protected function AdministrativeArea::getCurrentCountry in Address 8

Gets the currently active country code.

The country source determines where to look for the country code. It can either be predefined, in which case we simply return the current value of the static country code (via form values or configuration). We can look for the country via a Views argument, in which case we determine the current value of the argument. Or we can get the country from another exposed filter, in which case we look in the form values to find the current country code from the other filter.

Return value

string The 2-letter country code.

3 calls to AdministrativeArea::getCurrentCountry()

AdministrativeArea::exposedInfo in src/Plugin/views/filter/AdministrativeArea.php

Tell the renderer about our exposed form. This only needs to be overridden for particularly complex forms. And maybe not even then.

AdministrativeArea::getValueOptions in src/Plugin/views/filter/AdministrativeArea.php

Child classes should be used to override this function and set the 'value options', unless 'options callback' is defined as a valid function or static public method to generate these values.

AdministrativeArea::valueForm in src/Plugin/views/filter/AdministrativeArea.php

Options form subform for setting options.
