Schema markup for Woo - is this code enough for a product card?

Question

Search Engine Optimization

Will information be pulled up in the search through such a code?

<?php
if (isset($product)){
$meta = get_post_meta(get_the_ID());
$_product = new WC_Product(get_the_ID());
if ($_product->regular_price!=NULL){
  $price = $_product->regular_price;
}elseif ($_product->price!=NULL){
  $price = $_product->price;
}
if ( ($price > $_product->sale_price) && ($_product->sale_price!=NULL) ){
  $price = $_product->sale_price;
}
?>
<script type="application/ld+json">
{
  "@context": "http://schema.org/",
  "@type": "Product",
  "name": "<?php echo get_the_title(get_the_ID()); ?>",
  "offers": {
  "@type": "Offer",
  "priceCurrency": "<?php echo get_woocommerce_currency(); ?>",
  "price": "<?php echo $price; ?>",
  "itemCondition" : "http://schema.org/NewCondition",
  "availability" : "http://schema.org/<?php echo $meta['_stock_status'][0] ? 'InStock' : 'OutOfStock'; ?>"
  }
}
</script>
<?php } ?>

If this is not enough or wrong, then how is it right? How do you personally do it?
