twig_reflection

Objectives

This Twig extension allows to access public static attributes and methods of a class.

Installation

1. Copy the file Reflection.php in the Twig/Extension directory of your Bundle/Module.
2. Declare the extension. For example in Symfony 2/3, you have to do it in the app/config/services.yml :

site.twig.reflectionExtension:
        class: AppBundle\Twig\Extension\Reflection
        tags:
            - { name: twig.extension } 

Utilization

There are two methods callable in this extension :

* callStaticMethod($className, $methodName, array $args = [])

* getStaticAttribute($className, $attributeName)

From your Twig template, just call the good one with the proper parameters, for example:

set arrType = getStaticAttribute('AppBundle\\Entity\\Book', 'arrSearchTypes')
