| ``html_classes`` |
| ================ |
| |
| 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, on Symfony projects, install the ``twig/extra-bundle``: |
| |
| .. code-block:: bash |
| |
| $ composer require twig/extra-bundle |
| |
| Otherwise, add the extension explicitly on the Twig environment:: |
| |
| use Twig\Extra\Html\HtmlExtension; |
| |
| $twig = new \Twig\Environment(...); |
| $twig->addExtension(new HtmlExtension()); |
