Magento2 – Add Extra Validation Rules for Existing Shipping Carrier

magento2.3shipping-methodsvalidation

This question is about javascript carrier validation in the checkout page. Depending on the validation result, some carriers may disappear from the displayed list if validation failed for them.

I found documentation about how to Add custom shipping carrier validations. This doc explains how to create from scratch a brand new validator and its own validation rules and how to register them and how to add them in the checkout layout etc. etc…
The point is : I don't need to create a new validator from scratch. The carrier already exists, its validator too. I just want to add an extra validation rule to the existing ones (and fyi, I want this carrier validation to fail if shipping address telephone is not a mobile phone).

Is there a way to inject my own rule in the existing ones (with a mixin maybe ?) or do I have to go through the full creation as described in the official doc, to end up pushing an additional validator for this carrier ?

In Your Shipping Model File(eg. Career.php) add below like condition

public function collectRates(RateRequest $request)
{
        /**
         * here add custom condition and return false if not matching in your condition
         */
        if ($telephone = $quote->getShippingAddress()->getTelephone()) {
            if($telephone != 'your_variable'){
                return false;   // it will not execute furthure code
            }           
        }

        // here your shipping main code
}

One thing you could try is to add a JavaScript mixin:

In requirejs-config.js do:

var config = {
    config: {
        mixins: {
            'mage/validation': {
                'Vendor_Module/js/validation-mixin': true
            }
        }
    }
}

and Vendor_Module/view/frontend/web/js/validation-mixin.js:

define([
    'jquery'
], function ($) {
    "use strict";

    return function () {
        $.validator.addMethod(
            'validate-minimum-age',
            function (value) {
                // Some custom validation stuff here
                return true or false;
            },
            $.mage.__('Your validation error message')
        );
    }
});

This way your validation rule will extend the original JS validation object and will be available everywhere.

try this, just add 'validation' => ['required-entry' => true] like below in LayoutProcessor plugin

'config' => [
                'customScope' => 'shippingAddress',
                'template' => 'ui/form/field',
                'elementTmpl' => 'ui/form/element/input',
                'options' => [],
                'id' => 'custom_field'
            ],
            'dataScope' => 'customfield',
            'label' => 'custom field # :',
            'provider' => 'checkoutProvider',
            'validation' => ['required-entry' => true],
            'visible' => true,
            'sortOrder' => 250,
