How to get the url of a file field of a given node?

Question

$node->field_file gives me a FileFieldItemList while the first entry seems to be a FileItem.

$node->field_file->getValue() gives me an integer (I guess the file id). How can I actually get the downloadable file uri from that?

Answer 1

// Load the file.
$file = \Drupal\file\Entity\File::load($fid);
// Get the URL.
$url = \Drupal::service('file_url_generator')
  ->generateAbsoluteString($file->getFileUri());

Before Drupal 10, there was a different way of doing it using file_create_url().

$url = file_create_url($file->getFileUri());

Answer 2

As of 9.3.0 file_create_url is deprecated and it will be removed from 10.0.0 version. The new way to do it:

$file_uri = $node->field_file->entity->getFileUri();
\Drupal::service('file_url_generator')->generateString($file_uri);

This service has the following functions:
generate() generateString() generateAbsoluteString() transformRelative()

Answer 3

It is also possible to do one-liner with magic method:

$node->field_file->entity->getFileUri();

Or to render as string

Option 1: $node->field_file->entity->url();

Option 2: file_create_url($node->field_file->entity->getFileUri());

Answer 4

For Drupal 9.3.0+ users, as mentionned :

• File:url() is deprecated as of 8.7.x.
• file_create_url() is deprecated in drupal:9.3.0 and is removed from drupal:10.0.0

$file->createFileUrl() looks to be the new simplest solution.

It uses the 'file_url_generator' service mentionned by golddragon007.

You'll find details in the File.php core's file.
