I want to override _prepareSpecificInformation method of the Magento\Payment\Block\Info\Cc class
This is Core class.
vendor/magento/module-payment/Block/Info/Cc.php
<?php
namespace Magento\Payment\Block\Info;
/**
* Credit card generic payment info
*
* @api
* @since 100.0.2
*/
class Cc extends \Magento\Payment\Block\Info
{
protected function _prepareSpecificInformation($transport = null)
{
if (null !== $this->_paymentSpecificInformation) {
return $this->_paymentSpecificInformation;
}
$transport = parent::_prepareSpecificInformation($transport);
$data = [];
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Credit Card Type')] = $ccType;
}
if ($this->getInfo()->getCcLast4()) {
$data[(string)__('Credit Card Number')] = sprintf('xxxx-%s', $this->getInfo()->getCcLast4());
}
if (!$this->getIsSecureMode()) {
if ($ccSsIssue = $this->getInfo()->getCcSsIssue()) {
$data[(string)__('Switch/Solo/Maestro Issue Number')] = $ccSsIssue;
}
$year = $this->getInfo()->getCcSsStartYear();
$month = $this->getInfo()->getCcSsStartMonth();
if ($year && $month) {
$data[(string)__('Switch/Solo/Maestro Start Date')] = $this->_formatCardDate($year, $month);
}
}
return $transport->setData(array_merge($data, $transport->getData()));
}
Following is what I have done.
Muk/OrderEmail/etc/di.xml
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Payment\Block\Info\Cc" type="Muk\OrderEmail\Block\Info\Cc"/>
</config>
My custom class
app/code/Muk/OrderEmail/Block/Info/Cc.php
<?php
declare(strict_types=1);
namespace Muk\OrderEmail\Block\Info;
use Magento\Framework\DataObject;
use Magento\Framework\Exception\LocalizedException;
class Cc extends \Magento\Payment\Block\Info\Cc
{
public function __construct
(
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Payment\Model\Config $paymentConfig,
array $data = [])
{
parent::__construct($context, $paymentConfig, $data);
}
/**
* Prepare credit card related payment info
*
* @param DataObject|array $transport
* @return DataObject
* @throws LocalizedException
*/
protected function _prepareSpecificInformation($transport = null)
{
if (null !== $this->_paymentSpecificInformation) {
return $this->_paymentSpecificInformation;
}
$transport = parent::_prepareSpecificInformation($transport);
$data = [];
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Credit Card Type')] = $ccType;
}
if ($this->getInfo()->getCcLast4()) {
$data[(string)__('Credit Card Number')] = sprintf('xxxx-%s', $this->getInfo()->getCcLast4());
}
// Custom information
if ($ccType = $this->getCcTypeName()) {
$data[(string)__('Name on the Card:')] = $this->getInfo()->getCcOwner();
}
// End Custom information
if (!$this->getIsSecureMode()) {
if ($ccSsIssue = $this->getInfo()->getCcSsIssue()) {
$data[(string)__('Switch/Solo/Maestro Issue Number')] = $ccSsIssue;
}
$year = $this->getInfo()->getCcSsStartYear();
$month = $this->getInfo()->getCcSsStartMonth();
if ($year && $month) {
$data[(string)__('Switch/Solo/Maestro Start Date')] = $this->_formatCardDate($year, $month);
}
}
return $transport->setData(array_merge($data, $transport->getData()));
}
}
module.xml
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Muk_OrderEmail">
<sequence>
<module name="Magento_Payment"/>
<module name="Magento_Backend"/>
<module name="Magento_Sales"/>
<module name="Magento_Quote"/>
<module name="Magento_Checkout"/>
</sequence>
</module>
</config>
registration.php
<?php
declare(strict_types=1);
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Muk_OrderEmail',
__DIR__
);
But this override is not working for me.
It turned out that I was overriding a wrong file. Because the \Magento\Payment\Block\Info\Cc was already overridden by a custom module.
After correcting the preference it worked for me.
<?xml version="1.0" encoding="UTF-8"?>

</config>
