In this blog, we are going to teach you how to restrict payment methods by attribute or category in Magento 2.
It is highly essential to learn to restrict payment methods. As with this you can provide a seamless checkout experience to your customers and elevate the sales of specific products or categories.
This will lead to elevated customer satisfaction and effective management of payment methods.
Follow these steps and accurately restrict payment methods by attribute or category.
Step-by-step Process to Restrict Payment Methods by Attribute or Category
Take a look at \Magento\Payment\Model\MethodList. The constructor has an $additionalChecks argument allowing you to pass in additional custom checks to restrict specific payment methods. etc/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">
<!-- Specify a custom check where `your_custom_restriction` is a unique value -->
<type name="Magento\Payment\Model\MethodList">
<arguments>
<argument name="additionalChecks" xsi:type="array">
<item name="your_custom_restriction" xsi:type="string">your_custom_restriction</item>
</argument>
</arguments>
</type>
<!-- Here we specify the class responsible for handling the check specified in the previous block -->
<type name="Magento\Payment\Model\Checks\SpecificationFactory">
<arguments>
<argument name="mapping" xsi:type="array">
<item name="your_custom_restriction" xsi:type="object">Vendor\PaymentRestriction\Model\YourCustomRestriction</item>
</argument>
</arguments>
</type>
</config>
In etc/catalog_attributes.xml we also need to tell Magento to load our custom attribute value in the product object when we call getProduct() on the quote item.
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/catalog_attributes.xsd">
<group name="quote_item">
<attribute name="disable_some_method"/>
</group>
</config>
The class Model/YourCustomRestriction.php will make the decision to include/exclude the payment method. Our isApplicable() method should return true or false if you want to allow or block the payment method. In the below mentioned example, first, I checked if the payment is Braintree (if not, we immediately return true). If it is, I iterated over all items in the cart, and if one of the items has the attribute disable_some_method set to yes, we break from the loop and return true, which in turn returns false, preventing the payment method from being used.
<?php
declare(strict_types=1);
namespace Vendor\PaymentRestriction\Model;
use Magento\Payment\Model\Checks\SpecificationInterface;
use Magento\Payment\Model\MethodInterface;
use Magento\Quote\Model\Quote;
use PayPal\Braintree\Model\Ui\ConfigProvider;
class YourCustomRestriction implements SpecificationInterface
{
/**
* @param MethodInterface $paymentMethod
* @param Quote $quote
* @return bool
*/
public function isApplicable(MethodInterface $paymentMethod, Quote $quote)
{
if ($paymentMethod->getCode() === ConfigProvider::CODE && $this->hasRestrictedItems($quote)) {
return false;
}
return true;
}
/**
* @param Quote $quote
* @return bool
*/
private function hasRestrictedItems(Quote $quote)
{
$hasRestrictedItems = false;
/** @var \Magento\Quote\Api\Data\CartItemInterface $item */
foreach ($quote->getAllItems() as $item) {
if ($item->getProduct()->getDisableSomeMethod()) {
$hasRestrictedItems = true;
break;
}
}
return $hasRestrictedItems;
}
}
