How to hide the product price for all the pages in magento 2

Question

I have created one module and it has system configuration on the admin side, where the admin has the functionality to enable/disable the module. As per system configuration, I need to hide the price from every place on the front end.

i.e. "catalog, category, wish-list, a related product, up-sell products, cart, checkout, orders, email, account dashboard, etc.."

from everywhere I need to hide the price if the module is enabled.

Is there any global file for the price which can be overridden and add the code for hiding price?

I found one file, But if we override \Magento\Catalog\Pricing\Render\FinalPriceBox and change in wrapResult() function, it works but it will affect only product page and home page not for wish-list and other places.

how can I achieve this functionality? Is anyone have any idea about it?

Answer 1

You will want to create an after plugin on this interface method definition: \Magento\Framework\Pricing\Render\PriceBoxRenderInterface::renderAmount.

You can achieve this by declaring this plugin in a app/etc/Vendor/ModuleName/etc/frontend/di.xml file like it's described here: https://devdocs.magento.com/guides/v2.3/extension-dev-guide/plugins.html#declaring-a-plugin

your plugin should look something like that:

<?php
namespace Vendor\ModuleName\Plugin;

class PriceBoxRenderDisabler {
    public function afterRenderAmount(
         \Magento\Framework\Pricing\Render\PriceBoxRenderInterface $subject,
         $result
    ) {
        //instead of assigning true fetch a value from the config
        $disabled = true;
        if($disabled) {
            return '';
        }

        return $result;
    }
}

After that make sure to run:

bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush
