File Compressor field

This module provides a "File Compressor" field type that allows to archive and compress attached files to an entity into a single file.

Given that this file is inside a new field on the entity, this module provides full integration with the entity system out of the box. Entity revisions and multilingual features work out of the box.

This field is totally hidden during the entity creation process, and makes use of default File field formatters to display the compressed file.

Installation

Follow the normal Drupal module installation procedures.

Usage

Usage is straightforward. Add a "File Compressor" field to any entity and select the fields you want to include in the automatically generated compressed file from the list.

Configure the field visibility in the "Manage Display" tab.

Create a new entity, upload attachments for the fields selected above and save.

If you made visible the File Compressor field, you will be able to download all the attachments to the entity in a single compressed file.

Note: By default, File Compressor field module only gives support for File and Image fields. Besides of that, provides hooks to extend it to other file based fields.

Requirements

This module provides by default two PHP Compressor plugins, Zip and GZip and two SYSTEM variants of compressing: zip, tar. This list can be extended using hooks. Each zip provider requires a different PHP library or installed system's zip, tar extensions:

• Zip: php_zip extension. PHP Zip Documentation
• GZip: Archive Tar PEAR package. Archive Tar Documentation
• System Zip: Utilizes the system's "zip" command.
• System Tar: Utilizes the system's "tar" command.
