function _file_types_build

Builds and returns the list of available file types.

This function reads from disk individual config files that define the available content types in the system. Modules may bundle a file type with their module by including a "file.type.[type_name].json" config file in their module's config directory. Each file should contain:

• type: (required)
• name: (required) The human-readable name of the file type.
• description: (required) A brief description of the file type.
• mimetypes: (required)

Return value

An object with two properties::

• names: Associative array of the names of file types, keyed by the type.
• types: Associative array of file type objects, keyed by the type.

These arrays will also include obsolete types: types that were previously defined by modules that have been disabled, likely by a module that was provided a file type and then was disabled. These are indicated in the type object by $type->disabled being set to TRUE.

File

core/modules/file/file.module, line 2413

Defines a "managed_file" Form API field and a "file" field for Field module.
