3. Usage

Inject SonataFormatterBundleFormatterPool` in your class:

assert($formatterPool instanceof Pool::class);

$html = $formatterPool->transform('rawhtml', $text);

in a template:

{{ my_data|format_text('rawhtml') }}

3.1. Form

The bundle provides a widget to format a text when the form is bound. You have to declare 2 fields:

  • source content field;

  • formatter field.

And initialize a form type:

use Sonata\FormatterBundle\Form\Type\FormatterType;

    ->add('rawContent') // source content
    ->add('contentFormatter', FormatterType::class, [
        'source_field' => 'rawContent',
        'target_field' => 'content',

When data is populated, the content property will be populated with the text transformed from the selected transformer name and the rawContent property.

This can be used to pregenerate the content of a markdown blog post, for instance.

3.2. Twig Formatter

TwigFormatter uses the Twig\Environment of the project (registered within service container as twig). All settings that affect the Twig\Environment of the project (like the template loader in use, enabled extensions etc.) will also affect the TwigFormatter.

Also, TwigFormatter cannot have extensions enabled.

3.2.1. Security warning

Since in most cases TwigFormatter will be used as the formatter in the administration interface (like the one shown above with the form), be careful of allowing users to edit the templates, as this could potentially affect the safety of the system. You have to take care of the safety of your templates. In exceptional cases, you can create a separate instance of Twig\Environment, register it within the service container and override TwigFormatter definition passing own secure Twig Environment as a parameter instead of the project one.
