FileUsageBase::add

public FileUsageBase::add(FileInterface $file, $module, $type, $id, $count = 1)

Records that a module is using a file.

Examples:

  • A module that associates files with nodes, so $type would be 'node' and $id would be the node's nid. Files for all revisions are stored within a single nid.
  • The User module associates an image with a user, so $type would be 'user' and the $id would be the user's uid.

Parameters

\Drupal\file\FileInterface $file: A file entity.

string $module: The name of the module using the file.

string $type: The type of the object that contains the referenced file.

int $id: The unique, numeric ID of the object containing the referenced file.

int $count: (optional) The number of references to add to the object. Defaults to 1.
