Magento register for account at checkout

Question

Does anyone know whether it is possible to move the customer registration step to the checkout like in the original Magento 1 checkout? Looking for an extension that will do this for me or advice on how I could achieve this.

Answer 1

I Would go about by creating a step in checkout this detects whether you are logged in or not and then shows the form accordingly.

Load the registration form into this step over ajax and modify the after register event detecting whether registration was made the checkout redirecting back to checkout rather than the dashboard.

I got as far as adding a working step that shows when not signed in for registration and redirecting the registration success back to checkout disabling the previous step for a smooth user experience.

Offering a login option if the user has an account but has not logged in at this stage would improve further here.

This is full code if you want to check over all of it was a lot to include in the answer:

Create a register form within controller:

As the checkout steps need some php to run to get the form url and key etc a controller will be needed so we can load this register form over ajax into the step.

<?php
namespace Harrigo\RegisterCheckout\Controller\Index;

use Magento\Framework\Controller\ResultFactory;

class Register extends \Magento\Framework\App\Action\Action
{
    protected $resultPageFactory;
    
    /**
     * Constructor
     * 
     * @param \Magento\Framework\App\Action\Context  $context
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    )
    {
        $this->resultPageFactory = $resultPageFactory;
        $this->_resultFactory = $context->getResultFactory();
        parent::__construct($context);
    }
    
    /**
     * Execute view action
     * 
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        //if (isset($_POST["cart"])) {
            $resultLayout = $this->resultFactory->create(ResultFactory::TYPE_LAYOUT);
            return $resultLayout;   
        //}
        //$this->_redirect('checkout/');

    }
}

Controller/Index/Register.php

The below renders the registration blocks within controller so we can then call over ajax into the checkout.

<?xml version="1.0"?>
<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">

                    </argument>
                </arguments>
            </block>
            <block class="Magento\Framework\View\Element\Template" name="form_additional_info_customer" template="Magento_Customer::additionalinfocustomer.phtml"/>
  </container>
</layout>

/view/frontend/layout/harrigoregister_index_register.xml

Make sure to add routes.xml within the etc/frontend folder of the module.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="harrigoregister" frontName="harrigoregister">
            <module name="Harrigo_RegisterCheckout" />
        </route>
    </router>
</config>

Create a checkout step:

http://devdocs.magento.com/guides/v2.0/howdoi/checkout/checkout_new_step.html

As this is first step make sure to add the mixins just like I have done in module as the devdocs is incorrect here leading to every step showing:

<!--The 'step_code' value from the .js file should be used-->
<li id="registerstep" data-bind="fadeVisible: isVisible">
<div class="step-title" data-bind="i18n: 'Register'" data-role="title"></div>
    <div id="checkout-step-title"
         class="step-content"
         data-role="content">
        <form data-bind="submit: navigateToNextStep" novalidate="novalidate">
            <div class="actions-toolbar" id="shipping-method-buttons-container">
                <div class="primary">
                    <button data-role="opc-continue" type="submit" class="button action continue primary">
                        <span><!-- ko i18n: 'Continue as guest'--><!-- /ko --></span>
                    </button>
                </div>
            </div>
        </form>
    </div>  
    <div id="registerblock"></div>
</li>

This was failing if block hadn't loaded before the ajax call but ended up using something like this to get our registration form from the controller and spit it onto the step:

//waits for elements to load in checkout
function waitForElement(elementPath, callBack){
  window.setTimeout(function(){
    if($(elementPath).length){
      callBack(elementPath, $(elementPath));
    }else{
      waitForElement(elementPath, callBack);
    }
  },500)
}

//get crosssell products / newsletter
$.ajax({
  url: "/harrigoregister/index/register",
  type: "post",
  data: { 
    cart: "yes"
  },
  success: function(response) {
    waitForElement("#registerblock",function(){
                $("#registerblock").html(response);
        });
  },
  error: function(xhr) {
  }
});

There are a lot more steps here just follow the devdocs making sure to do the mixin step but use below for mixin as devdocs example doesn't work:

define(
    [
        'ko',
        'Magento_Customer/js/model/customer'
    ], function (ko, customer) {
        'use strict';

        var mixin = {

            initialize: function () {
                if(!customer.isLoggedIn()) {
                    this.isVisible = ko.observable(false);
                    this.visible = ko.observable(false); // set visible to be initially false to have your step show first
                }
                    this._super();
                
                return this;
            }
        };

        return function (target) {
            return target.extend(mixin);
        };
    }
);

Main differences were the payment and shipping steps use isVisible and Visible and devdocs only uses visible within example so isVisible needed to be added to fix. Also had to make adjustments for if the step was disabled.

Modify Registration Redirect:

https://magento.stackexchange.com/questions/131850/magento-2-redirect-user-to-specific-page-after-register

<?php

namespace Harrigo\RegisterCheckout\Plugin;

use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\Registry;
use Magento\Framework\UrlInterface;

class Redirect
{
    protected $coreRegistry;

    protected $url;

    protected $resultFactory;


    public function __construct(Registry $registry, UrlInterface $url, ResultFactory $resultFactory)
    {
        $this->coreRegistry = $registry;
        $this->url = $url;
        $this->resultFactory = $resultFactory;
    }

    public function aroundGetRedirect ($subject, \Closure $proceed)
    {
        //need to check out if registration was from checkouit
        /** @var \Magento\Framework\Controller\Result\Redirect $result */

        if ($_POST['checkout'] = 'true') {
            $result = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
            $result->setUrl($this->url->getUrl('checkout'));
            return $result;
        }

        return $proceed();
    }
}

Rough example but also had to override the register.phtml to add the checkout post variable to determine the difference between the 2 forms. There where a lot of steps I didnt show but check the module i created for complete example.
