What鈥檚 in this topic
The default Magento Checkout consists of two steps:
- Shipping Information
- Review and Paymetns Information
You can add a custom checkout step, it should be implemented as a UI component. For the sake of compatibility, upgradability and easy maintenance, do not edit the default Magento code, add your customizations in a separate module.
This topic describes how to create the frontend part of the component, implementing a checkout step, and how to add it to the checkout flow.
Create the view part of the checkout step component
To create the view part of the new checkout step:
- Add a module directory (not covered in this topic). See Build your module for details). All custom files must be stored there. For your checkout customization to be applied correctly, your custom module should depend on the Magento_Checkout module.
- Create the
.jsfile implementing the view model. - Create an
.htmltemplate for the component.
Each step is described in details in the folowing paragraphs.
Add the JavaScript file implementing the new step
A new checkout step must be implemented as UI component. That is, its JavaScript implementation must be a JavaScript module.
The file must be stored under the <your_module_dir>/view directory.
A sample view/my-step-view.js with comments follows:
define(
[
'ko',
'uiComponent',
'underscore',
'Magento_Checkout/js/model/step-navigator'
],
function (
ko,
Component,
_,
stepNavigator
) {
'use strict';
/**
*
* mystep - is the name of the component's .html template,
* your_module_dir - is the name of the your module directory.
*
*/
return Component.extend({
defaults: {
template: 'your_module_dir/mystep'
},
//add here your logic to display step,
isVisible: ko.observable(true),
/**
*
* @returns {*}
*/
initialize: function () {
this._super();
// register your step
stepNavigator.registerStep(
//step code will be used as step content id in the component template
'step_code',
//step alias
null,
//step title value
'Step Title',
//observable property with logic when display step or hide step
this.isVisible,
_.bind(this.navigate, this),
/**
* sort order value
* 'sort order value' < 10: step displays before shipping step;
* 10 < 'sort order value' < 20 : step displays between shipping and payment step
* 'sort order value' > 20 : step displays after payment step
*/
15
);
return this;
},
/**
* The navigate() method is responsible for navigation between checkout step
* during checkout. You can add custom logic, for example some conditions
* for switching to your custom step
*/
navigate: function () {
},
/**
* @returns void
*/
navigateToNextStep: function () {
stepNavigator.next();
}
});
}
);Add the .html template
In the module directory, add the .html template for the component. It must be located under the <your_module_dir>/view/frontend/web/template directory.
A sample mystep.html follows:
<!--The 'step_code' value from the .js file should be used-->
<li id="step_code" data-bind="fadeVisible: isVisible">
<div class="step-title" data-bind="i18n: 'Step Title'" 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">
<div class="primary">
<button data-role="opc-continue" type="submit" class="button action continue primary">
<span><!-- ko i18n: 'Next'--><!-- /ko --></span>
</button>
</div>
</div>
</form>
</div>
</li>Add your step to the Checkout page layout
For the new step to be displayed on the page, you need to declare it in the Checkout page layout, which is defined in checkout_index_index.xml.
So you need to add an extending checkout_index_index.xml layout file in the following location: <your_module_dir>/view/frontend/layout/checkout_index_index.xml
A sample checkout_index_index.xml follows:
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>

<!-- The new step you add -->
<item name="my-new-step" xsi:type="array">
<item name="component" xsi:type="string">Magento_Your_Module_Name/js/view/my-step-view</item>
<!--To display step content before shipping step "sortOrder" value should be < 1-->
<!--To display step content between shipping step and payment step 1 < "sortOrder" < 2 -->
<!--To display step content after payment step "sortOrder" > 2 -->
<item name="sortOrder" xsi:type="string">2</item>
<item name="children" xsi:type="array">
<!--add here child component declaration for your step-->
</item>

</referenceBlock>
