``constant`` | |
============ | |
``constant`` checks if a variable has the exact same value as a constant. You | |
can use either global constants or class constants: | |
.. code-block:: twig | |
{% if post.status is constant('Post::PUBLISHED') %} | |
the status attribute is exactly the same as Post::PUBLISHED | |
{% endif %} | |
You can test constants from object instances as well: | |
.. code-block:: twig | |
{% if post.status is constant('PUBLISHED', post) %} | |
the status attribute is exactly the same as Post::PUBLISHED | |
{% endif %} |
