Allow HTML tags in Bank Tranfer Payment instructions

Question

Default Magento payment method "Bank Tranfer" does not allow using HTML tags in Instructions text.

How can I change that?

Answer 1

As I understood you want to add some HTML tags to Bank transfer Payment method.

By default Magento escapeHtml when rendering Instruction for COD and Bank transfer Payment.

We need to Create a small module which will override getInstructions function.

let's create a module Pawan_Instructions.

app/code/Pawan/Instructions/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Pawan_Instructions',
__DIR__
);

app/code/Pawan/Instructions/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Pawan_Instructions" setup_version="1.0.0">
   </module>
</config>

app/code/Pawan/Instructions/etc/frontend/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">
    <preference for="Magento\OfflinePayments\Model\InstructionsConfigProvider" type="Pawan\Instructions\Model\Rewrite\InstructionsConfigProvider" />
</config>

app/code/Pawan/Instructions/Model/Rewrite/InstructionsConfigProvider.php

<?php

namespace Pawan\Instructions\Model\Rewrite;

class InstructionsConfigProvider extends \Magento\OfflinePayments\Model\InstructionsConfigProvider

{
    public function getInstructions($code)
    {
        if($code == 'banktransfer'){//check payment method is banktransfer
            return nl2br($this->methods[$code]->getInstructions());// removed escapeHtml function!
        }else{
            return nl2br($this->escaper->escapeHtml($this->methods[$code]->getInstructions()));
        }
    }

}

Final Result will be:

Admin

Note: I have checked and allow html tag for only banktransfer code, if you want for both, you can skip If condition.
