1. 8 countries.module \country_validate()

Validates a country.

Validates and normalises the core country properties. Note that this requires the cid to test updates valids correctly.

if (country_validate($country)) {
  country_save($country);
}
else {
  foreach ($country->_errors as $property => $error_message) {
    form_set_error($property, $error_message);
  }
}

Parameters

object $country: The country object that is about to be saved.

Return value

bool TRUE if there were no errors, FALSE otherwise.

If FALSE, the $country->_errors will store an array of error messages indexed by the country property that caused the error.
