I have a File entity loaded programmatically. I want to load a Media entity from it. Is there a way to achieve this?

  • Do you mean you want to load the Media entity the File entity belongs to? Or you want to create a new Media entity and add the File entity you've created to that File entity?

  • Yes exactly i want to load the Media entity the File belongs to.

Example - if your File entity is loaded in a variable named $file, and the field name on the Media entity is field_media_image:

$media_entities = \Drupal::entityTypeManager()->getStorage('media')->loadByProperties([
  'field_media_image' => $file->id(),
]);

$media_entity = is_array($media_entities) ? array_pop($media_entities) : NULL;

Note1 : If the File object belongs to more than a single Media entity, you will need to loop through $media_entities to find the one you want.

Note 2: $media_entity will either contain the Media entity the File entity belongs to, or be NULL if the File entity doesn't belong to a Media entity.

Actually i found a good answer, i used :

$result = \Drupal::service('file.usage')->listUsage($file);

and then in the $result i am checking if any keys called media exist. If so, i can then load my Media :)

    There is an API for doing what you want, where you don't have to do the same checks you noted. Please see my answer to this question.
