Twig Components / Methods / block

Note: You are currently reading the documentation for Bolt 5.0. Looking for the documentation for Bolt 5.2 instead?

block is a Twig function to print a block multiple times when a template uses inheritance.

<title>{% block title %}{% endblock %}</title>

<h1>{{ block('title') }}</h1>

{% block body %}{% endblock %}

The block function can also be used to display one block from another template:

{{ block("title", "common_blocks.twig") }}

Use the defined test to check if a block exists in the context of the current template:

{% if block("footer") is defined %}
    ...
{% endif %}

{% if block("footer", "common_blocks.twig") is defined %}
    ...
{% endif %}
