# `block`

When a template uses inheritance and if you want to print a block multiple times, use the `block` function:

    <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 %}
