blockΒΆ

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

1
2
3
4
5
<title>{% block title %}{% endblock %}</title>

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

{% block body %}{% endblock %}

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

1
{{ block("title", "common_blocks.twig") }}

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

1
2
3
4
5
6
7
{% if block("footer") is defined %}
    ...
{% endif %}

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