Display taxonomy term in Drupal Twig template translated
{#
/**
* @file
* Theme override to display a Talk node in Teaser view mode.
*
* The 'talk_category' variable was created in preprocess.
*/
#}
{# Other variables are excluded from this example to keep it simple. #}
{% include "@molecules/card/01-card.twig" with {
card_title: tt_category,
} %}
{#
It is a simple solution if there are not to much languages to support.
The example uses a component based aproach. Look for Emulsify theme for more info.
#}
{# Get the translated taxonomy term. #}
{% set pill_text_nl = node.field_talk_category.entity.translation('nl').name.value %}
{% set pill_text_fr = node.field_talk_category.entity.translation('fr').name.value %}
{# The next definition uses the Global variables module. #}
{% set current_lang = global_variables.current_langcode %}
{# Set the correct translation depending on the actually used language. #}
{% if current_lang == 'nl' %}
{% if pill_text_nl %}
{% set pill_text = pill_text_nl %}
{% endif %}
{% elseif current_lang == 'fr' %}
{% if pill_text_fr %}
{% set pill_text = pill_text_fr %}
{% endif %}
{% endif %}
{# Other variables are excluded from this example to keep it simple. #}
{% include "@pages/_page.twig" with {
hero_pill_text: pill_text,
} %}
