``block``
=========
When a template uses inheritance and if you want to render a block multiple
times, use the ``block`` function:
.. code-block:: html+twig
<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:
.. code-block:: twig
{{ block("title", "common_blocks.html.twig") }}
Use the ``defined`` test to check if a block exists in the context of the
current template:
.. code-block:: twig
{% if block("footer") is defined %}
...
{% endif %}
{% if block("footer", "common_blocks.html.twig") is defined %}
...
{% endif %}
Arguments
---------
* ``name``: The block name
* ``template``: The template where to look for the block
