Magento 2 Knockout XML->PHTML->JS->HTML

Question

I want to display static block in html login popup during checkout, but there is a problem.

This is the html template which is called from js, this js is called from phtml, and this phtml template called from xml layout. ( xml -> phtml -> js -> html)

So the question is how to send custom content block from the phtml or xml throught js to html template

vendor/magento/module-catalog/view/frontend/layout/default.xml

This file is calling pthml template with

 <block class="Magento\Customer\Block\Account\AuthenticationPopup" name="authentication-popup" as="authentication-popup" template="Magento_Customer::account/authentication-popup.phtml">

vendor/magento/module-customer/view/frontend/templates/account/authentication-popup.phtml

This file is calling js layout with code:

 <script type="text/x-magento-init">
 {
 "#authenticationPopup": {
 "Magento_Ui/js/core/app": <?= /* @noEscape */ $block->getJsLayout() ?>
 }
 }
 </script>

vendor/magento/module-customer/view/frontend/web/js/view/authentication-popup.js

this file is called the last html template where should be a static block from admin panel, with code:

 define([
 'jquery',
 'ko',
 // ......... //
], function (,ドル ko, /* ... ... ... .... ... */) {
 'use strict';
 return Component.extend({
 registerUrl: window.authenticationPopup.customerRegisterUrl,
 forgotPasswordUrl: window.authenticationPopup.customerForgotPasswordUrl,
 autocomplete: window.authenticationPopup.autocomplete,
 modalWindow: null,
 isLoading: ko.observable(false),
 defaults: {
 template: 'Magento_Customer/authentication-popup'
 },
 });
});

this is how i get this block in php

<?php echo $this->getLayout()->createBlock('Magento\Cms\Block\Block')->setBlockId('reset_password_notice')->toHtml(); ?>

I tried to paste it to phtml, it doesn't work !!!

Answer 1

The problem is solved by myself. So for the first step, I started looking for a data provider which helps to send data from pthml throught js to html in vendor/module-customer/

There I found the file vendor/module-customer/Model/Checkout/ConfigProvider.php. That was exactly what I need.

Following this link I create:

1. app/code/Theme/Customer/etc/frontend/di.xml with code:

    <type name="Magento\Checkout\Model\CompositeConfigProvider">
    <arguments>
    <argument name="configProviders" xsi:type="array">
    <item name="cms_block_config_provider" xsi:type="object">Theme_Name\Customer\Model\Checkout\ConfigProvider</item>
    </argument>
    </arguments>
    </type>
   

2. The next step was to create a class which is called in item tag: Theme_Name/Customer/Model/Checkout/ConfigProvider.php with code that extends
   vendor/module-customer/Model/Checkout/ConfigProvider.php

Note! They both implement the same ConfigProviderInterface. So in new ConifgProvider.php we use the same interface to extend data-provider correctly

<?php
namespace Theme_Name\Customer\Model\Checkout;
use Magento\Checkout\Model\ConfigProviderInterface;
use Magento\Framework\View\LayoutInterface;
class ConfigProvider implements ConfigProviderInterface
{
 /** @var LayoutInterface */
 protected $_layout;
 public function __construct(LayoutInterface $layout)
 {
 $this->_layout = $layout;
 }
 public function getConfig()
 {
 $cmsBlockId = 'block_ID'; // id of cms block to use
 return [
 'cms_block_message' => $this->_layout->createBlock('Magento\Cms\Block\Block')->setBlockId($cmsBlockId)->toHtml()
 ];
 }
}

Good. The provider is configured.

3)The last one needed to override the frontend html KO template:

app/design/frontend/theme_name/Magento_Customer/web/template/authentication-popup.html

Write the next:

<div data-bind="html: window.checkoutConfig.cms_block_message"></div>
