Magento 2 Hide price for out of stock products in product page

Question

I saw the same question for magento 1.9 but I don't know how to hide price for out of stock products in product pages for magento 2.2.

I think i should override the 'default.phtml' file in path

module-catalog/view/base/templates/product/price/amount

but i don't know how.

Could anyone help me?

Answer 1

You have to override the file final_price.phtml in your current theme. final_price.phtmlinstead to have all prices cases:

1)

app/design/frontend/{Theme}/{name}/Magento_Catalog/templates/product/price/final_price.phtml

2)

Then update the content with this : // I added Three parts of code commented in: 1), 2), 3).

<?php
/**

 * See COPYING.txt for license details.
 */

// @codingStandardsIgnoreFile

?>

<?php
/** @var \Magento\Catalog\Pricing\Render\FinalPriceBox $block */

$productId = $block->getSaleableItem()->getId();

//1) Added this part
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productStockObj = $objectManager->get('Magento\CatalogInventory\Api\StockRegistryInterface')->getStockItem($productId);

/** ex: \Magento\Catalog\Pricing\Price\RegularPrice */
/** @var \Magento\Framework\Pricing\Price\PriceInterface $priceModel */
$priceModel = $block->getPriceType('regular_price');

/** ex: \Magento\Catalog\Pricing\Price\FinalPrice */
/** @var \Magento\Framework\Pricing\Price\PriceInterface $finalPriceModel */
$finalPriceModel = $block->getPriceType('final_price');
$idSuffix = $block->getIdSuffix() ? $block->getIdSuffix() : '';
$schema = ($block->getZone() == 'item_view') ? true : false;
?>
<?php if ($productStockObj->getIsInStock()):?> //2) Added this part
<?php if ($block->hasSpecialPrice()): ?>
    <span class="special-price">
        <?php /* @escapeNotVerified */ echo $block->renderAmount($finalPriceModel->getAmount(), [
            'display_label'     => __('Special Price'),
            'price_id'          => $block->getPriceId('product-price-' . $idSuffix),
            'price_type'        => 'finalPrice',
            'include_container' => true,
            'schema' => $schema
        ]); ?>
    </span>
    <span class="old-price">
        <?php /* @escapeNotVerified */ echo $block->renderAmount($priceModel->getAmount(), [
            'display_label'     => __('Regular Price'),
            'price_id'          => $block->getPriceId('old-price-' . $idSuffix),
            'price_type'        => 'oldPrice',
            'include_container' => true,
            'skip_adjustments'  => true
        ]); ?>
    </span>
<?php else: ?>

        'price_id'          => $block->getPriceId('product-price-' . $idSuffix),
        'price_type'        => 'finalPrice',
        'include_container' => true,
        'schema' => $schema
    ]); ?>
<?php endif; ?>

<?php if ($block->showMinimalPrice()): ?>
    <?php if ($block->getUseLinkForAsLowAs()):?>
        <a href="<?= /* @escapeNotVerified */ $block->getSaleableItem()->getProductUrl() ?>" class="minimal-price-link">
