Page History

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

Description

This Field Type 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").

PHP API Field Type 

Value Object

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

Info
Note that both BinaryFile and Media Value and Type inherit from the BinaryBase abstract Field Type, and share common 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/63cd472dd7819da7b75e8e2fee507c68.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_ezpublish5 light.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*  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

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.

Example: 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:

<field>
    <fieldDefinitionIdentifier>file</fieldDefinitionIdentifier>
    <languageCode>eng-GB</languageCode>
    <fieldValue>
        <value key="fileName">My file.pdf</value>
        <value key="fileSize">17589</value>
        <value key="data"><![CDATA[/9j/4AAQSkZJRgABAQEAZABkAAD/2wBDAAIBAQIBAQICAgICAgICAwUDAwMDAwYEBAMFBwYHBwcG
...
...]]></value>
    </fieldValue>
