How can I print current user role in Twig?

Question

I'm trying to get my user role thanks to a function in my theme.theme file.

function theme_get_user_role(){
  $current_user = \Drupal::currentUser();
  $roles = $current_user->getRoles();
}

then in my view :

{% set roles = theme_get_user_role() %}
{{ dump(roles) }}

But I have this error :

Twig_Error_Syntax : Unknown "theme_get_user_role" function. dans Twig_ExpressionParser->getFunctionNodeClass()

What do I miss ?

Answer 1

You can use below without any function. Because the User module provides the variable in preprocess for all templates: :

{% set roles = user.getroles(TRUE) %}
{{ dump(roles) }}

If you want to do anything only for the particular role then do this:

{% if 'ROLENAME' in user.getroles(TRUE)  %}
  <p>The user has the role "ABC".</p>
{% endif %}
