Warning Twig version 1.x is no longer maintained.
deprecated
1.36
The deprecated
tag was added in Twig 1.36.
Twig generates a deprecation notice (via a call to the trigger_error()
PHP function) where the deprecated
tag is used in a template:
1 2 3
{# base.twig #}
{% deprecated 'The "base.twig" template is deprecated, use "layout.twig" instead.' %}
{% extends 'layout.twig' %}
Also you can deprecate a block in the following way:
1 2 3 4 5 6 7 8
{% block hey %}
{% deprecated 'The "hey" block is deprecated, use "greet" instead.' %}
{{ block('greet') }}
{% endblock %}
{% block greet %}
Hey you!
{% endblock %}
Note that by default, the deprecation notices are silenced and never displayed nor logged. See Recipes to learn how to handle them.
