value_as_key: Keys are defined from their value
  • key_value: Define your own keys
  • callable: Build a dictionary from a callable

Callable dictionary

You can create a callable dictionary:

        my_callable_dictionary:         # your dictionary name
            type: 'callable'            # your dictionary type
            service: ''   # a valid service from your application
            method: 'getSomething'      # the method name to execute

Callable dictionaries are loaded with a lazy strategy. It means that the callable will not be called if you do not use the dictionary.

Categories in dictionaries

If you want to retrieve some groups of dictionaries from the registry, then you can specify a category to your dictionary.

        my_dictionary:                  # your dictionary name
            type: 'key_value'           # your dictionary type
            category: 'product.toy'     # your dictionary category
            content:                    # your dictionary content
                foo: foo_value
                bar: bar_value
                baz: baz_value

Get a registry for this category later:

// Retrieve all dictionaries of a special category
$dictionaries = $registry->filterByCategory('product.toy')->all();


For now, this bundle is only able to resolve your class constants:

    - MyClass::MY_CONSTANT
    - Foo
    - Bar

You want to add other kinds of transformations for your dictionary values ? Feel free to create your own transformer !

Add your own transformers

Create your class that implements TransformerInterface. Load your transformer and tag it as knp_dictionary.value_transformer.

    	class: %my_transformer_class%
        	- { name: knp_dictionary.value_transformer }

Use your dictionary in twig

You can also use your dictionary in your Twig templates via calling dictionary function (or filter)

{% for example in dictionary('examples') %}
    {{ example }}
{% endfor %}

But you can also access directly to a value by using the same function (or filter)

{{ 'my_key'|dictionary('dictionary_name') }}

Faker provider

The KnpDictionaryBundle comes with a faker provider that can be used to provide a random entry from a dictionary.


To register the provider in nelmio/alice, you can follow the official documentation

or ...

if you use the awesome knplabs/rad-fixtures-load library, the dictionary provider will be automaticaly loaded for you :)

        firstname: John
        latnale: Doe
        city: <dictionary('cities')>

Use dictionary command

You can use the following command to show your app dictionaries easily:

php bin/console knp:dictionary:dump

If you want to display only one dictionary, you can set it name in argument

php bin/console knp:dictionary:dump my_dictionary

Create your own dictionary implementation


Your dictionary implementation must implements the interface Dictionary. In Symfony >= 3.3, your class will be automatically register as dictionary service.

Dictionary Factory

You must create a dictionary factory that will be responsible to instanciate your dictionary.

    # Syntax Symfony >= 3.3
            { name: 'knp_dictionary.factory' }
