``enum``
|
|
========
|
|
|
|
``enum`` gives access to enums:
|
|
|
|
.. code-block:: twig
|
|
|
|
{# display one specific case of a backed enum #}
|
|
{{ enum('App\\CardSuite').Clubs.value }} {# "clubs" #}
|
|
|
|
{# display one specific case of a backed enum, with a dynamic name #}
|
|
{% set case_name = 'Spades' %}
|
|
{{ enum('App\\CardSuite').(case_name).name }} {# "Spades" #}
|
|
|
|
{# get all cases of an enum #}
|
|
{% for case in enum('App\\CardSuite').cases %}
|
|
{{ case.value }}
|
|
{% endfor %}
|
|
{# "clubs", "spades", "hearts", "diamonds" #}
|
|
|
|
{# get a specific case of an enum by value #}
|
|
{% set card_suite = enum('App\\CardSuite').from('hearts') %}
|
|
{{ card_suite.name }} {# "Hearts" #}
|
|
{{ card_suite.value }} {# "hearts" #}
|
|
|
|
{# call any methods of the enum class #}
|
|
{{ enum('App\\CardSuite').someMethod() }}
|
|
|
|
When using a string literal for the ``enum`` argument, it will be validated
|
|
during compile time to be a valid enum name.
