block  New in version 1.28: Using block with the defined test was added in Twig 1.28.   New in version 1.28: Support for the template argument was added in Twig 1.28.  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 %}
