Support for fields of type "country" (patch included)

Problem/Motivation

Currently, the module does not support import for for fields of type "country" (module Countries)

Proposed resolution

The reason the import process is unable to import countries data is because they have no "value" key, they use an "iso2" key instead, so default processing method does not work.

Note: ISO2 refers to the ISO 3166 alpha-2 two-letter country code.

User interface changes

In order to use this patch, you need to configure your import setup accordingly, so the module "knows" that a custom field of type "country" is included.

In section "4. Which vocabulary do you want to import into?", field "Set custom fields of the vocabulary", add your country field like this:

field_country_of_origin|country
