| ``data_uri`` |
| ============ |
| |
| The ``data_uri`` filter generates a URL using the data scheme as defined in |
| `RFC 2397`_: |
| |
| .. code-block:: html+twig |
| |
| {{ image_data|data_uri }} |
| |
| {{ source('path_to_image')|data_uri }} |
| |
| {# force the mime type, disable the guessing of the mime type #} |
| {{ image_data|data_uri(mime="image/svg") }} |
| |
| {# also works with plain text #} |
| {{ '<b>foobar</b>'|data_uri(mime="text/html") }} |
| |
| {# add some extra parameters #} |
| {{ '<b>foobar</b>'|data_uri(mime="text/html", parameters={charset: "ascii"}) }} |
| |
| .. note:: |
| |
| The ``data_uri`` filter 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()); |
| |
| .. note:: |
| |
| The filter does not perform any length validation on purpose (limit depends |
| on the usage context), validation should be done before calling this filter. |
| |
