get all country names with their state and region code

Question

Here is my Magento code:

private function getAllCountry() {

    require_once("../app/Mage.php");
    umask(0);
    Mage::app("default");

    $countryName = Mage::getModel('directory/country')->load('FR')->getName(); //get country name

    echo 'Country Name ->'.$countryName.'<br/>';

    $states = Mage::getModel('directory/country')->load('FR')->getRegions();//state names

    foreach ($states as $state)
    {
        echo 'ID->'.$state->getId().'<br/>';
        echo 'Name->'.$state->getName().'<br/>';

    }
}

I want to get the list of all country names with their states and region id in an array.

Answer 1

Note that although these answers might work, they're not the proper Magento Way™ to do this. The right path to choose is to use Service Contract.

The Directory module comes with a very handy Service Contract called the "CountryInformationAcquirerInterface". You can find it at Magento\Directory\Api\CountryInformationAcquirerInterface. This has a very handy function called getCountriesInfo(), which returns an array of CountryInformation data models, which - in their turn - have a method called getAvailableRegions(). So the full example would look something like this:

/**
 * @var \Magento\Directory\Api\CountryInformationAcquirerInterface
 */
protected $countryInformationAcquirer;

/**
 * Constructor call.
 * @param \Magento\Directory\Api\CountryInformationAcquirerInterface $countryInformationAcquirer
 */
public function __construct(
    \Magento\Directory\Api\CountryInformationAcquirerInterface $countryInformationAcquirer
) {
    $this->countryInformationAcquirer = $countryInformationAcquirer;
}

/**
 * Just a simple example
 * @return array
 */
public function example()
{
    $data = [];

    $countries = $this->countryInformationAcquirer->getCountriesInfo();

    foreach ($countries as $country) {
        // Get regions for this country:
        $regions = [];

        if ($availableRegions = $country->getAvailableRegions()) {
            foreach ($availableRegions as $region) {
                $regions[] = [
                    'id'   => $region->getId(),
                    'code' => $region->getCode(),
                    'name' => $region->getName()
                ];
            }
        }

        // Add to data:
        $data[] = [
            'value'   => $country->getTwoLetterAbbreviation(),
            'label'   => __($country->getFullNameLocale()),
            'regions' => $regions
        ];
    }

    return $data;
}

With most tasks in Magento 2, the best approach is to check first if there's a Service Contract that might fit your needs. Because most of the time, there is.

Answer 2

Try this for Magento2. It will return an multi array with country's and there regions if available.

$countryHelper = $this->_objectManager->get('Magento\Directory\Model\Config\Source\Country'); 
$countryFactory = $this->_objectManager->get('Magento\Directory\Model\CountryFactory');

$countries = $countryHelper->toOptionArray(); //Load an array of countries

    foreach ( $countries as $countryKey => $country ) {

        if ( $country['value'] != '' ) { //Ignore the first (empty) value

            $stateArray = $countryFactory->create()->setId(
                $country['value']
            )->getLoadedRegionCollection()->toOptionArray(); //Get all regions for the given ISO country code

            if ( count($stateArray) > 0 ) { //Again ignore empty values
                $countries[$countryKey]['states'] = $stateArray;
            }

        }
    }

var_dump($countries);

STAND ALONE VERSION

Add the code below to a file 'test.php' in your magento root directory and navigate to it from a web browser. By no means should you attempt to use objectmanager directly inside of a controller, but outside of magento, this is the 'approved' way of getting to it.

<?php


use Magento\Framework\AppInterface;

try {
    require __DIR__ . '/app/bootstrap.php';

} catch (\Exception $e) {
    echo 'Autoload error: ' . $e->getMessage();
    exit(1);
}
try {
    $bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);
    $objectManager = $bootstrap->getObjectManager();

    $countryHelper = $objectManager->get('Magento\Directory\Model\Config\Source\Country');
    $countryFactory = $objectManager->get('Magento\Directory\Model\CountryFactory');
    $countryCollection = $objectManager->get('Magento\Directory\Model\ResourceModel\Country\Collection');

$items = $countryCollection->loadByStore(null);

foreach ($items as $item) {
    var_dump($item->getData());
}

$countries = $countryHelper->toOptionArray(); //Load an array of countries
foreach ( $countries as $countryKey => $country ) {


if ( $country['value'] != '' ) { //Ignore the first (empty) value

            $stateArray = $countryFactory->create()->setId(
                $country['value']
            )->getLoadedRegionCollection()->toOptionArray(); //Get all regions for the given ISO country code

            if ( count($stateArray) > 0 ) { //Again ignore empty values
                $countries[$countryKey]['states'] = $stateArray;
            }

        }
    }

Answer 3

Done in two files:

Template File:

<select name="countries">
    <option class="placeholder" value="" disabled selected>Country</option>
    <?php 
        $countries = $block->getAvailableCountries();
        foreach ($countries as $country) { ?>
            <option value="<?php echo $country->getCountryId(); ?>"><?php echo $country->getName(); ?></option>
        }
    ?>
</select>

Block File:

use Magento\Directory\Model\ResourceModel\Country\CollectionFactory as CountryCollectionFactory;
use Magento\Framework\View\Element\Template;

class Catalogue extends Template
{

    protected $_countryCollectionFactory;

    public function __construct(
        CountryCollectionFactory $countryCollectionFactory,
        Template\Context $context,
        array $data = []
    )
    {
        $this->_countryCollectionFactory = $countryCollectionFactory;
        parent::__construct($context, $data);
    }

    public function getAvailableCountries()
    {
        $collection = $this->_countryCollectionFactory->create();
        $collection->addFieldToSelect('*');

        return $collection;
    }

}
