This extension requires no configuration, simply install it using the extension manager. However, if you wish to use the new field type “file_references” for your own extension, just configure it like other “group” fields (e.g. as created by the kickstarter) and set the internal_type to “file_references”.

Example configuration:

    "tx_emreferences_filereferences" => Array (

        "exclude" => 1,

        "label" => "LLL:EXT:em_references/locallang_db.xml:tt_content.tx_emreferences_filereferences",

        "config" => Array (

            "type" => "group",

            "internal_type" => "file_references",

            "allowed" => $GLOBALS["TYPO3_CONF_VARS"]["GFX"]["imagefile_ext"],

            "max_size" => 1000,

            "show_thumbs" => 1,

            "size" => 3,

            "minitems" => 0,

            "maxitems" => 10,

        )

    ),

All options that are valid for the other interal_types of the “group” field documented in the TYPO3 Core API are valid for the new interal_type “file_references” as well.
