Magento 2.2.3 - Add custom required validation for company

Question

I want to add validation only for billing address on the checkout page.

By default in the backend, the company name is optional.

But if when I go to the checkout page and click on the Place Order button then I want to add require field validation for company field.

In which company name is not available so I just want to trigger that required.

Does have any idea about this?

Try this,

Add di.xml in your module

<?xml version="1.0" ?>                                                  
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Checkout\Block\Checkout\LayoutProcessor" type="vendor\module\Block\Checkout\LayoutProcessor" />

Create a LayoutProcessor.php in this path vendor\module\Block\Checkout\LayoutProcessor.php

Copy the file from

Vendor/magento/module-checkout/Block/Checkout/LayoutProcessor.php

To

app/code/vendor/module/Block/Checkout/LayoutProcessor.php

and change the below params to make the company as required field

 'company' => [
                            'validation' => [
                                'required-entry' => true,
                                'min_text_length' => 0,
                            ],
                        ],

Existing Billing Address of company field validation.

Add this file in app/code/vendor/module/etc/di.xml

add the following code,

<?xml version="1.0"?>                                           
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Checkout\Model\PaymentInformationManagement" type="Vendor\Module\Model\PaymentInformationManagement" />

Add the file in app/code/Vendor\Module\Model\PaymentInformationManagement.php

add the following code to validate empty company in billing address is not allowed.

<?php                                                         
 namespace Vendor\Module\Model;                                     
 use Magento\Framework\Exception\CouldNotSaveException;           
 class PaymentInformationManagement extends \Magento\Checkout\Model\PaymentInformationManagement                      
 {
public function savePaymentInformationAndPlaceOrder(
    $cartId,
    \Magento\Quote\Api\Data\PaymentInterface $paymentMethod,
    \Magento\Quote\Api\Data\AddressInterface $billingAddress = null
) {
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $cart = $objectManager->get('\Magento\Checkout\Model\Cart');
    $billingAddress = $cart->getQuote()->getBillingAddress();

    if (!$billingAddress->getCompany()) {
        throw new CouldNotSaveException(__('Company should not be empty in billing address'));
        return false;
    } else {
        $this->savePaymentInformation($cartId, $paymentMethod, $billingAddress);
        try {
            $orderId = $this->cartManagement->placeOrder($cartId);
        } catch (\Exception $e) {
            throw new CouldNotSaveException(
                __('An error occurred on the server. Please try to place the order again.'),
                $e
        );
        }
        return $orderId;
    }
}}

Hope this helps. Peace :)

Can you just update it to Required using the same Dropdown?
