1 file.module file_file_formatter_file_field_settings($form, &$form_state, $settings, $formatter_type, $file_type, $view_mode)

Implements hook_file_formatter_FORMATTER_settings().

This function provides a bridge to the field formatter API, so that file field formatters can be reused for displaying the file entity's file pseudo-field.

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

    $field_formatter_type = substr($formatter_type, strlen('file_field_'));
    $field_formatter_info = field_info_formatter_types($field_formatter_type);

    // Invoke hook_field_formatter_settings_form(). We are reusing field
    // formatter functions, but we are not working with a Field API field, so
    // set $field accordingly. Unfortunately, the API is for $settings to be
    // transferred via the $instance parameter, so we must mock it.
