Load a media entity/object from a fid?

Question

I have the file ID (fid), and the rest of the file object.

I need to get fields from the parent media entity, but I can't find anything about loading a media entity from a file object.

Drupal 8.4.0

Update

I asked this question in relation to another: Media name as link to file

As far as I could find Kevin's comment is correct.

Answer 1

Using the service file.uses you get the file media object:

Example:

$file is a loaded file object.
$file = \Drupal::entityTypeManager()->getStorage('file')->load($fid)
$result = \Drupal::service('file.usage')->listUsage($file);

$result should now contain an array like so:

$result['file']['media']['4372'] = 2;

Where 4372 is the media id. and 2 the times the file is used.

From the docs of listUsage:

@return array
   *   A nested array with usage data. The first level is keyed by module name,
   *   the second by object type and the third by the object id. The value of
   *   the third level contains the usage count.

Answer 2

I recently needed to do the same, and came up with the following. First, load the file entity from the fid:

$fid = 1000;
$file = \Drupal\file\Entity\File::load($fid);

Then, call file_get_file_references on the file entity:

$references = file_get_file_references($file);

Per the docs, you will get back a nested array of the referencing field names, entity types, entity ids, and finally the referencing entity itself.

Answer 3

use Drupal\media\Entity\Media;
use Drupal\node\Entity\Node;

function myFunction() {
  $node_load = Node::load($nids);
  $media_field = $node_load->get('media_field_machine_name')->getString();
  $media_entity_load = Media::load($media_field); 
  $uri = $media_entity_load->field_media_video_file->entity->getFileUri(); 
  $banner_media_url = file_create_url($uri);
}

Answer 4

$file is a the loaded file object.

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

Is very relevant answer and more optimized result.
