I am making a magento 2 module, and I had to create a custom shipping method but I am not able to get the data of fields in the checkout page :

This is a part of my system.xml file

 <section id="carriers" translate="label" type="text" sortOrder="320" showInDefault="1" showInWebsite="1" showInStore="1">

 <group id="my_shipping_methode" translate="label" type="text" sortOrder="0" showInDefault="1" showInWebsite="1" showInStore="1">

 <field id="myfield" translate="label" type="text" sortOrder="80" showInDefault="1" showInWebsite="1" showInStore="1" canRestore="1">

and this is the constructor of my module :

<?php namespace ABModelCarrier; 
use MagentoQuoteModelQuoteAddressRateRequest;
use MagentoShippingModelRateResult;

class Shipping extends MagentoShippingModelCarrierAbstractCarrier implements
 MagentoShippingModelCarrierCarrierInterface
{
 /**
 * @var string
 */
 protected $_code = 'my_shipping_methode';

 /**
 * @var string
 */
 protected $myfield = 'test';

And this is part of my javascript file I call in the checkout to get the code of the shipping method :

this.selectedMethod = ko.computed(function() {
 var method = quote.shippingMethod();
 var selectedMethod = method != null ? method.method_code : null;

I tried to do the same for my field but it didn't work

var myfield = method != null ? method.method_myfield : null;

Please help I am lost

Your protected code should be equal to the name of your system.xml group configuration. Instead of protected $_code = 'thecode';, It should be:

protected $_code = 'my_shipping_methode'; 

Solved !!

This is how I did it :

<?php

namespace MageplazaSimpleshippingModel;

use MagentoCheckoutModelConfigProviderInterface;

/**
 * Class SampleConfigProvider
 */
class SampleConfigProvider extends MagentoFrameworkAppHelperAbstractHelper implements ConfigProviderInterface


 /**
 * Retrieve assoc array of checkout configuration
 *
 * @return array
 */
 public function getConfig()
 
 $postTest = $this->scopeConfig->getValue(
 'carriers/simpleshipping/myfield',
 MagentoStoreModelScopeInterface::SCOPE_STORE);


 return [
 'foo' => [
 'bar' => $postTest,
 ],
 ];
 

In my javascript :

getSampleTotal: function () ;
 return window.checkoutConfig.foo.bar;
 

In my template :

<div class="component-wrapper">
 <p data-bind="html: getSampleTotal()"></p>
 </div>

in 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">

 <argument name="configProviders" xsi:type="array">
 <item name="Mageplaza_Simpleshipping_config_provider" xsi:type="object">MageplazaSimpleshippingModelSampleConfigProvider</item>
 </argument>
 </arguments>
 </type>
</config>

system.xml

 <section id="carriers" translate="label" type="text" sortOrder="320" showInDefault="1" showInWebsite="1" showInStore="1">

 <group id="simpleshipping" translate="label" type="text" sortOrder="0" showInDefault="1" showInWebsite="1" showInStore="1">

 <field id="myfield" translate="label" type="text" sortOrder="80" showInDefault="1" showInWebsite="1" showInStore="1" canRestore="1">
