Magento2: How to get guest email address in checkout?

Question

Please, how to get guest email address in checkout?

Answer 1

In your custom-method.js file

define(
[
    'jquery',
    'Magento_Checkout/js/model/quote'
],
function ($,quote,Component,) {
    'use strict';

    return Component.extend({

        defaults: {
            template: 'Namespace_ModuleName/custompayment/form_template'
        },

        getGuestEmail: function () {
            return quote.guestEmail;
        }

    });
}
);

After that just call that function you will get guest email address If you want register customer email address then use following:

        getEmail: function () {
            return window.checkoutConfig.customerData.email;
        }

Answer 2

You can get it using javascript in checkout page using below method,

if(!window.checkoutConfig.quoteData.customer_id){
  var getGuestEmail = window.checkoutConfig.quoteData.customer_email;
  alert(getGuestEmail);
}

Using above code you can get guest email id. I haven't check with php methods.

Answer 3

• In case of the Guest customer, magento didn't map email id to shipping or billing address before place order.
• In my case, I need guest email which is provided at the time of shipping page. To validate Guest email with Coupon code using this event ( salesrule_validator_process ) .

To Do that : Step 1: Create di.xml to override core 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\Customer\Model\AccountManagement" type="Custom\Couponfriend\Model\AccountManagement" />
</config>

Step 2: Override model in custom module, and set email to
Quote's->shipping object. and get where you need it.

<?php

namespace Custom\Couponfriend\Model;

class AccountManagement extends \Magento\Customer\Model\AccountManagement {

    public function isEmailAvailable($customerEmail, $websiteId = null) {
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $cart = $objectManager->get('\Magento\Checkout\Model\Cart');
        $shippingAddress = $cart->getQuote()->getShippingAddress();

        $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/guestFriendsFamily.log');
        $logger = new \Zend\Log\Logger();
        $logger->addWriter($writer);
        $logger->info('------------');

        try {
            if ($shippingAddress) {
                $shippingAddress->setData('email', $customerEmail);
                $shippingAddress->save();
            }
        } catch (NoSuchEntityException $e) {
            $logger->info($e->getMessage());
        }

        try {
            if ($websiteId === null) {
                $websiteId = $this->storeManager->getStore()->getWebsiteId();
            }
            $this->customerRepository->get($customerEmail, $websiteId);
            return false;
        } catch (NoSuchEntityException $e) {
            return true;
        }
    }

}

?>

You can override constructor to create cart object using dependency injection

This work for Magento 1

<?php 
       class Exinent_Billingtax_Model_Observer 
       {
            public function autoRegisterBilling($evt){
                if(!Mage::helper('customer')->isLoggedIn()){
                    $data =$evt->getEvent()->getControllerAction()->getRequest()->getPost('billing', array());
                echo "<pre>";
                print_r($data);
                $customer = Mage::getModel("customer/customer");
                $email = $data['email'];
                $websiteId = Mage::app()->getWebsite()->getId();
                $store = Mage::app()->getStore();
                $pwd = $data['customer_password'];
                $customer->setWebsiteId(Mage::app()->getStore()->getWebsiteId())->loadByEmail($email);

                if (!$customer->getId()) {
                     //Code begins here for new customer registration
                    $customer->website_id = $websiteId;
                    $customer->setStore($store);
                    $customer->firstname = $data['firstname'];
                    $customer->lastname = $data['lastname'];
                    $customer->setEmail($email);
                    $customer->setPassword($pwd);
                    $customer->sendNewAccountEmail('confirmed');  
                    $customer->save();
                       }
                Mage::getSingleton('customer/session')->loginById($customer->getId()); // to login that customer.
               }
        }

    }

You can get guest and customer other information in you custom js like customerinfo.js in Magento_Checkout/js/model/quote

define(
    [
        'jquery',
        'Magento_Checkout/js/view/payment/default',
        'Magento_Checkout/js/model/quote',
        'Magento_Checkout/js/action/place-order',
    ],
    function ($,Component,quote,placeOrderAction) {
        'use strict';

        return Component.extend({

            defaults: {
                template: 'Company_Module/custompayment/form_template'
            },

            getEmail: function () {
                if(quote.guestEmail) return quote.guestEmail;
                else return window.checkoutConfig.customerData.email;
            },

            getLastName: function () {
                return quote.billingAddress().lastname;
            },

            getFirstName: function () {
                return quote.billingAddress().firstname;
            },

            getAddress: function () {
                return quote.billingAddress().street[0]+", "+quote.billingAddress().postcode+" "+quote.billingAddress().city+", Maroc";
            },

            getPhone: function () {
                return quote.billingAddress().telephone;
            },

        });
    }
);
