``html_classes``
================
.. versionadded:: 2.12
The ``html_classes`` function was added in Twig 2.12.
The ``html_classes`` function returns a string by conditionally joining class
names together:
.. code-block:: html+twig
<p class="{{ html_classes('a-class', 'another-class', {
'errored': object.errored,
'finished': object.finished,
'pending': object.pending,
}) }}">How are you doing?</p>
.. note::
The ``html_classes`` function is part of the ``HtmlExtension`` which is not
installed by default. Install it first:
.. code-block:: bash
$ composer require twig/html-extra
Then, use the ``twig/extra-bundle`` on Symfony projects or add the extension
explicitly on the Twig environment::
use Twig\Extra\Html\HtmlExtension;
$twig = new \Twig\Environment(...);
$twig->addExtension(new HtmlExtension());
