I am trying to override Magento Payment Helper data in my extension but it's not working.

I have overriden by using the preference method.

I have put below code in app/code/Demo/PaymentTest/etc/di.xml

<preference for="Magento\Payment\Helper\Data" type="Demo\PaymentTest\Helper\Data" />

Here is my Helper code

namespace Demo\PaymentTest\Helper;
class Data extends \Magento\Payment\Helper\Data
    public function getStoreMethods($store = null, $quote = null)

I am trying to override getStoreMethods method in my helper but it's not calling it.

Can you please tell me what am I doing wrong?

  • What are you trying to achieve ? Depending on the reason why you want to rewrite that method using plugins would be more appropriate Jan 2, 2017 at 11:30

    @SanjayJethva, what Magento version do you use? Since Magento 2.1.3 \Magento\Payment\Helper\Data::getStoreMethods is deprecated and doesn't call anymore, use \Magento\Payment\Model\PaymentMethodList::getActiveList instead

If you want to rewrite payment method, I suggest you use a plugin.

Create the following di.xml in the etc folder of your module:

    <type name="Magento\Payment\Helper\Data">
        <plugin name="restrictPaymentMethods" type="Demo\PaymentTest\Plugin\RestrictPaymentMethods" sortOrder="1" />

Then create Plugin\RestrictPaymentMethods.php :


namespace Demo\PaymentTest\Plugin;

class RestrictPaymentMethods

    public function afterGetStoreMethods(\Magento\Payment\Helper\Data $subject, $result)
        // $result will contain the original result
        // You can modify the $result array to restrict the payment methods
