I'm customizing the checkout process in magento 2 by adding a custom step between Shipping and Payment steps and by adding a checkbox in Shipping step.

The problem

When going to checkout page for the first time both my Shipping and Custom steps are selected as shown in the image.

checkout problem

So there are two questions:

  1. How can i make that only the Shipping step is visible when i go to checkout page for the first time?

  2. How can i make that if i select the checkbox that i added in Shipping step, i skip my Custom step (going directly from shipping to payment) but if i do not select the checkbox i go to my Custom step?

What i have done so far

I've created the custom step using the documents provided by magento team in http://devdocs.magento.com/guides/v2.1/howdoi/checkout/checkout_new_step.html

This is my Vendor_CustomCheckout/view/frontend/web/js/view/step-view.js

define(
[
    'ko',
    'uiComponent',
    'underscore',
    'Magento_Checkout/js/model/step-navigator',
    'Magento_Ui/js/form/form'
],
function (
    ko,
    Component,
    _,
    stepNavigator
) {
    'use strict';
    /**
     *
     * mystep - is the name of the component's .html template,
     * <Vendor>_<Module>  - is the name of the your module directory.
     *
     */
    return Component.extend({
        defaults: {
            template: 'Vendor_CustomCheckout/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
                'custom_step',
                //step alias
                null,
                //step title value
                'Direccion de Facturacion',
                //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 () {
            this.isVisible(false);
            this.isVisible = false;
        },

        /**
         * @returns void
         */
        navigateToNextStep: function () {
            // trigger form validation
            this.source.set('params.invalid', false);
            this.source.trigger('customStepForm.data.validate');
            console.dir(this.isVisible);
            // verify that form data is valid
            if (!this.source.get('params.invalid')) {
                // data is retrieved from data provider by value of the customScope property
                var formData = this.source.get('customStepForm');
                // do something with form data
                console.dir(formData);
            }
            stepNavigator.next();
        }
    });
}
);

  1. Instead of you, I added the new custom step before and not after the Shipping Information step but I discovered the same behavior. Did you managed to solve it?
  2. It should be possible to use the navigateTo(code, scrollToElement) function of the Magento_Checkout/js/model/step-navigator for this purpose.
    • Actual the next() function of the step-navigator.js is called in the setShippingInformation() function of the Magento_Checkout/js/view/shipping.js(which will be called by clicking the Next button).
    • In order to override this function you can copy the whole shipping.js file to your custom module and add the following to your custom checkout_index_index.xml.

checkout_index_index.xml

<item name="steps" xsi:type="array">
...
    <item name="shipping-step" xsi:type="array">
        <item name="children" xsi:type="array">
            <item name="shippingAddress" xsi:type="array">
                <item name="component" xsi:type="string"><Vendor>_<ModuleName>/js/view/shipping</item>
            </item>
        </item>
    </item>
...
</item>

If this does work, I suggest you to not override the whole shipping.js file, but extending it, like itself extends the Magento_Ui/js/form/form (Component). Then you should be able to just override the setShippingInformation() function.

  • For #1. isVisible: ko.observable(false) or isVisible: ko.observable(!quote.isVirtual( )) worked for me. – A. Martz Jan 18 '17 at 23:24
  • For #1. isVisible: ko.observable(false) or isVisible: ko.observable(!quote.isVirtual( )) worked for me. #2. Yes, this would actually work by overriding the call to stepNavigator.next() in setShippingInformation() method. I end up doing it differently though, i created the same billing address fields in the Shipping Step and used them for that so, in my case, i didn't need the extra checkout step. Sorry for the duplicate, i hit enter accidentally :/ – A. Martz Jan 18 '17 at 23:30
