I'm pretty new to Magento in general and just started working with Magento 2.

Here is my question - How to show prices for all out of stock products?

There is this topic: Magento 2 : How To Show Price of "out of stock" Products

And apparently it works, but half of the instructions don't make sense to me. After creating custom module, what should I do with it? Should I change anything else anywhere?


  • Did you enable your module?

  • Good question. I'm not sure how to do it :) Feb 16, 2017 at 2:21
  • run php bin/magento setup:upgrade command to activate your module Feb 16, 2017 at 4:51
  • Fatal error: Uncaught RuntimeException: Can't create directory /var/www/html/generated/code/Magento/Directory/Helper/Data/. in [Magento\Directory\Helper\Data\Proxy] in /var/www/html/vendor/magento/framework/Code/Generator.php:115 Stack trace: #0 /var/www/html/vendor/magento/framework/Code/Generator/Autoloader.php(35): Magento\Framework\Code\Generator->generateClass('Magento\\Directo...') #1 [internal function]: Magento\Framework\Code\Generator\Autoloader->load('Magento\\Directo...') #2 [internal function]: spl_autoload_call('Magento\\Directo...') #3 /var/www/html/vendor/magento/framework/Objec

You need to create your custom module using below code

Let say module name Custom_Outofstock

So create folder in app/code

Create registration.php file at app/code/Custom/Outofstock/registration.php

Add below code to it:



Create module.xml at app/code/Custom/Outofstock/etc/module.xml

Add below code to it:

<?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="Custom_Outofstock" setup_version="2.0.0">

Now create file suggested in this answer given By Sohel Rana as below

Create di.xml at app/code/Custom/Outofstock/etc/di.xml

Add below code to it:

<?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\Catalog\Pricing\Render\FinalPriceBox" type="Custom\Outofstock\Pricing\Render\FinalPriceBox" />

Create Price render file FinalPriceBox.php at app/code/Custom/Outofstock/Pricing/Render/FinalPriceBox.php

Add below code to it:

namespace Custom\Outofstock\Pricing\Render;

use Magento\Msrp\Pricing\Price\MsrpPrice;
use Magento\Framework\Pricing\Render\PriceBox as BasePriceBox;

class FinalPriceBox extends \Magento\Catalog\Pricing\Render\FinalPriceBox
    protected function _toHtml()
        $result = parent::_toHtml();

        if(!$result) {
            $result = BasePriceBox::_toHtml();
            try {
                /** @var MsrpPrice $msrpPriceType */
                $msrpPriceType = $this->getSaleableItem()->getPriceInfo()->getPrice('msrp_price');
            } catch (\InvalidArgumentException $e) {
                return $this->wrapResult($result);

            //Renders MSRP in case it is enabled
            $product = $this->getSaleableItem();
            if ($msrpPriceType->canApplyMsrp($product) && $msrpPriceType->isMinimalPriceLessMsrp($product)) {
                /** @var BasePriceBox $msrpBlock */
                $msrpBlock = $this->rendererPool->createPriceRender(
                        'real_price_html' => $result,
                        'zone' => $this->getZone(),
                $result = $msrpBlock->toHtml();

            return $this->wrapResult($result);

        return $result;

Now run below command to enable module:

php bin/magento setup:upgrade

Flush cache using below command:

php bin/magento cache:flush
  • Thanks for the answer! However, after doing this, all the css was overwritten with default css which came with theme. And products are not displaying whatsoever, instead I get this message: "We're sorry, an error has occurred while generating this email". In exception log i have this message: "[2017-02-13 17:11:58] main.CRITICAL: exception 'Magento\Framework\Exception\LocalizedException' with message 'The element 'product.info.options' already has a child with alias 'default'' in /home/uspatriot/public_html/vendor/magento/framework/Data/Structure.php:611" Any ideas what happened?

  • Actually, after enabling developer mode, then disabling it, and then enabling production mode, this is the error I get now: "Fatal error: Class 'Vendor\Module\Pricing\Render\FinalPriceBox' not found in /home/uspatriot/public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93" Feb 16, 2017 at 18:22
  • So, I figured there was a mistake in di.xml. After changing type from "Vendor\Module\Pricing\Render\FinalPriceBox" to "Custom\Outofstock\Pricing\Render\FinalPriceBox", and re-enabling production mode, it all works now! Feb 16, 2017 at 18:45
  • Yes that is error I forgot to modify it. I have updated code thanks for acknowledge Feb 17, 2017 at 5:45
  • Is there any modification to show "as low as" price only of "in stock" products on configurable product? magento.stackexchange.com/questions/181053/…
