BinaryFile Field Type

ThisĀ Field Type represents and handles a single binary file. It also counts the number of times the file has been downloaded from the content/download module.

It is capable of handling virtually any file type and is typically used for storing legacy document types such as PDF files, Word documents, spreadsheets, etc. The maximum allowed file size is determined by the "Max file size" class attribute edit parameter and the upload_max_filesize directive in the main PHP configuration file (php.ini).

Value Object

Properties

Note that both BinaryFile and Media Value and Type inherit from the BinaryBase abstract Field Type, and share common properties.

eZ\Publish\Core\FieldType\BinaryFile\Value offers the following properties:

Attribute Type Description Example
id string Binary file identifier. This ID depends on the IO Handler that is being used. With the native, default handlers (FileSystem and Legacy), the ID is the file path, relative to the binary file storage root dir (var/<vardir>/storage/original by default). application/63cd472dd7.pdf
fileName string The human-readable file name, as exposed to the outside. Used when sending the file for download in order to name the file. 20130116_whitepaper.pdf
fileSize int File size, in bytes. 1077923
mimeType string The file's MIME type. application/pdf
uri string The binary file's content/download URI. If the URI doesn't include a host or protocol, it applies to the request domain. /content/download/210/2707
downloadCount integer Number of times the file was downloaded 0
path string deprecated N/A

Hash format

The hash format mostly matches the value object. It has the following keys:

  • id
  • path (for backwards compatibility)
  • fileName
  • fileSize
  • mimeType
  • uri
  • downloadCount

Example:

1
2
3
4
5
6
7
8
[
    'id' => 'some/file/here',
    'fileName' => 'sindelfingen.jpg',
    'fileSize' => 2342,
    'downloadCount' => 0,
    'mimeType' => 'image/jpeg',
    'uri' => 'http://some/file/here',
]

REST API specifics

Used in the REST API, a BinaryFile Field will mostly serialize the hash described above. However there are a couple specifics worth mentioning.

Reading content: url property

When reading the contents of a Field of this type, an extra key is added: url. This key gives you the absolute file URL, protocol and host included.

Example:Ā http://example.com/var/ezdemo_site/storage/original/application/63cd472dd7819da7b75e8e2fee507c68.pdf

Creating content: data property

When creating BinaryFile content with the REST API, it is possible to provide data as a base64 encoded string, using the data fieldValue key:
