File interface
- 8.x drupal/core/includes/file.inc file
- 6.x drupal/includes/file.inc file
- 7.x drupal/includes/file.inc file
Common file handling functions.
Fields on the file object:
- fid: File ID
- uid: The {users}.uid of the user who is associated with the file.
- filename: Name of the file with no path components. This may differ from the basename of the filepath if the file is renamed to avoid overwriting an existing file.
- uri: URI of the file.
- filemime: The file's MIME type.
- filesize: The size of the file in bytes.
- status: A bitmapped field indicating the status of the file. The first 8 bits are reserved for Drupal core. The least significant bit indicates temporary (0) or permanent (1). Temporary files older than DRUPAL_MAXIMUM_TEMP_FILE_AGE will be removed during cron runs.
- timestamp: UNIX timestamp for the date the file was added to the database.
