Hi @robbiefowler
The template responsible for rendering price on a page /vendor/magento/module-catalog/view/base/templates/product/price/amount/default.phtml , however it renders price amount with currency symbol as you noticed. Indeed this is something needs to be addressed for future releases.
Suggestion is to address this issue with invalid snippet by adding custom "Offer" schema.
In order to do that we have to look into the /vendor/magento/module-catalog/view/base/templates/product/price/amount/default.phtml and find a way to disable "Offer" from the template. Likely Magento\Catalog\Pricing\Render\FinalPriceBox to disable schema usage:
di.xml
<type name="Magento\Catalog\Pricing\Render\FinalPriceBox">
<plugin name="reset_schema" type="Custom\Catalog\Plugin\Product\Pricing\Render\FinalPriceBox"/>
</type>
The Custom\Catalog\Plugin\Product\Pricing\Render\FinalPriceBox class
namespace Custom\Catalog\Plugin\Product\Pricing\Render;
/**
* Class FinalPriceBox
* @package Giftsdirect\Catalog\Plugin\Product\Pricing\Render
*/
class FinalPriceBox
{
/**
* @param \Magento\Catalog\Pricing\Render\FinalPriceBox $finalPriceBox
* @param \Magento\Framework\Pricing\Amount\Base $base
* @param array $arguments
* @return array
*/
public function beforeRenderAmount(
\Magento\Catalog\Pricing\Render\FinalPriceBox $finalPriceBox,
\Magento\Framework\Pricing\Amount\Base $base,
array $arguments = []
) {
$arguments['schema'] = false;
return [
$base,
$arguments
];
}
}
By doing this we will disable rendering of invalid Price with Currency inside default.phtml template.
The next step is obviously to provide a solution for valid Offer. We can create a price.phtml template responsible for rendering proper price and currency in a separate tags.
The price.phtml template:
<?php /** @var $block \Custom\Catalog\Block\Product\Price */ ?>
<div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
<meta itemprop="priceCurrency" content="<?php /* @escapeNotVerified */ echo $block->getDisplayCurrencyCode()?>" />
<span class="schema-price" itemprop="price" content="<?php /* @escapeNotVerified */ echo $block->getPrice() ?>"><?php /* @escapeNotVerified */ echo $block->getPrice() ?></span>
<?php echo $block->getChildHtml() ?>
</div>
The Custom\Catalog\Block\Product\Price block:
namespace Custom\Catalog\Block\Product;
use Magento\Framework\Registry;
use Magento\Framework\View\Element\Template;
use Magento\Framework\Pricing\PriceCurrencyInterface;
/**
* Class Price
* @package Custom\Catalog\Block\Product
*/
class Price extends Template
{
/**
* @var PriceCurrencyInterface
*/
protected $priceCurrency;
/**
* @var Registry
*/
protected $registry;
/**
* Price constructor.
* @param Template\Context $context
* @param PriceCurrencyInterface $priceCurrency
* @param Registry $registry
* @param array $data
*/
public function __construct(
Template\Context $context,
PriceCurrencyInterface $priceCurrency,
Registry $registry,
array $data = []
) {
$this->priceCurrency = $priceCurrency;
$this->registry = $registry;
parent::__construct($context, $data);
}
/**
* @return string
*/
public function getDisplayCurrencyCode()
{
return $this->priceCurrency->getCurrency()->getCurrencyCode();
}
/**
* @return float
*/
public function getPrice()
{
/** @var \Magento\Catalog\Model\Product $product */
$product = $this->registry->registry('current_product');
if ($product) {
return round(
$product->getFinalPrice(),
PriceCurrencyInterface::DEFAULT_PRECISION
);
}
return 0;
}
}
This class will give us price of a current product and currency selected on a website.
Finally, the price.phtml together with Block class have to be included into catalog_product_view.xml layout.
<referenceContainer name="product.info.price">
<block class="Custom\Catalog\Block\Product\Price" name="product.info.price.schema" after="product.price.final" template="Custom_Catalog::product/view/price.phtml" />
</referenceContainer>
Similar approach with ListItem schema can be introduced on Catalog Category Pages and Catalog Search result page.
