Magneto 2: Different countries in billing and shipping address

Question

How to limit the countries in the shipping address, for example, I want to allow all countries in billing address but only one in the shipping address( at the moment). Any idea how to achieve this in Magento 2.3.1 community ..

Answer 1

For show only one country in shipping address country dropdown we have to create plugin of LayoutProcessor method for override country_id children field of shipping-address-fieldset which we found in module-checkout/view/frontend/layout/checkout_index_index.xml file.

registration.php

<?php

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Trecks_Checkoutcountry',
    __DIR__
);

etc/module.xml:-

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Trecks_Checkoutcountry" setup_version="1.0.0">
        <sequence>
            <module name="Magento_Checkout"/>
        </sequence>
    </module>
</config>

etc/frontend/di.xml:-

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <type name="\Magento\Checkout\Block\Checkout\LayoutProcessor">
        <plugin name="Treckslayoutprocessor" type="Trecks\Checkoutcountry\Plugin\LayoutProcessor"/>
    </type>
</config>

Plugin/LayoutProcessor.php:-

Here you can put different countries code in $countryIds of getCountryOptions() for show particular countries in dropdown.

<?php

namespace Trecks\Checkoutcountry\Plugin;
use Magento\Directory\Helper\Data as DirectoryHelper;

class LayoutProcessor
{

    protected $countryOptions;

    public function __construct(
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Directory\Model\ResourceModel\Country\CollectionFactory $countryCollection,
        DirectoryHelper $directoryHelper
    ) {
        $this->_storeManager = $storeManager;
        $this->countryCollectionFactory = $countryCollection;
        $this->directoryHelper = $directoryHelper;
    }

   
    public function afterProcess(
        \Magento\Checkout\Block\Checkout\LayoutProcessor $subject,
        $result
    ) {

        $result['components']['checkout']['children']['steps']['children']['shipping-step']['children']
        ['shippingAddress']['children']['shipping-address-fieldset']['children']['country_id'] = [
            'component' => 'Magento_Ui/js/form/element/select',
            'config' => [
                'customScope' => 'shippingAddress',
                'template' => 'ui/form/field',
                'elementTmpl' => 'ui/form/element/select',
                'id' => 'drop-down',
            ],
            'dataScope' => 'shippingAddress.country_id',
            'label' => 'Country',
            'provider' => 'checkoutProvider',
            'visible' => true,
            'validation' => [],
            'sortOrder' => 70,
            'id' => 'drop-down',
            'options' => $this->getCountryOptions()
        ];
        return $result;
    }

    public function getStoreId()
    {
        return $this->_storeManager->getStore()->getId();
    }

    //We have refernce this function from Magento\Checkout\Block\Checkout\DirectoryDataProcessor
    public function getCountryOptions()
    {
            $countryIds = array("US");
            //$countryIds = array("US","CA");
           
            $countryselection = $this->countryCollectionFactory->create()->loadByStore(
                $this->_storeManager->getStore()->getId());
            $countryselection->addFieldToFilter('country_id', ['in' => $countryIds]);
            $countryselection = $countryselection->toOptionArray();
            $countryarray = $this->orderCountryOptions($countryselection);

        return $countryarray;
    }


    public function orderCountryOptions(array $countryOptions)
    {
        $topCountryCodes = $this->directoryHelper->getTopCountryCodes();
        if (empty($topCountryCodes)) {
            return $countryOptions;
        }

        $headOptions = [];
        $tailOptions = [[
            'value' => 'delimiter',
            'label' => '──────────',
            'disabled' => true,
        ]];
        foreach ($countryOptions as $countryOption) {
            if (empty($countryOption['value']) || in_array($countryOption['value'], $topCountryCodes)) {
                $headOptions[] = $countryOption;
            } else {
                $tailOptions[] = $countryOption;
            }
        }
        return array_merge($headOptions, $tailOptions);
    }
}

Hope it works. Thanks.

Answer 2

I don't believe this is currently possible to achieve through configuration in Magento 2.3, see this github issue for reference. It is possible to allow all countries for shipping and restrict the payment methods based on country, but not vice versa. A Magento extension would have to be implemented (or purchased) to achieve this behaviour. I am unsure of any 3rd party extensions that provide this.
