data_uri
The data_uri
filter generates a URL using the data scheme as defined in
RFC 2397:
1 2 3 4 5 6 7 8 9 10 11 12
{{ 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:
1
$ composer require twig/html-extra
Then, on Symfony projects, install the twig/extra-bundle
:
1
$ composer require twig/extra-bundle
Otherwise, add the extension explicitly on the Twig environment:
1 2 3 4
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.
