This FieldType allows the storage and retrieval of a single file. 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").

BinaryFile Value Object API

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

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

idstringBinary 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). This attribute has been introduced in eZ Publish 5.2.application/63cd472dd7819da7b75e8e2fee507c68.pdf
fileNamestringThe human readable file name, as exposed to the outside. Used when sending the file for download in order to name the file.20130116_whitepaper_ezpublish5 light.pdf
fileSizeintFile size, in bytes1077923
mimeTypestringThe file's mime type.application/pdf

The binary file's HTTP uri. If the URI doesn't include a host or protocol, it applies to the request domain. This attribute has been introduced in eZ Publish 5.2.

The URI is not publicly readable, and must NOT be used to link to the file for download. Use ez_render_field to generate a valid link to the download controller.


Since v5.4 the property contains the binary file's content/download URL.

 Renamed to id starting from eZ Publish 5.2. Can still be used, but it is recommended not to use it anymore as it will be removed.


BinaryFile 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

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.


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:
