Sometimes it is necessary to get the actual value of a field (not the formatted/rendered one), e.g. to check a boolean for true or false.

If I want to get a field value of a node or paragraph inside twig templates (node.html.twig / paragraph.html.twig) I can use node.field_my_boolean.value respectively paragraph.field_my_boolean.value.

How do I accomplish this in a media twig template? I've already tried media.field_my_boolean.value but it does not work.

    try {{ content.field_my_boolean }} and you want the raw value without the HTML markup {{ content.field_my_boolean.0 }}

  • Both output the rendered value and not the actuall true/false. I can not use this because it is translated (e.g. "wahr"/"falsch" in German). Apr 20, 2017 at 10:37
  • When you do {{ content.field_my_boolean.0 }} is it showing wahr/flasch or 1/0 ?

  • It depends on the display format setting. If I set the formatter to 1/0 I get 1 or 0. If I set it to ``wahr/falsch` I get wahr or falsch. That's what I mean by "rendered value". Apr 20, 2017 at 11:08

Right now, the Media module does not pass its object in the variables like Paragraphs and Node does. This is why media.field_my_boolean.value does nothing.

You can correct this in your theme by implementing theme_preprocess_media, which adds the media object to the variables:

/**
 * Prepares variables for media templates.
 *
 * Default template: media.html.twig.
 *
 * @param array $variables
 *   An associative array containing:
 *   - media: An individual media for display.
 */
function mytheme_preprocess_media(&$variables) {
  $variables['media'] = $variables['elements']['#media'];
}

You can then access media. in your twig template and any connected fields on it just like Paragraph or Node.

  • You seem to be right. Actually function mytheme_preprocess_media(&$variables) {$variables['media'] = $variables['elements']['#media']} should be enough because your themes preprocess function is just adding variables. No need to copy the whole function from media module. Apr 20, 2017 at 12:16
  • Gotcha - for some reason I had to use the whole function, could be an earlier build.

  • OK, I'm referring to Drupal 8.3.0 and Media Entity 8.x-1.6. Just update your answer and I will accept it. Apr 20, 2017 at 13:39

You can with {{ content.field_my_boolean }} and if you want the raw value without the HTML markup use content.field_my_boolean.0

Both output the rendered value and not the actuall true/false. I can not use this because it is translated (e.g. "wahr"/"falsch" in German).

Then use the |t function and do this

{% if content.field_my_boolean.0 == 'Wahr'|t %}
    // do something
{% elseif content.field_my_boolean.0 == 'Falsch'|t %}
    // do something
{% endif %}
