| ``block`` |
| ========= |
| |
| When a template uses inheritance and if you want to print 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.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.twig") is defined %} |
| ... |
| {% endif %} |
| |
